The middle meningeal vein parallels the path of the middle meningeal artery. The vein emerges from the maxillary vein via the pterygoid plexus. A venous plexus is a collection of veins. The maxillary vein joins with the superficial temporarl vein to become the retromandibular vein. The retromandibular joins with the posterior auricular vein to create the external jugular vein. That vein drains into the subclavian vein. Most epidural hematomas are caused by skull fractures that cross either the middle meningeal artery or the middle meningeal vein. This problem with the artery occurs in 60 percent of these types of cases. Venous epidural hematomas are mostly a problem in children. They are not as often caused by skull fractures. One possible complication is a fistula between the middle meningeal artery and the middle meningeal vein. One such case was reported involving a 21-year old man with head injuries from a car accident. He had head contusions, a skull fracture, and bleeding. He was successfully treated, but one year later, an angiogram indicated a dural arteriovenous fistula. It originated in the middle meningeal artery and drained into the middle meningeal vein. It was successfully treated with a transarterial embolization.
