Introduction :HemosuccusPancreaticus is an extremely rare cause of Upper GI bleeding and is described as a haemorrhage from the ampulla of Vater passing through the main pancreatic duct toward the second portion of the duodenum. Discussion :Hemosuccuspancreaticus is a rare and potentially life-threatening obscure cause of upper gastrointestinal bleeding. It is described as bleeding from the ampulla of Vater via the pancreatic duct. It is one of least frequent cause of upper gastrointestinal bleeding and is most often caused by chronic pancreatitis, pancreatic tumours and sometimes pancreatic pseudocysts [ABSTRACT FROM AUTHOR]

BACKGROUND: Timely angiographic embolization of abdominopelvic injuries is a hallmark of a high-functioning trauma center. Yet, the process depends on the timely mobilization of interventional radiology staff. Smartphone technology to notify and mobilize staff may be a viable option. OBJECTIVE: To describe the incorporation of a smartphone application into our trauma workflow process previously developed for stroke care. METHODS: In 2022, our Level I trauma center implemented a smartphone application with three simultaneously occurring functions: (a) high-definition image viewing on the phone; (b) text messaging thread for all parties; and (c) a single-call activation system for staff mobilization. The application was initially developed to notify interventional radiologists of large-vessel occlusions in victims of stroke and, at our request, was modified to fit our trauma workflow process. The smartphone application company developed a new program, installed the application on trauma service smartphones, and provided educational in-services over a 1-month period. The application was then integrated into our trauma workflow process. RESULTS: The trauma surgeon and the interventional radiologist can now simultaneously view high-definition images on their smartphones. Text messages are accessible to all team members. The staff is notified and mobilized with the singlecall smartphone application, preventing the placing and returning of phone calls. CONCLUSION: Smartphone technology enhances timely interventional radiology staff response for hemorrhagic patients requiring emergent angioembolization. [ABSTRACT FROM AUTHOR]

This study reported two cases of acute life-threatening hemorrhage after Le Fort I osteotomy. In both cases, computed tomography and angiography revealed damage to the descending palatine artery, which was successfully treated by angiographic embolization. Although massive hemorrhage after Le Fort I osteotomy is rare, acute hemorrhage from the postoperative area may occur. Angiographic embolization is useful in cases of such hemorrhage from the posterior nasal cavity where endoscopic hemostasis is not possible. [ABSTRACT FROM AUTHOR]

Background/Purpose: Late hemorrhage following pancreatic surgery is associated with significant morbidity and mortality. Pseudoaneurysm (PSA) is an important source of late hemorrhage, which is effectively and safely managed by embolization. We aim to retrospectively review the outcomes of embolization for pseudoaneurysms causing late post-pancreatectomy hemorrhage over a period of six-years at our tertiary care center. Methods: Between 2014 and 2020, 616 pancreatic surgeries were performed and 25 patients had late hemorrhage (occurring > 24 hours post-operatively). The clinical parameters related to late hemorrhage, associated complications, embolization details, treatment success and their short-and long-term outcomes were analyzed. Results: Sixteen of 25 patients had PSA on digital subtraction angiography. Embolization was performed in these patients with technical and clinical success rates of 94.1% and 100%, respectively. Compared to patients without PSA, patients with PSA had significant hemoglobin drop (2.5 g/dL vs. 1.5 g/dL, p = 0.01), higher incidence of sentinel bleed (50% vs. 11.1%, p = 0.05) and lower requirement for surgery for bleeding (0% vs. 44.4%, p = 0.02). Clincally relevant postoperative pancreatic fistula and bile leak were seen in 72% and 52% of patients, respectively. Eight of these embolized patients died due to sepsis. The long-term outcome was good, once the patients were discharged. Conclusion: Late hemorrhage after pancreatic surgery was associated with high mortality due to complications such as pancreatic fistula and bile leak. Sentinel bleeding was an important clinical indicator of PSA. Angiographic embolization is safe and effective without any adverse short or long-term outcomes. [ABSTRACT FROM AUTHOR]

For patients with unstable abdominal trauma unresponsive to initial transfusion, the damage control strategy includes prompt hemostasis by open surgery and packing. Recently, a hybrid treatment that combines packing and transcatheter arterial embolization as a damage control strategy was reported to be effective; however, the indications and techniques are yet to be established. A 25-year-old male patient who was in shock due to severe liver injury after a traffic accident was brought to our emergency room by emergency services. After initial resuscitation, including resuscitative endovascular balloon occlusion of the aorta and blood transfusion, preoperative contrast-enhanced computed tomography indicated grade IV liver injury with active bleeding from the right hepatic artery. Damage control strategy with packing and subsequent transcatheter arterial embolization was determined to be useful. During treatment, bile leakage was observed. An endoscopic nasobiliary drainage tube was inserted, and the patient was treated conservatively. He was discharged on day 83 of hospitalization. Although using preoperative contrast-enhanced computed tomography before damage control surgery remains controversial, it can provide useful information to determine damage control strategy, including morphological evaluation of the injured area and the presence of active bleeding.

