支架置入术治疗颅内外动脉狭窄引起跌倒发作的疗效观察(附2例报告)

Therapeutic effects observation of endovascular stenting on the patients with drop attacks caused by carotid artery or vertebra-basilar artery stenosis(report of 2 cases)

目的观察应用血管内支架成形术治疗颅内外动脉狭窄引起的跌倒发作的疗效。方法对2例颅内外动脉狭窄引起的跌倒发作患者(例1为基底动脉的中部、起始部,左椎动脉起始部及左锁骨下动脉重度狭窄;例2为双侧颈内动脉起始部重度狭窄)予以血管内支架成形术治疗,共释放6枚支架,例2应用保护伞。术后随访9个月～2年。结果术后2例患者临床症状消失。例1随访9个月,术后6个月起因不规律服药,3个月后死于脑干梗死;例2术后1年复查DSA,无发生再狭窄,随访2年无临床症状复发。结论血管内支架成形术是治疗颅内外动脉狭窄引起的跌倒发作安全、有效的方法。

Objective To observe the therapeutic effects of endovascular stenting on the patients with drop attacks caused by carotid artery or vertebra-basilar artery stenosis. Methods Two drop attacks patients, who were diagnosed with symptomatic carotid artery or vertebra-basilar artery stenosis by DSA, were performed endovascular stenting. Case one had four serious artery stenoses at basilar artery, left vertebra artery and subclavian artery. Case two had double internal carotid artery. Six stents were placed, and filter protection devices were used in case two. After operating, the flowing up was performed for nine months or two years. Results The clinical symptoms of two patients were disappeared after operation. Case one performed flowing up for 9 months after operation, but he died by infarction of brain stem for his irregular taking medicine for 3 months since 6 months after operation. During flowing up for 2 years, case two was no relapse and no restenosis by DSA peoformed at 1 year after operating. Conclusions Endovascular stenting is a safe and efficient method for treating the patients with drop attacks caused by carotid artery or vertebra-basilar artery stenosis.
