Multicenter validation study of real-time (B-mode) ultrasound, arteriography, and pathologic examination.

The ability of high-resolution ultrasound, angiography, and pathologic examination of endarterectomy specimens to identify and quantitate atherosclerosis was compared in a five-center study. The carotid bifurcation in 900 patients was evaluated by angiography and ultrasound. In 216 cases, high-quality endarterectomy specimens were available for comparison with the preoperative images.

Identification of peripheral vascular disease with real-time ultrasonic imaging.

Real-time ultrasonic imaging can provide useful clinical information in subjects with peripheral vascular disease. This report outlines the technique of imaging the extracranial arterial system and arterial segments that supply the lower extremities. It describes our interpretation of the ultrasonic image as it relates to the pathology of fatty streaks, smooth and complex plaques, occlusions and thrombus formations.

Clinical sequelae in patients with asymptomatic carotid bruits.

Noninvasive vascular laboratory evaluations were performed on 163 patients who presented with asymptomatic carotid bruits. Of these, 57 patients were identified as having a solely transmitted murmur. The remaining 106 patients had carotid disease.
