[Surgical indications in the phlebopathic patient. The role of air plethysmography].
A previous history of deep venous thrombosis (DVT) must be carefully evaluated in every patient affected by chronic venous insufficiency (CVI); the assessment of deep venous system patency is the goal of preoperative diagnosis. Air plethysmography examination allows an outpatient noninvasive testing of calf pump function and deep venous outflow. The authors report the results of a study on 37 patients (40 limbs) with a previous history of DVT, suffering from CVI; in 18 limbs air plethysmography showed a marked increase of calf volume on test exercise, suggesting residual venous obstruction. The authors believe that air plethysmography examination is mandatory before operation in patients with a previous history of DVT.
