[Oxygen pressure values in the ischemic muscle tissue of patients with occlusive arterial diseases (author's transl)].

The local oxygen pressure of muscle tissue was measured in 10 patients with occlusive atherosclerosis and in 9 healthy volunteers using a micro-Pt-electrode. In 3 cases, the muscular pO2 values of an ischemic leg were compared to the non-ischemic leg of the same patient. In both groups, there was a statistically significant difference in the oxygen pressure of the muscle tissue in normal legs of volunteers as compared to the ischemic legs. Measurements of the local oxygen pressure in the muscle enables us to have a quantitative measure for the ischemic situtation. It is a useful diagnostic method in patients suffering from ischemic claudication and seems to be an objective criterium of therapeutical methods.
