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 ...
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 ...
Epidural hematoma commonly results from a blow to the side (temporal bone) of the head. The pterion region, which overlies the middle meningeal artery, is relatively weak and prone to injury. [10] Only 20 to 30% of epidural hematomas occur outside the region of the temporal bone. [11]
The second procedure, a middle meningeal artery embolization, was aimed at minimizing the risk of future bleeding. "The procedure was successful. We managed to embolize that artery," Kalil said ...
Membranes with granulation tissue can rupture within SDH, and give high density appearance on CT scan. Over a prolonged period of time, calcifications can form. SDH can be treated with burr hole drainage, craniotomy or port system placement for blood clot evacuation, or middle meningeal artery embolisation. [4]
Between the skull and the inner meningeal layer of the dura mater or between outer endosteal and inner meningeal layer of dura mater: Between the meningeal layers of dura mater and the Arachnoid mater: Involved vessel Temperoparietal locus (most likely) – Middle meningeal artery Frontal locus – anterior ethmoidal artery
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.
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 ...
