頸動脈海綿静脈洞瘻の自然治癒例

Spontaneously Cured Carotid-cavernous Fistula Verified by Angiography-Report of a Case

Ⅰ．はじめに

　頸動脈海綿静脈洞瘻（c-c fistula）の自然治癒率は，従来，臨床症状や剖検所見から，ほぼ10％^1,6,8）と推定されているが，脳血管撮影で確認された報告は，意外な程少数であり，筆者らの渉猟した限りでは，10例にも満たない．

　最近，右大脳動脈瘤を伴ったc-c fistulaの自然治癒例を経験し，前後4回の脳血管連続拡大撮影で追跡検討したので，主に脳血管撮影で確認されたc-c fistulaの自然治癒例について，若干の文献的考察を行い報告する．

A case of spontaneously cured carotid-cavernous fistula has been reported in details with a review of literatures. Seven cases verified by angiography have been described so far in the literature. Spontaneous cure has been revealed within 6 months after the initial examination in 5 out of 7 cases by follow up angiography, and has occured in five women of middle age.

The presented case was a 45 year-old female who has suffurred from the exophthalmos associated with disturbed eye movements of two months duration.
