Abstract  

Objective: To evaluate the long-term efficacy of percutaneous mechanical thrombectomy (PMT) combined with stent implantation in treatment of acute iliofemoral vein thrombosis. Methods: Seventy patients with acute iliac vein thrombosis were treated with PMT combined stent implantation in Ningbo No.2 Hospital from November 2015 to November 2017. During the follow-up, the improvement of blood flow was evaluated, the occurrence of post-thrombotic syndrome was assessed by the Villalta rating scale, and the stent patency was examined with lower extremity ultrasound or angiography. Results: The blood flow was significantly improved after procedure in all 70 patients, including 62 cases (88.6%) of grade Ⅲ clearance, 5 cases (7.1%) of grade Ⅱ clearance, and 3 cases (4.3%) of grade Ⅰ clearance. No significant complications occurred during the treatment. The patients were followed up for (15.0±2.5) months. During the follow-up, 64 patients (91.4%) had unobstructed stents, and 9 patients (12.8%) had post-thrombotic syndrome. Conclusion: PMT combined with stent implantation is effective in the treatment of acute iliac vein thrombosis with a high medium-and long-term stent patency rate.

经皮机械血栓清除联合支架植入治疗急性髂股静脉血栓形成患者中远期疗效评估

目的: 评估经皮机械血栓清除(PMT)联合支架植入治疗急性髂股静脉血栓形成患者的中远期疗效。方法: 收集宁波市第二医院2015年11月至2017年11月因急性髂股静脉血栓形成行PMT联合支架植入70例患者的临床资料,观察支架植入后血流通畅改善情况,术后随访通过Villalta评分量表评估患者血栓后综合征发生情况,并行下肢超声或造影检查评估支架通畅情况。结果: 70例PMT联合髂静脉支架植入患者术后血流均明显改善,血栓Ⅲ级清除62例(88.6%),Ⅱ级清除5例(7.1%),Ⅰ级清除3例(4.3%)。吸栓期间无严重并发症发生。术后平均随访时间为(15.0±2.5)个月,64例(91.4%)患者支架通畅,9例(12.8%)患者出现不同程度的血栓后综合征。结论: PMT联合支架植入治疗急性髂股静脉血栓效果良好,中远期支架通畅率较高。
