Non hypertensive inter cranial hemorrhages Flashcards
What are examples of non-hypertensive intracranial hemorrhages?
Intraparenchymal -amyloid angiopathy (ApoE)
Subarachnoid - saccular aneurysms (berry anuerysym)
Subdural and epidural hematomas
Vascular malformations Emboli: bone marrow/fat (long bone fracture) Atherosclerotic aneurysm, rupture
What is the most common cause of Subarachnoid hemorrhage?
