Key result
Transcutaneous oxygen tension at incompetent perforators shows no significant difference vs. controls in chronic venous incompetence.
Why the study?
The combined measurement of transcutaneous oxygen tension and capillaroscopic imaging was applied to study skin capillaries in patients with chronic venous incompetence to gain pathophysiologic insights.
Cross-Sectional (n=17)
Absolute Event Rate: 47.7% vs 56.8%
p-value: p=NS
Simultaneous measurement of transcutaneous oxygen tension and videomicroscopy provides objective pathophysiologic insights into microcirculatory changes and skin ulcer development in chronic venous incompetence.

Normal tcPO2 at incompetent perforating veins without trophic changes does not support early hypoxia; hypothesis-generating for microcirculatory mechanisms in chronic venous disease.
Uk et al. (1984) conducted a cross-sectional in Chronic venous incompetence (n=17). Transcutaneous oxygen tension and videomicroscopy measurement vs. Control subjects was evaluated on Mean transcutaneous oxygen tension (tcPO2) at the site of incompetent perforating veins of the ankle without major trophic changes (p=NS). In patients with chronic venous incompetence, mean transcutaneous oxygen tension at incompetent perforating veins was 47.7 mm Hg, not significantly different from control subjects (56.8 mm Hg).
