Results: The male patients appeared more than females in spinal cord AVMs, but the occult intramedullary AVMs had the same morbidity The patients with intramedullary AVMs and perimdeullary AVF were younger, in contrast, patients with dural AVF were usually older than 40 years of age. The intra - medullary AVMs were most common located in the cervical and thracic - lumbar spinal cord, the perimedullary AVF and dural AVF were most seen in the low thracic of lumbar region. The most common initial symptom associated with intramedullary lesions was accute onset where as the progressive aggravation was the most common presenting symptom in cases of dural AVF. The prognosis of the patients with intramedullary lesions had hemorrhage was worse than who without hemorrhage.

结果：脊髓AVM s中，隐匿型AVMs无明显的性别差异，余各类型男性均多于女性；髓内AVMs、髓周AVF以青少年多见，硬膜型AVF发生于中老年；髓内AVMs多见于颈髓及胸腰段脊髓，髓周AVF及硬膜型AVF多见于胸腰段；髓内AVMs以急性起病多见，髓周AVF表现为进行性加重，少数可急性发作，硬膜型AVF以慢性起病多见；髓内出血者预后较无出血者差。
