Background: Traumatic hemothorax (HTX) is often managed with tube thoracostomy (TT); however, TT carries a high complication rate. In 2017, a guideline was implemented at our Level I trauma center to observe traumatic HTX 300 mL or less in patients who are hemodynamically stable. We hypothesized that this guideline would decrease TT placement without increasing observation failure rates., Study Design: This was a single-center retrospective review of all adult patients admitted with an HTX on CT before (2015 to 2016) and after (2018 to 2019) the guideline implementation. Exclusion criteria were TT placement before CT scan, absence of CT scan, death within 5 days of admission, and a concurrent pneumothorax more than 20 mm. HTX volume was calculated using CT scan images and Mergo's formula: V = d2 × L (where V is the volume, d is the depth, and L is the length). The primary outcome was observation failure, defined as the need for TT, video-assisted thoracoscopic surgery, thoracotomy after repeat imaging or worsening of symptoms, and pulmonary morbidity., Results: A total of 357 patients met inclusion criteria, of whom 210 were admitted after guideline implementation. No significant differences in baseline demographics, comorbidities, or injury characteristics across both cohorts were observed. The postimplementation cohort had a significant increase in observation rate (75% vs 59%) and a decrease in TT placement (42% vs 57%). The postimplementation group had a statistically significant shorter hospital (6 vs 8 days) and ICU (2 vs 3 days) length of stay. No significant differences in observation failure, pulmonary complications, 30-day readmission, or 30-day mortality were observed across both cohorts., Conclusions: The implementation of the 300-mL guideline led to a decrease in TT placement without increasing observation failure or complication rates., (Copyright © 2024 by the American College of Surgeons.

Background: Retained hemothorax (rHTX) requiring intervention occurs in up to 20% of patients who undergo chest tube (TT) placement for a hemothorax (HTX). Thoracic irrigation at the time of TT placement decreases the need for secondary intervention in this patient group but those findings are limited because of the single-center design. A multicenter study was conducted to evaluate the effectiveness of thoracic irrigation., Methods: A multicenter, prospective, observational study was conducted between June 2018 and July 2023. Eleven sites contributed patients. Patients were included if they had a TT placed for a HTX and were excluded if: younger than 18 years, TT for pneumothorax, thoracotomy or video-assisted thoracoscopic surgery performed within 6 hours of TT, TT >24 hours after injury, TT removed <24 hours, or death within 48 hours. Thoracic irrigation was performed at the discretion of the attending. Each hemithorax was considered separately if bilateral HTX. The primary outcome was secondary intervention for HTX-related complications (rHTX, effusion, or empyema). Secondary intervention was defined as: TT placement, instillation of thrombolytics, video-assisted thoracoscopic surgery, or thoracotomy. Irrigated and nonirrigated hemithoraces were compared using a propensity weighted analysis with age, sex, mechanism of injury, Abbreviated Injury Scale chest, and TT size as predictors., Results: Four hundred ninety-three patients with 462 treated hemothoraces were included, 123 (25%) had thoracic irrigation at TT placement. There were no significant demographic differences between the cohorts. Fifty-seven secondary interventions were performed, 10 (8%) and 47 (13%) in the irrigated and non-irrigated groups, respectively ( p = 0.015). Propensity weighted analysis demonstrated a reduction in secondary interventions in the irrigated cohort (odds ratio, 0.56 (0.34-0.85); p = 0.005)., Conclusion: This Western Trauma Association multicenter study demonstrates a benefit of thoracic irrigation at the time of TT placement for a HTX. Thoracic irrigation reduces the odds of a secondary intervention for rHTX-related complications by 44%., Level of Evidence: Therapeutic/Care Management; Level II., (Copyright © 2024 Wolters Kluwer Health, Inc.

Objective: Although ultrasound can be considered an assistant method, successful placement of a central venous catheter (CVC) in infants is still challenging. The incidence of CVC placement-related complications is still high. Therefore, this systematic review aimed to synthesize evidence to assess the effects of ultrasound-guided CVC placement on adverse outcomes in infants and neonates aged <12 months., Methods: PubMed, Ovid, EMBASE, and the Cochrane Library were searched to identify potentially relevant studies. The main outcome was the incidence of adverse events, which included inadvertent arterial puncture, hematoma, pneumothorax and hemothorax, catheter kinking, threading, and malpositioning problems, venous thrombosis, catheter-related infection, phlebitis, and cardiac tamponade., Results: Eleven studies involving 2097 patients were included in the final analysis. The odds of inadvertent arterial puncture, and catheter kinking, threading, and malpositioning problems were lower in the ultrasound group than in the control group. No significant difference was detected in the incidence of hematoma or venous thrombosis between the control and ultrasound groups. Other complications, such as pneumothorax, hemothorax, phlebitis, and cardiac tamponade, rarely occurred., Conclusion: Ultrasound-guided CVC placement can improve the safety of punctures in neonates and infants. CVC punctures should be guided in real-time by ultrasound., Competing Interests: Declaration of conflicting interestThe authors declare that there is no conflict of interest.

Background: Traumatic hemothorax (HTX) is common, and while it is recommended to drain it with a tube thoracostomy, there is no consensus on the optimal catheter size. We performed a systematic review to test the hypothesis that small bore tube thoracostomy (SBTT) (≤14 F) is as effective as large-bore tube thoracostomy (LBTT) (≥20F) for the treatment of HTX., Methods: Pubmed, EMBASE, Scopus, and Cochrane review were searched from inception to November 2022 for randomized controlled trials or cohort studies that included adult trauma patients with HTX who received a tube thoracostomy. Data was extracted and Critical Appraisal Skills Program checklists were used for study appraisal. The primary outcome was failure rate, defined as incompletely drained or retained HTX requiring a second intervention. Cumulative analysis was performed with χ 2 test for dichotomous variables and an unpaired t-test for continuous variables. Meta-analysis was performed using a random effects model., Results: There were 2,008 articles screened, of which nine were included in the analysis. The studies included 1,847 patients (714 SBTT and 1,233 LBTT). The mean age of patients was 46 years, 75% were male, average ISS was 20, and 81% had blunt trauma. Failure rate was not significantly different between SBTT (17.8%) and LBTT (21.5%) ( p = 0.166). Additionally, there were no significant differences between SBTT vs. LBTT in mortality (2.9% vs. 6.1%, p = 0.062) or complication rate (12.3% vs. 12.5%, p = 0.941), however SBTT had significantly higher initial drainage volumes (753 vs. 398 mL, p < 0.001) and fewer tube days (4.3 vs. 6.2, p < 0.001). There are several limitations. Some studies did not report all the outcomes of interest, and many of the studies are subject to selection bias., Conclusion: SBTT may be as effective as LBTT for the treatment of traumatic HTX., Level of Evidence: Systematic Review/Meta-Analysis; Level IV., (Copyright © 2024 Wolters Kluwer Health, Inc.