A pancreatic pseudocyst, typically resulting from acute pancreatitis, is a cystic lesion that lacks a true epithelial layer and can lead to various complications, including hemorrhage, which is most often associated with the splenic artery. Hemorrhage within a pseudocyst is a rare but severe complication, manifesting as intracystic, peritoneal, or gastrointestinal tract bleeding. We present a unique case of a 50-year-old male farmer with a history of acute pancreatitis who developed an intracystic hemorrhage due to ischemia in the splenic artery traversing a pancreatic pseudocyst. The patient was successfully treated with angiographic embolization after presenting with symptoms of gastrointestinal bleeding, hypotension, and abdominal pain. Initial management included conservative monitoring, but upon further complications, intervention became necessary. The patient's postoperative course was uneventful, and follow-up imaging confirmed the resolution of the hemorrhage and stabilization of the pseudocyst. This case underscores the importance of recognizing and promptly treating hemorrhagic pancreatic pseudocysts, particularly those involving visceral vessels. It also highlights the role of angiographic embolization as an effective treatment option. Given the rarity of such cases, our report aims to contribute to the growing body of literature and provide guidance for the management of similar cases in the future. Continued documentation and study of these cases are essential to developing standardized treatment protocols and improving patient outcomes., Competing Interests: Human subjects: Consent was obtained or waived by all participants in this study.

Introduction and objective: To report a single center experience with carotid body paraganglioma cases that were treated by the same surgeon in a city with high prevalence of paragangliomas due to high altitude. Methods: We retrospectively investigated the demographic, clinicopathological and radiological data of 104 patients diagnosed with cervical paragangliomas between 2003 and 2017. The patients were classified according to the Shamblin classification. Results: In this study a total of 104 patients (33 male and 71 female, with a mean age of 54.6 ± 13 years) diagnosed with cervical paragangliomas located on carotid bifurcation between 2003 and 2017 were included. Among those patients, 10 presented with bilateral tumors and in total, 114 paragangliomas were managed in this period. The mean diameter of the tumors was 5.12 ± 1.45 cm. Malignant tumor was determined in only one (0.9%) patient. All patients were operated. In 12 patients with the tumor diameter larger than 5 cm, preoperative coil embolization was achieved. In 14 patients, preoperative angiographic embolization was employed and in 4 patients intraoperative sclerosing agent injections were performed. Facial paralysis was observed in 2 patients and dysphagia was present in 1 patient, Horner syndrome was seen in 1 patient and hoarseness was reported in 7 patients after operation. All those complications improved during follow-up. Mortality was not reported in any cases. Conclusion: Surgery is the definitive treatment for patients with cervical paragangliomas. Although, it may be difficult in patients with the advanced Shamblin types, in experienced hands, complication rates are very low.

Hemosuccus pancreaticus is a rare but potentially torrential and life-threatening cause of acute upper gastrointestinal bleeding. It is described as an intermittent hemorrhage from the major duodenal papilla via the main pancreatic duct. Peripancreatic pseudoaneurysm following chronic pancreatitis is a common underlying etiology. However, gastroduodenal artery pseudoaneurysm-related hemosuccus pancreaticus remains exceedingly rare in the etiological spectrum of upper gastrointestinal bleeding. We hereby delineate a rare case of hemosuccus pancreaticus associated with gastroduodenal artery pseudoaneurysm in a patient who initially presented with abdominal pain and hematochezia. He was successfully managed with coil embolization without recurrence or sequelae. Furthermore, we conducted a search of the MEDLINE (PubMed and Ovid) database for relevant studies on hemosuccus pancreaticus published between inception and September 15, 2021. The available clinical evidence on causes, presentation patterns, diagnosis, and management was analyzed and summarized. This article highlights the rarity, the intermittent nature of hemorrhage, and the lack of a standardized diagnostic approach for this elusive disease. Clinicians should remain cognizant of hemosuccus pancreaticus, especially in patients presenting with symptoms and signs of intermittent gastrointestinal bleeding and abdominal pain. Prompt diagnosis carries paramount importance in saving patients from repeat hospital admissions and disease-associated morbidity and mortality. Conventional angiography with coil embolization may constitute an effective treatment strategy. [ABSTRACT FROM AUTHOR]

