Subintimal angioplasty in treatment of femoropopliteal TASC Ⅱ type C and type D lesions

目的观察内膜下血管成形术治疗股胭动脉 TASCⅡC、D 型病变的近期疗效。方法回顾性分析采用内膜下血管成形术治疗的48例以股腘动脉病变为主的动脉硬化闭塞症患者的临床资料。结果 48例患者中,技术成功38例,临床症状改善40例。患者术后平均随访12个月(1～21个月),临床症状消失和缓解的患者中有6例术后2～6个月症状复发,行第2次介入治疗,其余患者症状均无加重或复发。结论内膜下成形术治疗粥样硬化导致的股腘动脉段 TASCⅡC、D 型病变完全可行,近期疗效确切,其长期疗效还需进一步随访观察。

Objective To evaluate short-term results in subintimal angioplasty （SA） treatment of femoropopliteal TASC Ⅱ type C and type D lesions. Methods Forty-eight patients with femoropepliteal artery occlusive disease and treated by SA were retrospectively analyzed. Results The operation was successful in 38 cases, the symptoms of patient were improved in 40 cases. The mean follow-up time after procedure was 12 months （from 1 to 21 months）. During the follow-up, 6 cases among the clinical success group appeared recurrence after therapy 2 to 6 months, and underwent a further PTA. The others have no recurrence. Conclusion SA is a feasible technique for femoropopliteal artery occlusive disease. Short-term effect is remarkable, but long-term results are needed to be further evaluation.
