Operative Results of One Hundred and Twenty Cases of Abdominal Aortic Aneurysms and Surgical Strategy for Cases Requiring Coronary Revascularization / 日本心臓血管外科学会雑誌

ABSTRACT

Between 1970 and October, 1992, 120 cases of abdominal aortic aneurysms (AAA) were treated for surgical repair. Thirteen of these cases (11%) were performed with simultaneous repair for coexistent visceral vascular diseases and other intestinal organ diseases. Another 9 patients (7.5%) were treated with coronary revascularization for combined ischemic heart disease. Six of these cases received both operations during the same hospital stay. Our surgical strategy for coexistent AAA and ischemic coronary artery disease is basically a staged operation. Coronary revascularization should precede AAA repair. Operative mortality was 1.1 percent for elective AAA repair. Long-term survival was 78% for elective surgery with a mean follow-up of 51 months, and 52% for emergency surgery with a mean follow-up of 46 months. Major risks for late death were malignant neoplasms and ischemic coronary artery disease. Survival rate of the 9 patients with successful concomitant coronary revascularization and AAA repair was 89% after 51 months of mean follow-up. We conclude that re-evaluation for coexistent ischemic heart disease is the most important point for management before and after AAA repair.
