The reality in neurology departments is different where most spinal cord strokes are spontaneous with no preceding surgery or aortic aneurysm. 4. 雖然心血管危險因子和spinal infarction得相關性比大腦中風來的小，不過歐洲guideline還是建議控制。 5. Lower thoracolumbar spinal cord strokes are more common than upper cervical strokes. 6. 在神經柯理面，spontaneous spinal infarction大約占所有spinal infarction 85%，其餘的都與aortic surgery or hypotension or aortic dissection有關。 7. Prognosis: 67%最後能恢復行走能力，不過整體而言的預後相對大腦中風是好的。 8. 長期而言，小於60歲的病人最後幾乎都能回到職場。 9. Up t...
