Endovascular Stent Exclusion of a Hepatic Artery Pseudoaneurysm

Presented is a patient with an iatrogenic hepatic artery pseudoaneurysm that was treated by endovascular stent grafting. Endovascular stent grafting of a hepatic artery pseudoaneurysm offers a safe and potentially less morbid alternative to an open repair. The report stresses the necessity of careful preoperative evaluation with angiography to determine the feasibility of the procedure. An aggressive approach to treating hepatic artery pseudoaneurysms is advocated because of the poor correlation between size and their tendency to rupture. With an increasing rate of diagnosis of visceral artery aneurysms in elderly, debilitated patients, endovascular repair is anticipated to have an increasing role and should be considered a first-line therapy in anatomically suitable candidates.
