Purpose: Hepatic arterioportal fistula (HAPF) is an uncommon complication of hepatic trauma, which can manifest with abdominal pain and the sequelae of portal hypertension months to years after injury. The purpose of this study is to present cases of HAPF from our busy urban trauma center and make recommendations for management. Methods: One hundred and twenty-seven patients with high-grade penetrating liver injuries (American Association for the Surgery of Trauma [AAST] - Grades IV-V) between January 2019 and October 2022 were retrospectively reviewed. Five patients were identified with an acute hepatic arterioportal fistula following abdominal trauma from our ACS-verified adult Level 1 trauma center. Institutional experience with overall surgical management is described and reviewed with the current literature. Results: Four of our patients presented in hemorrhagic shock requiring emergent operative intervention. The first patient had postoperative angiography and coil embolization of the HAPF. Patients 2 through 4 underwent damage control laparotomy with temporary abdominal closure followed by postoperative transarterial embolization with gelatin sponge particles (Gelfoam) or combined Gelfoam/n-butyl cyanoacrylate. The final patient went directly for angiography and Gelfoam embolization after identification of the HAPF. All 5 patients had resolution of HAPF on follow-up imaging with continued post management for traumatic injuries. Conclusion: Hepatic arterioportal fistula can present as a complication of hepatic injury and manifest with significant hemodynamic aberrations. Although surgical intervention was required to achieve hemorrhage control in almost all cases, management of HAPF in the setting of high-grade liver injuries was achieved successfully with modern endovascular techniques. A multidisciplinary approach to such injuries is necessary to optimize care in the acute setting following traumatic injury. [ABSTRACT FROM AUTHOR]

Spontaneous rupture of the iliac vein is a rare cause of retroperitoneal hematoma. A misdiagnosis may delay the treatment and consequently put the patient in a life-threatening emergency. We report the case of a 73-year-old woman who presented with hemorrhagic shock from bleeding caused by a large left retroperitoneal hematoma. She was successfully treated with an endovascular approach by using a double bare stent technique. An extensive review of the literature was conducted and a total 44 articles with 50 patients were identified. Among these patients, 88.2% were women, 94.1% presented with a left-sided rupture, and the mortality rate was 13.7%. Spontaneous iliac vein rupture was more likely to occur in the left side in female patients. Conservative treatment was an option in hemodynamically stable patients. Exploratory laparotomy and surgical iliac vein repair was necessitated in most patients. Endovascular treatment including placement of covered stent and coil embolization had been widely used to treat spontaneous vein rupture since 2003. Double bare stent technique was also an effective alternative if a suitable covered stent was unavailable. [ABSTRACT FROM AUTHOR]

Ureteroarterial fistula (UAF) is a rare but life-threatening condition because of massive hemorrhage. Risk factors include degenerative vascular diseases, previous vascular surgery, pelvic radiation, chemotherapy, pelvic surgery, and prolonged ureteral stenting. The most common presentation of UAF is massive hematuria with hemorrhagic shock. The diagnosis is always difficult even with angiography. Endovascular repair with stenting and/or coiling is effective and safe. The surgical treatment should be used in recurrent UAF cases. We reported a rare case describing rapid management of a UAF in a patient who presented with hematuria even when we had no diagnosis on the initial CT scan. The patient was in shock. Deployment of a stent graft within the common iliac artery bypassing the UAF was performed. The patient improved rapidly. [ABSTRACT FROM AUTHOR]

Background: Renal artery–inferior vena cava (IVC) fistula is usually caused by penetrating injury to the back. However, it is a very rarely reported entity with only 20 cases reported in the literature. They may present acutely with hemodynamic instability or chronically as congestive heart failure. A thorough examination and adequate imaging are required to avoid missing such injuries. Case Presentation: A 28-year-old gentleman presented after sustaining stab injury to the back. The stab had penetrated the renal artery and IVC, leading to arteriovenous fistula. He was managed surgically, as he went into hemorrhagic shock, with a successful outcome. The case is also unique as an accessory renal artery was also involved in the fistula. Conclusion: Early identification and management of renal artery–IVC fistula is important to ensure a successful outcome. Such fistulas can be managed by either endovascular approach or surgical approach. The decision of approach depends on the level of expertise available and hemodynamic status of the patient.

Introduction: A 90-year-old patient was admitted with a hemorrhagic shock from a huge ruptured abdominal aortic aneurysm with an unfavourable infrarenal aortic neck and a horseshoe kidney (HSK). Report: We decided on an open surgical approach: the HSK isthmus was sectioned with an Endo GIA 45 mm, and we performed a suprarenal aortic cross-clamping and an aortic graft reconstruction. Postoperatively, no urinary leakage was detected, and renal function showed no impairment. The patient died on the 10th postoperative day from pneumonia. Conclusion: We believe that the sectioning of the HSK isthmus with Endo GIA is a fast and simple maneouvre. [ABSTRACT FROM AUTHOR]
