Reekross球囊导管在治疗长段髂股动脉闭塞病变中的应用

Evaluation of Reekrossballoon catheter to treat long-segment occlusion of iliofemoral artery

目的 评估利用Reekross球囊导管开通长段髂股动脉闭塞性病变的安全性和有效性.方法 选取北京协和医院2011年1月至2013年5月应用Reekross球囊导管进行血管腔内治疗的68例髂股动脉长段慢性闭塞病变（CTO）患者（75条肢体）,所有患者均为泛太平洋协作组共识（TASC）ⅡC、D级.其中男53例,女15例;年龄47 ～ 89（69±12）岁.肢体按Rutherford下肢缺血分期为3期41条,4期13条,5期19条,6期2条.总结分析技术成功率、患肢术后临床症状、踝肱指数（ABI）变化、并发症发生率及通畅率.结果 Reekross球囊导管开通病变技术成功率为90.7％（68/75）,ABI从术前的（0.41±0.12）提升至术后3d的（0.77±0.20）,差异有统计学意义（t=-7.263,P＜0.01）.56例患者（61条肢体）随访12～40个月,平均（26.3±7.1）个月.术后3、6、12及24个月累计一期通畅率分别为（98.4±1.6）％、（86.7±4.4）％、（80.0±5.2）％及（69.4±6.3）％.结论 Reekross球囊导管在治疗髂股动脉CTO病变中具有良好的应用价值,方法安全有效.

Objective The purpose of this study was to examine the safety and efficacy of the Reekross balloon catheter for recanalization of long CTO of iliofemoral arteries.Methods A retrospective analysis of patients with long CTO of iliofemoral arteries who underwent angioplasty with Reekross balloon catheter between January 2011 and May 2013 was performed.All lesions were TASC Ⅱ C and D.Sixty-eight patients（75 limbs） were enrolled with mean age of （69 ± 12）years,53 male and 15 female.The limbs of Rutherford Ⅲ,Ⅳ,Ⅴ and Ⅵ[were 41,13,19 and 2.Technical successrate,ankle brachial index （ABI）,complication rate,and cumulative primary patency rate were evaluated.Results Technical success ratewas 90.7％.ABI increased from pre-procedure （0.41 ± 0.12） to 3-day post-procedure （0.77 ± 0.20） （t =-7.263,P ＜0.01）.Follow-up was achieved in 56 cases（61 limbs） from 12 to 40 months,with a mean of （26.3 ± 7.1）months.Primary patency rates at 3 months,6 months,12 months and 24 months were （98.4 ± 1.6） ％,（86.7 ± 4.4） ％,（80.0 ± 5.2） ％ and （69.4 ± 6.3） ％.Conclusion The Reekross balloon catheter is safe and effective for successful recanalization of CTO of iliofemoral artery.
