摘　　要：本文讨论了３１例Ｃｈｉａｒｉ畸形并脊髓空洞症的后颅窝减压和（或）空洞－蛛网膜下腔分流手术，并评价其术后临床表现和部分ＭＲＩ影像的改变。本组资料表明，根据临床征象选择适当的后颅窝减压方式，依ＭＲＩ矢状像上空洞／脊髓比值大于３０％做为分流指征，症状和体征可有不同程度的改善。９例术后ＭＲＩ复查表明脊髓空洞平均缩小１７％。脊髓空洞的大小与脊髓损害程度无明确关系。Abstract Thirty -one patients with syringomyeliaChiari complex underwent different posterior fossa decompression and (or) syringosubarachnoid shunting were studies. The changes of the syrinx were checked by MRI and clinical manifestation were evaluated. Patients were improved in varying degrees in different kind of decompression. If the syringo-cord ratio over 30% on the sagittal section of MRI syringosubarachnoid shun were performed after decompression. The syrinx size in 9 patients was reduced by 17% averagely.There is no significant relationship between the size of syrinx on MRI and the degree attributed to spinal cord damage.
