Irradiation of spontaneous carotid-cavernous fistulas.
Two patients with spontaneous carotid-cavernous fistulas were successfully treated with cobalt 60 irradiation to the sellar region. Angiographically, one patient showed combined-type shunts comprising a dural internal carotid-cavernous fistula and a direct internal carotid-cavernous fistula; the other patient had a mixed dural external and internal carotid-cavernous fistula. The respective total radiation dose was 3,200 rads and 3,024 rads. The patients responded satisfactorily to the treatment, with disappearance of the fistulas on angiograms and patency of the internal and external carotid arteries.
