ABSTRACT
Background:
Middle cerebral artery (MCA) aneurysms constitute about 22% of all intracranial
aneurysms (IAs). The middle cerebral artery is the commonest location for unruptured IAs.
Ruptured MCA aneurysms are commonly associated with intracerebral hematomas.
Rebleeding has a catastrophic morbidity of up to 78%.The goal of aneurysm management is
complete, durable obliteration without neurologic consequence. Two options prevail:
endovascular emboilization and open surgical clipping.
