[Implications of preoperative angiography and coronary artery bypass grafting for patients with combined coronary artery and great vessels diseases].

Preoperative coronary angiography showed that the significant coronary artery disease (CAD) was present in 47% of patients with thoracic aortic aneurysm (TAA), abdominal aortic aneurysm (AAA), or aortoiliac occlusive disease (A.I). Fifty-seven patients underwent the both coronary artery and great vessel diseases on the simultaneous or sequential stage. As CAD, 13 patients had one vessel disease (VD), 18 had two-VD, 26 had three-VD and 4 of them had left main trunk lesions. As great vessel diseases, 23 patients had A-I, 20 had AAA, 8 had TAA, 5 had TAA+AAA, and 1 had TAA+A-I. There were 4 early deaths (7%) in 57 patients, and 4 (3%) in total 120 coronary and great vessel's operative procedures. The 5-year survival rates were 57.4 +/- 15.5% for TAA, 87.1 +/- 8.5% for AAA and 63.9 +/- 11.1% for A-I, which were not significantly different from those of patients without CAD, respectively except for TAA. The present data suggest that preoperative coronary angiography and CABG in the selected patients may have the beneficial effects on survival and quality of life.
