- W1985118841 abstract "Purpose To evaluate the safety and efficacy of two transcatheter arterial embolization (TAE) techniques used to treat pseudoaneurysms of the gastroduodenal artery (GDA) stump after pancreaticoduodenectomy. Materials and Methods Between March 2003 and March 2008, 16 patients were treated with TAE for pseudoaneurysms of the GDA stump after pancreaticoduodenectomy. Two embolization techniques were employed: endovascular trapping of the hepatic artery (embolization of the hepatic artery proximal and distal to GDA stump; group A; n = 13) and selective embolization of the GDA stump and/or pseudoaneurysm sparing hepatic arterial flow (group B; n = 3). Technical success, initial hemostasis, recurrence of bleeding, and complications were compared between the two groups retrospectively. Results All TAE procedures were technically successful and immediate hemostasis was achieved in all patients. There was no recurrent bleeding in group A; however, all three patients in group B experienced recurrent bleeding after initial hemostasis (P = .002), and these patients required subsequent embolization with the endovascular trapping technique. Two patients died of multiple organ failure (one patient in each group) despite successful hemostasis. Three patients experienced subsegmental (n = 1, group A) and multisegmental (n = 2, group B) liver infarction, which were successfully managed with conservative treatment. There was a higher incidence of major complications in group B (15.4% vs 100%; P = .018). Conclusions Endovascular trapping of the hepatic artery is a safe and effective treatment of pseudoaneurysms of the GDA stump after pancreaticoduodenectomy. Hepatic ischemic complications are not rare, but can be conservatively managed. Selective embolization of the GDA stump and/or pseudoaneurysm is frequently associated with recurrence of bleeding, which eventually leads to major complications.
