Ruptured Superficial Femoral Artery Anastomotic Pseudoaneurysm after 30 Years.

INTRODUCTION: Anastomotic pseudoaneurysms are a complication of vascular reconstructive surgery with the majority in the femoral region. Although rare, ruptured femoral anastomotic pseudoaneurysms have high mortality and require emergency surgery. CASE PRESENTATION: A 60-year-old male with a history of a left leg crush injury was treated with a superficial femoral artery interposition vein graft 30 years ago. He presented nowadays with a three-day history of severe pain in his left thigh. CT angiography demonstrated a ruptured anastomotic pseudoaneurysm with contrast extravasation into an intramuscular hematoma. He had significant scarring from his previous surgeries which made the leg hostile for an open repair. Therefore, percutaneous access selectively cannulated the left iliofemoral vasculature. An angiogram showed a distal superficial femoral artery pseudoaneurysm. Subsequently, two 10mmx15cm Viabahn covered stents (Gore & Associates, Flagstaff, AZ) were placed bridging healthy superficial femoral artery. A completion angiogram demonstrated no extravasation into the pseudoaneurysm. The patient recovered and was discharged home two days postoperatively. CONCLUSION: Ruptured femoral anastomotic pseudoaneurysms are traditionally repaired with open pseudoaneurysm excision and arterial reconstruction, although endovascular repair has been reported. Furthermore, most femoral anastomotic pseudoaneurysms form less than 10 years after initial operation. We present a unique case of ruptured superficial femoral artery pseudoaneurysm, 30 years after the initial operation. Endovascular stents offer effective treatment for ruptured anastomotic pseudoaneurysms.

Portojejunostomy in Split Liver Transplantation as a Rescue Technique for Challenging Biliary Reconstruction: A Case Report.

Cadaveric split liver transplantation (SLT) is a valid option to increase the pool of cadaveric organs, obtaining 2 functioning grafts from a single donor. Typically, SLT is performed for 1 adult and 1 pediatric recipient. However, on the heels of great results achieved in living donor liver transplantation, splitting cadaveric liver into full right graft and full left graft for 2 adults has become a feasible idea. The rate of biliary complications remains the "Achilles heel" in partial graft liver transplantation, either from cadaveric or living donors. In cases of biliary complications, interventional radiology and/or endoscopic procedures are the cornerstone of management. Surgical revision is left as the last option. When surgical revision fails, retransplantation becomes the only rescue option. Herein we describe the case of a cadaveric SLT, complicated by biliary leakage in the presence of multiple bile ducts. A duct-to-duct anastomosis was not feasible. Therefore, a hepaticojejunostomy was performed and resulted in a high-output biliary leak from different sources. Given the anatomy of the biliary tree, radiologic interventional measures were not feasible to address the leak. The idea of performing a portoenterostomy to restore bilioenteric continuity proved to be successful. Portoenterostomy should not be performed in lieu of other alternatives, but rather as the last option to avoid retransplantation in cases of complicated biliary reconstruction after partial graft liver transplant.

Case reports of atrial and pericardial rupture from blunt cardiac trauma.

BACKGROUND: Blunt cardiac trauma is diagnosed in less than 10% of trauma patients and covers the range of severity from clinically insignificant myocardial contusions to lethal multi-chamber cardiac rupture. The most common mechanisms of injury include: motor vehicle collisions (MVC), pedestrians struck by motor vehicles and falls from significant heights. A severe complication from blunt cardiac trauma is cardiac chamber rupture with pericardial tear. It is an exceedingly rare diagnosis. A retrospective review identified only 0.002% of all trauma patients presented with this condition. Most patients with atrial rupture do not survive transport to the hospital and upon arrival diagnosis remains difficult. CASE PRESENTATION: We present two cases of atrial and pericardial rupture. The first case is a 33-year-old female involved in a MVC, who presented unresponsive, hypotensive and tachycardic. A left sided hemothorax was diagnosed and a chest tube placed with 1200 mL of bloody output. The patient was taken to the OR emergently. Intraoperatively, a laceration in the right pericardium and a 3 cm defect in the anterior, right atrium were identified. Despite measures to control hemorrhage and resuscitate the patient, the patient did not survive. The second case is a 58-year-old male involved in a high-speed MVC. Similar to the first case, the patient presented unresponsive, hypotensive and tachycardic with a left sided hemothorax. A chest tube was placed with 900 mL of bloody output. Based on the output and ongoing resuscitation requirements, the patient was taken to the OR. Intraoperatively, a 15 cm anterior pericardial laceration was identified. Through the defect, there was brisk bleeding from a 1 cm laceration on the left atrial appendage. The injury was debrided and repaired using a running 3-0 polypropylene suture over a Satinsky clamp. The patient eventually recovered and was discharged home. CONCLUSIONS: We present two cases of uncontained atrial and pericardial rupture from blunt cardiac trauma. Contained ruptures with an intact pericardium present as a cardiac tamponade while uncontained ruptures present with hemomediastinum or hemothorax. A high degree of suspicion is required to rapidly diagnose and perform the cardiorrhaphy to offer the best chance at survival.

Obstructive Uropathy because of a Large Rectus Sheath Haematoma: A Case Report of Combined Interventional Radiology and Surgical Approach.

INTRODUCTION: Rectus sheath haematomas associated with anticoagulation are often self limiting. When large, however, they can even extend into the pelvis and cause compression of adjacent organs such as the bladder. A combined endovascular and surgical approach can decrease the operative exposure necessary to treat this occurrence. REPORT: A 42 year old morbidly obese African American female on warfarin treatment for pulmonary embolism presented outside the hospital with pneumonia. During her hospitalisation, she developed a spontaneous right rectus abdominis haematoma below the level of the umbilicus with active bleeding in the extraperitoneal space causing mass compression of the bladder. She developed acute renal failure and became anuric. Following endovascular embolisation of the inferior epigastric artery, surgical exploration was successfully performed to remove the haematoma and relieve the urinary obstruction. Diuresis resumed and renal function normalised without any further evidence of bleeding. DISCUSSION: A large rectus sheath haematoma that extends into the bladder causing renal obstruction can be treated by endovascular embolisation and surgical exploration to limit operative risks and exposure in morbidly obese patients.
