迂曲径路下支架成形术治疗症状性大脑中动脉狭窄

目的 探讨在严重迂曲的血管径路下,大脑中动脉重度狭窄的血管内支架成形技术.方法 对18例症状性大脑中动脉狭窄(狭窄率>50%)患者进行血管内支架成形术,颈内动脉虹吸段严重迂曲,导丝/支架难以通过,其中5例在首先采用单导丝技术,无法使支架释放系统顺利到达狭窄病变后,改用双导丝技术来完成血管内支架成形术.结果 在严重迂曲血管径路下,标准的单导丝技术无法成功时,采用双导丝技术能够成功完成大脑中动脉支架成形术.结论 对严重迂曲血管径路的颅内动脉狭窄病变采用双导丝技术町以明显提高手术成功率.

Techniques in angioplasty with stent for stenosis of middle cerebral artery with extremely tortuous access

Objective To explore the techniques with angioplasty and stenting for symptomatic stenosis of middle cerebral artery (MCA) with extremely tortuous access. Method Angioplasty and stenting was performed in 18 patients with symptomatic stenosis of MCA( >50% ). The guidingwire and stenting -system could not be dilivered to the stenotic lesions via standard technique of single wire in 5 patients for extremely tortuous cartoid siphon. So we chose the technique of double wires. Results Angioplasty and stenting was performed successfully in patients by double - wire technique when the standard single - wire techniques failed. Conclusions Double - wire technique used in intracranial stenosis with extremely tortuous access could obviously raise the rate of successful angioplasty and stenting.