Purpose: This retrospective study was designed to evaluate the usefulness of multidetector computed tomography (MDCT) in the identification of heavy bleeding, as a determinant of angiographic embolization (AE) in patients with postpartum hemorrhage (PPH). Materials and Methods: Fifty-seven consecutively registered patients with PPH underwent contrast-enhanced MDCT at Kyungpook National University Hospital between January 2009 and December 2012. The characteristics of the 33 patients who showed extravasation (EV) of contrast material in MDCT (EV group) were compared with those of the 24 patients who had no EV (noEV group). AE was performed in 23 out of 57 cases, based on the decision of the treating clinician. Direct localization of the bleeding site was compared with the results of MDCT. Results: A greater proportion of the EV group required AE compared with the noEV group (64% vs. 8%). The EV group showed a greater estimated blood loss (EBL) (2,100 mL vs. 1,170 mL, p < 0.001) and was associated with the need for massive blood transfusion (6 pints vs. 3 pints, p < 0.001). Disseminated intravascular coagulation was observed more frequently in the EV group (36% vs. 8%, p = 0.027). Of the 33 patients who were managed conservatively without AE, EBL after MDCT was greater in the EV group than the noEV group (410 mL vs. 45 mL, p < 0.001). The comparison of computed tomographic and angiographic findings indicated a discordant result in only 1 case. Conclusions: Contrast-enhanced MDCT is helpful to determine which patients are candidates for AE and to reduce unnecessary angiographic intervention.

Purpose: Peri-operative major arterial haemorrhage after revision total hip arthroplasty (RTHA) is an odd but limb- and life-threatening complication. In this retrospective analysis, we sought to determine the prevalence of such injuries requiring selective catheter embolization or bypass after RTHA and to evaluate the associated mortality rate.Methods: Between 1995 and 2016, 2524 RTHAs were performed at a high-volume centre (1031 one-stage revisions, 1370 two-stage revisions and 123 resection arthroplasties). Throughout this period, nine patients presented with signs of persistent bleeding unaddressed during index surgery (9/2524; 0.35%), causing haemodynamic instability. All patients underwent angiographic exploration within the first 24 post-operative hours. Angiography evidenced four cases of bleeding pseudoaneurysms (three of them related to the common femoral artery and one to the medial circumflex femoral artery) and five cases of direct lacerations (one case in the inferior epigastric artery, one in the hypogastric artery, one in the external iliac artery, one in the popliteal artery and another in the superior gluteal artery).Results: Six cases underwent selective percutaneous angiographic embolization with gelatin microspheres, obtaining immediate haemodynamic stabilization; whereas three cases required a further bypass surgery with synthetic graft. Of the former group, four patients had an uneventful evolution, while two died at a mean of 49 days after surgery due to multi-organ failure (MOF). Two cases of the bypass group died because of MOF at a mean of 22 days. Overall mortality rate was 44%.Conclusions: The overall risk of arterial injury associated with RTHA was low. However, recognition of such a complication is imperative since it was associated with a high mortality rate. [ABSTRACT FROM AUTHOR]

Highlights • Radiographic assessment of spinal cord involvement is essential. • Histology is necessary to establish etiology, prognosis, and treatment plan. • Large tumors may require posterolateral thoracotomy and piecemeal resection. • Preoperative angiography may identify arteries shared by the tumor and spinal cord. • Preoperative angioembolization may reduce tumor vascularity and operative blood loss. Abstract Introduction: Posterior mediastinal masses present unique diagnostic and therapeutic challenges, particularly when large highly vascularized tumors extend toward or emanate from the spinal cord. The rare nature of these tumors precludes the development of standardized management algorithms, underscoring the importance of case reports. Presentation of case: A 57 year old female presented with exertional dyspnea and right chest pressure. Chest radiography followed by computed tomography (CT) scan demonstrated a 13 cm posterior mediastinal mass involving the T7 vertebral body. CT-guided percutaneous biopsy confirmed benign schwannoma. During open exploration, the tumor bled easily with contact. Angiography with intercostal arterial embolization decreased tumor vascularity while preserving spinal cord perfusion. Subsequent piecemeal resection facilitated exposure of the tumor base and complete resection. Postoperative recovery was uneventful. Discussion: Neurogenic tumors are most commonly located in the posterior mediastinum. When untreated, schwannomas continue to grow, and will inevitably cause compressive symptoms if given sufficient time. Therefore, resection is recommended. This may be performed thoracoscopically in select patients with small tumors, avoiding the morbidity of a thoracotomy incision. Conclusion: Large posterior mediastinal schwannomas require posterolateral thoracotomy and resection. Preoperative angiography helps identify arteries shared by the tumor and the spinal cord, and embolization may reduce tumor vascularity and operative blood loss thereby permitting safer resection.

