目的： 评估股深静脉血栓清除在急性下肢深静脉血栓形成（DVT）腔内治疗中的安全性与有效性。方法： 回顾性分析2022年1月至2023年9月于我院对股深静脉血栓行经皮机械血栓清除（PMT）的急性下肢DVT病人临床资料。分析术后12个月的髂股静脉一期通畅率和血栓形成后综合征（PTS）发生率。结果： 共22例纳入研究，所有病人均对股深静脉血栓行PMT。其中5例通过对侧股总静脉“翻山”入路，17例通过对侧股总静脉“翻山”联合患侧深静脉入路。术后12个月髂股静脉的一期通畅率为90.9%（20/22），PTS的发生率为9.1%（2/22）。结论： 急性下肢DVT行腔内治疗的病人，对股深静脉血栓行PMT治疗安全有效，可获得良好的髂股静脉一期通畅率，且PTS的发生率低。

Objective To evaluate the safety and efficacy of profunda femoral vein thrombosis clearance in endovascular treatment of acute lower extremity deep venous thrombosis (DVT). Methods From January 2022 to September 2023, clinical data of acute lower extremity DVT patients who underwent percutaneous mechanical thrombectomy (PMT) for profunda femoral vein thrombosis were retrospectively analyzed. The 12-month primary patency rate of iliofemoral vein and incidence of post-thrombotic syndrome(PTS) were analyzed. Results Twenty-two patients were included in the study, and all patients underwent PMT for profunda femoral vein thrombosis. Five patients were treated through the contralateral common femoral vein via crossover approach, and 17 patients were treated through the contralateral common femoral vein combined with the ipsilateral deep vein approach. The 12-month primary patency rate of iliofemoral vein was 90.9% (20/22), and the incidence of PTS was 9.1% (2/22). Conclusions For patients with acute lower extremity DVT undergoing endovascular treatment, PMT for profunda femoral vein thrombosis is safe and effective, achieving good primary patency of iliofemoral vein and low incidence of PTS.
