Ureteral leak after an abdominal aortic aneurysm repair: case report.
Iatrogenic ureteral injuries are an infrequent complication of vascular reconstructive surgery, and if they are not suspected at the time of surgery the diagnosis is usually delayed. Diagnosing these injuries may be challenging, since patients usually show signs and symptoms appropriate to a normal postoperative course and usually do not develop hematuria or renal dysfunction. In the proper clinical setting, a fluid collection adjacent to the ureter on cross-sectional imaging studies should alert the emergency radiologist to the possibility of ureteral injury. A high clinical suspicion would allow earlier diagnosis and treatment, potentially reducing the morbidity and mortality associated with a delay in diagnosis. We present a case of a ureteral leak diagnosed 1 week after an abdominal aortic aneurysm repair. A fluid collection seen adjacent to the ureter on contrast-enhanced CT prompted the radiologist to obtain delayed images that demonstrated urinary extravasation.

Hepatic transplant complicated by hepatic artery thrombosis and bile duct necrosis: case report and potential application of contrast-enhanced MR cholangiography following intravenous mangafodipir trisodium in the emergency room setting.
Biliary tract strictures and leaks are the second most common complications following orthotopic liver transplantation. Nonanastomotic bile duct complications are most often caused by hepatic artery thrombosis and can result in fulminant hepatic necrosis, bile duct strictures, and bile duct leaks that increase the risk of cholangitis, sepsis, and abscess. The emergency physician and radiologist should strongly suspect biliary disease in a post-transplant patient presenting with elevated liver function tests, jaundice, fever, and/or abdominal pain in order to achieve diagnosis and treatment rapidly. We present the case of a liver transplant patient who developed bile duct necrosis and hepatic infarction secondary to hepatic artery thrombosis 5 months after surgery. In addition, we discuss a new contrast-enhanced MR cholangiographic technique that has the potential to be performed in the emergency setting as the only diagnostic test prior to appropriate therapy.

Recurrent gallstone ileus: a case report.
Gallstone ileus is a rare complication of recurrent gallstone cholecystitis and usually occurs in elderly female patients. Recurrent gallstone ileus occurs in 5% of patients with a previous episode of gallstone ileus and is associated with a mortality of 20%. We present a 52-year-old female with recurrent gallstone ileus 1 year after her initial episode.
