# A novel technique for H-shaped reinforcement of double-barreled aorta in surgical treatment of chronic aortic dissection

## TL;DR

A new surgical technique using an H-shaped graft is described to safely reinforce the aorta in chronic aortic dissection treatment.

## Contribution

The novel H-shaped graft technique reinforces both aortic lumens to prevent anastomotic complications.

## Key findings

- An H-shaped graft was successfully sutured to both aortic lumens and the intimal flap.
- This technique may prevent complications like pseudoaneurysms at the anastomosis site.

## Abstract

Anastomosis of the prosthetic graft to the double-barreled aorta with intimal flap fenestration is a useful technique in surgery for chronic aortic dissection. Conversely, anastomosis to the false lumen's outer wall is prone to complications such as pseudoaneurysms, but little is known about the technique of reinforcing the double-barreled aorta. In this report, we describe a surgical case of chronic aortic dissection in which an H-shaped prosthetic graft was sutured to both aortic lumens, including the intimal flap, to prevent complications at the anastomosis site.
