Value of cuff occlusion pressures in assessment of peripheral vascular disease.

Cuff occlusion pressures using the ultrasonic Doppler machine were recorded in 30 normal legs and in 90 legs with peripheral vascular disease. With this technique it was possible to show obstructions to the circulation above and below the inguinal ligament.

Experimental venous lesions of the colon.

This experimental work has shown that structural changes in the colon may be produced following inferior mesenteric vein thrombosis. Whilst there are certain radiological similarities, sigmoidoscopic appearances and histological studies show that the pathogenesis of venous lesions differs from that of arterial lesions. The possible relationship of these experiments to clinical lesions is discussed.
