Rationale: Rectus sheath hematoma (RSH) is an unusual cause of acute abdominal pain. It is more common in elderly patients on anticoagulation. The diagnosis is often challenging, as it mimics other more common causes of acute abdomen. No standard treatment guidelines exist, presenting therapeutic dilemmas. Herein, we describe a case of spontaneous RSH complicated by deep venous thrombosis (DVT)., Patient Concerns: The patient was a 58-year-old female on follow-up for end-stage renal failure, admitted for management of uremic gastritis, fluid overload state, and bronchopneumonia. On the third day of admission, she developed worsening abdominal pains, associated with dizziness, headaches, hypotension, tachycardia, and desaturation. Abdominal examination revealed tender swelling, with localized guarding., Diagnoses: An urgent abdominal computed tomography scan demonstrated a large complex collection of approximately 12 cm × 10 cm in the left rectus sheath with intraperitoneal extension, consistent with RSH., Interventions: She underwent laparotomy with evacuation of 1.5 L of hematoma. Her postoperative recovery was complicated by the development of DVT on the sixth postoperative day. Due risk of rebleed, the inferior vena cava filter was favored over therapeutic anticoagulation. Her postoperative hospital stay was thereafter unremarkable., Outcomes and Lessons: Although rare, RSH is a potential cause of acute abdomen, particularly among patients on anticoagulation, and can be life-threatening. A high index of suspicion is therefore important for early diagnosis. Clinicians should also appreciate the heightened risk of DVT in the immediate postoperative period despite mechanical anticoagulation., Competing Interests: The authors have no funding and conflicts of interest to disclose., (Copyright © 2024 the Author(s).

To explore the impacts of intestinal flora on cerebral hemorrhage area and brain tissue inflammation in acute hemorrhagic stroke, seventy-two male C57BL/6 mice were randomly separated into 6 groups (n=12), the experimental group (EG, day 1, day 3 and day 7) and the control group (CG, day 1, day 3 and day 7). The mouse cerebral hemorrhage model was established by collagenase injection, and the EG received 0.4 mL fecal filtrate of healthy mice once a day, and the CG received the same amount of normal saline transplantation. The mNSS score, hematoma volume and cerebral edema content were used to evaluate nerve function injury and brain injury degree at each time point after operation. The expressions of inflammatory factors were detected by western blot. We found that at each time point after operation, compared with the CG, nerve function deficit scores of mice in the EG declined (P<0.05), the water content of mice brain tissue in the EG declined (P<0.05), and the protein expressions of inflammatory factors in the EG were decreased (P<0.05). Relative to the CG, the volume of hematoma in the EG declined on day 3 along with day 7 after operation (P<0.05). In conclusion, intestinal flora can reduce cerebral hemorrhage area and brain tissue inflammation, and then improve the performance of nerve function deficit in acute hemorrhagic stroke.

This was the case of a male patient in his 60s, who suddenly collapsed. When the ambulance team arrived, the initial waveform was pulseless electrical activity; accordingly, a supraglottic airway device was inserted, and the patient was immediately transported to a referring hospital. On arrival, the patient resumed spontaneous circulation, the patient was diagnosed with Stanford type B acute aortic dissection and was referred to the author's hospital, where diffuse swelling of the anterior cervical region was revealed. CT performed by the previous hospital revealed compression of the trachea. The cause of cardiac arrest was considered to be severe airway stenosis secondary to a retropharyngeal haematoma associated with Stanford type B acute aortic dissection. Stanford type B acute aortic dissection can be complicated by retropharyngeal haematomas, which can lead to airway obstruction and even cardiac arrest. This condition also requires careful airway examination., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2024. No commercial re-use.

Rarely pelvic hemorrhage events can lead to bladder perforation. We present a 48-year-old female who developed a spontaneous rectal sheath hematoma which perforated her bladder. Her case was monitored with serial MRI imaging and managed with two endoscopic clot resections which demonstrated new epithelialization of the bladder wall across the hematoma point of entry. We conclude that the bladder has an impressive potential to heal and select cases of symptomatic invasive bladder hematomas may be monitored with serial imaging and managed endoscopically.

Hepatic subcapsular hematoma (HSH) is an uncommon complication of pregnancy and is associated with elevated rates of maternal and foetal mortality. The rupture of an HSH is a critical situation that necessitates immediate and timely intervention to prevent loss of life. We present here, a case of a spontaneously ruptured massive HSH caused by preeclampsia. In addition, we conducted a comprehensive review of existing literature, encompassing 49 cases of HSH associated with pregnancy. If a pregnant woman with gestational hypertension experiences right upper abdominal pain with shoulder pain or radiating shoulder pain, it is crucial for her to have an urgent abdominal ultrasound because of the potential development of HSH and/or rupture. Our review of current literature suggests that opting for a caesarean section may offer notable advantages in preventing HSH rupture., Competing Interests: Declaration of conflicting interestsThe authors declare there are no conflicting interests.

Neonatal adrenal haemorrhage (NAH) is more frequently described in neonates due to their relatively larger size and increased vascularity. While most are asymptomatic, they can present with anaemia, jaundice, abdominal mass, scrotal haematoma or more severe complications such as shock and adrenal insufficiency. Scrotal haematoma seen with NAH may be mistaken for other more serious conditions causing acute scrotum. Prompt sonographic examination that includes the bilateral adrenal glands may help to detect NAH early and to avoid unnecessary interventions. Cases of NAH causing ipsilateral inguinal ecchymosis and scrotal haematoma have been reported, but contralateral haematomas are very rare. In this report, we present a unique case of a neonate with an antenatally acquired adrenal haematoma complicated with an acute peripartum rebleeding manifesting as a contralateral scrotal haematoma and inguinal ecchymosis. The NAH was treated conservatively and resolved on follow-up imaging., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2024. No commercial re-use.

This case report illustrates a unique presentation of Lemierre's syndrome precipitated by Fusobacterium necrophorum . This case report describes a 20-year-old patient who developed Lemierre's syndrome secondary to a shoulder hematoma and neck abscess with multiple systemic complications in the absence of tonsillitis or oropharyngeal infection. Two weeks prior to presentation, the patient sustained a right shoulder injury and contracted COVID-19. Due to his Lemierre's syndrome, he developed right internal jugular vein and subclavian vein thrombosis, septic lung emboli, right sided Horner's syndrome, disseminated intravascular coagulation, pelvic collection, septic arthritis of pubic symphysis and osteomyelitis of the right pubic bone, and proximal left femoral shaft. The patient received non-operative and operative management to manage his Lemierre's syndrome including surgical drainage, antibiotics, and anticoagulation; he was discharged following an extended hospital stay. This case report highlights a rare presentation of Lemierre's syndrome secondary to a shoulder hematoma in a COVID-19 positive patient, and its potential systemic and life-threatening complications. Its importance is highly relevant in the context of the COVID-19 pandemic. Further studies are warranted to explore the effect of preceding COVID-19 infections on the microbiological profile in Lemierre's syndrome., Competing Interests: Declaration of Conflicting InterestsThe authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Background and Purpose: The pathophysiological mechanisms underlying brain injury resulting from intracerebral hemorrhage (ICH) remain incompletely elucidated, and efficacious therapeutic interventions to enhance the prognosis of ICH patients are currently lacking. Previous research indicates that MicroRNA-7 (miR-7) can suppress the expression of Nod-like receptor protein 3 (NLRP3), thereby modulating neuroinflammation in Parkinson's disease pathogenesis. However, the potential regulatory effects miR-7 on NLRP3 inflammasome after ICH are yet to be established. This study aims to ascertain whether miR-7 mitigates secondary brain injury following experimental ICH by inhibiting NLRP3 and to investigate the underlying mechanisms., Methods: An ICH model was established by stereotaxically injecting 100 μL of autologous blood into the right basal ganglia of Sprague-Dawley (SD) rats. Subsequently, these rats were allocated into three groups: sham, ICH + Vehicle, and ICH + miR-7, each comprising 18 animals. Twelve hours post-modeling, rats received intraventricular injections of 10 μL physiological saline, 10 μL phosphate, and 10 μL phosphate-buffered saline solution containing 0.5 nmol of miR-7 mimics, respectively. Neurological function was assessed on day three post-modeling, followed by euthanasia for brain tissue collection. Brain water content was determined using the dry-wet weight method. The expression of inflammatory cytokines in cerebral tissues surrounding the hematoma was analyzed through immunohistochemistry and Western blot assays. These cytokines were re-evaluated using Reverse Transcription-Polymerase Chain Reaction (RT-PCR). Moreover, bioinformatics tools were employed to predict miR-7's binding to NLRP3. A wild-type luciferase reporter gene vector and a corresponding mutant vector were constructed, followed by transfection of miR-7 mimics into HEK293T cells to assess luciferase activity., Results: Our study demonstrates that the administration of miR-7 mimics markedly reduced neurological function scores and attenuated brain edema in rats following ICH. A significant upregulation of NLRP3 expression in microglia/macrophage adjacent to the hematoma was observed, substantially reduced after the treatment with miR-7 mimics. Furthermore, this intervention ameliorated neurodegenerative changes and effectively decreased the protein and mRNA levels of pro-inflammatory cytokines, namely TNF-α, IL-1β, IL-6, and Caspase1, in the cerebral tissues proximate to the hematomas. In addition, miR-7 mimics distinctly inhibited the luciferase activity associated with the wild-type reporter gene, an effect not mirrored in its mutant variant., Conclusions: The miR-7 suppressed NLRP3 expression in microglia/macrophage to reduce the production of inflammatory cytokines, leading to conducting certain neuroprotection post-ICH in rats., Competing Interests: Declaration of competing interest The authors declare no conflicts of interest., (Copyright © 2024 Elsevier Inc.

