Encephaloduroarteriosynangiosis
Encephaloduroarteriosynangiosis (EDAS)
Encephaloduroarteriosynangiosis (pronunciation: en-sef-uh-lo-dur-o-arterio-syn-angiosis) is a surgical procedure used to treat Moyamoya disease and other conditions that reduce blood flow to the brain.
Etymology
The term "Encephaloduroarteriosynangiosis" is derived from the Greek words 'Encephalo' (brain), 'Duro' (hard, referring to the dura mater), 'Arterio' (artery), and 'Synangiosis' (creation of a new connection).
Procedure
In an EDAS procedure, a surgeon makes an incision in the scalp and lays a branch of the external carotid artery on the surface of the brain. The artery is then stitched into place, and the scalp is closed. Over time, new blood vessels form, providing increased blood flow to the brain.
