Endovascular Stenting and Stent-graft Repair of a Hemorrhagic Superior Mesenteric Artery Pseudoaneurysm and Dissection Associated with Pancreaticoduodenectomy

This report presents a 73-year-old woman with intraperitoneal bleeding from a superior mesenteric artery (SMA) pseudoaneurysm and dissection after pancreaticoduodenectomy (PD). A self-expanding bare metal stent was placed in the distal SMA across the area of dissection, and a stent-graft was subsequently placed across the pseudoaneurysm emerging from the proximal site by overlapping the bare stent, resulting in complete exclusion of the pseudoaneurysm and control of the dissection. Bleeding was controlled after the endovascular procedure. The combination of endovascular stenting and stent-graft repair is feasible and useful in comorbid cases of SMA pseudoaneurysm and dissection.