Objective: To retrospectively analyze the clinical data and treatment procedures of angiographic embolization (AE) and extraperitoneal pelvic packing (EPP) for traumatic pelvic fractures in our center for the purpose of providing recommendations on the selection of treatment protocols., Methods: We analyzed 110 patients with traumatic pelvic fractures treated with AE and EPP from January 2015 to May 2023. The patients were divided into the AE group (69 men, 41 women) and the EPP group (20 men, 12 women). The primary outcomes were the mortality rate and incidence of complications., Results: The mortality rate was slightly lower in the AE than EPP group (7.3% vs. 9.4%). The overall blood transfusion volume was lower and the length of hospital stay was shorter in the AE than EPP group (7.79 ± 12.04 vs. 9.14 ± 14.21 units and 20.48 ± 11.32 vs. 22.14 ± 10.47 days)., Conclusions: Both AE and EPP have good treatment effects. AE is preferred for patients in stable condition with severe hemorrhage. This study suggests that EPP should be the primary treatment and that AE should serve as a complementary treatment for critical patients.

Purpose: To report a single center's experience with selective arterial embolization of the deep inferior epigastric arteries (DIEA) prior to pedicled TRAM flap breast reconstruction including techniques and outcomes.Materials and Methods: Retrospective chart review was performed for 15 patients who underwent pedicled TRAM flap breast reconstruction after selective embolization of bilateral DIEA. Data were analyzed to display the spectrum of postoperative outcomes following the TRAM flap procedure status post-selective angiographic embolization of the bilateral DIEA to improve vascularity of the TRAM flaps by rendering the tissue partially ischemic to undergo neovascularization. We then compared our results to historical controls of those delayed by ligating the DIEA via traditional surgical means to see if the outcomes are similar. We also compared our results to historical non-delayed TRAM flap reconstruction.Results: One patient had a small area of partial flap skin necrosis, and no patients had total flap loss. 13.3% of patients had clinically significant TRAM flap fat necrosis. Outcomes of TRAM flaps delayed by selective arterial embolization are comparable to historical controls of those delayed by traditional surgical means and better than non-delayed flaps.Conclusion: Angiographic delayed TRAM flap reconstruction procedure is a reasonable safe alternative to the surgical delayed TRAM flap reconstruction procedure with less morbidity and is better than non-delayed TRAM flap procedures.

Background: Endovascular management using angiographic embolization (AE) has been widely used with success as non operative management (NOM) in blunt hepatic trauma. We, in a tertiary care hospital in North of India, assess our use of endovascular management in patients of blunt and post operative trauma with active hepatic vascular bleeding and unstable hemodynamics in controlling bleeding. Methods: A retrospective review of inpatients from January 2006 to July 2012 requiring transarterial embolization/stenting for active hepatic vascular bleeding was done. All patients had evidence of ongoing hemorrhage as proved by clinical, laboratory and radiological findings in emergency settings. Angiographic intervention in an interventional suite with ongoing resuscitation was performed following which patients were monitored for morbidity and mortality benefits on intermediate follow up. Results: 10 adults and 3 children underwent AE with polyvinyl alcohol particle (PVA)/soft metal coil whereas 1 adult underwent revascularization with a covered stent for arterial bleeding. The mean age of case series was 36.18 ± 20.90 years with a mean liver injury computed tomography (CT) grade of 3.8 ± 0.83 in blunt trauma patients. The mean length of hospital stay was 9.62 ± 7.83 days and the mean follow up period of the group was 25.25 ± 21.02 months. All patients showed significant clinical improvement with prompt endovascular management resulting in no procedure related mortality. Conclusion: Prompt endovascular management is the modality of choice in comparison to NOM without AE in both pediatric and adult patients with hemodynamically compromised inaccessible intra hepatic vascular trauma.

Bilateral sudden sensorineural hearing loss is a rare otologic emergency and constitutes 0.44%-4.9% of overall sudden sensorineural hearing loss cases. Microvascular dysfunction secondary to systemic cardiovascular diseases, such as embolism, vasospasm, and hypercoagulability, is the main cause of non-idiopathic bilateral sudden sensorineural hearing loss. In this study, a case of bilateral sudden sensorineural hearing that occurred after angiographic embolization for treatment of aneurysmal subarachnoid hemorrhage was presented as a rare clinical condition.

