After-exercise thermography compared to strain-gauge plethysmography and venous pressure measurements to detect deep venous insufficiency.

After-exercise thermography (AET) has been claimed to be a means of detecting deep venous insufficiency. The question was studied in 167 patients four to five years after major surgery. The tests af follow-up included AET, strain-gauge plethysmography and venous pressure measurements in addition to clinical examination and a questionnaire concerning history, symptoms etc. No correlation was found between abnormal AET and objective manifestations of deep venous insufficiency.
