The middle meningeal artery is the largest of the three (paired) arteries that supply the meninges, the others being the anterior meningeal artery and the posterior meningeal artery. The anterior branch of the middle meningeal artery runs beneath the pterion. It is vulnerable to injury at this point, where the skull is thin. Rupture of the ...
It may result from laceration of an artery, most commonly the middle meningeal artery. This is a very dangerous type of injury because the bleed is from a high-pressure system and deadly increases in intracranial pressure can result rapidly. However, it is the least common type of meningeal bleeding and is seen in 1% to 3% cases of head injury.
The anterior division of the middle meningeal artery runs underneath the pterion. [4] Consequently, a traumatic blow to the pterion may rupture the middle meningeal artery causing an epidural haematoma. The pterion may also be fractured indirectly by blows to the top or back of the head that place sufficient force on the skull to fracture the ...
The cause is typically a head injury that results in a break of the temporal bone and bleeding from the middle meningeal artery. [4] Occasionally it can occur as a result of a bleeding disorder or blood vessel malformation. [1] Diagnosis is typically by a CT scan or MRI scan. [1]
Arterial injuries results in more rapidly growing hematoma when compared to venous injuries. [3] At the pterion region, middle meningeal artery is most commonly affected. When fracture is crossing areas where dural venous sinuses resides, venous hemorrhage can occur such as falx cerebri , tentorium cerebelli , and vertex (where superior ...
A post mortem study of middle cerebral artery strokes demonstrated that the area of brain injury was often smaller than the total area supplied by the middle cerebral artery. Leptomeningeal collateral vessels from the anterior cerebral artery and posterior cerebral artery appeared to allow for perfusion of some brain tissue to persist ...
Meningeal artery may refer to Anterior meningeal branch of anterior ethmoidal artery; Meningeal branches of vertebral artery; Middle meningeal artery;
This depends upon the area of the cranial cavity: in the anterior cranial fossa the anterior meningeal artery (branch from the ethmoidal artery) is responsible for blood supply, in the middle cranial fossa the middle meningeal artery and some accessory arteries are responsible for blood supply, the middle meningeal artery is a direct branch ...
