Preoperative Evaluation of Patients with Peripheral Vascular Disease

Abstract

Coronary artery disease is the leading cause of death after revascularization procedures for abdominal aortic aneurysms and peripheral vascular disease. Late survival after vascular procedures is substantially reduced, largely by the high incidence of subsequent cardiac events. At the Lahey Clinic, it is not our practice to perform routine coronary angiography before elective revascularization. Thallium myocardial perfusion imaging should be performed in all patients before operation. Abnormal results on thallium exercise scanning showing multiple perfusion abnormalities or lung uptake at peak exercise identify patients who are candidates for preoperative cardiac catheterization. When severe correctable coronary artery disease is identified, these patients should be considered for coronary artery bypass surgery before vascular operation.