Background: Unlike large hemothoraces (HTX), small HTX after blunt trauma may be observed without drainage. We aimed to study if there were risk factors that would predict the need for intervention in initially observed small HTX., Methods: A retrospective review of patients with blunt traumatic HTX from 2016 to 2022 was performed. Patients with small HTX (pleural fluid volume <400 mL on admission chest computerized tomography [CT]) were included. Patients were considered as being "initially observed" if there was no intervention for the HTX within 48 hours after admission. Primary outcome was any HTX-related intervention (open, thoracoscopic or percutaneous procedures) occurring after 48 hours and up to 6 months after injury. Univariable and multivariable statistical analyses were employed. A P -value of <.05 was considered significant., Results: Of 335 patients with HTX, 188 (59.6%) met inclusion criteria. Median (interquartile range) HTX volume was 90 (36-134) ml. One hundred and twenty-seven (68%) were initially observed. Of these, 31 (24%) had the primary outcome. These patients had a larger HTX volume (median, 129 vs 68 mL, P = .0001), and number of rib fractures (median, 7 vs 4, P = .0002) compared to those without the primary outcome. Chest-related readmission occurred in 8 (6%) with a median of 20 days from injury. Of these, 7 required an HTX-related intervention. Logistic regression analysis found that both the number of rib fractures and HTX volume independently predicted the primary outcome., Conclusion: For small HTX initially observed, number of rib fractures and initial volume predicted delayed HTX-related intervention., 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: Video-assisted thoracoscopic surgery (VATS) is a practical resource in the management of traumatic hemothorax. However, it carries inherent risks and should be mobilized cost-effectively. In this study, we investigated the ideal VATS timing using cost analysis., Methods: 617 cases of unilateral traumatic hemothorax from 2012 to 2022 were identified in our trauma database. We extracted encounter cost, length of stay (LOS), and operative cost information. Using Kruskal-Walli's test, we compared the cost and LOS for patients who underwent VATS or continued nonoperative management in the first 7 days of admission. Additionally, we computed the daily proportion of patients initially managed nonoperatively but ultimately underwent VATS. P -values <.05 were considered significant., Results: The median encounter cost of cases managed operatively before hospital day 4 (HD4) was higher than those managed nonoperatively. This difference was $63k on HD2 ( P -value .07) and was statistically significant for HD3 (difference of $65k, P -value .02). The median LOS with operational management on HD2 and 3 was 7 and 6 respectively vs median LOS of 2 and 3 with nonoperative management on those days ( P -value <.001, .01 respectively). The proportion of patients who failed nonoperative management did not change from baseline until HD4 (23% (95% CI 19.7, 26.3) vs 33.9% (95% CI 28.3, 39.6), P -value <.001)., Discussion: Early mobilization of VATS before hospital day 4 increases the overall hospital cost without offering any length of stay benefit. Continuing nonoperative management longer than 4 days is associated with a high failure rate and a costlier operation., 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.

Bleeding within the pleural space may result in persistent clot formation called retained hemothorax (RH). RH is prone to organization, which compromises effective drainage, leading to lung restriction and dyspnea. Intrapleural fibrinolytic therapy is used to clear the persistent organizing clot in lieu of surgery, but fibrinolysin selection, delivery strategies, and dosing have yet to be identified. We used a recently established rabbit model of RH to test whether intrapleural delivery of single-chain urokinase (scuPA) can most effectively clear RH. scuPA, or single-chain tissue plasminogen activator (sctPA), was delivered via thoracostomy tube on day 7 as either one or two doses 8 h apart. Pleural clot dissolution was assessed using transthoracic ultrasonography, chest computed tomography, two-dimensional and clot displacement measurements, and gross analysis. Two doses of scuPA (1 mg/kg) were more effective than a bolus dose of 2 mg/kg in resolving RH and facilitating drainage of pleural fluids (PF). Red blood cell counts in the PF of scuPA, or sctPA-treated rabbits were comparable, and no gross intrapleural hemorrhage was observed. Both fibrinolysins were equally effective in clearing clots and promoting pleural drainage. Biomarkers of inflammation and organization were likewise comparable in PF from both groups. The findings suggest that single-agent therapy may be effective in clearing RH; however, the clinical advantage of intrapleural scuPA remains to be established by future clinical trials.

Background: The objective of this study was to describe the causes of haemothorax in cats, patient presentation and outcome., Methods: This was a retrospective study based in a university teaching hospital. The electronic case records of cats presenting with a haemothorax between January 2005 and January 2023 were searched. Cases were categorised into 'trauma', 'neoplasia', 'coagulopathy' or 'other'. Signalment, physical examination, clinical pathology findings, concurrent injuries and diagnostic imaging findings were recorded. The median hospitalisation time was calculated, and survival to discharge was noted., Results: Twenty-five cats were eligible for inclusion. Twenty cases of haemothorax were traumatic in origin, two were neoplastic, two were 'other' and one was coagulopathic. Increased respiratory rate (n = 22) and effort (n = 20) were common, and most patients were anaemic at presentation (n = 16). Common concurrent injuries included pulmonary contusions (n = 15) and pneumothorax (n = 11). The median hospitalisation time for the trauma cats was 5 days (range 1‒15). Overall, 83.3% of the cases survived to discharge., Limitations: The limitations of this study are related to its retrospective nature and the relatively small number of cats in the study population., Conclusion: Haemothorax requiring a thoracocentesis in cats is rare, with trauma being the most likely cause. These patients tend to have concurrent injuries and require ongoing hospitalisation. Owners can be advised that the short-term outcome is generally favourable., (© 2024 The Author(s).

Background: Oral anticoagulation is becoming more common with the aging population, which raises concern for the risk of invasive procedures that can cause bleeding, such as chest tube placement (thoracostomy). With the increase in CT imaging, more pneumothoraces and hemothoraces are being identified. The relative risk of thoracostomy in the presence of anticoagulation is not well-established. The objective of this study was to determine whether pre-injury anticoagulation affects the relative risk of tube thoracostomy following significant chest trauma., Methods: This retrospective cohort study used data from the 2019 American College of Surgeons-Trauma Quality Program (ACS-TQP) database using R version 4.2.2. Data from the database was filtered based on inclusion and exclusion criteria. Outcomes were then assessed with the population of interest. Demographics, vitals, comorbidities, and injury parameters were also collected for each patient. This study included all adult patients (≥18 years) presenting with traumatic hemothorax, pneumothorax, or hemopneumothorax. Patients with missing data in demographics, vitals, comorbidities, injury parameters, or outcomes, as well as those with no signs of life upon arrival, were excluded from the study. Patients were stratified into groups based on whether they had pre-injury anticoagulation and whether they had a chest tube placed in the hospital. The primary outcome was mortality, and the secondary outcome was hospital length of stay (LOS). Logistic and standard regressions were used by a statistician to control for age, sex, and Injury Severity Score (ISS)., Results: Our study population included 72,385 patients (4250 with pre-injury anticoagulation and 68,135 without pre-injury anticoagulation). Pre-injury anticoagulation and thoracostomy were each independently associated with increased mortality and LOS. However, there was a non-significant interaction term between pre-injury anticoagulation and thoracostomy for both outcomes, indicating that their combined effects on mortality and LOS did not differ significantly from the sum of their individual effects., Conclusion: This study suggests that both pre-injury anticoagulation and thoracostomy are risk factors for mortality and increased LOS in adult patients presenting with hemothorax, pneumothorax, or hemopneumothorax, but they do not interact with each other. We recommend further study of this phenomenon to potentially improve clinical guidelines., Level of Evidence: Therapeutic, Level III., Competing Interests: Declaration of competing interest None., (Copyright © 2024 Elsevier Inc.

Background: Penetrating thoracic injuries have a significant risk of morbi-mortality. Despite the advancements in damage control methods, a subset of patients with severe pulmonary vascular lesions and bronchial injuries persists. In some of these cases, post-traumatic pneumonectomy is required, and perioperative extracorporeal membrane oxygenation (ECMO) support may be required due to right ventricular failure and respiratory failure., Case Description: A male was brought to the emergency department (ED) with a penetrating thoracic injury, presenting with massive right hemothorax and active bleeding that required ligation of the right pulmonary hilum to control the bleeding. Subsequently, he developed right ventricular dysfunction and ARDS, necessitating a dynamic hybrid ECMO configuration to support his condition and facilitate recovery., Conclusions: Penetrating thoracic injuries with severe pulmonary vascular lesions may need pneumonectomy to control bleeding. ECMO support reduces the associated mortality by decreasing the complications rate. A multidisciplinary team is essential to achieve good outcomes in severe compromised patients., (© 2024.

