Middle cerebral artery aneurysm outcome
In patients with MCA aneurysms, clinical outcomes at 1 year are similar between microsurgical clipping and endovascular therapy. However, microsurgery is associated with a lower risk of residual aneurysms 1) 2).
Random forest modeling is a good tool for evaluating the rupture status of Small middle cerebral artery aneurysm and may be considered for the management of Small intracranial aneurysms 3).
Primary decompressive craniectomy (vs. craniotomy) for poor-grade MCA aneurysm SAH (WFNS IV/ V) with associated IPH (>30cc) has not shown to provide any survival benefit and is not associated with improved outcome 4).
