下腔静脉滤器常被用于下肢深静脉血栓患者以预防肺栓塞。我科接收1例下肢深静脉血栓患者滤器置入术后继发下腔静脉血栓。溶栓成功后,为避免滤器长期置入而引起的并发症,采取经颈股静脉双向入路成功取出植入40 d后的永久滤器(Cordis TrapEase)1枚,现报道如下。 Inferior vena cava filters are often used in patients with deep vein thrombosis to prevent pulmonary embolism. Our department received 1 case of deep venous thrombosis in patients with postoperative secondary filter inserted inferior vena cava thrombus. After successful thrombolysis, in order to avoid the complications caused by long-term filter insertion, a permanent filter (Cordis TrapEase) after 40 days of implants was successfully taken through the bi-directional approach of the cervical femoral vein and is reported as follows.
