The authors present in the article the results of studying quality of life of patients at various terms after endured iliofemoral phlebothrombosis (from 0 to 60 months), who, depending upon embologenicity of the thrombus in order to prevent pulmonary embolism, were either subjected to implantation of a cava filter or not. The patients were subdivided into two groups: the study group (129 subjects) included those presenting with acute or recently endured iliofemoral phlebothrombosis and a cava filter implanted at various time having elapsed after. The comparison group consisted of 96 patients with endured iliofemoral phlebothrombosis within the same terms and having received conservative treatment without implantation of a cava filter. Quality of life was assessed by two questionnaires, i.e. MOS-SF-36 and CIVIQ. The authors concluded that the patients with endured iliofemoral phlebothrombosis without implantation of a cava filter in the anamnesis demonstrated slightly better measures of quality of life.
