A 60-year-old man suffered from paraplegia after the operation for thoracic aortic aneurysm and died 10 months after the operation. Detailed examination on the distribution of spinal cord lesions and of the locations of anterior radicular arteries revealed that the spinal cord ischemia occurred at the mid-thoracic segments between T-6 and T-10; the artery of Adamkiewicz entered at T-12; another radicular artery entered at T-4. We concluded that the spinal cord ischemia was caused by the interruption of the radicular artery at T-4 and that the segments nourished by the blood flow of the artery of Adamkiewicz were intact. We suggest that in some patients important radicular arteries other than the artery of Adamkiewicz are essential to preserve blood flow to the upper or middle thoracic spinal segments.
一名60岁男性在胸主动脉瘤手术后出现截瘫，并于术后10个月死亡。对脊髓损伤分布及前根动脉位置的详细检查显示，脊髓缺血发生在胸段中部T-6至T-10之间；Adamkiewicz动脉在T-12进入；另一根根动脉在T-4进入。我们得出结论，脊髓缺血是由T-4处根动脉中断引起的，且由Adamkiewicz动脉血流滋养的节段完好无损。我们建议，在一些患者中，除Adamkiewicz动脉外，其他重要的根动脉对于维持胸段脊髓上、中段的血流至关重要。