Bilateral femoral neuropathy is rare, especially that caused by bilateral compressive iliopsoas, psoas, or iliacus muscle hematomas. We present a case of bilateral femoral neuropathy due to spontaneous psoas hematomas developed during COVID-19 critical illness. A 41-year-old patient developed COVID-19 pneumonia, and his condition deteriorated rapidly. A decrease in the hemoglobin level prompted imaging studies during his intensive care unit (ICU) stay. Bilateral psoas hematomas were identified as the source of bleeding. Thereafter, the patient complained of weakness in both upper and lower limbs and numbness in the lower limb. He was considered to have critical illness neuropathy and was referred to rehabilitation. Electrodiagnostic testing suggested bilateral femoral neuropathy because of compression due to hematomas developed during the course of his ICU stay. The consequences of iliopsoas hematomas occurring in the critically ill can be catastrophic, ranging from hemorrhagic shock to severe weakness, highlighting the importance of recognizing this entity., (Copyright: © Neurosciences.)

Objective: The impact of first stage labour duration on maternal outcomes is sparsely investigated. We aimed to study the association between a longer active first stage and maternal complications in the early postpartum period., Design: A population-based cohort study., Setting: Regions of Stockholm and Gotland, Sweden, 2008-2020., Population: A cohort of 159 459 term, singleton, vertex pregnancies, stratified by parity groups., Methods: The exposure was active first stage duration, categorised in percentiles. Poisson regression analysis was performed to estimate the adjusted relative risk (aRR) and the 95% confidence interval (95% CI). To investigate the effect of second stage duration on the outcome, mediation analysis was performed., Main Outcome Measures: Severe perineal lacerations (third or fourth degree), postpartum infection, urinary retention and haematoma in the birth canal or ruptured sutures., Results: The risks of severe perineal laceration, postpartum infection and urinary retention increased with a longer active first stage, both overall and stratified by parity group. The aRR increased with a longer active first stage, using duration of <50th percentile as the reference. In the ≥90th percentile category, the aRR for postpartum infection was 1.64 (95% CI 1.46-1.84) in primiparous women, 2.43 (95% CI 1.98-2.98) in parous women with no previous caesarean delivery (CD) and 2.33 (95% CI 1.65-3.28) in parous women with a previous CD. The proportion mediated by second stage duration was 33.4% to 36.9% for the different outcomes in primiparous women. The risk of haematoma or ruptured sutures did not increased with a longer active first stage., Conclusions: Increasing active first stage duration is associated with maternal complications in the early postpartum period., (© 2023 The Authors.

Background: Gastric intramural hematoma is a rare disease. Here we report a case of spontaneous isolated gastric intramural hematoma combined with spontaneous superior mesenteric artery intermural hematoma., Case Presentation: A 75-years-old man was admitted to our department with complaints of abdominal pain. He underwent a whole abdominal computed tomography (CT) scan in the emergency department, which showed extensive thickening of the gastric wall in the gastric body and sinus region with enlarged surrounding lymph nodes, localized thickening of the intestinal wall in the transverse colon, localized indistinct demarcation between the stomach and transverse colon, and a small amount of fluid accumulation in the abdominal cavity. Immediately afterwards, he was admitted to our department, and then we arranged a computed tomography with intravenously administered contrast agent showed a spontaneous isolated gastric intramural hematoma combined with spontaneous superior mesenteric artery intermural hematoma. Therefore, we treated him with anticoagulation and conservative observation. During his stay in the hospital, he was given low-molecular heparin by subcutaneous injection for anticoagulation therapy, and after discharge, he was given oral anticoagulation therapy with rivaroxaban. At the follow-up of more than 4 months, most of the intramural hematoma was absorbed and became significantly smaller, and the intermural hematoma of the superior mesenteric artery was basically absorbed, which also confirmed that the intramural mass was an intramural hematoma., Conclusion: A gastric intramural hematoma should be considered, when an intra-abdominal mass was found to be attached to the gastric wall. Proper recognition of gastric intramural hematoma can reduce the misdiagnosis rate of confusion with gastric cancer., (© 2024. The Author(s).)

Background: The dynamics of blood clot (combination of Hb [hemoglobin], fibrin, and a higher concentration of aggregated red blood cells) formation within the hematoma of an intracerebral hemorrhage is not well understood. A quantitative neuroimaging method of localized coagulated blood volume/distribution within the hematoma might improve clinical decision-making., Methods: The deoxyhemoglobin of aggregated red blood cells within extravasated blood exhibits a higher magnetic susceptibility due to unpaired heme iron electrons. We propose that coagulated blood, with higher aggregated red blood cell content, will exhibit (1) a higher positive susceptibility than noncoagulated blood and (2) increase in fibrin polymerization-restricted localized diffusion, which can be measured noninvasively using quantitative susceptibility mapping and diffusion tensor imaging. In this serial magnetic resonance imaging study, we enrolled 24 patients with acute intracerebral hemorrhage between October 2021 to May 2022 at a stroke center. Patients were 30 to 70 years of age and had a hematoma volume >15 cm 3 and National Institutes of Health Stroke Scale score >1. The patients underwent imaging 3×: within 12 to 24 (T1), 36 to 48 (T2), and 60 to 72 (T3) hours of last seen well on a 3T magnetic resonance imaging system. Three-dimensional anatomic, multigradient echo and 2-dimensional diffusion tensor images were obtained. Hematoma and edema volumes were calculated, and the distribution of coagulation was measured by dynamic changes in the susceptibilities and fractional anisotropy within the hematoma., Results: Using a coagulated blood phantom, we demonstrated a linear relationship between the percentage coagulation and susceptibility (R 2 =0.91) with a positive red blood cell stain of the clot. The quantitative susceptibility maps showed a significant increase in hematoma susceptibility (T1, 0.29±0.04 parts per millions; T2, 0.36±0.04 parts per millions; T3, 0.45±0.04 parts per millions; P <0.0001). A concomitant increase in fractional anisotropy was also observed with time (T1, 0.40±0.02; T2, 0.45±0.02; T3, 0.47±0.02; P <0.05)., Conclusions: This quantitative neuroimaging study of coagulation within the hematoma has the potential to improve patient management, such as safe resumption of anticoagulants, the need for reversal agents, the administration of alteplase to resolve the clot, and the need for surgery., Competing Interests: Disclosures None.

