摘要
目的探讨内膜下再通技术(SIR)治疗股腘动脉粥样硬化闭塞病变的技术要点和疗效。方法使用内膜下再通技术治疗患者股腘动脉完全闭塞病变42例。使用超滑导丝穿通闭塞段动脉内膜下腔,通过闭塞段后重新进入流出道真腔。建立闭塞段动脉内膜下通道后,用球囊腔内成形及支架置入以保证管腔通畅。结果 39例患者内膜下再通治疗获得成功,临床症状显著改善。技术成功率92.9%(39/42)。3例技术失败,原因是导丝不能重入流出道真腔。结论内膜下再通技术治疗长段慢性股腘动脉粥样硬化闭塞病变可行性强,疗效显著、安全性好、技术相对简便。
Objective To discuss the technical points and clinical efficacy of subintimal recanalization technique in treating chronic long-segment total occlusion of femoropoliteal artery.Methods Forty-two patients with chronic long-segment total occlusion of femoropoliteal artery underwent subintimal recanalization treatment.The basic procedure of subintimal recanalization was as follows.First,a subintimal path in the wall of the occluded artery was created by inserting a super-slip guide wire and the guide wire was then pushed into the true lumen of the outflow tract,which was followed by balloon angioplasty and stent placement to insure the patency of the re-canalized path.The technical points were discussed and the clinical results were evaluated.Results The subintimal recanalization of occluded arterial segment was successfully achieved in 39 patients.The clinical symptoms were promptly and remarkably relieved after the procedure.The technical success rate was 92.9%（39/42）.Technical failure occurred in three patients because the guide wire could not be managed into the true lumen of the outflow tract.Conclusion The subintimal recanalization is an effective and safe technique for the treatment of chronic long-segment total occlusion of femoropoliteal artery.
