The aims of the study were development and clinical approbation of the method of local catheter thrombolysis in patients with deep vein thrombosis. The immediate and long-term results of the use of the new endovascular technology in nine patients with iliofemoral deep vein thrombosis were studied. Comparative analysis of treatment outcomes with a group of patients who received monotherapy with vitamin K antagonists confirmed the safety and efficacy of catheter thrombolysis in regard to hemorrhagic complications, the incidence of post-thrombotic disease and the degree of its severity.
