Posterior cerebral artery aneurysms are treatment challenge for the neurosurgeon. Parent artery occlusion, trapping and bypass have been the classic treatment options for aneurysms in this location. With the introduction of newer embolic agents such as Onyx®, endovascular intervention is now a viable therapy for these aneurysms.
We report the case of a 60-year-old man who presented with a symptomatic, though unruptured, fusiform left posterior cerebral artery aneurysm. Given the distal location of this dominant sided aneurysm, post-operative visual deficits and aphasia were a concern if parent vessel occlusion were to be performed. Therefore, an endovascular reconstruction using Onyx HD-500 and two closed-cell stents was performed.
This report illustrates the ability of a high-density liquid embolic agent to provide immediate reconstruction of a fusiform aneurysm in a distal location.
大脑后动脉动脉瘤对神经外科医生来说是一个治疗挑战。对于该部位的动脉瘤，其经典治疗方案包括母动脉闭塞、夹闭和旁路。随着新型栓塞剂如 Onyx®的引入，血管内介入治疗现在成为这些动脉瘤的可行治疗方法。
我们报告了一例 60 岁男性，患有症状性但未破裂的梭形左侧大脑后动脉动脉瘤。由于该优势侧动脉瘤位于远端，因此如果进行母血管闭塞，术后视力缺损和失语是一个令人担忧的问题。因此，我们采用 Onyx HD-500 和两个闭孔支架进行血管内重建。
本报告说明了一种高密度液体栓塞剂在提供远端梭形动脉瘤即刻重建方面的能力。
