Acute Dissection of the Middle Colic Artery Immediately after Endovascular Abdominal Aortic Aneurysm Repair: A Case Report

Abstract

A 78-year-old man underwent endovascular abdominal aortic aneurysm repair (EVAR) for a true aortic aneurysm. He developed sudden abdominal pain 4 hr after EVAR. Angiography revealed a dissected aneurysm of the middle colic artery (MCA). Despite conservative treatment, follow-up computed tomography revealed an expanded aneurysm of the MCA. We therefore performed coil embolization of the dissected MCA to prevent a rupture of the aneurysm. There has never been a reported case of acute dissection of the MCA immediately after EVAR that was not caused by catheters. In this report, we discuss the possible underlying mechanisms and the optimal therapeutic strategy for this rare complication.

Aneurysm

Aneurysms are outward distensions or bulges that occurs in a weakened wall of blood vessels. Discover the latest research on aneurysms here.

Cardiac Aneurysm

Aneurysm refers to a bulge of the wall or lining of a vessel commonly occurring in the blood vessels at the base of the septum or within the aorta. In the heart, it usually arises from a patch of weakened tissue in a ventricular wall, which swells into a bubble filled with blood. Discover the latest research on cardiac aneurysm here.

Aortic Aneurysm

An aortic aneurysm is the weakening and bulging of the blood vessel wall in the aorta. This causes dilatation of the aorta, which is usually asymptomatic but carries the risk of rupture and hemorrhage. Find the latest research on aortic aneurysms here.
