Clinical and morphological aspects of Buerger's disease.

Background: Thirty-five patients with TAO and 35 with ASO have been studied. To determine differences between these two arterial diseases, we used clinical criteria, arteriographic and morphological methods. The peripheral (below the bifurcation of the popliteal artery) angiographic changes were found in TAO with 94% sensitivity, 94% specificity and with 96% of positive predictive value.
