[Diagnosis of occlusions of major arteries of the lower extremities by transcutaneous measuring of oxygen tension].

A noninvasive criterion of occlusions of the lower limb arteries was elaborated from the results of transcutaneous measurement of oxygen tension (TmO2) during treading on a treadmill. The authors examined 44 patients with angiographically diagnosed affection of the vessels and 35 patients of the control group. Fall of TmO2 during a load by 20 mm Hg of relative rest was found to be a reliable criterion of occlusion marked by high sensitivity, specificity, and prognostic value.
