Aim: The aim of this study was to evaluate the dynamics of the recanalization process (spontaneous fibrinolysis) in completely occlusive deep venous thrombosis (DVT) using duplex ultrasound examination and to investigate the influence of different factors on the evolution of thrombus regression.
Methods: This longitudinal prospective study was done with 74 consecutive patients with completely occlusive acute multilevel DVT, confirmed by echo duplex scan after 1, 3, 6, and 12 months. At each re-evaluation, the degree and the type of recanalization were determined.
The efficacy of dextran therapy in forty patients with chronic occlusive arterial disease (twelve with Buerger's disease and twenty-eight with atherosclerosis obliterans) was studied by repeated measurements of the following hemodynamic parameters;: the relative walking distance (RWD), the absolute walking distance (AWD), the oscillometric index (OI), the perfusion pressure of the affected limb (PP) and the Doppler index (DI) - the last two being determined by using an ultrasound technique. The hemodynamic improvements secondary to dextran therapy were demonstrated by the increase of RWD (from 115.3 m to 235.
