Purpose The morbidity associated with contrast-based diagnostics performed for preoperative evaluation prior to vascular intervention ranges from 1 to 21%. These complications range from minor hematomas to death. However, these exams are commonly felt to be a necessary step to completely evaluate the arterial tree before intervention is undertaken. Since this has varied from our experience, we reviewed our experience with repair of abdominal aortic aneurysms (AAAs), carotid endartectomy (CEA). and lower extremity revascularization performed without preoperative contrast studies. Materials and methods During the last 10 years, we have performed 184 elective AAA repairs with abdominal-pelvis CAT scan without intravenous contrast as a preoperative study. During this same period of time. 903 CEAs were performed in 810 patients based solely on duplex ultrasonography or in combination with magnetic resonance angiography in cases where duplex ultrasonography was inconclusive (53 cases). Finally, over the last 30 months, we have performed 485 revascularizations in the lower extremity based solely on duplex ultrasonography mapping. Direct visualization of all major arteries from the distal
