目的探讨支架辅助大脑前动脉A1段微小宽颈动脉瘤(动脉瘤最长径≤3mm,且动脉瘤颈/瘤体宽径比≥3/4)血管内治疗的可行性及效果。方法回顾分析Neuroform支架辅助栓塞10例12个大脑前动脉A1段微小宽颈动脉瘤的临床影像、血管内治疗和随访资料。结果 10例病人均在成功植入Neuroform支架后行动脉瘤栓塞,其中致密栓塞7例,3例90%栓塞,所有患者均随访6～24月无再出血,4例术后3～6月行CTA复查,6例于术后6～12月复查血管造影,未见再生长。结论大脑前动脉A1段宽颈微小动脉瘤的血管内治疗,技术上可行,操作相对安全,有效。
Objective To investigate the feasibility and effect of stent-assisted endovascular treatment of small wide-necked aneurysms in A1 segment of anterior cerebral artery (the longest diameter of aneurysm is less than 3mm and the width of aneurysm neck / body width ratio is 3/4). Methods The clinical data, endovascular treatment and follow-up data of 10 segments of anterior cerebral arteries in 12 patients with mini-wide-necked aneurysms of the anterior cerebral artery in 10 patients with neuroform stent embolization were retrospectively analyzed. Results All 10 patients underwent aortic aneurysm embolization after the successful implantation of the Neuroform stent. There were 7 cases of dense embolism and 3 cases of 90% embolization. All patients were followed up for 6-24 months without rebleeding and 4 cases were performed from 3 to 6 months after operation CTA review, 6 cases in 6 to 12 months after angiography review, no regrowth. Conclusion The endovascular treatment of wide-necked small aneurysms in the anterior cerebral artery segment A1 is technically feasible and relatively safe and effective in operation.