Background: Although nonoperative management (NOM) has become standard care, optimal treatment of liver injuries in children is still challenging since many of these patients have multiple injuries. Moreover, the role of angiography remains poorly defined, and a high index of suspicion of complications is warranted. This study reviews treatment and outcomes in children with liver injuries at a major Scandinavian trauma centre over a 12-year period. Methods: Patients <17 years old with liver injury admitted to Oslo University Hospital Ullevaal during the period 2002-2013 were retrospectively reviewed. Data were compiled from the institutional trauma registry and medical records. Results: A total of 66 children were included. The majority was severely injured as reflected by a median injury severity score of 20.5 (mean 22.2). NOM was attempted in 60 (90.9%) patients and was successful in 57, resulting in a NOM success rate of 95.0% [95% CI 89.3 to 100]. Only one of the three NOM failures was liver related, occurred in the early part of the study period, and consisted in operative placement of drains for bile leak. Two (3.0%) patients underwent angiographic embolization (AE). Complications occurred in 18 (27.3% [95 % CI 16.2 to 38.3]) patients. Only 2 (3.0%) patients had liver related complications, in both cases bile leak. Six (9.1%) patients underwent therapeutic laparotomy for non-liver related injuries. Two (3.0%) patients died secondary to traumatic brain injury. Discussion: This single institution paediatric liver injury cohort confirms high attempted NOM and NOM success rates even in patients with high grade injuries and multiple accompanying injuries. AE can be a useful NOM adjunct in the treatment of paediatric liver injuries, but is seldom indicated. Moreover, bile leak is the most common liver-related complication and the need for liver-related surgery is very infrequent. Conclusion: NOM is the treatment of choice in almost all liver injuries in children, with operative management and interventional radiology very infrequently indicated. [ABSTRACT FROM AUTHOR]

Acute nonvariceal upper gastrointestinal bleeding is a common and life-threatening emergency. Despite optimal endoscopic and pharmacologic therapy, 8%-10% of patients continue to bleed or develop rebleeding. Surgery has been the traditional salvage treatment in these patients. However, surgery is associated with high morbidity and mortality rates. In the past few decades, transarterial embolization has emerged as a promising nonoperative alternative to surgery. High technical (69%-100%) and clinical success rate (63%-97%) were reported. However, comparative studies between the 2 treatment modalities are retrospective in nature. Current guidelines suggest transarterial embolization to be an alternative to surgery if expertise is available. This review attempts to summarize the published literature and to provide our view on the role of radiology and surgery for acute nonvariceal upper gastrointestinal bleeding refractory to endoscopic treatment. Factors leading to rebleeding and preventive measures to improve outcomes are also discussed. [ABSTRACT FROM AUTHOR]

Background: Life-threatening bleeding caused by liver injury due to chest compressions is a rare complication in otherwise successful cardiopulmonary resuscitation. Surgical intervention has been suggested to achieve bleeding control; however, reported mortality is high. In this report, we present a brief literature review and a case report in which use of a less invasive strategy was followed by an uneventful recovery. Case Presentation: A 37-year-old white woman was admitted after out-of-hospital cardiac arrest. Bystander cardiopulmonary resuscitation was immediately performed, followed by advanced cardiopulmonary resuscitation that included tracheal intubation, mechanical chest compressions, and external defibrillation with return of spontaneous circulation. Upon hospital admission, the patient's blood pressure was 94/45 mmHg and her heart rate was 110 beats per minute. Her electrocardiogram showed no signs of ST-segment elevations or Q-wave development. Coronary angiography revealed a proximal thrombotic occlusion of the left anterior descending coronary artery. Successful recanalization, after thrombus aspiration and balloon dilation followed by stent implant, was verified with normalized anterograde flow. Immediately after the patient's arrival in the intensive cardiac care unit, a drop in her blood pressure to 60/30 mmHg and a hemoglobin concentration of 4.5 g/dl were noticed. Transfusion was started, and bedside abdominal ultrasound examination revealed free intraperitoneal fluid. Computed tomography of the abdomen revealed liver injury with active extravasation from the cranial surface of the right lobe and a massive hemoperitoneum. The patient was coagulopathic and acidotic with a body temperature of 33.5 °C. A minimally invasive treatment strategy, including angiography and selective trans-catheter arterial embolization, were performed in combination with percutaneous evacuation of 4.5 L of intraperitoneal blood. After completion of these procedures, the patient was hemodynamically stable. She was weaned off mechanical ventilation 2 days later and made an uneventful recovery. She was discharged to a local hospital on day 13 without neurological disability. Conclusions: Although rare, bleeding caused by liver injury due to chest compressions can be life-threatening after successful cardiopulmonary resuscitation. Reported mortality is high after surgical intervention, and patients may benefit from less invasive treatment strategies such as those presented in this case report. [ABSTRACT FROM AUTHOR]

