Thromboembolic stroke from migration of thrombus formed in non-giant intracranial aneurysms is a recognized but rare event. We describe a case of partial thrombosis of a 7 mm anterior communicating artery aneurysm, which embolized to the right callosomarginal artery in the brief time interval between two sequential diagnostic angiograms performed as part of elective endovascular coiling, and before any instrumentation had been advanced into the intracranial circulation. To our knowledge, this is the first reported case of aneurysmal thrombus embolization observed angiographically in near real time.
非巨大颅内动脉瘤形成的血栓迁移导致的血栓栓塞性中风是一种已被认识但罕见的事件。我们描述了一例7毫米前交通动脉瘤部分血栓形成的病例，在作为选择性血管内栓塞治疗一部分进行的两次连续诊断性血管造影之间的短时间间隔内，且在任何器械进入颅内循环之前，血栓栓塞到了右侧胼周动脉。据我们所知，这是首例在血管造影中近乎实时观察到的动脉瘤血栓栓塞病例。
