The ambulatory venous pressure (AVP) was measured by inserting a needle in a vein on the foot; the presence of reflux in the popliteal vein was determined by a directional Doppler ultrasonic blood velocity detector. All patients had ascending venography. The results suggest that the most important factor in determining the AVP and ulceration in postthrombotic limbs is the condition of the popliteal valves. Ulceration does not occur even in the presence of occlusion if the popliteal valves are competent. The extent of DVT and recanalization or the failure of recanalization is of secondary importance.(Arch Surg 114:1304-1306, 1979) SN - 0004-0010 M3 - doi: 10.1001/archsurg.1979.01370350106012 UR - http://dx.doi.org/10.1001/archsurg.1979.01370350106012 ER -
