Wide-necked cerebral aneurysms have been particularly difficult to treat using coil embolization. The introduction of the first intracranial flexible stent (Neuroform stent; Boston Scientific/Target, Fremont, CA) has provided a great advantage to this dilemma by forming a bridge across the aneurysm neck and allowing the packing of coils. Despite this advancement, some parent vessel bifurcation aneurysms can still remain elusive to single stent and coiling technique.
A 55-year-old woman presented for a routine follow-up angiogram. Her past history was significant for a subarachnoid hemorrhage and clipping of an anterior communicating aneurysm with full recovery. An incidental new right middle cerebral artery aneurysm was found on the angiogram. We report here a case of an unruptured asymptomatic wide-neck middle cerebral artery bifurcation aneurysm that was treated with a novel endovascular repair.
The aneurysm was successfully treated using a double stent "Y" configuration and coil embolization technique using the Neuroform stent. Technical aspects are discussed. Perioperative management issues and potential pitfalls are also considered.
Double stenting in "Y" configuration and coiling is feasible. This technique should increase the ability to endovascularly treat wide-necked aneurysms.
宽颈脑动脉瘤采用弹簧圈栓塞治疗一直颇具难度。首款颅内可弯曲支架(Neuroform支架;波士顿科学公司/Target,加利福尼亚州弗里蒙特)的问世为解决这一难题带来了巨大优势,它可在动脉瘤颈部搭建桥梁,便于填入弹簧圈。尽管有了这一进展,但对于一些母血管分叉处的动脉瘤,单一支架和弹簧圈技术仍可能难以奏效。
一名55岁女性前来进行常规随访血管造影。她既往有蛛网膜下腔出血病史,曾接受前交通动脉瘤夹闭术,术后完全康复。此次血管造影偶然发现右侧大脑中动脉有一新发动脉瘤。我们在此报告一例未破裂无症状的宽颈大脑中动脉分叉处动脉瘤,采用新型血管内修复术进行治疗。
使用Neuroform支架,采用双支架“Y”形构型及弹簧圈栓塞技术成功治疗该动脉瘤。文中讨论了技术要点。还考虑了围手术期管理问题及潜在陷阱。
“Y”形构型双支架及弹簧圈栓塞术是可行的。该技术应能提高血管内治疗宽颈动脉瘤的能力。
