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.