Rationale: Subclavian arterial injury due to blunt trauma is rare but can have devastating outcomes. Massive hemorrhage or limb ischemia might develop depending on the extent of damage, and open repair might be necessary to salvage the limb. However, life-saving treatments should be prioritized in critically unstable patients., Patient Concerns: A 21-year-old male patient who was transferred to our trauma center following a motorcycle accident. Abdominal and chest computed tomography (CT) revealed right renal injury and massive hemothorax with several rib fractures in the right chest., Diagnosis and Interventions: Right renal injury with multiple extravasations and right 8th intercostal arterial injury were detected during angiography. Emergent exploration with lateral thoracotomy was performed to manage right hemothorax. Pulsating bleeding from the thoracic roof observed in the operative field suggested a subclavian arterial injury. The unstable vital signs did not recover despite massive transfusion, and his right arm had already stiffened. Therefore, endovascular approach was adopted and the second portion of the right subclavian artery was embolized using microcoils and thrombin., Outcomes: Postoperative intensive care unit management performed to resuscitate patient from multiorgan failure included continuous renal replacement therapy (CRRT). After confirming the demarcation lines, transhumeral amputation of the right arm was performed on admission day 12. The patient recovered from multiorgan failure for more than 3 weeks after the accident; however, the patient survived., Lessons: Limb salvage, albeit critical for quality of life, is not possible in some cases where life-saving measures require its sacrifice. In these cases, quick decision-making by the surgeon is paramount for patient survival. As illustrated in this case, endovascular approaches should be considered less invasive measures to save the patient's life., Competing Interests: The authors have no funding and conflicts of interest to disclose., (Copyright © 2024 the Author(s).

Purpose: Post-operative pain after video-assisted thoracoscopic surgery is often treated using thoracic epidural analgesics or thoracic paravertebral analgesics. This article describes a case where a thoracic disc herniation is treated with a thoracoscopic microdiscectomy with post-operative thoracic epidural analgesics. The patient developed a bupivacaine pleural effusion which mimicked a hemothorax on computed tomography (CT)., Methods: The presence of bupivacaine in the pleural effusion was confirmed using a high performance liquid chromatography method., Results: The patient underwent a re-exploration to relieve the pleural effusion. The patient showed a long-term recovery similar to what can be expected from an uncomplicated thoracoscopic microdiscectomy., Conclusion: A pleural effusion may occur when thoracic epidural analgesics are used in patents with a corridor between the pleural cavity and epidural space., (© 2024.

Purpose: The aim of this case report is to report that delayed hemothorax is possible after anterior vertebral body tethering (aVBT) and to illustrate the course of treatment., Methods: We present a 15-year-old boy with adolescent idiopathic scoliosis who underwent an anterior thoracoscopic assisted vertebral body tethering who developed a massive right-sided hemothorax 12 days post-operatively. A chest tube was placed to drain the hemothorax and later required embolectomy with tissue plasminogen activator (TPA) to drain the retained hemothorax., Results: At 1 month follow up post discharge the patient was asymptomatic, and radiograph did not demonstrate evidence of residual hemothorax and scoliosis. We have followed this patient for 5 years postoperative and he continues to do well clinically and radiographically., Conclusions: Pulmonary complications are a known drawback of anterior thoracoscopic spinal instrumentation. Delayed hemothorax is possible after aVBT. In the case of a retained hemothorax, chest tube treatment with TPA is a safe and effective method of embolectomy., (© 2024.

Introduction: Retained hemothorax (HTX) is a common complication following thoracic trauma. Small studies demonstrate the benefit of thoracic cavity irrigation at the time of tube thoracostomy (TT) for the prevention of retained HTX. We sought to assess the effectiveness of chest irrigation in preventing retained HTX leading to a secondary surgical intervention., Methods: We performed a single-center retrospective study from 2017 to 2021 at a Level I trauma center, comparing bedside thoracic cavity irrigation via TT versus no irrigation. Using the trauma registry, patients with traumatic HTX were identified. Exclusion criteria were TT placement at an outside hospital, no TT within 24 hours of admission, thoracotomy or video-assisted thoracoscopic surgery (VATS) prior to or within 6 hours after TT placement, VATS as part of rib fixation or diaphragmatic repair, and death within 96 hours of admission. Bivariate and multivariable analyses were conducted., Results: A total of 370 patients met the inclusion criteria, of whom 225 (61%) were irrigated. Patients who were irrigated were more likely to suffer a penetrating injury (41% vs. 30%, p = 0.03) and less likely to have a flail chest (10% vs. 21%, p = 0.01). On bivariate analysis, irrigation was associated with lower rates of VATS (6% vs. 19%, p < 0.001) and retained HTX (10% vs. 21%, p < 0.001). The irrigated cohort had a shorter TT duration (4 vs. 6 days, p < 0.001) and hospital length of stay (7 vs. 9 days, p = 0.04). On multivariable analysis, thoracic cavity irrigation had lower odds of VATS (adjusted odds ratio, 0.37; 95% confidence interval [CI], 0.30-0.54), retained HTX (adjusted odds ratio, 0.42; 95% CI, 0.25-0.74), and a shorter TT duration ( β = -1.58; 95% CI, -2.52 to -0.75)., Conclusion: Our 5-year experience with thoracic irrigation confirms findings from smaller studies that irrigation prevents retained HTX and decreases the need for surgical intervention., Level of Evidence: Therapeutic/Care Management; Level III., (Copyright © 2024 Wolters Kluwer Health, Inc.

Introduction: Screening for pneumothorax (PTX) is standard practice after thoracostomy tube removal, with postpull CXR being the gold standard. However, studies have shown that point-of-care thoracic ultrasound (POCTUS) is effective at detecting PTX and may represent a viable alternative. This study aims to evaluate the safety and efficacy of POCTUS for evaluation of clinically significant postpull PTX compared with chest x-ray (CXR)., Methods: We performed a prospective, cohort study at a Level 1 trauma center between April and December 2022 comparing the ability of POCTUS to detect clinically significant postpull PTX compared with CXR. Patients with thoracostomy tube placed for PTX, hemothorax, or hemopneumothorax were included. Clinically insignificant PTX was defined as a small residual or apical PTX without associated respiratory symptoms or need for thoracostomy tube replacement while clinically significant PTX were moderate to large or associated with physiologic change., Results: We included 82 patients, the most common etiology was blunt trauma (n = 57), and the indications for thoracostomy tube placement were: PTX (n = 38), hemothorax (n = 15), and hemopneumothorax (n = 14). One patient required thoracostomy tube replacement for recurrent PTX identified by both ultrasound and X-ray. Thoracic ultrasound had a sensitivity of 100%, specificity of 95%, positive predictive value of 60%, and negative predictive value of 100% for the detection of clinically significant postpull PTX., Conclusions: The use of POCTUS for the detection of clinically significant PTX after thoracostomy tube removal is a safe and effective alternative to standard CXR. This echoes similar studies and emphasizes the need for further investigation in a multicenter study., (Published by Elsevier Inc.)

Background: Late hemothorax is a rare complication of blunt chest trauma. The longest reported time interval between the traumatic event and the development of hemothorax is 44 days., Case Presentation: An elderly patient with right-sided rib fractures from chest trauma, managed initially with closed thoracostomy, presented with a delayed hemothorax that occurred 60 days after initial management, necessitating conservative and then surgical intervention due to the patient's frail condition and associated complications., Conclusions: This case emphasizes the clinical challenge and significance of delayed hemothorax in chest trauma, highlighting the need for vigilance and potential surgical correction in complex presentations, especially in the elderly., (© 2024.

Background: Hemorrhage is the most common major complication after liver biopsy. Hemothorax is one type of bleeding and is very rare and dangerous. Several cases of hemothorax subsequent to liver biopsy have been documented, primarily attributed to injury of the intercostal artery or inferior phrenic artery and a few resulting from lung tissue damage; however, no previous case report of hemothorax caused by injury of musculophrenic artery after liver biopsy has been reported., Case Presentation: A 45-year-old native Chinese woman diagnosed with primary biliary cirrhosis due to long-term redness in urination and abnormal blood test indicators was admitted to our hospital for an ultrasound-guided liver biopsy to clarify pathological characteristics and disease staging. A total of 2 hours after surgery, the patient complained of discomfort in the right chest and abdomen. Ultrasound revealed an effusion in the right thorax and hemothorax was strongly suspected. The patient was immediately referred to the interventional department for digital subtraction angiography. Super-selective angiography of the right internal thoracic artery was performed which revealed significant contrast medium extravasation from the right musculophrenic artery, the terminal branch of the internal thoracic artery. Embolization was performed successfully. The vital signs of the patient were stabilized after the transarterial embolization and supportive treatment., Conclusion: This case draws attention to the musculophrenic artery as a potential source of hemorrhage after percutaneous liver biopsy., (© 2024.

