暂时性动静脉瘘在血栓消融术治疗急性深静脉血栓形成中的作用

目的评估暂时性动静脉瘘(arteriovenousfistula,AVF)在Amplatz血栓消融器(Amplatzthrombectomydevice,ATD)治疗急性深静脉血栓形成(deepvenousthrombosis,DVT)中的作用。方法76例急性DVT患者采取ATD血栓消融术治疗,其中50例患者在介入治疗的基础上辅以暂时性AVF。结果1例术后第1天死于肺栓塞。72例术后第1天患肢肿胀明显消退、疼痛缓解。2例术后第7天对侧肢体继发DVT。暂时性AVF通畅率86%(43/50)。术后随访10～42个月,随访率90.7%(68/75)。59例肿胀消失,6例轻度下肢肿胀,1例继发下腔静脉血栓形成,2例死于其他疾病。结论暂时性AVF可提高取栓后静脉的血流量和加快其血流速度,提高静脉通畅率,是ATD的一个有益的辅助手段。

The role of temporary arteriovenous fistula in the treatment of acute deep venous thrombosis with Amplatz thrombectomy device

Objective To evaluate the role of temporary arteriovenous fistula(AVF) in the treatment of acute deep venous thrombosis(DVT) with Amplatz thrombectomy device(ATD). Method Seventy-six cases of acute DVT underwent mechanical thrombolysis with ATD, in which 50 cases received a temporary AVF after interventional therapy. Result One case died of pulmonary embolism. Ipsilateral limbs swelling subsided and pain alleviated in the remaining 72 cases since first post-operative day. Secondary contralateral DVT developed in 2 cases on the 7th post-operative day. The patency of temporary AVF was 86%(43/50). Sixty-eight cases (90.7%) were followed-up for 10~42 months post-operatively with limbs swelling completely subsided in 59 cases and ameliorated in 6 cases. Secondary inferior vena cava thrombosis developed in one case and 2 cases died of unrelated diseases. Conclusion Temporary AVF increases blood flow volume and blood velocity in the thrombectomized vein segment to improve the vein patency, hence is a valuable auxiliary means of ATD.
