title: [Gamma knife radiosurgery for spontaneous carotid-cavernous sinus fistula (CCF)].
abstract: Gamma knife radiosurgery was carried out for spontaneous CCF (carotid-cavernous sinus fistula) in 8 patients (1 male and 7 females), and its results were reported. The ages ranged from 48 to 74 years with a mean of 60.6 years. As initial treatment before radiosurgery, embolization was carried out except in one patient, and radiotherapy was used in two patients. Six patients were in the category of Barrow's type D, and two patients were in the category of Barrow's type B. As it contained the fistula, the lateral wall of the cavernous sinus was irradiated with 8-14.5 Gy (mean 10.8 Gy). As a result, complete obliteration of CCF was confirmed by DSA in seven of the eight patients between 6 and 18 months after radiosurgery. There were no side effects observed during a follow-up period of 8 to 116 months. Although the main treatment for spontaneous CCF is intravascular surgery at present, gamma knife radiosurgery is a useful adjuvant treatment for the residual CCF after embolization.
