title: Endovascular management of anastomotic blowout of proper hepatic to common hepatic artery saphenous vein bypass with coil embolization and hepatic artery stent placement.
abstract: Mesenteric and visceral artery pseudoaneurysms in the abdomen are a relatively rare complication after abdominal surgery. It is a complication primarily associated with pancreatic and hepatobiliary surgery, trauma, iatrogenic causes and inflammatory diseases. Regardless of etiology, visceral artery pseudoaneurysms of the abdomen reportedly occur only in 0.01% to 2% of the population. Although rare, these are associated with life-threatening bleeding complications and need to be appropriately managed. We present the case of a patient who presented with bleeding after developing a pseudoaneurysm at the distal anastomotic site of a common hepatic to proper hepatic artery interposition saphenous vein bypass that was subsequently excluded by coil embolization and stent graft placement.
