# Innovative Therapeutic Strategy for Complicated Thoracoabdominal Aortic Aneurysms: Dimension Reduction

## TL;DR

A new hybrid surgical approach using a customized graft is presented for treating complex aortic aneurysms with potentially lower risk.

## Contribution

A staged hybrid repair technique using a customized 3-bifurcated graft is introduced for complicated thoracoabdominal aortic aneurysms.

## Key findings

- Staged hybrid repair with a customized graft was successfully used for a type II TAAA.
- The approach demonstrates the concept of dimensionality reduction in treating complex aneurysms.
- This method offers a promising alternative to traditional high-risk open surgery.

## Abstract

Open surgical repair of complicated thoracoabdominal aortic aneurysms (TAAAs) has a high mortality rate, leading to an increased appreciation for staged hybrid repair. We report a case of abdominal aneurysm replacement with an artificial Y graft and total visceral aortic debranching through retrograde artery revascularization with a customized 3-bifurcated graft in a hybrid surgery for type II TAAA. Staged hybrid repair epitomizes the application of a dimensionality reduction treatment concept, offering considerable promise for addressing complicated TAAAs.
