Intervention combined surgery for the treatment of acute iliofemoral vein thrombosis

Abstract

Objective To compare two treatment methods for acute iliofemoral vein thrombosis:c atheter-directed pharmacomechanical thrombolysis (CDPT,47 cases) and intervention combined surgicaltherapy( IST,14 cases).Methods This study includes 61 patients of acute iliofemoral vein thrombosis treated by CDPT or IST.All discharged cases were followed up by telephone for a period of 14 -37 months.Results Among the 61 patients (64 extremities),47 (forty-seven extremities) treated by CDPT,and 14 cases (seventeen extremities) treated by IST.The IST group included three patients of bilateral iliofemoral vein thrombosis,five patients on postoperative status within one month,and three patients in which the iliofemoral vein was not accessible.When discharged from hospital,the effective rate of edema relief is 93.6％ in CDPT group while that is 94.1％ in IST group; Melena occurred in one patient of CDPT group and incision hematoma occurred in one patient of IST group.According to the results of 14 -37 months follow-up,the effective rate of edema relief is 85.0％ in CDPT group while that is 85.7％ in IST group ( x2 =0.004 and the P =0.948).Calf pigmentation occurred in only one patient of CDPT group.The patency rate of vein by BUS examination is 52.6％ in CDPT group while that is 84.6％ in IST group x2 =4.157,P =0.041 ).Conclusions Comparing with CDPT group,IST group has the similar effective rate of edema relief,but has higher patency rate of iliofemoral vein.In case of bilateral acute iliofemoral vein thrombosis,in patients in whom thrombolysis is contraindicated,or when the iliofemoral vein is not accessible,IST is the treatment of choice for acute iliofemoral vein thrombosis.
