Real-time B-mode ultrasonography of the femoral arteries: comparison to contrast arteriography.
Forty-five patients with symptomatic peripheral vascular disease were studied with a high-resolution, real-time B-mode echo imaging system for visualization of the femoral arteries. Common femoral and superficial femoral arteries were visualized in over 88 per cent of cases, whereas the profunda femoris artery was demonstrated in only about one-third of cases. Stenotic lesions (+ or - 20% of arteriographic assessment) were identified in two-thirds of cases. Prostheses and grafts in the proximal and medial cases. Prostheses and grafts in the proximal and medial thigh were well visualized. Anatomic information provided by B-mode imaging will complement functional assessments of lower extremity vascular insufficiency.
