subdural and epidural hemorrage are caused by head trauma, while subarachnoid is caused by rupture of a berry aneurysm this most likely related to polycystic kidney dx.
subdural=rupture of bridging veins
epidural= rupture of middle meningeal artery

Also epidural hematoma, would results in feeling fine at first and then after a couple of hours, losing consciousness, and possibly going into a coma, which is not seen with subdural, whose effects takes a while to develop.

well the cidcle of willis is formed by two main arteries
1...internal carotid
2...vertebral artery
the internal carotid begins in the neck at the bifurcation of common carotid a..ascens in nec nd thru the carotid canal of temporal bone into the skull where it runs horizontaly forward thru the cavernous sinus
the vertebral artery is the branch of first part of suncavian a...it ascends thru the foramina in th e transverse processes of the upper six cervical vertebrae..at lower border of pons joins te vessel of opp side to form basilar a...
is tht enough?
