塞栓術と放射線治療が奏効した特発性CCFの2例

After super-selective embolization of the external carotid arterial branch, some improvement in the symptoms of two patients (63-year-old female, 68-year-old female) were observed, but some symptoms continued after the embolization. One month after the embolization, external irradiation (10MeV X ray, 2Gy/day, 5fr/W, total 30Gy) was administered to the region of the fistula. An angiogram after completion of the irradiation showed complete disappearance of CCF, and almost complete improvement of symptoms was observed. For three years following the completion of irradiation, neither recurrence of sympoms nor side effects were noted.