Hemosuccus pancreaticus is a rare cause of upper gastrointestinal bleeding (1/1500) and represents the loss of blood through the main pancreatic duct and its exteriorization through the major duodenal papilla. It can lead to massive bleeding, which is potentially life-threatening. This condition most commonly follows pseudoaneurysm formation due to acute or chronic pancreatitis. As a result of its infrequency, it is difficult to diagnose, and the mortality rate remains high. To our knowledge, this is the first case report on the Latin-American population. A 70-year-old male patient presented with diffuse severe abdominal pain associated with melaena. Angiotomography was performed, ruling out mesenteric ischemia, with evidence of pancreatic head tumor with liver metastases. Sandblom's triad was present and the diagnosis of hemosuccus pancreaticus was confirmed. Multiple arteriograms were performed, with pseudoaneurysm of gastroduodenal artery findings. Therefore, endovascular coil embolization was performed in two opportunities to control the bleeding. Upper gastrointestinal bleeding is a clinical challenge for the surgeon and emergency medicine. It's a complex entity with high mortality that should be suspected in patients with acute or chronic pancreatitis and periampullary tumors with non-established sources of bleeding. Clinically manifested by Sandblom's triad. Its diagnosis gold standard is arteriography plus embolization which is also therapeutic. Surgery is related to higher mortality and reserved for specific situations. • Hemossucus pancreaticus is a rare condition with increased risk of mortality • Endovascular management reduce morbidity rates • Pancreatic bleeding should be suspected in the presence of elevated amylase, abdominal pain and gastrointestinal bleeding.

BACKGROUND: Splenic artery embolization (SAE) in the presence of contrast blush (CB) has been recommended to reduce the failure rate of nonoperative management. We hypothesized that the presence of CB on computed tomography has minimal impact on patient outcomes. METHODS: A retrospective review was conducted of all children (<18 years) with blunt splenic trauma over a 10-year period at a level 1 pediatric trauma center. Data are presented as mean ± standard error of mean. RESULTS: Seven hundred forty children sustained blunt abdominal trauma, of which 549 had an identified solid organ injury. Blunt splenic injury was diagnosed in 270 of the 740 patients. All patients were managed nonoperatively without SAE. CB was seen on computed tomography in 47 patients (17.4%). There were no significant differences in the need for blood transfusion (12.5% vs 11.1%) or length of stay (3.1 vs 3.3 days) or need for splenectomy when compared in children with or without CB. CONCLUSION: Pediatric trauma patients with blunt splenic injuries can be safely managed without SAE and physiologic response and hemodynamic stability should be the primary determinants of appropriate management.

BACKGROUND: Management of splenic trauma has evolved, with current practice favoring selective angiographic embolization and non-operative treatment over immediate splenectomy. Defining the optimal selection criteria for the appropriate management strategy remains an important question. METHODS: This retrospective registry review was conducted at a Level I trauma center. The patient population consisted of 20,561 patients in the State Trauma Registry from April 2004 to May 2012. Splenectomy, angiography, splenic embolization, nonoperative, and noninterventional (NI) observation were the management strategies under study. Morbidity and mortality were the outcome measures. Morbidity and mortality by management strategy. RESULTS: During the 8-year study period, 926 (4.5%) patients sustained splenic injury. Observational management increased over time despite the similar distribution of splenic injury grade over the study period: grade I/II (50%), grade III (24.2%), and grade IV/V (25.8%). Mortality rates associated with each management strategy were the following: immediate splenectomy (IS; 25%), splenic embolization (SE; 3.9%), and angiography only or observation, that is, NI (6.5%) management. Injury severity score (ISS) was highest in IS (36.1 ± 1.3) compared with SE (29.1 ± 1.0, P = .001) and NI (21.6, P < .001). Splenectomy was required in 5 of the 129 (3.9%) patients managed with SE and 9 of the 677 (1.3%) patients managed by NI. Mortality was significantly lower among those managed by SE (odds ratio .12, 95% confidence interval: .05 to .32) or NI (odds ratio .21, 95% confidence interval: .12 to .35). This survival benefit was explained by the association of IS with systolic blood pressure <90, high ISS, low GCS at presentation, ISS, development of shock, need for transfusion, and multiorgan failure. CONCLUSIONS: In this large 8-year single institution study, we observed an increase in nonoperative management by an increased application of angiography and embolization. An aggressive utilization of SE in patients with appropriate indications will result in low failure rates and improved mortality. [ABSTRACT FROM AUTHOR]

A 77-year-old man with a progressively dry cough (two months duration) was admitted with hemoptysis. Chest computed tomography ( CT) revealed left lingular lobe consolidation and one thick-walled cavity lesion over the left lower lobe, which was accompanied by satellite micro-nodules in a tree-in-bud pattern. CT-guided biopsy confirmed mycobacterial infection, and subsequent culture yielded Mycobacterium avium complex ( MAC). Unremitting hemoptysis was present despite treatment (14 days) with ethambutol, rifampin, clarithromycin, and streptomycin. Initial CT angiography ( CTA) to determine the source of the hemoptysis revealed a suspected aneurysm in the consolidated left lingular lobe; however, this could not be localized via catheter angiography during the pulmonary and bronchial arterial phases. Two weeks later, a massive hemoptysis episode led to haemodynamic instability and serious consequences. Follow-up CTA confirmed the previously detected aneurysm, and glue embolization was performed successfully. This case report highlights a rare but catastrophic MAC-associated pseudoaneurysm and relevant treatment options. [ABSTRACT FROM AUTHOR]

