ABSTRACT
Correlation of the plethysmographic and arteriographic evidence of obstructive arterial disease .as to (1) the anatomic site of the arterial lesion and the degree of obstruction, and (2) the extent of collateral circulation was possible in 51 of the 53 patients in this survey. In 44 of these patients (86 per cent), the plethysmogram was considered an excellent tool for indicating the site and the severity of the lesion, but the extent of the collateral circulation was defined accurately in only 23 (45 per cent). With arteriography, the lesion could be located precisely at the aorta, or at the iliac, femoral or popliteal levels. When 103 plethysmographic studies of the limbs of these 53 patients including measurement of ankle to arm pressure, hyperemia response and inspection of pulse contours were considered, these parameters revealed that clinically symptomatic patients with plethysmographic pulse contours indicating moderate to severe arterial obstruction and pressure deficits of more than 10 mm Hg were candidates for arteriography. (Arteriography would detect peripheral vascular abnormalities in these patients.) The wide diversity between hyperemia response and arteriographic findings, however, seemed to limit the usefulness of this technique. Hyperemia response probably is dependent on the local distensibility of the arteriolar bed or on an exaggerated sympathetic response in a patient with significant obstructive arterial disease, and the test does not reflect the true magnitude of the obstruction.
