STA-MCA bypass

Superficial temporal artery to middle cerebral artery (STA-MCA) bypass is a form of direct revascularization most commonly performed for moyamoya disease or intracranial atherosclerotic disease whereby the superficial temporal artery is dissected, passed though a craniotomy/burrhole and directly anastomosed to a branch of the middle cerebral artery 1.  

Generally, and especially in children who have smaller vessels, indirect revascularization procedures such as encephaloduroarteriosynangiosis (EDAS)encephalomyosynangiosis (EMS) or encephaloduroarteriomyosynangiosis (EDAMS) are considered safer 1
