Twenty-one patients who underwent a four-compartment fasciotomy between January 1, 1986, and December 31, 1987, were revisited with respect to venous calf-pump function 32 to 56 months (mean, 46.2 months) after fasciotomy. Enrollment criteria consisted of an intact motor innervation, palpable pedal pulses, the absence of venous hypertension, and deep venous thrombosis before and during the treatment requiring fasciotomy and unimpaired ankle and knee joint function. None of the patients showed signs of chronic venous hypertension at assessment. Ambulatory strain-gauge plethysmography revealed no significant difference in recovery time and refilling volume values between the two limbs of each patient (p > 0.1) and between limbs in which fasciotomy was performed and those of normal subjects (p > 0.1). Color flow duplex scanning revealed patent popliteal veins with normal respiration-induced phasic flow pattern and absent reflux in all patients. All visible calf veins were patent, compressible, and without morphologic alterations. The fasciotomy wound was closed by delayed skin suture (the fascia remaining divided) in 48% and by skin grafts of the lateral incision in 52% of the patients, without significant difference in recovery time and refilling volume values (p > 0.1) at assessment. Fasciotomy does not lead to venous calf-pump dysfunction, irrespective of whether the wound is closed by delayed suture or skin grafts.
