Abstract: 【Abstract】 Objective To investigate the correlation between inferior versa cava filter (IVCF) implantation and recurrence of deep venous thrombosis(DVT ) of lower limb. Methods A total of selected 211 cases with DVT of lower limb, who were treated in our hospital from Jan. 2007 to Jan. 2009, were divided into recurrent group and non-recurrent group according to their outcome. Eleven possible relative factors, such as age, sex, type,ICVF implantation and so on, were compared between two groups. Results Multivariate logistic regression analysis revealed that ICVF implantation, no anticoagulant therapy, type, no elastic-stocking therapy were independent risk factors for the recurrence of DVT ( P<0.05)，and the other factors were not associated with the recurrence of DVT ( P>0.05).Conclusion IVCF implantation is a important independent risk factor for recurrence of DVT. Anticoagulant therapy and elastic-stocking therapy will benefit to reduce the recurrence of DVT of lower limb.
