[Action of elastic compression on valvular closing time].
The study was carried out in ten patients with venous insufficiency of limbs verified by clinical standards, photopletismography and descending venogram witch, previous venous stasis ulcer and branquial/ankle doppler index greater than 0.9. The valvular closing time (VCT) was measured with Duplex scanning, at the level of popliteal vein bellow de lesser safenous vein entrance. The ten patients showed an initial VCT greater than 0.5 sec, with the utilization of the elastic compression and new measurement of VCT, seven showed a normalization of VCT (valves lower than 0.5 sec). The elastic compression of limbs is efficient in reducing the venous reflux and it could be evaluated individually with a non invasive test--The Duplex scanning.
