腔内介入治疗Cockett综合征伴左下肢深静脉血栓形成

目的 探讨Cockett综合征伴左下肢深静脉血栓形成(DVT)腔内介入治疗的临床效果.方法 回顾性分析2011年1月至2015年1月收治的256例Cockett综合征伴左下肢DVT患者,采用经导管接触溶栓、球囊扩张闭塞/狭窄段或支架植入术治疗,比较治疗前后患肢周径差、远期通畅率.结果 256例Cockett综合征伴左下肢DVT患者中232例(90.6％)血栓完全溶解.24例(9.4％)部分溶解,治疗前后患肢大腿与小腿周径差分别为(7.12±2.15) cm、(4.57±2.81) cm.206例髂静脉重建患者中单纯球囊扩张46例,球囊扩张联合髂静脉支架植入160例;平均随访15个月(9～24个月),单纯球囊扩张患者失访3例,出现髂静脉闭塞26例(60.5％),血栓后综合征(PTS)21例(48.8％),球囊扩张联合支架植入患者失访11例,支架狭窄/闭塞13例(8.7％),PTS 15例(10.1％),两组闭塞/狭窄、PTS差异有统计学意义(P＜0.001).结论 导管接触溶栓、球囊扩张联合支架植入治疗Cockett综合征,具有确切的临床疗效.

Endovascular interventional therapy for Cockett syndrome associated with deep vein thrombosis of left lower extremity

Objective To evaluate the clinical effect of endovascular interventional therapy in treating Cockett syndrome associated with deep vein thrombosis (DVT) of left lower extremity.Methods The clinical data of a total of 256 patients with Cockett syndrome complicated by DVT of left lower extremity,who were admitted to authors' hospital during the period from January 2011 to January 2015,were retrospectively analyzed.The patients were treated with catheter-directed thrombolysis,balloon dilatation of the occluded or narrowed venous segment,and/or stent implantation.The circumference differences of the affected limbs before and after treatment and the long-term patency rates were compared.Results Of the 256 patients with Cockett syndrome complicated by DVT of left lower extremity,complete dissolution of thrombus was achieved in 232 (90.6％) and partial dissolution of thrombus in 24 (9.4％).The circumference difference of thigh and calf was (7.12±2.15) and (4.57±2.81) cm respectively before and after treatment.Iliac vein reconstruction was carried out in 206 patients,among them simple balloon dilatation was employed in 46 and balloon dilatation together with stent implantation was adopted in 160.The patients were followed up for 9-24 months with a mean of 15 months.In simple balloon dilatation group,3 patients lost touch with the authors during the following-up period,26 patients (60.5％) developed iliac vein occlusion and post-embolization syndrome occurred in 21 patients (48.8％).In balloon dilatation plus stent implantation group,11 patients lost touch with the authors during the following-up period,stenosis or occlusion of the stent was seen in 13 patients (8.7％),post-embolization syndrome was observed in 15 patients (10.1％).The differences in vascular stenosis or occlusion and in the occurrence of post-embolization syndrome between the two groups were statistically significant (P＜0.001).Conclusion For the treatment of Cockett syndrome complicated by DVT of left lower extremity,catheter-directed thrombolysis and balloon dilatation combined with stent implantation carry definite clinical curative effect.
