title: [Diagnosis of microangiopathy by measurement of cutaneous circulation].
abstract: One method for measuring the cutaneous circulation is described: heat-conductibility, dependent on the variations of the circulation in the superficial layers of the skin, is measured. These variations are obtained by total temporary arterial occlusion, then by application of a vasodilatory cream. With this technique we can show not only arteriolar spasm, but also the organic occlusion of the cutaneous vessels in the case of arteriolar sclerosis (microangiopathy). The practical advantage of the measurement method is that it is possible to examine microangiopathological ulcerations, and those of mixed origin. The results make it possible to locate Martorell's hypertonic ulceration, for instance, or atherosclerotic ulcerations complicated by microangiopathy, or venous ulcers complicated by arteriolar sclerosis.
