血管内治療で改善した頸動脈海綿静脈洞瘻の2例

Endovascular embolization was effective in two cases of carotid cavernous sinus fistula

要約　目的：血管内治療が奏効した頸動脈海綿静脈洞瘻の2症例の報告。症例：それぞれ69歳男性と85歳女性で，片眼の結膜浮腫と著明な血管蛇行があり，眼球運動障害と眼圧上昇があった。1例には1か月前，他の1例には4日前に眼症状が生じた。両症例とも脳血管造影で頸動脈海綿静脈洞瘻と診断され，カテーテルによる血管内治療で眼症状が軽快した。結論：頸動脈海綿静脈洞瘻にはカテーテルによる血管内治療が奏効する。その診断では，眼症状から脳血管障害を疑うことが重要である。

Abstract.　Purpose：To report two cases of carotid cavernous sinus fistula（CCF）that improved after endovascular embolization. Cases：The present series comprised 69-year-old male and an 85-year-old female. Findings：Both cases showed unilateral conjunctival edema and tortuous vessels,restricted ocular movement,and elevated intraocular pressure. The symptoms had been present for one month in one case and for 4 days in the other. Both cases were diagnosed with CCF by cerebral angiography. Endovascular embolization resulted in improvement of ocular symptoms. Conclusion：These cases illustrate that endovascular embolization may be effective for CCF. Cerebral vascular lesion will have to be considered in the presence of ocular manifestations.
