Endovascular treatment for dural arteriovenous fistulas at the jugular foramen.

We report the technique and results of the endovascular treatment of jugular foramen dural arteriovenous fistulas (DAVFs) in 4 (3 men and 1 women, mean age 50.75 years) symptomatic patients. The jugular foramen DAVFs accounted for 5.9% of intracranial DAVFs. Three patients presented with pulsatile tinnitus and 1 patient presented with intracranial hemorrhage. Angiography demonstrated an AV fistula at the jugular foramen, mostly arising from the middle meningeal, ascending pharyngeal and vertebral arteries with direct drainage to the internal jugular vein. All patients underwent transarterial embolization using Onyx-18. Complete shunt obliteration was achieved in 3 patients; and shunt reduction, in 1 patient, who was cured with additional surgery. Our study suggests that in jugular foramen DAVF transarterial embolization with Onyx should be considered when access is available.