Objective: Many studies reported that tranexamic acid (TXA) was effective in reducing surgical blood loss in the perioperative period of medial open wedge high tibial osteotomy (MOWHTO). However, few studies focused on the simple topical use of TXA in MOWHTO, and the modality and dosage of topical use of TXA varied. The purpose of this study was to observe the effect of topical use of low-dose TXA on drainage volume after MOWHTO, and to analyze the related influencing factors., Methods: Data of patients who underwent MOWHTO combined with arthroscopic knee surgery in our department from January 2019 to September 2021 were retrospectively analyzed. A total of 105 patients (38 males and 67 females, aged 57.7 ± 7.5 years) were included in this study who received topical TXA or no TXA. The patients were divided into three groups: control group (39 cases), 0.5 g TXA group (40 cases), 1 g TXA group (26 cases). Postoperative drainage volume, wound healing, incidence of hematoma and deep venous thrombosis (DVT) were observed and analyzed in the three groups. The effects of gender, hypertension and diabetes on postoperative drainage volume were analyzed using a t-test. The correlation between age, body mass index (BMI), osteotomy gap and postoperative drainage volume were analyzed using the Pearson correlation coefficient., Results: The average postoperative drainage volume of the control group was 259.54 ± 226.33 mL, that of the 0.5 g TXA group was 277.18 ± 177.68 mL, and that of the 1 g TXA group was 229.15 ± 219.93 mL. There was no statistically significant difference in postoperative drainage volume among the three groups (F = 0.423, p = 0.656). There was no local hematoma and wound infection in the three groups. The wound fat liquefaction was found in one patient of the control group. The incidence of DVT was 38.9% (7/18) and 57.1% (8/14) in the control group and 0.5 TXA group, respectively. There was no significant difference in the incidence of DVT between the above two groups (p = 0.476). The average postoperative drainage volume of male patients in the three groups was higher than that of female patients, and the differences were statistically significant (p < 0.05). There was no correlation between age, BMI, osteotomy gap and postoperative drainage volume in the three groups (p > 0.05)., Conclusion: Topical use of low-dose TXA has no significant effect on drainage volume after MOWHTO. The drainage volume after MOWHTO in male patients was more than that in female patients. Topical administration of low-dose TXA does not increase postoperative complications, such as DVT and hematoma., (© 2024 The Authors.

Purpose: To evaluate whether the precision of vacuum cup placement is associated with failed vacuum extraction(VE), neonatal subgaleal hemorrhage(SGH) and other VE-related birth trauma., Methods: All women with singleton term cephalic fetuses with attempted VE were recruited over a period of 30 months. Neonates were examined immediately after birth and the position of the chignon documented to decide whether the cup position was flexing median or suboptimal. Vigilant neonatal surveillance was performed to look for VE-related trauma, including subgaleal/subdural hemorrhages, skull fractures, scalp lacerations. CT scans of the brain were ordered liberally as clinically indicated., Results: The VE rate was 5.89% in the study period. There were 17(4.9%) failures among 345 attempted VEs. Thirty babies suffered from subgaleal/subdural hemorrhages, skull fractures, scalp lacerations or a combination of these, giving an incidence of VE-related birth trauma of 8.7%. Suboptimal cup positions occurred in 31.6%. Logistic regression analysis showed that failed VE was associated with a non-occipital anterior fetal head position (OR 3.5, 95% CI 1.22-10.2), suboptimal vacuum cup placement (OR 4.13, 95% CI 1.38-12.2) and a longer duration of traction (OR 8.79, 95% CI 2.13-36.2); while, VE-related birth trauma was associated with failed VE (OR 3.93, 95% CI 1.08-14.3) and more pulls (OR 4.07, 95% CI 1.98-8.36)., Conclusion: Suboptimal vacuum cup positions were related to failed VE but not to SGH and other vacuum-related birth trauma. While optimal flexed median cup positions should be most desirable mechanically to effect delivery, such a position does not guarantee prevention of SGH., (© 2023.

Background: Hematoma expansion (HE) is common and predicts poor outcome in patients with supratentorial intracerebral hemorrhage (ICH). We investigated the predictors and prognostic impact of HE in infratentorial ICH., Methods: We conducted a retrospective analysis of patients with brainstem and cerebellar ICH admitted at seven sites. Noncontrast computed tomography images were analyzed for the presence of hypodensities according to validated criteria, defined as any hypodense region strictly encapsulated within the hemorrhage with any shape, size, and density. Occurrence of HE (defined as > 33% and/or > 6-mL growth) and mortality at 90 days were the outcomes of interest. Their predictors were investigated using logistic regression with backward elimination at p < 0.1. Logistic regression models for HE were adjusted for baseline ICH volume, antiplatelet and anticoagulant treatment, onset to computed tomography time, and presence of hypodensities. The logistic regression model for mortality accounted for the ICH score and HE., Results: A total of 175 patients were included (median age 75 years, 40.0% male), of whom 38 (21.7%) had HE and 43 (24.6%) died within 90 days. Study participants with HE had a higher frequency of hypodensities (44.7 vs. 24.1%, p = 0.013), presentation within 3 h from onset (39.5 vs. 24.8%, p = 0.029), and 90-day mortality (44.7 vs. 19.0%, p = 0.001). Hypodensities remained independently associated with HE after adjustment for confounders (odds ratio 2.44, 95% confidence interval 1.13-5.25, p = 0.023). The association between HE and mortality remained significant in logistic regression (odds ratio 3.68, 95% confidence interval 1.65-8.23, p = 0.001)., Conclusion: Early presentation and presence of noncontrast computed tomography hypodensities were independent predictors of HE in infratentorial ICH, and the occurrence of HE had an independent prognostic impact in this population., (© 2023.

Introduction: Traumatic head injury (THI) poses a significant global public health burden, often contributing to mortality and disability. Intraoperative hypotension (IH) during emergency neurosurgery for THI can adversely affect perioperative outcomes, and understanding associated risk factors is essential for prevention., Method: A multi-center observational study was conducted from February 10 to June 30, 2022. A simple random sampling technique was used to select the study participants. Patient data were analyzed using bivariate and multivariate logistic regression to identify significant factors associated with intraoperative hypotension (IH). Odds ratios with 95% confidence intervals were used to show the strength of association, and P value < 0.05 was considered as statistically significant., Result: The incidence of intra-operative hypotension was 46.41% with 95%CI (39.2,53.6). The factors were duration of anesthesia ≥ 135 min with AOR: 4.25, 95% CI (1.004,17.98), severe GCS score with AOR: 7.23, 95% CI (1.098,47.67), intracranial hematoma size ≥ 15 mm with AOR: 7.69, 95% CI (1.18,50.05), and no pupillary abnormality with AOR: 0.061, 95% CI (0.005,0.732). CONCLUSION AND RECOMMENDATION: The incidence of intraoperative hypotension was considerably high. The duration of anesthesia, GCS score, hematoma size, and pupillary abnormalities were associated. The high incidence of IH underscores the need for careful preoperative neurological assessment, utilizing CT findings, vigilance for IH in patients at risk, and proactive management of IH during surgery. Further research should investigate specific mitigation strategies., (© 2024. The Author(s).)

Background: The objective of this study was to investigate the clinical, imaging, and outcome characteristics of intracerebral hemorrhage (ICH) caused by structural vascular lesions., Methods: We retrospectively analyzed data from a prospective observational cohort study of patients with spontaneous ICH admitted to the First Affiliated Hospital of Chongqing Medical University between May 2016 and April 2021. Good outcome was defined as modified Rankin Scale score of 0-3 at 3 months. The clinical and imaging characteristics were compared between primary ICH and ICH caused by structural vascular lesions. Multivariable logistic regression analysis was performed to test the associations of etiology with clinical outcome., Results: All patients enrolled in this study were Asian. Compared with patients with primary ICH, those with structural vascular lesions were younger (48 vs. 62 years, P < 0.001), had a lower incidence of hypertension (26.4% vs. 81.7%, P < 0.001) and diabetes (7.4% vs. 16.2%, P = 0.003), and had mostly lobar hemorrhages (49.1% vs. 22.8%). ICH from structural vascular lesions had smaller baseline hematoma volume (8.4 ml vs. 13.8 ml, P = 0.010), had lower mortality rate at 30 days and 3 months (5.8% vs. 12.0%, P = 0.020; 6.7% vs. 14.8%, P = 0.007), and are associated with better functional outcome at 3 months (88% vs.70.3%, P < 0.001)., Conclusions: Compared with primary ICH, ICH due to vascular lesions has smaller hematoma volume and less severe neurological deficit at presentation and better functional outcomes., (© 2023.

