The aim of this study was to estimate the results of abdominal aortic aneurysm (AAA) repair with or without coronary artery disease (CAD), retospectively. We studied the incidence of associated CAD among 47 consecutive patients operated upon for AAA, excluding ruptured aneurysms. The screening of CAD was routinely performed by coronary angiography. More than 50% luminal stenosis of the major coronary artery was judged positive for CAD. Twenty-five of the 47 patients (53%) had CAD of 25 patients, 14 patients were subjected to pharmacotherapy, and 11 were indicated coronary revasculization. Nine of those patients underwent successful PTCA prior to surgery. The remaining two patients were considered to be unsuitable for PTCA and underwent coronary bypass grafting before AAA repair. There was no operative mortality or perioperative myocardiac infarction during and after the repair of AAA. This study seggests that AAA repair with CAD could be performed saflely by means of the detailed preoperative evalution and that PTCA or CABG should be approached aggressively in cases with CAD prior to AAA repair.
