[Experience in 237 patients undergoing infrarenal abdominal aortic aneurysm operations]

To improve the safety of infrarenal abdominal aortic aneurysm (AAA) repair.

237 patients underwent infrarenal abdominal aorta aneurysm operations from January 1, 1960 to December 1996. Retroperitoneal approach was for AAA operation. The new methods for control of the "neck" of aneurysm, aneurysmectomy and "parachute" of proximal aorta anastomosis were applied.

The danger of AAA repair obviously decreased and operation time shortened to 2-3 hours. The perioperative mortality was 3.8% and the five-year survival 74.4%.

The improvement of surgical and anesthetic techniques made AAA resection rapid and safe.