Background: Laparoscopic Palomo varicocelectomy using indocyanine green (ICG) fluorescent lymphography (FL) is standardized technique to perform lymphatic sparing and avoid post-operative hydrocele. No data regarding the safety of intratesticular injection of ICG are currently available., Objective: The study aimed to assess the safety and efficacy of this procedure at mid-term follow-up., Study Design: Seventy-two patients (median age 14.5 years) undergoing laparoscopic Palomo varicocelectomy using ICG-FL from January 2019 to July 2022, were enrolled. Operative indication was high-grade varicocele in all patients, associated symptoms in 30/72 (41.7 %) and left testicular hypotrophy in 42/72 (58.3 %). Follow-up included clinical examination at 1, 6, 12 months and scrotal Doppler ultrasonography (US) at 12 months postoperatively to assess varicocele persistence, hydrocele, and injections-related complications., Results: Lymphatic sparing was achieved using ICG-FL in all cases. No intra-operative complications or adverse reactions secondary to ICG occurred. The median follow-up was 22.8 months (range 11-49). Self-limited scrotal hematoma at the injection site occurred in 1/72 (1.4 %). Intratesticular hypoechoic millimetric area was detected at the injection site in 3/72 (4.2 %) on US. This finding disappeared after 1-year observation in 2/3 cases (66.7 %) (Figure). Persistent grade II varicocele was observed in 4/72 (5.5 %), not requiring re-intervention. No hydrocele occurred and 14/22 (63.6 %) with pre-operative hypotrophy showed catch-up growth., Discussion: ICG-FL was clinically safe, with no allergy or systemic adverse reactions to the dye reported in this series. No injury directly related to the injection of the dye was clinically observed, except for self-limiting scrotal hematoma in one patient. A millimetric hypoechoic and avascular area in the body of the left testicle at the injection site was found on scrotal US at 1-year follow-up in 3 patients of our series. This finding does not seem to be clinically relevant as patients were asymptomatic and serum tumor markers were normal in all cases. Furthermore, the hypoechoic area with calcifications resolved 1 year later in 2/3 patients. The absence of evolution of this finding seems to exclude the heteroplastic nature. We hypothesized that this finding may be linked to elevated volume and/or pressure of intratesticular injection. Future prospective study with larger series and longer follow-up is needed to assess long-term testicular outcomes., Conclusion: Laparoscopic Palomo varicocelectomy using ICG-FL reported excellent outcomes with low incidence of varicocele persistence and no post-operative hydrocele. These preliminary data also confirmed safety of intratesticular injection of ICG at mid-term follow-up, without specific risks for both testis and patient., Competing Interests: Conflict of interest The authors declare that there is no conflict of interest., (Copyright © 2023.

Purpose: The Focused Assessment with Sonography for Trauma (FAST) is a tool to rapidly detect intraabdominal and intrapericardial fluid with point-of-care ultrasound. Previous studies have questioned the role of FAST in patients with pelvic fractures. The aim of the present study was to assess the accuracy of FAST to detect clinically significant intraabdominal hemorrhage in patients with pelvic fractures., Methods: We included all consecutive patients with pelvic and/or acetabular fractures treated our Level 1 trauma center from 2009-2020. We registered patient and fracture characteristics, FAST investigations and CT descriptions, explorative laparotomy findings, and transfusion needs. We compared FAST to CT and laparotomy findings, and calculated true positive and negative findings, sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV)., Results: We included 389 patients. FAST had a sensitivity of 75%, a specificity of 98%, a PPV of 84%, and a NPV of 96% for clinically significant intraabdominal bleeding. Patients with retroperitoneal hematomas were at increased risk for laparotomy both because of True-negative FAST and False-positive FAST., Conclusion: FAST is accurate to identify clinically significant intraabdominal blood in patients with severe pelvic fractures and should be a standard asset in these patients. Retroperitoneal hematomas challenge the FAST interpretation and thus the decision making when applying FAST in patients with pelvic fractures., (© 2024. The Author(s).)

BACKGROUND Small bowel hematoma is a rare yet clinically significant condition characterized by the accumulation of blood within the mucosa and submucosa layers of the small intestine wall. It can lead to complications such as bowel obstruction, ischemia, perforation, and even hemorrhagic shock. The etiology of intramural small bowel hematoma is diverse, encompassing factors such as anticoagulant therapy, coagulopathies, vascular disorders, trauma, and underlying systemic conditions. CASE REPORT We present the case of a 67-year-old man with a history of aortic valve replacement who presented with intense abdominal pain. Physical examination revealed generalized abdominal tenderness and black stools upon rectal examination. Laboratory tests indicated coagulopathy with a prolonged thrombin time. A computed tomography scan confirmed the presence of an intramural small bowel hematoma and hemoperitoneum. The patient's condition significantly improved within 48 h under conservative management, including nasogastric tube insertion, continuous monitoring of gastric aspirate, nil per os status, intravenous fluids, and analgesics. Warfarin was temporarily stopped, and fresh frozen plasma was administered for anticoagulation reversal. Heparin infusion was initiated once the INR became within the therapeutic level. CONCLUSIONS The occurrence of spontaneous intramural small bowel hematoma, although rare, demands rapid diagnosis and prompt, well-coordinated management. This case underscores the pivotal role of multidisciplinary collaboration in providing a comprehensive assessment and a tailored approach to treatment. While conservative measures, including careful monitoring and supportive care, have demonstrated favorable outcomes, the consideration of surgical intervention remains crucial, particularly in severe cases.

Background: Sickle cell trait (SCT), the heterozygous form of sickle cell disease, is generally thought of as a benign condition. However, it is possible for those with SCT to have serious complications, especially when they are exposed to high altitudes where oxygen levels are low., Case Report: We present a case of a 41-year-old man with a history of SCT who developed severe epigastric pain and nearly lost consciousness while traveling on a commercial airplane. His twin brother, who also has SCT, had a similar episode in the past and required a splenectomy. A splenic subcapsular hematoma was found in a computed tomography scan of the abdomen and pelvis with intravenous contrast. He was admitted and managed conservatively until his symptoms resolved. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Though SCT is prevalent in our population, the complications that can arise, such as altitude-associated splenic syndrome, have likely not been thoroughly investigated. Physicians should add this condition to their differential if they practice at locations near airports or in areas of higher altitude and if their patients have a past medical history of SCT., Competing Interests: Declaration of competing interest None., (Copyright © 2023 Elsevier Inc.

Background: Acute compartment syndrome can be caused by any condition that increases the pressure of an intracompartmental muscular space, resulting in ischemia, which is a limb-threatening emergency. This case report is the first known documented example of an exogenously injected peptide causing compartment syndrome. The use of natural supplements and holistic therapies is on the rise, specifically, peptide injections. It is important to obtain the history of use and routes of administration of these substances., Case Report: We present a case of a 43-year-old man who presented to the Emergency Department with worsening thigh pain. The patient had injected a "peptide cocktail" into his thigh 3 days prior. Physical examination revealed trace pitting edema of the left leg with moderate muscle spasm and tenderness of the medial aspect of the distal thigh with associated numbness along the medial aspect of the knee. Point-of-care ultrasound detected intramuscular edema and free fluid in the leg. He was found to have acute compartment syndrome of the thigh secondary to the peptide cocktail injection, causing a large hematoma posterior to the adductor magnus. The patient required fasciotomy and hematoma evacuation. He ultimately left against medical advice during his hospitalization. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: In an age when many patients look for supplements to aid with weight loss and muscle growth, it is essential to be aware of peptide injection therapies and the potential complication of compartment syndrome., Competing Interests: Declaration of competing interest The authors have no financial conflicts of interest to disclose., (Copyright © 2023 Elsevier Inc.

Introduction: Endoscopic retrograde cholangiopancreatography (ERCP) is commonly used in gastroenterology wards for both diagnostic and therapeutic purposes. It doesn't however come free of complications. As a matter of fact, complications are reported in up to 10% of patients undergoing ERCP., Patient Concerns: In this article, we report the case of a patient who underwent ERCP and sphincterotomy for choledocholithiasis. Twenty-four hours after the procedure, the patient developed sudden sharp abdominal pain and dropped her hemoglobin levels., Diagnosis: An emergent gastroscopy was done and it ruled out bleeding from the sphincterotomy. Computed tomography of the abdomen showed a large hepatic subcapsular hematoma., Interventions: Blood was urgently transfused and the patient was transferred to the intensive care unit for monitoring., Outcomes: The patient's condition quickly deteriorated despite extensive resuscitative measures, and eventually passed away on day 4 post ERCP., Lessons: Hepatic subcapsular hematoma is a very rare but fatal complication after ERCP and should be ruled out in patients who underwent the procedure and develop sudden abdominal pain with hemodynamic and laboratory instability., Competing Interests: The authors have no funding and conflicts of interest to disclose., (Copyright © 2024 the Author(s).

