8、 K1,Lu X,Li W,Huang Y,Huang X,Lu M,Jiang M.A total of 227 stents were placed in 205 patients(224 limbs;median age,50.53 years).The rate of technical success was 100%.Three limbs were treated with two stents because of proximal migration of the incipient stent.Follow-up periods ranged from 1-117 mont

9、hs(mean 50 months 36).The primary and assisted-primary cumulative patency rates at a mean of 4 years were 98.7%and 100%.The cumulative edema relief rate was 89.1%(156 of 175),and the healing rate for active ulcers was 82.3%(51 of 62).The pain level(using a visual analogue scale from 0-10)declined fr

11、onsecutive series of 48 patients.Liu Z1,Gao N2,Shen L3,Yang J2,Zhu Y2,Li Z4,Si Y5.The prevalence of IVCS within our cohort was 14.8%(48/324).The technical success rate of the endovascular treatment was 95.8%.There was no death,pulmonary embolism,or contrast-induced nephropathy among the patients.The

12、 1-year primary patency rate was 93.0%.IVCS is more common than previously thought among patients with unilateral left lower limb chronic venous disease.Endovascular therapy,a minimally invasive approach to treating venous lesions,is a feasible and effective treatment for left-sided IVCS and has a high technical success rate and an acceptable complication profile.结论结论髂静脉狭窄支架治疗：髂静脉狭窄支架治疗：有效，安全，微创，技术成功率高，并发有效，安全，微创，技术成功率高，并发症低，近期、中期通畅率高症低，近期、中期通畅率高需解决的问题需解决的问题 腹股沟处静脉闭塞腹股沟处静脉闭塞 支架治疗后抗凝、抗血小板治疗策略支架治疗后抗凝、抗血小板治疗策略 狭窄处理程度狭窄处理程度 IVUS应用应用 髂静脉阻塞的血流动力学髂静脉阻塞的血流动力学 评估等等评估等等杂交手术杂交手术谢 谢
