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 ...
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
SDH can be treated with burr hole drainage, craniotomy or port system placement for blood clot evacuation, or middle meningeal artery embolisation. [ 4 ] Subdural hematoma maybe less acute than epidural hematoma due to slower blood accumulation, but it still has the potential to cause brain herniation that may require surgical evacuation. [ 3 ]
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]
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 sphenopalatine artery is the artery commonly responsible for epistaxis (difficult to control bleeding of the nasal cavity, especially the posterior nasal cavity). [3] In severe nose bleed cases which do not stop after intense packing of anti-clotting agents, the sphenopalatine artery can be ligated (clipped and then cut) during open surgery ...