Poor functional outcome is associated with perihematomal edema (PHE) expansion after intracerebral hemorrhage (ICH). The inflammatory response is crucial for the onset and progression of PHE. This study aimed to determine the connection between admission neutrophil-lymphocyte ratio (NLR) and early PHE development. We retrospectively analyzed patients with ICH admitted to the Chaohu Affiliated Hospital of Anhui Medical University from January 2021 to December 2022. The primary outcome measure was absolute PHE, defined as the volume of the follow-up PHE minus admission PHE. A semiautomated measurement tool (3D Slicer) was used to calculate the volumes of cerebral hematoma and cerebral edema. Spearman's correlation analysis determined the relationship between NLR and absolute PHE. The multiple linear regression model was constructed to analyze the predictive relation of admission NLR on early PHE expansion. A total of 117 patients were included. The median hematoma and PHE volumes on admission were 9.38 mL (interquartile range [IQR], 4.53-19.54) and 3.54 mL (IQR, 1.33-7.1), respectively. The median absolute PHE was 2.26 mL (IQR, 1.25-4.23), and the median NLR was 3.10 (IQR, 2.26-3.86). Spearman's correlation test showed a positive correlation between admission NLR and absolute PHE (r = .548, P < .001). Multiple linear regression analyses suggested that for every 1-unit increase in admission NLR (B = .176, SE = .043, Beta = .275, P < .001), there was a 0.176 mL increase in absolute PHE. Admission neutrophil-to-lymphocyte ratio (NLR) significantly and positively predicted early perihematomal edema (PHE) expansion., Competing Interests: The authors have no funding and conflicts of interest to disclose., (Copyright © 2024 the Author(s).

Spontaneous subcapsular and perirenal hemorrhage, known as Wunderlich syndrome (WS), is a rare clinical manifestation of polyarteritis nodosa (PAN). We report a case of a 48-year-old male with a history of recurrent episodes of leg muscle tenderness and dysesthesia, bilateral flank pain, painful nodular skin lesions in the lower limbs, weight loss, and difficult-to-control arterial hypertension. The abdominopelvic computed tomography angiography showed a large left perirenal hematoma, leading to the patient's admission to the intensive care unit. After the exclusion of infectious or neoplastic foci, the patient was diagnosed with PAN and started intravenous methylprednisolone pulses with a good response. Since WS is a rare initial clinical manifestation of PAN, an early diagnosis and aggressive treatment will significantly improve clinical outcomes.

Spontaneous gastric intramural haematoma is an uncommon complication associated with anticoagulant therapy. A patient receiving chronic warfarin for paroxysmal atrial fibrillation was admitted due to atrial fibrillation with rapid ventricular response (RVR). An incidental intra-abdominal mass was detected on a CT scan. Following the initiation of the amiodarone infusion, the patient experienced bleeding attributed to warfarin-amiodarone-induced coagulopathy, with no identifiable bleeding source. Subsequent CT scans revealed an enlargement of the intra-abdominal mass, suggesting gastric intramural haematoma. After coagulopathy reversal, the haematoma is managed conservatively. Our case underscores the potential for incidental bleeding even when the international normalised ratio is within the normal range in patients on chronic warfarin therapy. When managing such patients with atrial fibrillation with RVR, physicians should maintain a high index of suspicion for bleeding, emphasising the importance of prompt coagulopathy reversal., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2024.

Background: Acute type A aortic intramural hematoma (ATAIMH) is a variant of acute type A aortic dissection (ATAAD), exhibiting an increased risk of hemopericardium and cardiac tamponade. It can be life-threatening without emergency treatment. However, comprehensive studies of the clinical features and surgical outcomes of preoperative hemopericardium in patients with ATAIMH remain scarce. This retrospective study aims to investigate the clinical features and early and late outcomes of patients who underwent aortic repair surgery for ATAIMH complicated with preoperative hemopericardium., Methods: We investigated 132 consecutive patients who underwent emergency ATAIMH repair at this institution between February 2007 and August 2020. These patients were dichotomized into the hemopericardium (n = 58; 43.9%) and non-hemopericardium groups (n = 74; 56.1%). We compared the clinical demographics, surgical information, postoperative complications, 5-year cumulative survival rates, and freedom from reoperation rates. Furthermore, multivariable logistic regression analysis was utilized to identify independent risk factors for patients who underwent re-exploration for bleeding., Results: In the hemopericardium group, 36.2% of patients presented with cardiac tamponade before surgery. Moreover, the hemopericardium group showed higher rates of preoperative shock and endotracheal intubation and was associated with an elevated incidence of intractable perioperative bleeding, necessitating delayed sternal closure for hemostasis. The hemopericardium group exhibited higher blood transfusion volumes and rates of re-exploration for bleeding following surgery. However, the 5-year survival (59.5% vs. 75.0%; P = 0.077) and freedom from reoperation rates (93.3% vs. 85.5%; P = 0.416) were comparable between both groups. Multivariable analysis revealed that hemopericardium, cardiopulmonary bypass time, and delayed sternal closure were the risk factors for bleeding re-exploration., Conclusions: The presence of hemopericardium in patients with ATAIMH is associated with an elevated incidence of cardiac tamponade and unstable preoperative hemodynamics, which could lead to perioperative bleeding tendencies and high complication rates. However, patients of ATAIMH complicated with hemopericardium undergoing aggressive surgical intervention exhibited long-term surgical outcomes comparable to those without hemopericardium., (© 2024.

Background: Nontraumatic intracerebral hemorrhage (ICH) is independently associated with a long-term increased risk of major arterial ischemic events. While the relationship between ICH location and ischemic risk has been studied, whether hematoma volume influences this risk is poorly understood., Methods: We pooled individual patient data from the MISTIE III (Minimally Invasive Surgery Plus Alteplase for Intracerebral Hemorrhage Evacuation Phase 3) and the ATACH-2 (Antihypertensive Treatment of Acute Cerebral Hemorrhage-2) trials. The exposure was hematoma volume, treated as a continuous measure in the primary analysis, and dichotomized by the median in the secondary analyses. The outcome was a symptomatic, clinically overt ischemic stroke, adjudicated centrally within each trial. We evaluated the association between hematoma volume and the risk of an ischemic stroke using Cox regression analyses after adjustment for demographics, vascular comorbidities, and ICH characteristics., Results: Of 1470 patients with ICH, the mean age was 61.7 (SD, 12.8) years, and 574 (38.3%) were female. The median hematoma volume was 17.3 mL (interquartile range, 7.2-35.7). During a median follow-up of 107 days (interquartile range, 91-140), a total of 30 ischemic strokes occurred, of which 22 were in patients with a median ICH volume of ≥17.3 mL and a cumulative incidence of 4.6% (95% CI, 3.1-7.1). Among patients with a median ICH volume <17.3 mL, there were 8 ischemic strokes with a cumulative incidence of 3.1% (95% CI, 1.7-6.0). In primary analyses using adjusted Cox regression models, ICH volume was associated with an increased risk of ischemic stroke (hazard ratio, 1.02 per mL increase [95% CI, 1.01-1.04]). In secondary analyses, ICH volume of ≥17.3 mL was associated with an increased risk of ischemic stroke (hazard ratio, 2.5 [95% CI, 1.1-7.2]), compared with those with an ICH volume <17.3 mL., Conclusions: In a heterogeneous cohort of patients with ICH, initial hematoma volume was associated with a heightened short-term risk of ischemic stroke., Competing Interests: Disclosures Dr Harris reports stock holdings in Eli LIlly and stock holdings in GlaxoSmithKline.

Background: Page kidney is a rare condition in which an external compression of the kidney as a result of a hematoma or mass causes renal ischemia and hypertension. In a patient with flank pain, elevated blood pressure, and recent trauma, this condition should be considered. Since this condition was first described in 1939, more than 100 case reports have surfaced., Case Report: We describe the case of a 26-year-old man who presented to the Emergency Department with flank pain, vomiting, and elevated blood pressure. A computed tomography scan of the abdomen and pelvis confirmed the presence of a perinephric hematoma, and the interventional radiology team was consulted to resolve the Page kidney. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Symptoms seen in Page kidney may be similar to other more common diagnoses encountered in the emergency department. It is important to maintain a high suspicion and order imaging studies as needed, especially in the setting of trauma, or a recent procedure in the vicinity of the renal parenchyma., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 Elsevier Inc.