Background A common dilemma in the management of pelvic fractures is recognizing the presence of associated abdominal injury. The purpose of this study was to determine the association between initial therapeutic intervention (laparotomy or transcatheter arterial embolization (TAE)) and mortality. Methods This was a cohort study using the Japan Trauma Data Bank between 2004 and 2010, including blunt trauma patients with pelvic fractures and positive Focused Assessment with Sonography in Trauma (FAST) results. Eligible patients were restricted to those who underwent laparotomy or TAE/angiography as the initial therapeutic intervention. Crude and adjusted odds ratio (AOR) for in-hospital mortality were compared between the laparotomy first and TAE first groups (reference group). Multiple logistic regression analysis and propensity score adjusted analysis were used to adjust for clinically relevant confounders, including the severity of injury. Results Of the 317 participants, 123 patients underwent laparotomy first and 194 patients underwent TAE first. The two groups were similar in terms of age, although the laparotomy first group had higher mean Injury Severity Scores (ISS) and higher mean scores based on the abdominal Abbreviated Injury Scale (AIS), as well as lower mean pelvic AIS and systolic blood pressure (SBP). Half of the patients who were hypotensive (SBP < 90 mmHg) on arrival underwent TAE first. The laparotomy first group had a significantly higher crude in-hospital mortality (41% vs. 27%; P < 0.01). After adjusting for confounders, the choice of initial therapeutic intervention did not affect the in-hospital mortality (AOR, 1.20; 95% Confidence Interval (CI), 0.61-2.39). Even in the limited subgroup of hypotensive patients (SBP 66-89 mmHg and SBP < 65 mmHg subgroup), the effect was similar (AOR, 1.50; 95% CI, 0.56-4.05 and AOR, 1.05; 95% CI, 0.44-3.03). Conclusions In Japan, laparotomy and TAE are equally chosen as the initial therapeutic intervention regardless of hemodynamic status. No significant difference was seen between the laparotomy first and TAE first groups regarding in-hospital mortality. [ABSTRACT FROM AUTHOR]

Peroral endoscopic myotomy (POEM) has been shown to be an effective treatment for achalasia and with few adverse events. Only a few cases of delayed bleeding have been described. This current case report describes a patient with delayed bleeding in the submucosal tunnel on the eighth day after POEM. The patient was a 21-year-old woman with a 4-month history of dysphagia, vomiting and excessive weight loss. Achalasia was diagnosed according to her symptoms, barium oesophagogram, oesophageal manometry and endoscopy examination. POEM was performed by an experienced operator. On the eighth day after POEM, the patient suddenly developed continuous haematemesis presented with vomiting of fresh blood and melena. An emergency exploratory esophagogastroduodenoscopy was performed. A large number of blood clots were found at the wound and a long haematoma was found along the lining of the submucosal tunnel. Re-entry into the submucosal tunnel and exposure of the haemorrhagic site was attempted but failed because of severe submucosal tissue adhesion. An emergency angiography was undertaken and haemostasis was achieved with superselective arterial microcoil embolization.

Pancreatic pseudocysts are seen both in acute and chronic pancreatitis. Prevalence of pancreatic pseudocyst in chronic pancreatitis is 20% to 40% and is most commonly seen in alcoholic chronic pancreatitis. Intracystic hemorrhage from a pseudoaneurysm is a rare and potentially a lethal complication of pancreatic pseudocyst with an incidence of less than 10%. We herein present a case of a 42-year-old male with a past medical history of chronic alcoholic pancreatitis, stable pseudocyst in the tail of pancreas, alcohol abuse and seizures who presented with abdominal pain and acute anemia had this rare complication of hemorrhagic pseudocyst. The diagnostic modalities used to diagnose hemorrhagic pseudocyst are ultrasound with color doppler, CT with contrast, digital subtraction angiography and angiography. Angiographic embolization of the culprit artery is the preferred treatment of choice in the treatment of pseudoaneurysms. It is important for early recognition and treatment of this complication as the mortality can be as high as 40%. [ABSTRACT FROM AUTHOR]

