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

Abstract

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 at 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.

Key Words:

• strain-gauge plethysmography
• thermography
• venous insufficiency
• venous pressure