Although blood pressure variability (BPV) and reperfusion are associated with parenchymal hematoma (PH) after stroke, the relationship between BPV and PH in atrial fibrillation (AF) patients who are at risk of reperfusion injury with frequent spontaneous recanalization is unknown. This study aimed to investigate whether BPV within the first 48 h is associated with PH within 72 h in patients with AF and stroke in terms of major vessel occlusion status. A total of 131 patients with AF that were admitted within 24 h after stroke onset were enrolled. PH was defined as a confluent hemorrhage with mass effect. The maximum (max), minimum (min), and average blood pressure (BP) during the first 48 h after admission were calculated. BPV was analyzed by using range between maximum and minimum (max-min), successive variation (SV), standard deviation (SD), and coefficient of variation (CV). All parameters were applied for systemic (SBP), diastolic (DBP), and pulse pressure (PP). After adjusting for confounding variables, various BPV parameters were associated with PH, including SBP max (p = 0.0426), SBP SV (p = 0.0006), DBP max-min (p = 0.0437), DBP SV (p = 0.0358), DBP SD (p = 0.0393), PP max-min (p = 0.0478), PP SV (p < 0.0001), PP SD (p = 0.0034), and PP CV (p = 0.0120). The relationship remained significant in patients with a patent major vessel responsible for infarction but not in patients with an occluded major vessel. In conclusion, this study revealed that high BPV was associated with PH in patients with AF and acute stroke, particularly for those with a patent major vessel. The control of BP and BPV after stroke may be considered in patients with AF., (© 2023. The Author(s), under exclusive licence to The Japanese Society of Hypertension.)

Background: Scurvy is an uncommon disease in developed countries caused by deficiency of vitamin C. We present a case of scurvy in a 14-year-old male with autism with both novel presentation and imaging findings. This case had the novel presentation of lower limb deep vein thrombosis (DVT) secondary to compression of the external iliac vein from large bilateral iliac wing subperiosteal hematomas. Subperiosteal hematoma is a well-recognised feature of scurvy but large and bilateral pelvic subperiosteal hematoma causing DVT has not previously been described., Case Presentation: A 14 year old Caucasian male with background of autism and severe dietary restriction presented with lower limb swelling and immobility. He was diagnosed with lower limb DVT. Further investigation revealed an iron deficiency anaemia, and he was found on MRI to have large bilateral subperiosteal iliac hematomata causing compression of the iliac vessels. He improved following treatment with vitamin C replacement and follow-up imaging demonstrated resolution of the DVT and hematoma., Conclusion: DVT is rare in children and when diagnosed should prompt investigation as to the underlying cause. This case demonstrates an unusual cause of DVT and as an unusual presentation of paediatric scurvy., (© 2024. Crown.)

Background: The distal transradial access (dTRA) has become an attractive and alternative access to the conventional transradial access (TRA) for cardiovascular interventional diagnosis and/or treatment. There was a lack of randomized clinical trials to evaluate the effect of the dTRA on the long-term radial artery occlusion (RAO)., Methods: This was a prospective, randomized controlled study. The primary endpoint was the incidence of long-term RAO at 3 months after discharge. The secondary endpoints included the successful puncture rate, puncture time, and other access-related complications., Results: The incidence of long-term RAO was 0.8% (3/361) for dTRA and 3.3% (12/365) for TRA (risk ratio = 0.25, 95% confidence interval = 0.07-0.88, P = 0.02). The incidence of RAO at 24 h was significantly lower in the dTRA group than in the TRA group (2.5% vs. 6.7%, P < 0.01). The puncture success rate (96.0% vs. 98.5%, P = 0.03) and single puncture attempt (70.9% vs. 83.9%, P < 0.01) were significantly lower in the dTRA group than in the TRA group. However, the number of puncture attempts and puncture time were higher in the dTRA group. The dTRA group had a lower incidence of bleeding than the TRA group (1.5% vs. 6.0%, P < 0.01). There was no difference in the success rate of the procedure, total fluoroscopy time, or incidence of other access-related complications between the two groups. In the per-protocol analysis, the incidence of mEASY type ≥ II haematoma was significantly lower in the dTRA group, which was consistent with that in the as-treated analysis., Conclusions: The dTRA significantly reduced the incidence of long-term RAO, bleeding or haematoma., Trial Registration: ClinicalTrials.gov identifer: NCT05253820., (© 2024.

Background: Hematoma expansion (HE) is common in patients with intracerebral hemorrhage (ICH) and associated with a worse outcome. Imaging makers and shorter time from symptom onset are both associated with HE, but prognostic scores based on these parameters individually have not been satisfactory. We hypothesized that a score including both imaging markers of expansion, and time of onset, would improve prediction., Methods: Patients with supratentorial ICH within 6 h after onset were consecutively recruited from six centers between January 2018 and August 2022. Three markers were used: hypodensities, the blend sign, and the island sign. We first defined frequency of imaging markers (FIM) as the relationship between the number of imaging markers and onset-to-CT time (OCT). The time-adjusted FIM was defined as the ratio of the number of imaging markers to the onset-to-initial imaging time. Multivariate analysis was performed to determine the relationship between FIM and HE. Receiver operating curve analysis was used to identify potential threshold values of FIM that optimally predict HE. In addition, the sensitivity, specificity, positive and negative predictive values (PPVs and NPVs), and the area under the curve (AUC) of the optimal cut-off in predicting HE were calculated., Results: In total, 1488 patients were eligible for inclusion, of whom 418 had incident HE. Multivariate analysis showed that age, male sex, baseline Glasgow Coma Scale score, presence of intraventricular hemorrhage, and FIM were independent predictors of HE (odds ratio (OR) = 0.98, 95% confidence interval (CI) = 0.97-0.99; OR = 1.73, 95% CI = 1.28-2.35; OR = 0.87, 95% CI = 0.83-0.92; OR = 0.42, 95% CI = 0.28-0.62; OR = 7.82, 95% CI = 5.86-10.42, respectively). The optimal cut-off point for FIM in predicting HE was 0.63, with sensitivity, specificity, PPV, NPV, and AUC values of 0.69, 0.89, 0.71, 0.88, and 0.83, respectively., Conclusion: The FIM adjusted for time since symptom onset is a significant predictor of HE. Its use may allow improved prediction of those patients with ICH who develop HE, and the score may be clinically applicable in the management of patients with ICH., Competing Interests: Declaration of conflicting interestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Background: Cesarean delivery is a commonly performed surgical procedure worldwide. There is limited good-quality evidence regarding subcuticular skin closure with absorbable sutures in transverse incisions after cesarean delivery., Objective: This study aimed to compare poliglecaprone-25 (3-0) and polyglactin-910 (4-0) sutures for subcuticular skin closure in Pfannenstiel incisions among women undergoing cesarean delivery., Study Design: In this double-blind, single-center, randomized controlled trial among women undergoing cesarean delivery (elective and emergency), 200 women were randomized (Group 1-subcuticular skin closure with poliglecaprone-25 [3-0] vs Group 2-subcuticular skin closure with polyglactin-910 [4-0]). All women received similar preoperative and postoperative care. A sample size of 200 women was selected with the aim of reducing the composite wound complication rate from 15.8% to 3.6% with a power of 0.80 and a 2-tailed α of 0.05. Thus, 90 women were required in each group, but 100 were selected to account for attrition., Results: Composite wound complications (including surgical site infection, hematoma, seroma, need for resuturing or readmission for wound complications) were similar in the 2 groups (Group 1 vs 2: 16 vs 10; P=.293; relative risk, 1.28; 95% confidence interval, 0.91-1.79). Surgical site infection (8 vs 7; P=1.000; relative risk, 1.08; 95% confidence interval, 0.64-1.83), hematoma (1 vs 2; P=.561; relative risk, 0.66; 95% confidence interval, 0.13-3.31), seroma (8 vs 2; P=.052; relative risk, 1.65; 95% confidence interval, 1.17-2.33), need for resuturing (4 vs 3; P=.700; relative risk, 1.15; 95% confidence interval, 0.60-2.22), and need for readmission (4 vs 4; P=1.000) were similar in the 2 groups. Pain score on the visual analog scale at 3 days (3.2±1.0 vs 3.6±1.2) and 6 weeks after operation (1.6±0.8 vs 1.7±0.9;) was significantly lower in Group 1 (P=.023 and P=.033, respectively). There was no difference between observer and patient scar assessment scores measured at 6 weeks after operation (P=.069 and P=.431, respectively)., Conclusion: Poliglecaprone-25 (3-0) and polyglactin-910 (4-0) subcuticular sutures were comparable regarding composite wound complications (surgical site infection, hematoma, seroma, wound separation or re-suturing, need for readmission) and cosmetic appearance (patient scar assessment score & observer scar assessment score) related to skin closure among women undergoing cesarean delivery through a Pfannenstiel incision in nonobese women (average body mass index, 25)., (Copyright © 2023 Elsevier Inc.

