Abstract
Abnormal levels of transcutaneous tissue oxygen tension (TcPO2) have been reported in venous disease but the most appropriate application of the technique to the study of venous disease is not clear. Patients with mild (superificial varicosities) and severe venous disease (ulcers and/or skin changes) and normal controls were studied. Four variables derived by measurement of TcPO2 were used for comparison between groups. The peak postischaemic response was reduced markedly in patients with severe venous disease and may be the most appropriate way of applying TcPO2 measurements to investigation of venous disease. The findings support the theory that a diffusion block to oxygen exists in severe venous disease.
