Diagnosis of peripheral occlusive disease: comparison of clinical evaluation and noninvasive laboratory

One hundred and two patients with peripheral vascular disease were evaluated by the attending surgeon, residents and students, and the vascular laboratory prior to arteriography to test their ability to make a correct anatomic diagnosis. The attending surgeons made a correct anatomic diagnosis in 98 patients and were at least partially correct in the other four. Surgical housestaff and students were 62% totally correct, 35% partially correct, and 3% totally wrong. The vascular laboratory results were almost identical with the attending surgeon, but two patients could not be evaluated because of calcified arteries. The operation that was eventually performed was suggested initially by the laboratory and the attending surgeon in 98% of the patients.
