Abstract
Transcutaneous [tc] pO2 [partial pressure] measurement by polarography is a non-invasive method already used in internal medicine and angiology. It was employed in patients suffering from chronic lower limb ulcerations of various origins. Marked hypoxia was found in venous ulcers without arterial occlusive disease (tc pO2 = 19.6 .+-. 16.9 mm Hg; mean value .+-. 1 SD). Tc pO2 was in the normal range in patients suffering from cryoglobulinemia (68.5 .+-. 10.5 mm Hg), but very low in hypertensive ulcers (0.7 .+-. 0.9 mm Hg) and in patients suffering from arterial occlusive disease (8.9 .+-. 11.8 mm Hg). Local hypoxia constitutes an important feature of many kinds of ulcers even when venous disease is the primary cause.