As one of a major public health issue in China, the number of new cases and deaths of malignant tumors has been climbing year by year. Implantable venous access port (IVAP) is used as a safe infusion route in the treatment of malignant tumor patients such as infusion of antitumor drugs and intravenous nutrition. With the widespread application of ultrasound-guided Sedinger puncture techniques and intracardiac electrocardiogram positioning technology, IVAP in the upper arm has been recognized by the majority of medical personnel and cancer patients due to its advantages of hiding scars and completely avoiding the risk of hemothorax and pneumothorax. In order to standardize the clinical application of IVAP via the upper arm approach in cancer patients, improve the success rate of implantation, reduce complications and improve patient satisfaction, the Breast Cancer Expert Committee of the National Cancer Quality Control Center consulted guidelines and the latest evidence-based evidences and established the expert consensus on the whole-course management of implantable venous access port in the upper arm of cancer patients through literature research and expert discussions, in order to provide reference for the standard application of IVAP in the upper arm. The consensus mainly introduces the indications, contraindications, preoperative evaluation, implantation site, operation procedure, utilization and maintenance, complications and management, medical staff training and patient education of IVAP in the upper arm, in order to provide reference for clinical staff.

Background: Pulmonary arteriovenous malformation (PAVM), also known as pulmonary arteriovenous fistula, is a rare vascular developmental anomaly. Most cases of PAVM are associated with hereditary hemorrhagic telangiectasia (HHT). Hemothorax associated with PAVM is even rarer, and management concerning this complication still challenges., Case Presentation: A 55-year-old man with sudden onset of dyspnea and chest pain was admitted to our hospital. He had a medical history of epistaxis, intraperitoneal germ cell tumor and PAVM. Chest unenhanced CT revealed the left-sided pleural effusion together with partial passive atelectasis and gradual increase at the interval of six days. Diagnostic thoracocentesis further revealed hemorrhagic effusion. CT angiography (CTA) showed tortuously dilated lumen of the left lower pulmonary artery and PAVM with the formation of aneurysm. Due to his family's refusal of surgery, the patient underwent transcatheter embolization therapy. However, the left pleural effusion did not significantly reduce and there was a slow drop in hemoglobin value even after interventional treatment, indicating the possibility of ongoing active bleeding. Eventually, the patient received lobectomy of the left lower lobe with a satisfactory outcome., Conclusions: Massive hemothorax resulting from PAVM rupture into the pleural space can lead to fatal outcomes. CTA can accurately diagnose this pathologic condition. Transcatheter embolization is frequently used in the treatment of PAVM, but it may be challenging to achieve the desirable effect in patients with hemothorax. Combined with our case and literature review, direct radical surgery can lead to a successful outcome when PAVM complicated with hemothorax and a large diameter of the draining vein., (© 2024.

Objective: The mini-open lateral retropleural (MO-LRP) approach is an effective option for surgically treating thoracic disc herniations, but the approach raises concerns for pneumothorax (PTX). However, chest tube placement causes insertion site tenderness, necessitates consultation services, increases radiation exposure (requires multiple radiographs), delays the progression of care, and increases narcotic requirements. This study examined the incidence of radiographic and clinically significant PTX and hemothorax (HTX) after the MO-LRP approach, without the placement of a prophylactic chest tube, for thoracic disc herniation., Methods: This study was a single-institution retrospective evaluation of consecutive cases from 2017 to 2022. Electronic medical records were reviewed, including postoperative chest radiographs, radiology and operative reports, and postoperative notes. The presence of PTX or HTX was determined on chest radiographs obtained in all patients immediately after surgery, with interval radiographs if either was present. The size was categorized as large (≥ 3 cm) or small (< 3 cm) based on guidelines of the American College of Chest Physicians. PTX or HTX was considered clinically significant if it required intervention., Results: Thirty patients underwent thoracic discectomy via the MO-LRP approach. All patients were included. Twenty patients were men (67%), and 10 (33%) were women. The patients ranged in age from 25 to 74 years. The most commonly treated level was T11-12 (n = 11, 37%). Intraoperative violation of parietal pleura occurred in 5 patients (17%). No patient had prophylactic chest tube placement. Fifteen patients (50%) had PTX on postoperative chest radiographs; 2 patients had large PTXs, and 13 had small PTXs. Both patients with large PTXs had expansion on repeat radiographs and were treated with chest tube insertion. Of the 13 patients with a small PTX, 1 required 100% oxygen using a nonrebreather mask; the remainder were asymptomatic. One patient, who had no abnormal findings on the immediate postoperative chest radiograph, developed an incidental HTX on postoperative day 6 and was treated with chest tube insertion. Thus, 3 patients (10%) required a chest tube: 2 for expanding PTX and 1 for delayed HTX., Conclusions: Most patients who undergo thoracic discectomy via the MO-LRP approach do not develop clinically significant PTX or HTX. PTX and HTX in this patient population should be treated with a chest tube only when there are postoperative clinical and radiographic indications.

Background: The standard for managing traumatic pneumothorax (PTX), hemothorax (HTX), and hemopneumothorax (HPTX) has historically been large-bore (LB) chest tubes (>20-Fr). Previous studies have shown equal efficacy of small-bore (SB) chest tubes (≤19-Fr) in draining PTX and HTX/HPTX. This study aimed to evaluate provider practice patterns, treatment efficacy, and complications related to the selection of chest tube sizes for patients with thoracic trauma., Methods: A retrospective chart review was performed on adult patients who underwent tube thoracostomy for traumatic PTX, HTX, or HPTX at a Level 1 Trauma Center from January 2016 to December 2021. Comparison was made between SB and LB thoracostomy tubes. The primary outcome was indication for chest tube placement based on injury pattern. Secondary outcomes included retained hemothorax, insertion-related complications, and duration of chest tube placement. Univariate and multivariate analyses were performed., Results: Three hundred and forty-one patients were included and 297 (87.1%) received LB tubes. No significant differences were found between the groups concerning tube failure and insertion-related complications. LB tubes were more frequently placed in patients with penetrating MOI, higher average ISS, and higher average thoracic AIS. Patients who received LB chest tubes experienced a higher incidence of retained HTX., Discussion: In patients with thoracic trauma, both SB and LB chest tubes may be used for treatment. SB tubes are typically placed in nonemergent situations, and there is apparent provider bias for LB tubes. A future randomized clinical trial is needed to provide additional data on the usage of SB tubes in emergent situations., 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: Early video-assisted thoracoscopic surgery (VATS) is the recommended treatment of choice for retained hemothorax (RH). A prospective single-center randomized control study was conducted to compare outcomes between VATS and thoracostomy tube (TT) reinsertion for patients with RH after penetrating trauma in a resource constrained unit. Our hypothesis was that patients with a RH receiving VATS instead of TT reinsertion would have a shorter hospital stay and lesser complications., Materials and Methods: From January 2014 to November 2019, stable patients with thoracic penetrating trauma complicated with retained hemothoraces were randomized to either VATS or TT reinsertion. The outcomes were length of hospital stay (LOS) and complications., Results: Out of the 77 patients assessed for eligibility, 65 patients were randomized and 62 analyzed: 30 in the VATS arm and 32 in the TT reinsertion arm. Demographics and mechanisms of injury were comparable between the two arms. Length of hospital stay was: preprocedure: VATS 6.8 (+/-2.8) days and TT 6.6 (+/- 2.4) days (p = 0.932) and postprocedure: VATS 5.1 (+/-2.3) days, TT 7.1 (+/-6.3) days (p = 0.459), total LOS VATS 12 (+/- 3.9) days, and TT 14.4 (+/-7) days (p = 0.224). The TT arm had 15 complications compared to the VATS arm of four (p = 0.004). There were two additional procedures in the VATS arm and 10 in the TT arm (p = 0.014)., Conclusion: VATS proved to be the better treatment modality for RH with fewer complications and less need of additional procedures, while the LOS between the two groups was not statistically different., (© 2024 The Authors.

