## TL;DR

A 53-year-old woman with a rare aortic condition underwent successful surgery to replace her aorta, with a favorable recovery and no complications.

## Contribution

This case report presents a rare anatomical variant and successful surgical management of a Crawford II thoracoabdominal aneurysm.

## Key findings

- The patient's thoracoabdominal aortic aneurysm was successfully excluded with complete thrombosis.
- The right-sided descending aorta is a rare malformation successfully managed with exclusion technique.
- Postoperative recovery was favorable with no retrograde flow from intercostal arteries.

## Abstract

A 53-year-old woman was diagnosed with a Crawford II thoracoabdominal aortic aneurysm involving the right-sided descending aorta. The patient underwent aortic replacement via a thoracoabdominal approach. The right-sided descending thoracic aortic aneurysm was excluded. The patient had a favorable postoperative course. The excluded thoracic aneurysm had completely thrombosed without intercostal inflow. The right-sided descending aorta is a rare malformation. The exclusion technique was appropriate because there was no retrograde flow from the intercostal arteries and the Adamkiewicz artery originated from the lumbar region.
