| 中文摘要:目的探讨血管腔内成形术对于TASC B、Ｃ型下肢动脉硬化性闭塞症的临床疗效。方法共40例患者（47条肢体），采用经皮穿刺股动脉,造影明确病变动脉部位及病变长度后,行球囊导管行扩张成形和血管内支架置入。术后采用彩色多普勒超声或CTA检查随访。结果47条肢体获得成功，技术成功率为96%，共置入自膨式支架31枚,16条仅行PTA。踝肱指数由术前的0.36±0.14增至术后7天的0.82±0.15；随访1~48个月,术后4例发生支架再闭塞，1例再狭窄，其余患者随访期内下肢血流通畅。讨论血管腔内成形术以其微创及安全性，可作为长段（包括膝下）动脉硬化性闭塞症治疗的可选手段。 |

| Abstract:ObjectiveTo evaluate the clinical effects of endovascular angioplasty and stenting for the treatment of TASC B, C arteriosclerotic occlusion(ASO) of lower extremity.MethodsAfter the identification of the occlusion by angiography via femoral artery access by Seldinger method, the occluded arteries (mean length 7.5cm; range 1~20 cm) in 40 patients(47limbs) were treated by percutaneous transluminal angioplasty and stent placement. ResultsThe primary recanalization was successful in 45 of 47 limbs. The technical successful rate was 96%. Thirty one self-expanding stents were deployed. PTA without stent placememt was performed in 16 limbs(of them, 11 were blow knee).The ankle brachial pressure index (ABI) increased from (0.36±0.14) preoperatively to (0.82±0.15) on the 7th postoperative day. All patients were follow-uped for 1 to 48 months. Stents were occluded in 4 patients. Restenosis was observed in 1 limbs. All of the rest remained patent in the follow-up period.ConclusionEndovascular angioplasty and stenting can be an effective method for the treatment of long segmental (including below-knee) arteriosclerotic occlusion of lower extremities. |
