Cerebral artery aneurysms are present in up to 10% of ischemic stroke patients, often within or adjacent to the occluded vessel. In some cases, the approach to intervention may need to be modified based on the size and location of the aneurysm. We describe a 99-year-old female with a known history of cerebral aneurysm who underwent successfully mechanical thrombectomy of a right middle cerebral artery thrombus; an 8-mm aneurysm involving the right M1 bifurcation was identified only on post-procedural digital subtraction angiography. In addition, we discuss strategies to reduce the risk of iatrogenic aneurysm rupture in the setting of endovascular thrombectomy.
高达10%的缺血性中风患者存在脑动脉瘤，通常位于闭塞血管内或其附近。在某些情况下，可能需要根据动脉瘤的大小和位置调整干预方法。我们描述了一名99岁女性，她有脑动脉瘤病史，成功接受了右大脑中动脉血栓的机械取栓术；仅在术后数字减影血管造影中发现一个8毫米的动脉瘤，累及右M1分叉处。此外，我们还讨论了在血管内取栓术中降低医源性动脉瘤破裂风险的策略。
