AIMS: The occurrence of inferior vena cava (IVC) filter thrombosis has been reported, however, the optimal treatment of IVC thrombosis has not been established yet. The aim of this study was to assess the results of catheter-directed thrombolysis(CDT) combined with aspiration thrombectomy(AT) in the treatment for IVC filter thrombosis.
METHODS:A total of 35consecutive patients received endovascular treatment with CDT alone or CDT with AT for IVC filter thrombosis at second affiliated hospital of Soochow University from May 2009 to May 2014 were included in this study. The procedure, complications and clinical outcome between these two group were retrospectively reviewed.
RESULTS: The mean age of patients was 44.7±15.8 years (range: 17-74 years).The patients were consisted of 21 males and 14 females. CDT alone and CDT with AT were performed in 16 and 19 patients, respectively. The mean procedural time of CDT alone group was longer than CDT with AT group (99.5±51.4 h vs 64.9±35.9 h, p<0.05) and dose of urokinase used during the procedure was significantly decreased in CDT with AT group (2.1±1.1million IU vs 1.5±0.6 million IU, p<0.05). Besides, total number of complications in CDT with AT group was smaller than in CDT alone group(9 cases vs 4 cases, P<0.05).
CONCLUSIONS: Our results confirmed that CDT with AT was a safe and effective method in the treatment of acute IVC filter thrombosis. Compared with CDT alone, it was more excellent for less thrombolysis time and urokinase dose. In addition, it may decrease the occurrence of complications.
