Gastroduodenal artery pseudoaneurysm causing obstructive jaundice

Abstract

Background: Visceral artery aneurysms and pseudoaneurysms are uncommon phenomena with a high mortality rate in cases of rupture. These rare vascular pathologies are usually asymptomatic and are therefore generally discovered incidentally on computed tomography or magnetic resonance imaging examination. Current therapeutic options have trended toward a minimally invasive approach because of evolving endovascular treatment options, with open operations typically reserved for cases of intraabdominal hemorrhage. Case Report: We describe a case of gastroduodenal artery pseudoaneurysm manifesting as obstructive jaundice and pancreatitis because of extrahepatic compression of the common bile duct and pancreatic duct by mass effect. Open repair was ultimately required secondary to arterial anatomy that was not amenable to any endovascular treatment approach. Conclusion: While endovascular options are the preferred treatment modality for visceral artery aneurysms and pseudo-aneurysms, some cases require definitive open repair for a variety of reasons, including unsuitable anatomy.
