Context: Spinal cord infarction is a rare condition that develops as a result of insufficient vascular perfusion, sometimes related to procedures involving the aorta and vertebral arteries.

Findings: We present the case of a 66-year-old woman who developed weakness on all four extremities and thermalgesic sensory deficit following an elective endovascular embolization of an incidentally diagnosed aneurysm in the posterior circulation. The procedure involved the cathetherization of both vertebral arteries, but was unremarkable and the flow into the anterior spinal artery was preserved. Radiological findings highly suggested a spinal cord infarction. She was started on corticosteroids and showed a significant neurological improvement.

Clinical relevance: The present case illustrates that spinal cord infarction is a typical – but uncommon – complication that has to be suspected after vertebral artery endovascular procedures. It can result from hypoperfusion of smaller branches that irrigate the cervical spinal cord, and patients can make remarkable recoveries despite severe initial deficits.

背景：脊髓梗死是一种罕见的疾病，由血管灌注不足引起，有时与涉及主动脉和椎动脉的手术有关。

结果：我们介绍了一名 66 岁女性的病例，她在对偶然诊断的后循环动脉瘤进行选择性血管内栓塞后出现四肢无力和热敏性感觉障碍。该过程涉及两个椎动脉的导管插入术，但并不显着，并且保留了流入脊髓前动脉的血流。放射学检查结果高度提示脊髓梗死。她开始使用皮质类固醇，并表现出显着的神经功能改善。

临床相关性：本病例说明脊髓梗死是一种典型但不常见的并发症，在椎动脉血管内手术后必须怀疑。它可能是由于冲洗颈脊髓的较小分支灌注不足所致，尽管最初有严重的缺陷，患者仍可取得显着的恢复。