A 74-year-old man who recently undergone a definitive pacemaker implantation with an apical septal active lead fixation presented to the emergency department because of a new-onset acute chest pain that began soon after cough episodes. Pacemaker interrogation reported an increased bipolar pacing threshold (3.25 V at 1 ms). Contrast-enhanced chest CT scan and percutaneous angiography revealed the sequential perforation of the right ventricular apex and the left internal mammary artery by the ventricular pacemaker lead. Successful percutaneous embolization of the LIMA, blood transfusion and thoracentesis were then performed, and the patient subsequently underwent a percutaneous ventricular lead extraction followed by re-implantation, with an uneventful follow-up after 2 years. This unique case report highlights a potential rare complication of the active fixation of the ventricular lead at the apical interventricular septum and should lead the clinicians to keep in mind right ventricular perforation, even without cardiac tamponade, in patients presenting for cardio-pulmonary symptoms soon after pacemaker implantation., (© 2023.

Objective: To describe an unusual case of spontaneous hemothorax resulting from thymic involution in a dog with suspected acquired bleeding dyscrasia associated with steroid-responsive meningitis-arteritis (SRMA)., Case Description: A 6-month-old spayed female Golden Retriever was referred due to the sudden onset of lethargy, fever (pyrexia), loss of appetite (anorexia), and moderate neck pain. These symptoms emerged six days after an ovariohysterectomy performed by the primary veterinarian. Upon admission, the patient exhibited pale mucous membranes, tachycardia (180 bpm), bilateral muffled heart sounds and tachypnea. Abdominal and thoracic point-of-care ultrasound (POCUS) were performed and revealed bilateral pleural effusion. Due to the patient's unstable condition, emergent thoracocentesis and transfusion of packed red blood cells was required. The initial work-up performed included a complete blood cell count (CBC), biochemistry profile, venous blood gas and coagulation panel (PT, APTT, fibrinogen). Pleural effusion analysis was compatible with hemothorax. Bloodwork was unremarkable including the initial coagulation panel. Further coagulation test was performed including buccal mucosal bleeding time, viscoelastic-based clot detection tests (TEG) and Von Willebrand factor antigen measurement. TEG revealed marked hyperfibrinolysis. Angiostrongylus vasorum and 4DX snap test were performed and yielded a negative result. Thoracic CT scan revealed the presence of a soft tissue-attenuating mass in the ventral mediastinum, thymic involution, and enlargement of the sternal and mediastinal lymph nodes. Therapy with tranexamic acid and corticosteroids at anti-inflammatory doses was initiated. Marked clinical improvement was observed within 24 hours, and after three days of hospitalization the patient was discharged. One month later, the dog was referred again for acute pyrexia, hyporexia, and neck pain which progressed to non-ambulatory tetraparesis. Neurological examination was compatible with C6-T2 lesion. MRI and cerebrospinal fluid analysis were performed and revealed a final diagnosis of steroid-responsive meningitis-arteritis (SRMA) with associated intramedullary hemorrhage. Corticosteroids were started again, and the patient showed a dramatic improvement over the next 24 hours. Three weeks after the diagnosis, the dog returned to a clinically normal state. The treatment was gradually tapered over the following months, guided by regular neurological and clinical examinations and CRP measurements, without any relapses., New or Unique Information: To the best of the author's knowledge, this is the first documented case of a dog experiencing spontaneous hemothorax as a result of thymic hemorrhage/involution which, in the absence of other identifiable diseases, was attributed to a hyperfibrinolytic state induced by a severe inflammatory disease such as SRMA., Competing Interests: Declaration of competing interest The authors declare that they have no conflict of interest., (Copyright © 2024.

Background: Intra-thoracic organ bleeding and chest wall injury following chest trauma can easily lead to life-threatening emergencies and a delay in treatment may lead to fatal outcomes. Interestingly, the optimal timing, indications, and surgical techniques have not been standardized., Method: We retrospectively analyzed 35 patients who underwent surgical treatment for chest trauma., Results: All patients with penetrating trauma (n=4) underwent emergency surgery for a hemothorax. There were no postoperative complications or hospital deaths. All patients with blunt trauma( n= 31) had multiple rib fractures;rib fixation was performed in 29 patients( 94%). Eight patients( 26%) had flail chest. The duration from injury to surgery averaged 7.5 days. The prognosis was generally favorable with no postoperative complications, but two patients died in the hospital due to multiple organ failure caused by high-energy trauma. Patients with flail chest or multiple organ injury had prolonged postoperative hospital stays., Conclusions: Patients who sustain chest trauma follow various clinical courses. Appropriate timing of surgical intervention at an early stage after injury can be life saving and hasten a functional recovery.

This report describes a very rare but life-threatening complication that occurred in a 43-year-old woman after an acupuncture (AC) for lumbago. The patient presented to the emergency department displaying symptoms indicative of shock. Physical examination revealed the absence of breath sounds on the right thoracic side, further investigations indicated the presence of a hemothorax. Emergency surgery was performed to evacuate the hemothorax and control bleeding from two intercostal veins. Although AC is often considered a gentle form of medicine, it is important to recognize that it can occasionally result in severe complications, especially when acupoints are used on the thorax.

Background: Our program uses a desensitization protocol that includes intraoperative therapeutic plasma exchange (iTPE) for crossmatch-positive lung transplants, which improves access to lung transplant for sensitized candidates while mitigating immunologic risk. Although we have reported excellent outcomes for sensitized patients with the use of this protocol, concern for perioperative bleeding appears to have hindered broader adoption of it at other programs. We conducted a retrospective cohort study to quantify the impact of iTPE on perioperative bleeding in lung transplantation., Methods: All first-time lung transplant recipients from 2014 to 2019 who received iTPE were compared to those who did not. Multivariable logistic regression was used to determine the association between iTPE and large-volume perioperative transfusion requirements (≥5 packed red blood cell units within 24 hours of transplant start), adjusted for disease type, transplant type, and extracorporeal membrane oxygenation or cardiopulmonary bypass use. The incidence of hemothorax (requiring reoperation within 7 days of lung transplant) and 30-day posttransplant mortality were compared between the 2 groups using chi-square test., Results: One hundred forty-two patients (16%) received iTPE, and 755 patients (84%) did not. The mean number of perioperative pRBC transfusions was 4.2 among patients who received iTPE and 2.9 among patients who did not. iTPE was associated with increased odds of requiring large-volume perioperative transfusion (odds ratio 1.9; 95% confidence interval: 1.2-2.9, p-value = 0.007) but was not associated with an increased incidence of hemothorax (5% in both groups, p = 0.99) or 30-day posttransplant mortality (3.5% among patients who received iTPE vs 2.1% among patients who did not, p = 0.31)., Conclusions: This study demonstrates that the use of iTPE in lung transplantation may increase perioperative bleeding but not to a degree that impacts important posttransplant outcomes., (Copyright © 2023 International Society for the Heart and Lung Transplantation.

A woman in her 80s experienced a life-threatening complication of pacemaker implant consisting of subacute right ventricular lead perforation causing iatrogenic injury to an intercostal artery, resulting in a large haemothorax. A CT scan confirmed active bleeding from the fourth intercostal artery. The patient underwent cardiothoracic surgery via a median sternotomy approach, during which the source of the bleeding was sealed, a new epicardial lead was positioned, and the original lead was extracted. This case emphasises the potentially severe consequences of pacemaker lead perforation and secondary injury to adjacent structures. It underscores the importance of early recognition and timely intervention, preferably in a tertiary specialist unit equipped for cardiothoracic surgery and confirms the value of pacemaker interrogation and CT scans for diagnosis., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2024.

