BACKGROUND AND PURPOSE A complex middle cerebral artery (MCA) aneurysm failed surgical clipping. The aneurysm morphology was characterized by a broad neck with incorporated diminutive branch vasculature and mural calcification. To preserve flow within incorporated branch vessels, coil embolization with intraaneurysmal Neuroform stent implantation was achieved with a novel technique. METHODS AND RESULTS A 52-year-old female presented with an unruptured complex configuration right MCA bifurcation aneurysm. Endovascular coil embolization with intraaneurysmal stent deployment and compartmental dual microcatheter placement was performed a month after failed surgical clipping. Successful occlusion of the aneurysm with coil packing within and external to the stent was achieved with preservation of flow to the branch vessels. CONCLUSIONS Neuroform stent implantation within the aneurysm lumen and subsequent dual catheter coil embolization of the compartments external and internal to the stent is useful for successful occlusion of complex configuration cerebral aneurysms with incorporated branch vasculature.
复杂大脑中动脉（MCA）动脉瘤经手术夹闭失败。该动脉瘤形态学特征为宽颈，合并细小分支血管和壁钙化。为了保留合并分支血管内的血流，采用一种新的技术，进行了瘤内 Neuroform 支架植入弹簧圈栓塞。
一位 52 岁女性因未破裂的复杂右侧 MCA 分叉部动脉瘤就诊。在手术夹闭失败一个月后，进行了血管内弹簧圈栓塞和瘤内支架置入术，同时采用了腔内双微导管放置术。通过支架内和支架外的线圈填塞，成功地闭塞了动脉瘤，同时保留了分支血管的血流。
在动脉瘤管腔内植入 Neuroform 支架，然后通过腔内双微导管对支架内外的腔室进行弹簧圈栓塞，对于合并分支血管的复杂形态脑动脉瘤的成功闭塞是有用的。
