[Efficacy of endovascular prophylaxis of pulmonary thromboembolism].

The improvement of the treatment results and efficacy of the endovascular prophylaxis methods in patients at risk for pulmonary thromboembolism (PTHE) occurrence constitute the aim of the investigation. The work is based on retrospective analysis of the treatment results of 114 patients, to whom cava filter (CF) was implanted for the PTHE accidents prophylaxis. During hospital period after the CF implantation the PTHE reattacks were revealed in 4 patients, the CF embolism and thrombosis--in 10, the ascending thrombosis--in 8, the CF dislocation and migration--in 8. Late results of the CF implantation were studied in 54 patients in terms from 1 to 10 years. In 3 of them the symptomless perforation of vena cava inferior (VCI) wall was diagnosed with nonsignificant CF diversion, distal migration of CF with adequate preservation of antiembolic function--in 1, the thrombosis had occurred in 5 patients. The CF implantation into VCI is an effective method of endovascular prophylaxis of fatal PTHE. The high efficacy of CF "Osot" was evidenced, witnessing the expediency of its clinical application.
