Laparoscopy-Assisted Abdominal Aortic Aneurysm Repair

First Case Reports From Japan

抄録

Laparoscopy-assisted abdominal aortic aneurysm (AAA) repair consists of retroperitoneal laparoscopic dissection of the AAA and graft replacement performed via a mini-laparotomy. Two patients with infrarenal AAA underwent successful straight graft replacement using this hybrid approach. The retroperitoneal space was bluntly dissected under carbon dioxide pneumoretroperitoneum and further dissection was performed laparoscopically. This enabled proximal and distal control of the aneurysm, and occlusion of the lumbar arteries and the inferior mesenteric artery with hemoclips. A 7 cm mini-laparotomy was sufficient for the straight graft replacement. Laparoscopy-assisted repair is a less invasive technique for the treatment of AAA and can be regarded as the initial step towards totally endoscopic repair. (Circ J 2003; 67: 99 -101)
