The Subarachnoid hemorrhage (SAH) resulting from a cerebral aneurysm is featured by arterial bleeding into the subarachnoid space.
The SAH secondary to a cerebral aneurysm is an outcome of arterial bleeding into the subarachnoid space, that is, a result of aneurysm rupture. A cerebral aneurysm refers to an unusual outpouching of a blood vessel, generally an artery because of the weakness of the wall of the vessel. The majority of the cerebral aneurysms are an outcome of degenerative vessel wall injury associated with hemodynamic stresses.
