[Surgical treatment of coexistent aortic, peripheral vascular and coronary disease].

To determine the priority of the surgical treatment of coexistent aortic and coronary disease (CAD), we reviewed 19 cases of aortic aneurysm combined with severe coronary lesions who underwent operation from Jan, 1984 to Aug, 1989. There were 15 cases of abdominal and 4 cases of thoracic aneurysm. All patients had graft replacement for the aneurysm and 12 patients had elective aortocoronary bypass surgery (CABG), one had percutaneous transluminal coronary angioplasty and 6 received medical treatment for CAD. In 6 cases, CABG preceded abdominal aneurysm operation. In 3 cases of ascending thoracic aneurysm, simultaneous coronary and aortic operation were performed. There were no early and late operative death. In an attempt to reduce perioperative myocardial infarction which is one of the most frequent complications of aneurysmal operation, we performed routine coronary angiogram before operation. In 104 patients considered for elective aortic and peripheral vascular disease, coronary angiogram were performed. The incidence of coexistent coronary artery disease in peripheral vascular and aortic disease were 46.1%. The incidence of multiple vessel CAD in patients with aortic and peripheral disease were high. Our surgical strategy for coexistent aortic, peripheral vascular and coronary disease is basically staged operation and simultaneous operation are performed only in ascending and proximal arch aneurysm.
