Herein, we report abdominal aortic thrombosis as a rare cause of acute spinal cord infarction. A 78-year-old man with multiple vascular risk factors developed acute paraplegia with sensory and urinary disturbances and signs of ischemia in both lower limbs. The post-mortem study done 3 days after the onset of symptoms revealed a large coagulum in the abdominal aorta, distal to the renal arteries and extending to bilateral common iliac arteries; in addition, marked atherosclerosis was present in most large blood vessels. Premature incomplete necrotic foci were seen in the ventral gray matter of the spinal cord from T6 through S5; the surrounding white matter and dorsal gray matter were spared. Considering our autopsy case, spinal cord gray matter may be more vulnerable to ischemia than the white matter.

在此，我们报告腹主动脉血栓形成是急性脊髓梗死的罕见原因。一名患有多种血管危险因素的78岁男子在下肢出现了急性截瘫，并伴有感觉和泌尿系统疾病以及局部缺血的迹象。症状发作后3天进行的验尸研究显示，腹主动脉中有大量凝结物，位于肾动脉远端，并延伸至双侧common总动脉。此外，大多数大血管中均存在明显的动脉粥样硬化。从T6到S5在脊髓的腹侧灰质中发现过早的不完全坏死灶。周围的白质和背灰质得以幸免。考虑到我们的尸检情况，脊髓灰质可能比白质更容易缺血。
