摘要目的:探讨通过改进入路一期清除腘静脉血栓提高AngioJet机械吸栓治疗全下肢型急性深静脉血栓形成的效果。方法:回顾性分析2016年3月至2018年3月31例通过改进穿刺入路对急性全下肢型深静脉血栓形成进行AngioJet机械吸栓治疗患者的临床资料。结果:31例患者中，采用对侧股静脉入路26例，另5例采用小腿深静脉入路。29例吸栓前先喷注尿激酶，7例进一步行导管溶栓治疗，26例行髂静脉球囊扩张，14例行髂静脉支架置入，平均住院时间为(7.6±1.8) d，总体血栓清除率Ⅱ级(50%～99%)16例(51.6%)、Ⅲ级(100%)15例(48.4%)。31例患者有30例获得随访，中位随访时间19.7个月，术后12个月一期通畅率为83.3%，血管闭塞的5例患者均发生了不同程度的血栓形成后综合征，发生率为16.7%(5/30)。结论:通过改进入路采用机械吸栓治疗全下肢型急性深静脉血栓形成可以一期清除腘静脉血栓，改善流入道血流，血栓形成后综合征的发生率较低。

abstractsObjective:To investigate whether the clinical efficacy of mechanical pharmacothrombectomy (PMT) in treatment of whole-lower-limb acute deep vein thrombosis (DVT) could be improved by the modified approach removing popliteal vein thrombosis.Methods:From Mar 2016 to Mar 2018, 31 patients with whole-lower-limb acute DVT were enrolled and treated with PMT by AngioJet. The clinical data was retrospectively analyzed, and the clinical efficacy was evaluated.Results:26 cases were treated by contralateral common femoral vein approach and the other 5 cases by ipsilateral calf deep vein. Urokinase was given in bolus in 29 patients before thrombectomy. After PMT, 7 cases combined with catheter-directed thrombolysis. 26 cases underwent iliac vein PTA, and 14 cases underwent iliac vein stenting. The average hospitalization days was (7.6±1.8) d. The thrombus clearance rate was grade Ⅱ (50%~99%) in 16 cases (51.6%) and grade Ⅲ (100%) in 15 cases (48.4%). 30 patients were followed up and the mean follow-up time was 19.7 months. The 12-month primary patency rate was 83.3%. All the 5 patients with occlusion had different degrees of post-thrombotic syndrome (PTS), and the incidence of PTS was 16.7% (5/30).Conclusions:The modified approach to treat the whole-lower-limb acute deep vein thrombosis with PMT is safe and effective. The popliteal vein thrombosis can be cleared in one stage. The blood inflow can be improved, and the incidence of PTS is relatively low.
