Abstract:
During surgery for an abdominal aortic aneurysm, various problems can occur at the proximal anastomosis. Adequate exposure must be secured, and the proximal anastomosis must be sutured firmly. We have used a malleable U-shaped retractor to easily secure exposure of the proximal anastomosis. Despite recent advances in endovascular treatment, abdominal aortic aneurysm repair often requires open surgery. We describe our malleable U-shaped retractor technique, which is very easy and facilitates the creation of a secure proximal anastomosis.
