Obstructive Hydrocephalus Produced by Venous Ectasia of Dural AV Fistula

Dural arteriovenous fistula (Dural AVF) is an anomalous shunt between dural arterial and venous channels. About 10–15% ofall intracranial vascular malformation are dural fistulas which represent anomalous shunts among arterial branches and duralvenous sinuses, meningeal, or cortical veins.We are presenting a rare case of dural AVF treated by transarterial embolizationand complicated by hydrocephalus.

Treatment of traumatic trigeminal-cavernous fistula by coil embolization and compression of carotid artery.

We report a case of a traumatic cavernous fistula supplied by a persistent primitive trigeminal artery. The process of treatment was unique in this case. Fistula was subcompletely occluded by coiling from primitive trigeminal artery. Residual fistula was helped to form thrombosis by compression of the carotid artery with hand in the procedure. Long-term follow-up was satisfactory. Traumatic cavernous fistula supplied by a persistent primitive trigeminal artery could be treated by embolization and temporal compression of the parent artery might be useful for residual minimal fistula.
