# Delayed Stanford Type A Aortic Dissection After Endovascular Repair of Abdominal Aortic and Common Iliac Artery Aneurysms Resulting in Stent Graft Collapse: A Case Report

## TL;DR

A rare case of aortic dissection occurred after a patient's abdominal aortic and iliac artery aneurysms were repaired with a stent graft, leading to fatal complications.

## Contribution

This case report highlights a rare complication of stent graft collapse and TAAD following endovascular repair.

## Key findings

- TAAD occurred months after EVAR of abdominal aortic and common iliac artery aneurysms.
- The dissection was likely caused by atherosclerosis, hypertension, and prior aortic valve replacement, not the EVAR procedure.
- Only a few cases in the literature report TAAD and total collapse of the abdominal aortic stent graft.

## Abstract

We discuss a rare case of Stanford type A aortic dissection (TAAD) occurring several months after endovascular aneurysm repair (EVAR) of the abdominal aortic and the common iliac artery (CIA) aneurysms. The patient underwent urgent surgery for TAAD treatment but died on the table due to intractable bleeding. We conclude that TAAD was likely unrelated to the initial EVAR procedure but rather to atherosclerosis, hypertension, and prior aortic valve replacement. Only a few cases in the literature report TAAD and total collapse of the abdominal aortic stent graft.
