Abstract  

Objective: To compare the efficacy of mechanical thrombectomy with transcatheter thrombolysis in the treatment of acute iliac femoral venous thrombosis. Methods: The clinical data of 170 patients with acute iliac venous thrombosis treated in Ningbo No.2 Hospital from September 2015 to September 2017 were retrospectively reviewed. Among them, 94 cases were treated with AngioJet mechanical thrombolysis or additional thrombolysis for residual thrombus (PMT group) and 76 cases were treated with catheter-directed thrombolysis(CDT group). After thrombolytic treatment if there was stenosis of iliac vein, the transluminal angioplasty was also performed. The clearance of thrombus and safety were evaluated and compared between two groups. Results: In PMT group there were 86 cases (91.5%) with grade Ⅲ, 5 cases (5.3%) with grade Ⅱ, 3 cases (3.2%) with grade Ⅰ clearance of thrombus; while in CDT group, there were 63 cases (82.9%) with grade Ⅲ, 7 cases (9.2%) with grade Ⅱ and 6 cases (7.9%) with grade Ⅰ clearance of thrombus (P>0.05). The differences of diameter of two lower extremities 15 cm above knee after treatment in PMT and CDT groups were (2.3±0.9) cm and (2.5±1.1) cm, respectively (P>0.05). The time of thrombolysis in group PMT was significantly shorter than that in group CDT[(2.6±1.2) d vs. (5.3±1.5) d, P < 0.05]. The dosage of urokinase in PMT group was significantly lower than that in CDT group[(15.0±5.0)×105 U vs. (26.5±7.5)×105 U, P < 0.05]. Hemoglobin decrease was observed in both groups, which was more significant in PMT group (P < 0.01). During the following period, there was no significant difference in the incidence of recurrence and post-thrombosis syndrome in two groups (all P>0.05). Conclusion: Both PMT and CDT have good thrombus clearance effect in the treatment of acute iliac femoral venous thrombosis, however, PMT has the advantages of short thrombolytic time and less urokinase.

经皮机械血栓清除治疗急性髂股静脉血栓形成患者疗效观察

目的: 探讨经皮机械血栓清除(PMT)或联合导管直接溶栓(CDT)与单纯CDT治疗急性髂股静脉血栓形成的临床效果。方法: 回顾性分析宁波市第二医院血管外科2015年9月至2017年9月采用PMT和CDT治疗急性髂股静脉血栓形成患者的临床资料。PMT组94例采用AngioJet机械血栓清除系统,若血栓残留则联合CDT治疗;CDT组76例单纯行CDT治疗;两组血栓清除后若存在髂静脉狭窄则联合腔内血管成形术。评估并比较两组的血栓清除程度及安全性。结果: PMT组血栓清除程度达Ⅲ级86例(91.5%),Ⅱ级5例(5.3%),Ⅰ级3例(3.2%);CDT组血栓清除程度达Ⅲ级63例(82.9%),Ⅱ级7例(9.2%),Ⅰ级6例(7.9%),两组差异无统计学意义(P>0.05)。两组患者经治疗后下肢肿胀症状均得到有效缓解,双下肢膝上15 cm周径差分别为(2.3±0.9)cm和(2.5±1.1)cm(P>0.05)。PMT组溶栓时间较CDT组缩短[(2.6±1.2)d与(5.3±1.5)d,P < 0.05],尿激酶用量减少[(15.0±5.0)×105U与(26.5±7.5)×105U,P < 0.05]。PMT组术后血红蛋白下降(10.2±4.6)g/L,下降幅度较CDT组增加(P < 0.01)。随访期间,两组患者血栓复发及血栓形成后综合征的发生率差异均无统计学意义(均P>0.05)。结论: PMT与CDT治疗急性髂股静脉血栓形成均有很好的血栓清除效果,且PMT溶栓时间短、尿激酶用量少,安全可靠。
