Case presentations with interesting echo findings on lower limb artery disease

Abstract

The frequency of arteriosclerosis obliterans (ASO) is increasing in Japan in association with an aging population and westernization of eating habits. The main purpose of lower limb artery echo is to diagnose ASO precisely. On the other hand, there are some rare cases that do not have typical ASO. In cases with very rare disease, lower limb artery echo should be done step by step as follows: differentiation from an arteriosclerosis-related lesion, exclusion of acute arterial disease, and anatomical and structural assessment of blood vessels. Furthermore, clinical information such as the status of lower limb skin or various patient complaints is very important to make a final diagnosis.
