Abstract:
Coronary angiography and brain computed tomography were preoperatively performed to evaluate the clinical condition of coronary artery disease and cerebrovascular disease in 101 patients (mean age, 68.4 years) with revascularization for arteriosclerosis obliterans. Eighty patients had hypertension, 12 had diabetes, and 26 had hyperlipidemia. Seventy-one patients (70.3%) had coronary stenosis. Significant stenoses in major coronary artery branches were confirmed in 35 patients, including 13 patients with old myocardial infarction. Coronary artery bypass grafting and percutaneous coronary angioplasty were performed in 2 and 7 patients with critical stenosis, respectively. Of 57 patients, who underwent brain computed tomography, abnormalities were found in 52 patients (91.2%), including cortical infarction in 9, lacunar infarction in 35, and leukoaraiosis in 27 patients. During the follow-up period 13 patients died (including 3 cases of myocardial infarction and 3 cases of stroke). Actuarial survival rate at 5 years was 80.4%. The influence of ischemic heart disease and cerebrovascular disease on early and late mortality after surgical reconstruction for peripheral occlusive vascular disease is significant. Using visual diagnostic techniques, such as coronary angiography and brain computed tomography, long term survivor should be closely observed for multiple arteriosclerotic vascular diseases.
