目的评价两种可回收式滤器在静脉血栓-栓塞病变介入治疗中的有效性及安全性。方法 100例急性和亚急性肢体深静脉血栓形成(DVT)患者(其中肺栓塞62例)接受经导管局部溶栓的同时,置入可回收式滤器(OptEase72例,Tulip28例)。对局部溶栓效果较好者考虑进行滤器回收。结果两种滤器均成功置入下腔静脉(98例)和上腔静脉(2例),无滤器移位。除1例滤器回收失败外,24枚滤器置入后7～50天(平均18.0天)经颈静脉(Tulip滤器15例)或经股静脉(OptEase滤器9例)回收成功。患者住院期间均未发生肺栓塞加重。10例穿刺部位出现较大血肿,2例发生脑出血,4例出现肉眼血尿。结论可回收式滤器可安全用于DVT的介入治疗,防止致命性肺栓塞的发生;回收简便、安全。
Objective To evaluate the effectiveness and safety of two recoverable filters in the interventional treatment of venous thromboembolism. Methods 100 cases of acute and sub-acute limb deep venous thrombosis (DVT) patients (62 cases of pulmonary embolism) underwent transcatheter thrombolysis while placed in reusable filter (OptEase 72 cases, Tulip 28 cases). For local thrombolysis better consider filter recovery. Results Both filters were successfully placed in inferior vena cava (98 cases) and superior vena cava (2 cases) without filter displacement. Except for the failure of one filter recovery, 24 filters were successfully collected via the jugular vein (15 cases of Tulip filter) or the femoral vein (9 cases of OptEase filter) after 7 to 50 days (mean 18.0 days) after implantation. Patients during hospitalization were not exacerbated pulmonary embolism. 10 cases of puncture site larger hematoma, cerebral hemorrhage occurred in 2 cases, 4 cases of gross hematuria. Conclusion Recyclable filter can be safely used in DVT interventional treatment to prevent the occurrence of fatal pulmonary embolism; recovery is simple and safe.