Objectives: Although rib fractures are a risk factor, not all rib fracture patients will develop delayed hemothorax. This study aimed to evaluate risk factors which can identify rib fracture patients in the emergency department who may develop delayed hemothorax., Methods: Adult patients seen in the emergency room between January 2016 and February 2021 with rib fractures caused by blunt chest trauma were included in this retrospective observational study. Patients who underwent chest tube insertion within 2 days and those without follow-up chest radiographs within 2-30 days were excluded. We used a stepwise backward-elimination multivariable logistic regression model for analysis., Results: A total of 202 patients were included in this study. The number of total (P < 0.001), lateral (P = 0.019), and displaced (P < 0.001) rib fractures were significantly associated with delayed hemothorax. Lung contusions (P = 0.002), and initial minimal hemothorax (P < 0.001) and pneumothorax (P < 0.001) were more frequently associated with delayed hemothorax. Age (adjusted odds ratio (aOR) 1.03, 95% confidence interval (CI) 1.00-1.06, P = 0.022), mechanical ventilator use (aOR 9.67, 95% CI 1.01-92.75, P = 0.049), initial hemothorax (aOR 2.21, 95% CI 1.05-4.65, P = 0.037) and pneumothorax (aOR 2.99, 95% CI 1.36-6.54, P = 0.006), and displaced rib fractures (aOR 3.51, 95% CI 1.64-7.53, P = 0.001) were independently associated with delayed hemothorax., Conclusions: Age, mechanical ventilation, initial hemo- or pneumothorax, and displaced rib fractures were risk factors for delayed hemothorax. Patients with these risk factors, and especially those with ≥2 displaced rib fractures, require close chest radiography follow-up of 2-30 days after the initial trauma., Competing Interests: Declaration of Competing Interest The authors have no conflicts of interest to declare., (Copyright © 2023 Elsevier Inc.

Background: On February 6, 2023, an earthquake in Türkiye caused massive destruction. Over 50.000 people are known to have lost their lives, and over 100.000 are known to have been maimed. In our study, we aimed to analyze the treatment process of 267 METHODS: The demographic characteristics, the time spent under the rubble, the duration of transfer to the hospital, and the treatment process of patients admitted to our hospital have been evaluated., Results: There are 125 (46.8%) men and 142 (53.2%) women in the study. The rate of thoracic trauma was 21.8%. Of all the patients, 15.7% (n=42) had pneumothorax, 18% (n=48) had contusion, 28.8% (n=77) had hemothorax, and 73% (n=195) had rib fractures. The mean time spent under the rubble was 17.6±26.5 h, the duration of transfer to the hospital was 138.5±113.6 h, and the hospitalization time was 93.8±152.3 h. The duration of hospitalization and transfer has been statistically longer for the patients who were under the rubble (85.4%) than for those who were not. (14.6%) (p=0.048). There is a statistically weak positive correlation between the time spent under the rubble and the time of transfer (p=0.048)., Conclusion: The state, the time spent under the rubble, and the presence of hemothorax and pneumothorax should be effectively evaluated in earthquake-induced thoracic traumas. Considering these criteria in the transfer of patients to the centers operating at full capacity in a short time will minimize morbidity and mortality.

Introduction: Current guidelines for retained hemothorax (rHTX) in trauma patients recommend video-assisted thoracic surgery (VATS) within 4 days. However, this recommendation is currently based upon evidence from small observational studies. The aim of this study is to further evaluate the association between timing of VATS and clinical outcomes in rHTX following trauma., Methods: Using the 2017-2019 Trauma Quality Improvement Program database, adult (≥15 years-old) trauma patients with rHTX who underwent evacuation of rHTX through VATS were included. Multivariable linear and logistic regression were used to evaluate the association between the timing of VATS and clinical outcomes. Postponing/delaying evacuation through VATS was defined in our analysis as performing the surgery 1 day later in time., Results: 793 patients were included. VATS was performed at a median 4.5 days (Interquartile range = 2.4, 8.4). A 1.17 day increase in hospital length of stay (P = <0.001), a 0.17 day increase in postoperative hospital length of stay (P = 0.007), a 0.48 day increase in ventilation days (P = <0.001), and a 0.66 day increase in intensive care unit length of stay (P = <0.001) was found for each day that VATS was delayed. Additionally, a 1.10 odds ratio for infectious complications (P = <0.001) and a 0.96 odds ratio for discharge to home (P = 0.006) was seen for each day VATS was delayed. There was no significant association between the timing of VATS failure of VATS (defined as requiring additional procedures such as a secondary VATS or progressed to thoracotomy after initial VATS) and mortality (P > 0.05)., Conclusions: While delaying VATS was statistically associated with increased hospital length of stay, and other secondary outcomes, the clinical significance of the increase in these variables were less dramatic compared to the results of other studies, thus tempering the urgency of evacuation. Additionally, there was no association found between the timing of VATS and mortality, discharge disposition, or the need for additional VATS and/or thoracotomy. Therefore, in the appropriate clinical context, the evacuation of rHTX through VATS can be delayed if clinically necessary, without an associated increase in mortality or the requirement for additional procedures., (Copyright © 2023 Elsevier Inc.

Retained hemothorax (RH) is a commonly encountered and potentially severe complication of intrapleural bleeding that can organize with lung restriction. Early surgical intervention and intrapleural fibrinolytic therapy have been advocated. However, the lack of a reliable, cost-effective model amenable to interventional testing has hampered our understanding of the role of pharmacological interventions in RH management. Here, we report the development of a new RH model in rabbits. RH was induced by sequential administration of up to three doses of recalcified citrated homologous rabbit donor blood plus thrombin via a chest tube. RH at 4, 7, and 10 days post-induction (RH4, RH7, and RH10, respectively) was characterized by clot retention, intrapleural organization, and increased pleural rind, similar to that of clinical RH. Clinical imaging techniques such as ultrasonography and computed tomography (CT) revealed the dynamic formation and resorption of intrapleural clots over time and the resulting lung restriction. RH7 and RH10 were evaluated in young (3 mo) animals of both sexes. The RH7 recapitulated the most clinically relevant RH attributes; therefore, we used this model further to evaluate the effect of age on RH development. Sanguineous pleural fluids (PFs) in the model were generally small and variably detected among different models. The rabbit model PFs exhibited a proinflammatory response reminiscent of human hemothorax PFs. Overall, RH7 results in the consistent formation of durable intrapleural clots, pleural adhesions, pleural thickening, and lung restriction. Protracted chest tube placement over 7 d was achieved, enabling direct intrapleural access for sampling and treatment. The model, particularly RH7, is amenable to testing new intrapleural pharmacologic interventions, including iterations of currently used empirically dosed agents or new candidates designed to safely and more effectively clear RH.

A woman in her 50s was transported to our hospital after experiencing a road traffic crash that led to a massive haemothorax and haemorrhagic shock due to a cervical vascular injury caused by the seat belt. Contrast-enhanced CT of the chest showed extravascular leakage of the contrast medium from the vicinity of the right subclavicular area and fluid accumulation in the thoracic cavity. The patient was intubated, and a thoracic drainage catheter was placed. She underwent angiography and embolisation of the right costocervical trunk, right thyrocervical trunk and right suprascapular artery using a gelatine sponge and 25% N -butylcyanoacrylate-Lipiodol. She was extubated on the second day after stabilisation of the respiratory and circulatory status. In cases where the bleeding vessel is known and an emergency thoracotomy can serve as a backup, embolisation by interventional radiology should be considered the initial treatment approach., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2023.

