血管内支架成形术治疗症状性弓上颅外动脉狭窄

Angioplasty and Stenting for Symptomatic Supra-Arch Extracranial Artery Stenosis

目的 总结血管内支架成形术治疗症状性弓上颅外动脉狭窄的短期疗效和安全性。方法2003年2月～2005年8月，应用血管内支架成形术治疗症状性弓上颅外动脉狭窄46例。结果治疗狭窄动脉共48根，技术上全部成功，狭窄程度由原来的（65．2±10．9）％下降至（9．6±4、6）％，无一例死亡，围手术期发生手术相关并发症3例（6.5％），随访（8．0±6．1）个月，颈部动脉超声检查无再狭窄发生。结论血管内支架成形术是治疗症状性弓上颅外动脉狭窄安全有效的方法。

Objective To summarize the short-term result and safety of treating symptomatic supra-arch extracranial artery stenosis with angioplasty, and stenting. Methods Forty-six patients with symptomati tracranial artery stenosis were treated between February 2003 and August 2005. Results Forty-e treated. Technically successful procedure was achieved （ 65.2±10.9 ） % to （9.6±4.6 ） %. No death occured c supra-arch exight lesions were in all the patients. The diameter stenosis was decreased from Three patients（6.5% ） experienced procedure-related complications. The patients were followed up for （8.0±6.1 ） months. No restenosis was found by the cervical arterial ultrasonic examination Conclusion Angioplasty and stenting is safe and valid treatment for symptomatic supra-arch extracranial artery stenosis.
