目的:讨论西宁地区(平均海拔2 260m)对症状性椎动脉起始部狭窄血管内支架成形术方法、效果。方法:11例椎动脉起始部狭窄的病例,术前行头颅脑动脉CT造影(CTA)及头颅磁共振成像(MRI),脑动脉数字减影血管造影(DSA)检查,在神经安定镇痛麻醉下行椎动脉起始处支架12枚。结果:本组11例手术均成功,置入球囊扩张支架11枚,自膨支架1枚;术后有11例患者临床症状有好转或消失,术中2例有一过性头晕,1例小脑梗死。结论:对内科药物保守治疗无效的症状性椎动脉起始部狭窄患者,选择性血管内支架成形术介入治疗,近期疗效明显。
OBJECTIVE: To discuss the method and effect of X-ray in the area of stenosis (mean height 2 260 m) for symptomatic vertebral artery stenosis. Methods: Eleven cases of stenosis at the beginning of vertebral artery were examined with CTA, MRI and DSA before operation. The neuroendocrine analgesia Anesthesia 12 vertebral artery stent at the beginning. Results: The operation of 11 cases in this group was successful. There were 11 balloon-stenting and 1 self-inflating stent. The clinical symptoms of 11 patients were improved or disappeared after surgery, 2 cases had transient dizziness, 1 case of cerebellum Infarct. CONCLUSIONS: In the short term, the interventional therapy of selective endovascular stenting is effective in the treatment of patients with symptomatic vertebral artery stenosis who are ineffective in the conservative treatment of internal medicine.