Background: Prior studies suggest similar efficacy between large-bore chest tube (CT) placement and small-bore pigtail catheter (PC) placement for the treatment of pleural space processes. This study examined reintervention rates of CT and PC in patients with pneumothorax, hemothorax, and pleural effusion., Methods: This retrospective study examined patients from September 2015 through December 2020. Patients were identified using ICD codes for pneumothorax, hemothorax, or pleural effusion. Use of a pigtail catheter (≤14Fr) or surgical chest tube (≥20Fr) was noted. The primary outcome was overall reintervention rate within 30 days of tube insertion. Patients who died with a pleural drainage catheter in place, unrelated to complications from chest tube placement, were excluded., Results: There were 1032 total patients in the study: 706 CT patients and 326 PC patients. The PC group was older with more comorbidities and more likely to have effusion as the indication for pleural drainage. Patients with PC were 2.35 times more likely to have the tube replaced or repositioned ( P < .0001), 1.77 times more likely to require any reintervention ( P = .001) and 2.09 times more likely to remain in the hospital >14 days ( P < .0001) compared to patients with CT., Conclusion: PCs have a significantly higher reintervention rate compared to CT for the treatment of pneumothorax, hemothorax, and pleural effusion. Although PC are believed to cause less pain and tissue trauma, they do not necessarily drain the pleural space as well as CT. Decisions on which method of draining the chest should be made on a case-by-case basis., 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: While the role of Extended Focused Assessment with Sonography in Trauma (eFAST) is well defined in the management of severe blunt trauma, its performance in injuries caused by stab wounds has been poorly assessed., Methods: Prospective single centre study which included all patients with stab wounds to the thorax or abdomen between December 2016 and December 2018. All patients underwent initial investigation with both eFAST and CT scan, except in cases of haemodynamic or respiratory instability, and in cases with a positive diagnosis by eFAST in which case surgery without CT scan was performed., Results: Of the 200 consecutive patients included, 14 unstable patients underwent surgery immediately after eFAST. In these 14 patients, 9 had cardiac tamponade identified by eFAST and all were confirmed by surgery. In the remaining 186 patients, the median time between eFAST and CT scan was 30 min (IQR 20-49 min). Test characteristics (including 95% CI) for eFAST compared with reference standard of CT scan for detecting pneumothorax were as follows: sensitivity 77% (54%-92%), specificity 93% (90%-97%), positive predictive value (PPV) 60% (49%-83%), negative predictive value (NPV) 97% (93%-99%). Test characteristics (including 95% CI) for eFAST compared with CT scan for detecting haemothorax were as follows: sensitivity 97% (74%-99%), specificity 96% (92%-98%), PPV 83% (63%-93%) and NPV 99% (96%-100%). Finally, test characteristics (including 95% CI) for eFAST compared with CT scan for detecting haemoperitoneum were as follows: sensitivity 75% (35%-97%), specificity 97% (93%-99%), PPV 55% (23%-83%) and NPV 99% (96%-99%)., Conclusions: In patients admitted with stab wounds to the torso, eFAST was not sensitive enough to diagnose pneumothorax and haemoperitoneum, but performed better in the detection of cardiac tamponade and haemothorax than the other injuries. More robust multicentre studies are needed to better define the role of eFAST in this specific population., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2023.

Purpose: To evaluate the safety and efficacy of transcatheter arterial embolization (TAE) in controlling hemodynamically unstable bleeding following a percutaneous transthoracic needle biopsy (PTNB)., Methods: A total of seven patients (four men and three women; mean age, 62 ± 12 years) who received TAE for post-PTNB bleeding between May 2007 and March 2022 were included. The observed types of bleeding were hemothorax (n = 3), hemoptysis (n = 2), and a combination of both (n = 2). In patients with active bleeding, the technical success of TAE was defined as superselective embolization of the target artery with no active bleeding visible on post-TAE angiography. Clinical success was defined as sustained cessation of bleeding without hemodynamic instability, requirement of repeat TAE, or the need for post-TAE hemostatic surgery during the initial admission. The metrics analyzed included technical and clinical success rates, complications, and 30-day mortality., Results: All seven patients achieved technical success, with a clinical success rate of 86% (6/7). Six patients were discharged alive, while one patient died of respiratory failure accompanied by hemothorax 19 days post-biopsy. The angiographic findings associated with bleeding were contrast media extravasation or pseudoaneurysm (n = 3) and vascular hypertrophy with tortuosity (n = 2). The implicated bleeding arteries included the intercostal artery (n = 2), bronchial artery (n = 2), and internal thoracic artery (n = 1). In two cases, no clear bleeding foci were identified; nonetheless, prophylactic embolization was performed on the right intercostal artery (n = 1) and right intercostobronchial trunk (n = 1). The embolic agents utilized included microcoils (n = 1), gelatin sponge particles (n = 2), polyvinyl alcohol (PVA) with gelatin sponge particles (n = 1), PVA with microcoils (n = 1), microcoils with gelatin sponge particles (n = 1), and microcoils with n-butyl-2-cyanoacrylate and gelatin sponge particles (n = 1). The 30-day mortality rate was 14% (1/7). No ischemic complications related to TAE were observed., Conclusion: The study suggests that TAE is safe and effective for controlling hemodynamically unstable bleeding following a PTNB.

We present a case of repeated child abuse causing left-sided hemothorax and cardiac tamponade on two separate occasions. A 14-year-old cerebral palsy male presented with left-sided hemothorax and multiple metallic foreign bodies in the chest wall managed by small limited incision, removal of the foreign bodies and chest tube. One week later, he came to our emergency department (ER) with multiple chest wall foreign bodies and tamponade managed by median sternotomy, removal of the foreign bodies, one of them was in the LAD. He had a smooth postoperative course and the case is under investigation., 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.

Pulmonary sarcomatoid carcinoma (PSC) is a rare and highly invasive malignant tumour. It has similar clinical manifestations and imaging features to ordinary lung cancer. This current case report describes a 65-year-old male patient who had a mass in the apicoposterior segment of the left upper lobe with haemoptysis. Imaging studies revealed a central parenchymal mass surrounded by areas of ground-glass opacity, strongly indicating the presence of a pulmonary malignancy. Intraoperatively, the tumour was discovered to have invaded the chest wall and exhibited a significant propensity for bleeding. Consequently, a left upper lobe resection accompanied by extensive pleural debridement were performed. Subsequent postoperative histopathological examination confirmed the diagnosis of PSC. Unfortunately, 1 month after the surgery, the patient presented with left-sided haemothorax. Despite employing various haemostatic interventions, the patient eventually succumbed to haemorrhagic shock. This study provides a treatment strategy reference for patients with PSC presenting as haemothorax., Competing Interests: Declaration of conflicting interestThe authors declare that there are no conflicts of interest.

Background: Traumatic hemothorax is common, and management failure leads to worse outcomes. We sought to determine predictive factors and understand the role of trauma center performance in hemothorax management failure., Methods: We prospectively examined initial hemothorax management (observation, pleural drainage, surgery) and failure requiring secondary intervention in 17 trauma centers. We defined hemothorax management failure requiring secondary intervention as thrombolytic administration, tube thoracostomy, image-guided drainage, or surgery after failure of the initial management strategy at the discretion of the treating trauma surgeon. Patient-level predictors of hemothorax management failure requiring secondary intervention were identified for 2 subgroups: initial observation and immediate pleural drainage. Trauma centers were divided into quartiles by hemothorax management failure requiring secondary intervention rate and hierarchical logistic regression quantified variation., Results: Of 995 hemothoraces in 967 patients, 186 (19%) developed hemothorax management failure requiring secondary intervention. The frequency of hemothorax management failure requiring secondary intervention increased from observation to pleural drainage to surgical intervention (12%, 22%, and 35%, respectively). The number of ribs fractured (odds ratio 1.12 per fracture; 95% confidence interval 1.00-1.26) and pulmonary contusion (odds ratio 2.25, 95% confidence interval 1.03-4.91) predicted hemothorax management failure requiring secondary intervention in the observation subgroup, whereas chest injury severity (odds ratio 1.58; 95% confidence interval 1.17-2.12) and initial hemothorax volume evacuated (odds ratio 1.10 per 100 mL; 95% confidence interval 1.05-1.16) predicted hemothorax management failure requiring secondary intervention after pleural drainage. After adjusting for patient characteristics in the logistic regression model for hemothorax management failure requiring secondary intervention, patients treated at high hemothorax management failure requiring secondary intervention trauma centers were 6 times more likely to undergo an intervention after initial hemothorax management failure than patients treated in low hemothorax management failure requiring secondary intervention trauma centers (odds ratio 6.18, 95% confidence interval 3.41-11.21)., Conclusion: Failure of initial management of traumatic hemothorax is common and highly variable across trauma centers. Assessing patient selection for a given management strategy and center-level practices represent opportunities to improve outcomes from traumatic hemothorax., (Copyright © 2023 Elsevier Inc.

