In the present case the thrombosis of a spontaneous CCF by a combination of hypotension and radiation therapy was attemped.<BR>The patient, a 50-year-old female, had experienced a tinnitine bruit on the left side for about six months. For one month there was also double vision and impairment of the left eye. When she was hospitalized, the bruit was inaudible but the left eye protruded with some hyperemia and edema. There was double vision in every direction except for straight ahead. The CCF was revealed only in the left internal carotid angiogram. The arteriovenous shunt showed relative high flow and pressure. When the systemic blood pressure was decreased by the hypotensive drugs, the bruit became weak and transient. The radiation therapy was commenced, and after 2000 rads, the CCF had decreased in size. The radiation therapy was finished at a total dosage of 3600 rads. On the patient's discharge from the hospital, some visual impairment remained, so hypotensive drugs were continued. The symptoms gradually improved. It was confirmed by the angiography one year that the CCF had completely disappeared, and there was no recurrence in the ensuing 12 months.<BR>We wish to emphasize that the decrease of systemic blood pressure brings a decrease of pressure and flow of the shunt with consequent thrombosis. This is a new method for the treatment of small vascular anomalies.
