title: The evolution of carotid and coronary artery disease after operation for carotid stenosis.
abstract: We followed 278 consecutive patients undergoing carotid artery surgery between January 1985 and December 1989 using a computerized surveillance program file with automatic carotid and coronary artery follow-up investigations every six months. Combined postoperative neurologic mortality and morbidity was 1.7%. During the mean follow-up period of 30 months, 10 patients died, four due to myocardial infarction. Actuarial rates of survival and freedom from cerebral vascular accidents at 36 months were 94% and 95.8%, respectively. No fatalities due to cerebral vascular accidents occurred during follow-up. Eleven patients had myocardial infarction, an actuarial rate of 6% at 36 months; 18 patients experienced angina pectoris, while seven sustained silent electrical myocardial ischemia. Findings on myocardial angioscintiscans and coronary artery arteriograms led to four aortocoronary bypasses and seven percutaneous coronary artery dilatations. Duplex scanning documented three asymptomatic carotid restenoses of > or = 80%, which were operated upon, and 32 contralateral carotid artery stenoses ranging between 80% and 99%, 24 of which were asymptomatic. Twenty-eight patients underwent secondary contralateral carotid artery revascularization. No one with contralateral carotid artery stenosis < 80% experienced a carotid artery ischemic event. These results clearly show the value of cardiac and neurologic surveillance of patients operated on for carotid artery stenosis.
