Abstract:
Objective To evaluate the possibility of deep vein thrombosis defluvium of lower limb using ultrasonography to provide important reference for the implantation and retrieve of retrievable inferior vena cave (IVC ) filters.Methods Sixty-four patients who were diagnosed as lower limb deep vein thrombosis using ultrasonography were enrolled.Fourteen patients with critical values were allocated to high risk group,50 patients without critical value to low risk group.All the patients underwent inferior vena cava filter operation.Of all these patients,ultrosonography were performed once again before IVC filters were retrieved.Seventeen patients with broken thrombosis were allocated to unstable group,47 patients with stable thrombosis to stable group.Relationships between conditions of thrombosis and ultrasonography results were analysed.The conditions of thrombosis were recorded.The rates of thrombosis defluvium were compared.Results In high risk group,10 patients (71 .43%)had thrombosis.In low risk group,8 patients (16%)had thrombosis.There were significant differences in the rates of thrombosis defluvium beteen the high risk group and low risk group(P <0.05).In unstable group,12 patients (70.59%)had thrombosis.In stable group,6 patients (12.77%) had thrombosis,there were significant differences in the rates of thrombosis defluvium between the unstable group and stable group (P < 0.05 ).Conclusions Ultrasonography can be used to evaluate the possibility of lower extremity deep vein thrombosis defluvium which will guide the pratice of the retrievable inferior vena cava filter.
