Short- and long-term follow-up after transarterial embolization of a giant inferior mesenteric artery aneurysm

Abstract

Among the cases of visceral artery aneurysms, those that involve the inferior mesenteric artery are the most uncommon, with a prevalence of <1%. This study reports a giant symptomatic inferior mesenteric artery aneurysm and its endovascular treatment by means of percutaneous embolization with the implantation of pushable coils. After complete occlusion of the aneurysm, adequate maintenance of arterial supply of the left colon and resolution of the symptoms were observed. In the 2-year follow-up, a significant reduction in the aneurysm's volume and maintenance of the clinical condition were observed.

Surgical Excision of a Contained Rupture of an Inferior Mesenteric Aneurysm

“…The patency of the collateral blood supply to the bowel (marginal artery of Drummond) is important when vessel embolisation is being considered. 13 The main contraindication to endovascular approach as a definitive repair would be infective mycotic aneurysms. The introduction of foreign body into an infective field is not justified without prolonged course of antibiotic therapy first.…”