Abstract: Purpose: The management of hemodynamically unstable patients with severe pelvic fractures remains a challenge. Various treatment strategies have been advocated. This study analyzed the value of transcatheter angiographic embolization (TAE) for persistent haemodynamic instability after initial fracture stabilization. Materials and methods: From January 2002 to July 2011, 803 patients were identified with pelvic fractures, 295 of them (37%) were presenting with unstable pelvic fractures. Fifteen patients, all with unstable fractures (2%), remained hypotensive (systolic blood pressure<90mmHg) despite adequate fluid resuscitation and emergent surgical fracture stabilization, subsequently underwent TAE. Results: The median age in the TAE-group was 57.9 years±20.12 (min 22; max 82) and the median ISS (injury severity score) was 35.8±11.7 (min 22; max 66). 13 out of 15 patients (87%) received initial external fixation and 2 patients (13%) where treated with a C-Clamp before TAE. Radiological success, defined as absence of contrast extravasation on completion angiography, was observed in all 15 patients. In total 3 (20%) patients died during the period of hospitalization, none of them owing to persistent or recurrent pelvic haemorrhage. In the remaining 12 patients, no early or late complications of TAE were identified. Preperitoneal pelvic packing was performed in two patients, both had open pelvic fractures. Conclusion: TAE is a safe and very efficient procedure to treat persistent haemorrhage in patients with unstable pelvic fractures initially treated by surgical fracture stabilization procedures. On the long term, no early or late bleeding recurrence could be demonstrated with an overall survival rate of 80%. Preperitoneal pelvic packing can be reserved for patients with open fractures and active bleeding. [Copyright &y& Elsevier]

Management of massive liver trauma (grades IV-VI) is associated with high morbidity and mortality. It can pose serious challenges to treating physician and requires multimodality interventions. For a successful outcome, timing of intervention is crucial. We report a case of grade V hepatic injury treated successfully with angioembolization, laparoscopic lavage, and endoscopic stenting during a time period from admission to discharge on the 24th day. Angioembolization was performed at admission after resuscitation as CT scan showed active extravasation in the arterial phase. Laparoscopic lavage and drainage was performed on the fifth day as abdominal inflammatory response failed to respond to medical management. There was biliary component of abdominal fluid noticed during laparoscopy, which manifested by postoperative localized biliary fistula; hence endoscopic stenting of the bile duct was performed on the seventh day. The patient recovered well with timely minimal invasive approach and was fine at 1 year follow-up. [ABSTRACT FROM AUTHOR]

After the liver, the spleen is the second most commonly injured organ in blunt abdominal trauma. The past two decades have witnessed a trend towards non-surgical management of these injuries, and transarterial embolization (TAE) has greatly contributed to avoiding unnecessary laparotomies, especially in haemodynamically stable patients. We present the case of a 21-year-old male patient involved in a motor accident with subsequent injury of the left thorax and fracture of the left ulna. Abdominal computed tomography revealed the presence of a parenchymal haematoma and a pseudoaneurysm of the splenic artery. Since the patient was haemodynamically stable, he was admitted to the clinic and the pseudoaneurysm was treated with distal selective TAE. Six months later, he remains asymptomatic without signs of pathology on Doppler ultrasound at follow-up. The use of these modalities can contribute to better success rates of NOM and should be readily available at any hospital treating trauma patients. [ABSTRACT FROM AUTHOR]

Purpose: The control of arterial bleeding associated with pelvic ring and acetabular fractures (PRAF) remains a challenge for emergency trauma care. The aim of the present study was to uncover early prognostic mortality-related factors in PRAF-related arterial bleedings treated with transcatheter angiographic embolization (TAE). Methods: Forty-nine PRAF patients (46 pelvic ring and three acetabular fractures) with arterial pelvic bleeding controlled with TAE (within 24 h) were evaluated. Results: All large arterial disruptions ( n = 7) were seen in type C pelvic ring injuries. The 30-day mortality in large vessel (iliac artery) bleeding was higher (57 %) than in medium- or small-size artery bleeding (24 %). Overall 30-day mortality was 29 %. No statistically significant difference in the first laboratory values between the survivors and nonsurvivors was found. However, after excluding patients dying of head injuries ( n = 5), a reasonable cut-off value was identified for the base excess (BE; lower than −10 mmol/l) obtained on admission. Conclusions: PRAF patients with exsanguinating bleeding from the large pelvic artery have the worst prognosis. Very low BE values (<−10.0 mmol/l) on admission for exsanguinating patients have a negative predictive value for survival, thus anticipating a poor outcome in bleeding controlled with TAE only and an increased risk of death. In critical cases, an aggressive bleeding control protocol prompts extraperitoneal pelvic packing prior to TAE. PRAF-related rupture of the external iliac artery is rare and indicates surgical techniques in controlling and restoring blood supply to the lower leg. [ABSTRACT FROM AUTHOR]
