Superficial temporal artery to middle cerebral artery (STA-MCA) bypass is a form of direct revascularization most commonly performed for moyamoya disease, or rarely for intracranial atherosclerotic disease (ICAD), whereby the superficial temporal artery is dissected, passed though a craniotomy/burr hole 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.
