Encephaloduroarteriomyosynangiosis (EDAMS)

Encephaloduroarteriomyosynangiosis (EDAMS) is an indirect revascularization surgery for moyamoya disease or syndrome as a way to bypass an occluded internal carotid artery and circle of Willis.

It represents the combination of encephalomyosynangiosis (EMS) and encephaloduroarteriosynangiosis (EDAS) whereby superficial temporal artery branches, adjacent portions of the temporalis muscle, and subjacent galeal flap are applied under the dura directly onto the pial surface of the brain. Revascularization occurs as a result of angiogenesis driven by local hypoperfusion and ischemia ¹.
