## TL;DR

An 80-year-old woman with a large aortic aneurysm and breathing issues successfully underwent a minimally invasive repair using a special graft and local anesthesia.

## Contribution

A novel endovascular repair approach using a physician-modified inner-branched endograft under locoregional anesthesia for high-risk TAAA patients.

## Key findings

- Endovascular TAAA repair was successfully performed under locoregional anesthesia.
- The modified inner-branched endograft enabled treatment without major complications.
- This approach is viable for patients with severe comorbidities unsuitable for general anesthesia.

## Abstract

An 80-year-old female presented with a thoracoabdominal aortic aneurysm (TAAA) that had progressively enlarged to a diameter of 58 mm. She was scheduled for TAAA repair; however, she had a severe obstructive ventilatory disorder, which posed significant risks. Both open repair and general anesthesia were deemed to carry a high risk of respiratory complications. Consequently, an endovascular TAAA repair was performed using a physician-modified inner-branched endograft under locoregional anesthesia. This approach successfully treated the TAAA without any major complications. This strategy opens up the possibility of treating TAAA in patients with severe comorbidities that were previously challenging to treat.