Background: Haemothorax occurs in approximately 60% of all thoracic and polytrauma cases and is responsible for 15-30% of all trauma mortalities. Penetrating injuries to the thorax are a common presentation in South African hospitals. This study aims to audit the traumatic haemothoraces and their outcomes in regional hospitals in Durban, KwaZulu-Natal, South Africa., Methods: In this study, patient characteristics were grouped as either continuous or categorical variables. Continuous variables, such as age were summarised as means (with standard deviations) or medians (interquartile range [IQR]), as appropriate. Categorical variables such as sex were summarised as proportions. Fisher's exact test was used to compare proportions. All analyses were performed using the Statistical Package for Social Sciences., Results: A total of 118 patients were included comprising 110 (93%) males and eight (7%) females, with an average age of 29.7 years. Stab-chest was the most frequent mechanism of injury (76; 64.4%), followed by gunshot wound (GSW)- chest (27; 22.9%) and isolated blunt chest trauma (9; 7.6%). Other mechanisms of injury were stab-neck (3; 2.5%), stab-shoulder (2; 1.7%) and blunt chest trauma in the context of polytrauma (1; 0.8%). The most frequent type of injury was penetrating (108; 91.5%), with only 10 (8.5%) cases of blunt injury. This study found that there was a statistically significant association between patient age groups and type of injury., Conclusion: Haemothorax is a common sequela of chest trauma. Retained haemothorax (RH) results in worsened patient outcomes including increased hospital length of stay (LOS). This study points to the need for auditing of proper intercostal chest drain (ICD) positioning, which is crucial for the successful drainage of haemothorax., (Copyright© Authors.)

Introduction: Up to a quarter of all traumatic deaths are due to thoracic injuries. Current guidelines recommend consideration of evacuation of all hemothoraces with tube thoracostomy. The aim of our study was to determine the impact of pre-injury anticoagulation on outcomes of traumatic hemothorax patients., Materials and Methods: We performed a 4-year (2017 - 2020) analysis of the ACS-TQIP database. We included all adult trauma patients (age ≥18 years) presenting with hemothorax and no other severe injuries (other body regions <3). Patients with a history of bleeding disorders, chronic liver disease, or cancer were excluded from this study. Patients were stratified into two groups based on the history of preinjury anticoagulant use (AC, preinjury anticoagulant use: No-AC, no preinjury anticoagulant use). Propensity score matching (1:1) was done by adjusting for demographics, ED vitals, injury parameters, comorbidities, thromboprophylaxis type, and trauma center verification level. Outcome measures were interventions for hemothorax (chest tube, video-assisted thoracoscopic surgery [VATS]), reinterventions (chest tube > once), overall complications, hospital length of stay (LOS), and mortality., Results: A matched cohort of 6,962 patients (AC, 3,481; No-AC, 3,481) was analyzed. The median age was 75 years, and the median ISS was 10. The AC and No-AC groups were similar in terms of baseline characteristics. Compared to the No-AC group, AC group had higher rates of chest tube placement (46% vs 43%, p = 0.018), overall complications (8% vs 7%, p = 0.046), and longer hospital LOS (7[4-12] vs 6[3-10] days, p ≤ 0.001). Reintervention and mortality rates were similar between the groups (p>0.05)., Conclusion: The use of preinjury anticoagulants in hemothorax patients negatively impacts patient outcomes. Increased surveillance is required while dealing with hemothorax patients on pre-injury anticoagulants, and consideration should be given to earlier interventions for such patients., Competing Interests: Declaration of Competing Interest There are no identifiable conflicts of interest to report., (Copyright © 2023.

Thoracic aortic dissection is a life-threatening diagnosis, which should not be missed. We present a case in which a patient who presented to the emergency department with chest pain was assessed and referred for admission for treatment of pneumonia, due to misinterpretation of a chest radiograph finding. The patient was re-reviewed and subsequently underwent further investigation, which confirmed aortic dissection. She underwent emergency thoracic endovascular aortic graft repair with stent graft insertion. This case demonstrates haemothorax as an uncommon complication of aortic dissection., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2023.

Background Routine addition of an atrial lead during an implantable cardioverter-defibrillator (ICD) implantation for primary prevention of sudden cardiac death, in patients without pacing indications, was not shown beneficial in contemporary studies. We aimed to investigate the use and safety of single- versus dual-chamber ICD implantations in these patients. Methods and Results Using the National Inpatient Sample database, we identified patients with no pacing indications who underwent primary-prevention ICD implantation in the United States between 2015 and 2019. Sociodemographic and clinical characteristics, as well as in-hospital complications, were analyzed. Multivariable logistic regression was used to identify predictors of in-hospital complications. An estimated total of 15 940 patients, underwent ICD implantation for primary prevention of sudden cardiac death during the study period, 8860 (55.6%) received a dual-chamber ICD. The mean age was 64 years, and 66% were men. In-hospital complication rates in the dual-chamber ICD and single-chamber ICD group were 12.8% and 10.7%, respectively ( P <0.001), driven by increased rates of pneumothorax/hemothorax (4.6% versus 3.4%; P <0.001) and lead dislodgement (3.6% versus 2.3%; P <0.001) in the dual-chamber ICD group. Multivariable analyses confirmed atrial lead addition as an independent predictor for "any complications" (odds ratio [OR], 1.1 [95% CI, 1.0-1.2]), for pneumo/hemothorax (odds ratio, 1.1 [95% CI, 1.0-1.4]), and for lead dislodgement (odds ratio, 1.3 [95% CI, 1.1-1.6]). Conclusions Despite lack of evidence for clinical benefit, dual-chamber ICDs are implanted for primary prevention of sudden cardiac death in a majority of patients who do not have pacing indication. This practice is associated with increased risk of periprocedural complications. Avoidance of routine implantation of atrial leads will likely improve safety outcomes.

Introduction: A debate currently exists regarding the efficacy of pigtail catheters vs chest tubes in the management of thoracic trauma. This meta-analysis aims to compare the outcomes of pigtail catheters vs chest tubes in adult trauma patients with thoracic injuries., Methods: This systematic review and meta-analysis were conducted using PRISMA guidelines and registered with PROSPERO. PubMed, Google Scholar, Embase, Ebsco, and ProQuest electronic databases were queried for studies comparing the use of pigtail catheters vs chest tubes in adult trauma patients from database inception to August 15th, 2022. The primary outcome was the failure rate of drainage tubes, defined as requiring a second tube placement or VATS, unresolved pneumothorax, hemothorax, or hemopneumothorax requiring additional intervention. Secondary outcomes were initial drainage output, ICU-LOS, and ventilator days., Results: A total of 7 studies satisfied eligibility criteria and were assessed in the meta-analysis. The pigtail group had higher initial output volumes vs the chest tube group, with a mean difference of 114.7 mL [95% CI (70.6 mL, 158.8 mL)]. Patients in the chest tube group also had a higher risk of requiring VATS vs the pigtail group, with a relative risk of 2.77 [95% CI (1.50, 5.11)]., Conclusions: In trauma patients, pigtail catheters rather than chest tubes are associated with higher initial output volume, reduced risk of VATS, and shorter tube duration. Considering the similar rates of failure, ventilator days, and ICU length-of-stay, pigtail catheters should be considered in the management of traumatic thoracic injuries., Study Type: Systematic Review and meta-analysis.
