目的观察经皮血管内成形术 (PTA)和支架植入术 (SP)治疗椎动脉狭窄的临床疗效。方法对 7例经内科药物治疗无效 ,椎 -基底动脉供血不足的椎动脉狭窄患者行 PTA和 SP治疗。结果 PTA和 SP成功率为 10 0 % ,血管狭窄程度术前 (82 .86% )、术后 (0 )两者比较 ,有显著性差异 (P<0 .0 1)。术后无死亡 ,也无支架内血栓、穿孔、动脉夹层或脑梗死等并发症 ,术后 6个月复查血管造影 ,再狭窄率为 0 ,一年随访仅 1例出现一过性脑缺血 (TIA)。结论 PTA加 SP是治疗椎动脉狭窄的一种可行和危险性较小的方法 ,可预防中风和 TIA的发生
Objective To observe the clinical effect of percutaneous transluminal angioplasty (PTA) and stent implantation (SP) on vertebral artery stenosis. Methods Seven patients with vertebral artery stenosis who were not cured by internal medicine and vertebrobasilar insufficiency were treated with PTA and SP. Results The success rate of PTA and SP was 100%, the degree of vascular stenosis was 82.86% before operation and after operation (0), there was a significant difference (P <0.01). No postoperative death, no stent thrombosis, perforation, arterial dissection or cerebral infarction and other complications, 6 months after angiography review, restenosis rate of 0, only one case of one-year follow-up showed transient cerebral ischemia (TIA). Conclusion PTA plus SP is a feasible and less dangerous method for the treatment of vertebral artery stenosis and can prevent the occurrence of stroke and TIA
