目的：研究后循环串行狭窄介入治疗的安全性、可行性及疗效。方法2006年8月至2012年6月，对16例后循环串行狭窄（32处狭窄）患者行动脉成形术（支架置入或球囊扩张）。患者均为男性，年龄（63±10）岁（47~81岁）。对手术成功率、围手术期并发症、随访结果进行分析。结果1例（椎动脉开口处狭窄合并基底动脉狭窄）因支架无法到位，只对基底动脉狭窄行球囊成形术。其余患者介入治疗手术全部成功。围手术期并发症1例。对所有患者进行随访，平均（10±15）个月；1例术后5个月出现脑干动脉梗死。4例行CTA或DSA随诊（平均5.8个月），未出现再狭窄患者。结论支架置入治疗椎基底动脉串行狭窄的成功率较高，介入方法是治疗后循环串行狭窄的有效方法。

Objective To assess the safety, feasibility and efifcacy of stenting for tandem stenoses of posterior circulation cerebral artery. Methods During the period from August 2006 to June 2010, a total of 16 patients with tandem stenoses of posterior circulation were treated with stenting or balloon dilation. Sixteen men with a mean age of 63±10 (range:47~81)years were included. The technical success rate, perioperative complication and follow-up results were recorded and analyzed. Results Procedure was failed in one patient (stenosis of vertebral artery origin and basilar artery) because the stent could not cross the intracranial lesion. Complications were encountered in one patient. Clinical follow-up data were available in all patients (mean follow-up duration 10 months). Follow-up conventional angiography or CTA were available in 4 patients, and there was one stroke occurred during follow-up. Conclusions Stent-assisted angioplasty is a feasible and effective therapeutic option for tandem posterior circulation artery. Stenting for tandem stenoses of posterior circulation cerebral artery can be performed safely and effectively.
