# Midline abdominal incision with left transverse extension for type IV thoracoabdominal aortic aneurysm repair

## TL;DR

A new surgical approach for aortic aneurysm repair is described, offering good results with fewer complications.

## Contribution

A novel midline abdominal incision technique for type IV thoracoabdominal aortic aneurysm repair is introduced.

## Key findings

- Six patients successfully underwent the procedure with no mortality and all being discharged home.
- The approach allowed for good surgical exposure and concurrent abdominal procedures.
- Respiratory complications were minimized compared to traditional methods.

## Abstract

We describe a technique for repairing Crawford type IV thoracoabdominal aortic aneurysms using a midline abdominal incision with left transverse extension, performed in the supine position without thoracotomy. Six patients (median age, 73 years) underwent this approach for true aneurysms, chronic dissection, or aortoduodenal fistula. Aortic reconstruction was performed with four-branched or bifurcated grafts under selective visceral perfusion. All patients were discharged home; one required reoperation for bleeding, and one developed an abdominal wall incisional hernia. This approach provided sufficient exposure for proximal and distal anastomoses and facilitated concurrent abdominal procedures while minimizing respiratory complications.
