Prevention of Type II Endoleak by Laparoscopic Inferior Mesenteric Artery Ligation

Abstract

Abdominal aortic aneurysm repair by endovascular techniques have gained wide acceptance as a treatment option. A potential well-known complication of endovascular repair includes endoleak. Specifically, type II endoleak, which is described as retrograde flow into the aneurysm sac through collateral vessels, can occur in up to 30% of patients. Certain preoperative factors can predict which patients may develop type II endoleak. This article describes laparoscopic inferior mesenteric artery ligation prior to endovascular abdominal aortic aneurysm repair as a viable treatment option in the prevention of type II endoleak.

Role of aneurysm sac embolization during endovascular aneurysm repair in the prevention of type II endoleak-related complications

“…Recently, on the basis of different experience, there has been a trend toward preventing EIIs instead of treating their complications after they develop. Brenes et al 12 reported laparoscopic IMA ligation before EVAR; Muthu et al 13 have described routine intraoperative selective IMA embolization and thrombin injection into the aneurysm sac just before EVAR.…”