Amyloid light-chain (AL) amyloidosis rarely causes colorectal submucosal hematoma. A 76-year-old man presented with a complaint of bloody stool. An initial colonoscopy revealed ulcerative lesions in the descending colon, leading to a diagnosis of ischemic colitis. One month later, he presented with cardiac failure, suspected cardiac amyloidosis, and underwent a second colonoscopy. Although it revealed multiple ulcerative lesions from the ascending to transverse colon, biopsy samples did not confirm amyloid deposition. He underwent a third colonoscopy 3 weeks later due to recurrent bloody stool. It showed multiple submucosal hematomas from the ascending to descending colon concomitant with ulcerative lesions in the descending colon and multiple elevated lesions in the sigmoid colon. Biopsy samples confirmed amyloid deposition. Using a systemic search, multiple myeloma with AL amyloidosis was diagnosed. Colorectal submucosal or intramural hematomas are conditions usually encountered in trauma, antithrombotic use, or coagulation disorders. Based on our review of the literatures, we identified several differences between colorectal intramural hematoma caused by amyloidosis and those caused by other etiologies. We believe that amyloidosis should be considered when relatively small and multiple colorectal hematomas, not restricted to the sigmoid colon, and with concomitant findings of erosions and ulcers, are observed., (© 2023.

The inflammatory mechanism of intracerebral hemorrhage (ICH) has been widely studied, and it is believed that the regulation of this mechanism is of great significance to the prognosis. In the early stage of the acute phase of ICH, the release of a large number of inflammatory factors around the hematoma can recruit more inflammatory cells to infiltrate the area, further release inflammatory factors, cause an inflammatory cascade reaction, aggravate the volume of cerebral hematoma and edema and further destroy the blood-brain barrier (BBB), according to this, the crosstalk between cells may be of great significance in secondary brain injury (SBI). Because most of the cells recruited are inflammatory immune cells, this paper mainly discusses the cells based on the inflammatory mechanism to discuss their functions after ICH, we found that among the main cells inherent in the brain, glial cells account for the majority, of which microglia are the most widely studied and it can interact with a variety of cells, which is reflected in the literature researches on its pathogenesis and treatment. We believe that exploring multi-mechanism and multi-cell regulated drugs may be the future development trend, and the existing research, the comparison and unification of modeling methods, and the observation of long-term efficacy may be the first problem that researchers need to solve., (Copyright © 2023 IBRO.

Background: Left atrial myxoma is the most common benign tumor, with the growth rate remaining unknown because specific symptoms do not present until the tumor grows to a certain size. Early surgical management is performed in most cases once it is detected by physicians. Despite cardiac myxomas commonly being perceived as slow-growing tumors, rapid enlargement of myxomas has been reported., Case Presentation: A 64-year-old woman was referred to our hospital with a diagnosis of a left atrial tumor. The pointed tumor changed morphologically in a few hours, and her respiratory condition, which had been normal at admission, suddenly deteriorated. Emergent surgery was performed, and the diagnosis was myxoma with multiple intratumor massive hematomas. The patient recovered uneventfully and was discharged on postoperative day 12 without any complications., Conclusions: We report an extremely rare case of left atrial myxoma rapidly expanded due to acute multiple hemorrhages within itself. Massive internal hemorrhage alters the size, shape, and fragility of the tumor. We should recognize the potential risk of internal hemorrhage that may lead to acute deterioration of the so-called "slow-growing benign" tumors, such as myxomas., (© 2024. The Author(s).)

Subgaleal hematoma, characterised by blood accumulation between the galea aponeurosis and the periosteum, is rarely reported in adults. A man with liver cirrhosis experienced airway obstruction secondary to an extensive subgaleal hematoma due to superficial temporal artery injuries. Within 6 hours after injury, swelling of the patient's head and neck was noted, which was associating with inspiratory wheezing and paradoxical breathing, thus necessitating emergency intubation. The branches of the superficial temporal artery were identified as the bleeding source via angiography. Subsequently, endovascular embolisation was successfully performed. This case highlights a rare association between airway obstruction and subgaleal hematoma, originating from injuries of the superficial temporal artery in an adult patient with severe coagulopathy. Airway obstruction was secondary to the hematoma progression into the facial and neck regions. It is crucial to identify and address alternative bleeding sources if conservative treatments or initial interventions for subgaleal hematomas are proven ineffective., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2024.

Objectives: Most published reports on lobular hemorrhage in cerebral amyloid angiopathy (CAA) include patients diagnosed only by imaging studies. This study analyzed patients with subcortical hemorrhage histologically diagnosed as CAA or non-CAA (hypertensive)., Methods: This is a retrospective study analyzing data from 100 craniotomy cases. Tissue of hematoma cavity wall was collected for histological investigation in hematoma removal by surgery in patients with subcortical hemorrhage. Statistical analyses of blood pressure, hematoma location and volume, outcome, and mortality was performed in CAA and non-CAA groups., Results: There were 47 CAA and 53 non-CAA cases, and average age was significantly older in the CAA group (p < 0.01). Blood pressure was significantly lower (p < 0.01) but hematoma volume was significantly greater (p < 0.05) in the CAA group. Rebleeding occurred in two CAA cases and one non-CAA case, but no re-operations were required. Average score of modified Rankin Scale, which is used to measure the degree of disability in patients who have had a stroke, at three months after surgery was not significantly different between the two groups (CAA: 3.94 ± 1.28, non-CAA: 3.58 ± 1.50). There were seven deaths in the CAA and six in the non-CAA group, and intraventricular hemorrhage highly complicated in the death cases in both groups. In the CAA group, average age of the fatal cases was significantly older than that of the surviving cases (p < 0.05) and six cases demonstrated dementia before onset of hemorrhage., Conclusions: Surgical removal of a subcortical hemorrhage caused by CAA is not contraindicated. However, age > 80 years, complication with intraventricular hemorrhage, hematoma volume ≥ 50 ml, and dementia before onset of hemorrhage contribute to high mortality, and craniotomy should be carefully considered for such patients. A limitation of this study is that comparison between CAA and non-CAA groups was performed in the patients with only surgically indicated ICH, and does not evaluate entire ICH cases with CAA. However, this study appropriately compared pathologically diagnosed CAA and non-CAA in patients with moderate to severe lobular ICH with surgical indications., (Copyright © 2023.

Objective: We investigated the relationship between using a rotary compression device (RCD) with or without sterile gauze and adverse events in transradial access (TRA) for coronary intervention., Methods: In this study involving 933 patients at Yueyang Hospital, we recorded TRA-related adverse events, such as bleeding, forearm hematoma, swollen palms, radial artery occlusion (RAO) and others. Logistic regression was applied to assess the association., Results: Of the 933 patients (66.7% males, average age 67.8 years), 511 used RCD with sterile gauze, whereas 422 used RCD without sterile gauze. The most common adverse events were radial artery hemorrhage (7.4%), hand swelling (4.8%) and RAO (4.6%). Logistic regression analysis revealed that the use of RCD with sterile gauze was associated with a higher prevalence of adverse events [odds ratio (OR), 1.74; 95% confidence interval (CI), 1.22-2.49), even with the adjustment of potential confounders (OR, 1.71; 95% CI, 1.19-2.45). Moreover, patients who used RCD with sterile gauze exhibited an increased risk of radial artery hemorrhage (OR, 1.83; 95% CI, 1.07-3.12), swelling of the hand (OR, 1.96; 95% CI, 1.02-3.75) and RAO (OR, 3.17; 95% CI, 1.49-6.72)., Conclusions: The use of RCD with sterile gauze in TRA is associated with a higher incidence of adverse events., (Copyright © 2023 The Author(s).

Objectives: Surgical procedures for vaginal hydroceles have been varied with the aims of preventing recurrence, hematoma and edema formation and providing a better cosmetic outcome. The Jaboulay's procedure remains a preferred procedure owing to its simplicity and good long term outcome. However, sac eversion during the procedure leads to scrotal edema and mass sensation due to remnant sac in cases of large or secondary hydrocele sacs. Sac excision in these cases may provide better outcomes by removing the excess tissue. We aimed to compare the postoperative outcome after Jaboulay's procedure and harmonic scalpel excision of the sac in terms of scrotal edema, hematoma formation and the final cosmetic appearance., Patients and Methods: 72 adult patients with vaginal hydrocele were randomized into two groups, who underwent harmonic scalpel sac excision and Jaboulay's procedure respectively, performed by a single surgeon. Preoperatively, patient demographics were noted. Postoperatively, data was recorded on the 1st day, 3rd day & 10th day about postoperative complications, and outcomes. Satisfaction on final cosmetic outcome was compared between the groups at the 3rd month., Results: Post operative edema and sensation of mass in the scrotum were more (but not significant) in the Jaboulay's procedure group. Seroma and wound infection rates were similar in both groups. Patient satisfaction on cosmesis was better in the sac excision group., Conclusion: Hydrocelectomy with excision of the sac using a harmonic scalpel results in a lower incidence of postoperative oedema and better patient satisfaction in terms of cosmetic outcome compared to Jaboulay's procedure in the treatment of adult hydroceles., (© 2023.

