Long-term Results of Elective Open Repair of Abdominal Aortic Aneurysms: 10 Years of Experience at the Tri-Service General Hospital in Taiwan
並列摘要
Background: Because endoluminal stenting may reduce early mortality and morbidity rates relating to treatment of abdominal aortic aneurysms (AAAs), it is becoming increasingly important to know the long-term survival and quality of life of patients after open repair for an AAA. This report describes our long-term results of conventional elective open surgical repair of AAAs and discusses various aspects of the surgical strategy to improve long-term survival after the operation. Methods: We retrospectively reviewed the charts of 53 patients (46 men and seven women) with an AAA who underwent open surgical repair at the Tri-Service General Hospital, Taiwan, from 1996 through 2005. The demographic characteristics, operative data, postoperative results, and long-term outcomes of patients were recorded and analyzed. Results: The mean age was 66.5 years (range, 21-88 years). Associated morbidities were hypertension (66.0%), coronary artery disease (51%), peripheral arterial occlusive disease (24.5%), diabetes mellitus (18.9%), stroke (17.0%), and respiratory disease (17.0%). The operative mortality rate was 6.8%. The cumulative survival rates at one year, three years, and five years were 90.6%, 67.5%, and 55.4%, respectively. The long-term death rate involved death from coronary artery disease in eight patients, septic shock in four patients, cancer in four patients, cerebrovascular disease in three patients, and ascending aortic dissection in one patient. No anastomotic pseudoaneurysm or aortoenteric fistula was found in the surviving patients. Conclusions: Although conventional open surgery for graft implantation has been challenged recently by endoluminal stenting via the transfemoral approach, open repair of an AAA can be done in elective cases with acceptable morbidity and mortality rates. To improve long-term survival after the aneurysm operation, preoperative coronary artery screening, careful follow-up, and repeated evaluation should be considered to prevent late cardiovascular complications.
