目的:探讨同期治疗颅内外动脉狭窄合并颅内动脉瘤的策略及临床效果。方法:回顾性分析2013年4月至2018年9月于北京大学第一医院神经外科行同期血管内治疗的15例颅内外动脉狭窄合并颅内动脉瘤患者的临床资料。男性6例，女性9例，年龄（63.9±9.1）岁（范围：43~79岁）；动脉狭窄部位共15处，狭窄程度为75%~95%，其中前循环8处，后循环7处；动脉瘤共17个，最大径（5.3±1.2）mm（范围：3~7 mm），前循环动脉瘤11个，后循环动脉瘤6个。患者均行同期动脉狭窄支架成形及动脉瘤栓塞术治疗。记录患者围手术期及术后临床症状、影像学资料及并发症情况。结果:15处动脉狭窄均成功置入支架（残余狭窄<30%）；17个动脉瘤中，10个行单纯弹簧圈栓塞，7个行支架辅助弹簧圈栓塞，均完全栓塞。围手术期1例患者出现轻微脑梗死症状，其余未发生手术相关并发症。术后随访（43.8±8.2）个月（范围：24~85个月），患者术后6~12个月均复查数字减影血管造影，其中2例出现无症状性支架内再狭窄，所有动脉瘤未见复发。截至末次随访时，患者均未出现颅内出血、缺血性卒中等相关症状。结论:颅内外动脉狭窄合并颅内动脉瘤应根据血管狭窄的部位、程度及动脉瘤的大小、形态、位置、数量及两者的位置关系等因素综合分析，制定个体化的治疗策略，可给予同期血管内治疗。“,”Objective:To investigate the strategy and clinical effect of single stage treatment for intracranial or extracranial artery stenosis with intracranial aneurysm.Methods:The clinical data of 15 patients with intracranial aneurysms and extracranial or intracranial artery stenosis treated by one-stage endovascular therapy at Department of Neurosurgery of Peking University First Hospital from April 2013 to September 2018 were analyzed,respectively.There were 6 males and 9 females,aged (63.9±9.1)years (range:43 to 79 years).Fifteen arterial stenosis were found,with the stenosis rates ranged from 75% to 95%.Eight cases occurred in the anterior circulation and the other 7 cases occurred in the posterior circulation.There were 17 aneurysms,11 in the anterior circulation and 6 in the posterior.The maximal diameter was (5.3±1.2)mm (range:3 to 7 mm).All patients were treated with stenting and embolization at one stage. The operation choices,perioperative and postoperative symptoms,imaging data,and complications were recorded.Results:Stents were successfully implanted in 15 cases of arterial stenosis,reducing the stenosis rates to less than 30%.Among the 17 aneurysms,10 cases were treated by coil embolization alone,7 cases by stenting and coil embolization. Eventually all the 17 aneurysms reached complete embolization.One patient had mild symptoms of the cerebral infarction during the perioperative period,and the rest had not shown surgical complications.The follow-up time was (43.8±8.2)months (range:24 to 85 months). All the patients underwent digital subtraction angiography 6 to 12 months after operation.Among them,2 cases had asymptomatic in-stent restenosis,and no recurrence was found in aneurysms.Up to the last follow-up,no patients had showed new symptoms or signs of intracranial hemorrhage or ischemic stroke.Conclusions:For patients suffered from both stenosis and aneurysms,individualized treatment should be made based on the location and severity of the vascular stenosis and aneurysms.With careful preoperative evaluation and surgical planning,the single stage endovascular treatment for intracranial or extracranial artery stenosis combined with intracranial aneurysm is safe,feasible and effective for selected patients.