Background: Patients with spontaneous intracerebral hemorrhage (sICH) are at high risk for venous thromboembolism (VTE). The administration of mechanical and pharmacological VTE prophylaxis after sICH is important but challenging. The safety and efficacy of the optimal anticoagulant dose, timing, and type of VTE chemoprophylaxis in cases of sICH are still unclear, and clinicians are concerned that it may lead to cerebral hematoma expansion, which is associated with poor prognosis. Through this literature review, we aim to summarize the latest guidelines, recommendations, and clinical research progress to support evidence-based treatment strategies., Review Summary: It has been proven that intermittent pneumatic compression can effectively reduce the risk of VTE and should be used at the time of hospital admission, whereas gradient compression stockings or lack of prophylaxis in sICH cases are not recommended by current guidelines. Studies regarding pharmacological VTE prophylaxis in patients with ICH were reviewed and summarized. Prophylactic anticoagulation for VTE in patients with ICH seems to be safe and was not associated with cerebral hematoma expansion. Meanwhile, the prophylactic efficacy of anticoagulation for pulmonary embolism seems to be more obvious than that of deep vein thrombosis in patients with ICH., Conclusions: Clinicians should pay attention to the prevention and management of VTE after sICH. Intermittent pneumatic compression should be applied to patients with sICH on the day of hospital admission. After documentation of bleeding cessation, early initiation of pharmacological VTE prophylaxis (24 h to 48 h from sICH onset) seems to be safe and effective in pulmonary embolism prophylaxis., Competing Interests: The authors declare no conflict of interest., (Copyright © 2023 Wolters Kluwer Health, Inc.

Background: Prestroke physical activity (PA) has been linked to improved outcomes after intracerebral haemorrhage (ICH), but its association with ICH volume is unknown. We aimed to investigate associations of prestroke PA with location-specific haematoma volume and the clinical outcome of ICH., Methods: All patients with primary ICH, admitted to three hospitals between 2014 and 2019, were included. Patients performing light PA ≥4 hour/week the year before stroke were considered physically active. Haematoma volumes were assessed from admission brain imaging. Adjusted associations were estimated using multivariate linear and logistic regression models. Haematoma volume was explored as mediator to the relationship between prestroke PA and mild stroke severity (0-4 points on the National Institutes of Health Stroke Scale), a good 1-week functional status (0-3 points on the modified Rankin Scale) and 90-day survival. Average direct effects (ADE) and average causal mediation effects (ACME) were computed., Results: Of 686 primary ICH cases, 349 were deep, 240 lobar and 97 infratentorial. Prestroke PA predicted smaller haematoma volumes in deep ICH (β=-0.36, SE=0.09, p<0.001) and lobar ICH (β=-0.23, SE=0.09, p=0.016). Prestroke PA was also associated with mild stroke severity (OR 2.53, 95% CI 1.59 to 4.01), a good 1-week functional status (OR 2.12, 95% CI 1.37 to 3.30) and 90-day survival (OR 3.48, 95% CI 2.06 to 5.91). Haematoma volume partly mediated the relationships between PA and stroke severity (ADE 0.08, p=0.004; ACME 0.10, p<0.001), 1-week functional status (ADE 0.07, p=0.03; ACME 0.10, p<0.001) and 90-day survival (ADE 0.14, p<0.001; ACME 0.05, p<0.001)., Conclusions: Light PA ≥4 hour/week prior to ICH was associated with smaller haematoma volumes in deep and lobar locations. Physically active patients with ICH had a higher likelihood of mild stroke, a good 1-week functional status and 90-day survival, in part mediated by smaller haematoma volumes on admission., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2023.

Elevated pulse pressure is commonly observed in cardiovascular diseases and serves as an independent risk factor and predictor of cardiac mortality. However, the role of pulse pressure in patients with spontaneous intracerebral hemorrhage (ICH) remains uncertain. This study aimed to investigate the association between admission pulse pressure and clinical characteristics, including in-hospital outcomes, in ICH patients. We retrospectively analyzed the data of 292 ICH patients, categorizing them into two groups based on admission wide pulse pressure: > 100 mmHg (n = 60) and ≤ 100 mmHg (n = 232). Clinical characteristics and in-hospital outcomes were compared between the groups, and multivariate logistic regression was performed to identify independent factors. Patients with wide pulse pressure were older, had lower Glasgow Coma Scale, larger intraparenchymal hematomas, more pronounced midline shifts, and higher rates of intraventricular hematoma extension and hydrocephalus. These patients also experienced higher frequencies of craniotomy or craniectomy and longer hospital stays. Multivariate logistic regression revealed that pulse pressure > 100 mmHg was significantly associated with increased in-hospital mortality (odds ratio 4.31, 95% confidence interval 1.12-16.62, p = 0.03), but not with a modified Rankin Scale score of 4-6. In conclusion, our investigation demonstrates a significant relationship between admission pulse pressure and severe clinical characteristics in ICH patients. Importantly, a wider pulse pressure is linked to heightened in-hospital mortality. These results underscore the necessity for customized strategies to predict patient outcomes in this population. Further research is essential to explore potential therapeutic interventions targeting pulse pressure to improve clinical outcomes for ICH patients., (© 2023.

BACKGROUND Inferior shoulder dislocation is a rare type of glenohumeral joint dislocation. A serious complication to shoulder dislocation is axillary artery injury, which should be taken into consideration early to avoid potentially permanent damage. Literature on artery injury following inferior shoulder dislocation is sparse. CASE REPORT We report the case of a 71-year-old man with a traumatic inferior shoulder dislocation due to a fall. The patient had a medical history of stroke, and thus had a daily intake of 10 mg Warfarin. Previously, he had reported 2 anterior shoulder dislocations. The shoulder reduction was conducted under general anaesthesia after reduction with intravenous morphine sedation. Six hours after reduction, the patient showed signs of hemodynamic instability and a CT scan with contrast showed a suspected axillary artery rupture with a large hematoma in the right axilla. The artery rupture was confirmed with an arteriogram. The patient was successfully treated with an endovascular stent. After 3 months, the patient had normal neurovascular status in the right upper extremity and was continuing rehabilitation of the shoulder. CONCLUSIONS This case emphasizes the importance of proper recognition and awareness of artery injury after inferior shoulder dislocation. The symptoms of artery rupture after inferior shoulder dislocation can be immediate or have a late onset. The diagnostic modalities of CT scan with contrast or arteriogram should be performed with a low threshold of suspicion after reduction. With symptoms such as enlarging hematoma in the axilla, diminished radial and ulnar pulse, sudden pain from the axilla, or signs of hemodynamic instability after reduction, diagnostic modalities should be considered.

Rationale: Subchorionic Hematoma, often referred to as Bruce hematoma, can lead to serious obstetric complications such as intrauterine growth restriction and fetal death, as well as early and late pregnancy miscarriage, placental abruption, and premature rupture of membranes, posing great harm to both mother and fetus., Patient Concerns: At present, Western medical treatments have not shown satisfactory results, necessitating the discovery of more effective clinical treatment methods., Diagnoses: Threatened miscarriage, Subchorionic hematoma, Iron deficiency anemia (mild)., Interventions: Sanji Peiyuan decoction combined with dydrogesterone., Outcomes: Following 17 days of treatment with Sanji Peiyuan decoction and oral dydrogesterone tablets, the hematoma was no longer detectable by ultrasound. The patient experienced no symptoms such as abdominal pain, bloating, or vaginal bleeding. She successfully gave birth around her due date, with both the mother and child in good health., Lessons: The combination of Sanji Peiyuan decoction and oral dydrogesterone tablets shows promising clinical efficacy in treating Massive Subchorionic Hematomas. This method merits further clinical research., Competing Interests: The authors have no conflicts of interest to disclose., (Copyright © 2023 the Author(s). Published by Wolters Kluwer Health, Inc.)
