Abstract
Preoperative and postoperative angiograms of a 13-year-old Japanese girl with moyamoya disease are compared. She underwent an indirect extracranial/intracranial bypass operation called encephaloduroarteriosynangiosis (EDAS). Post-EDAS angiograms clearly show revascularization of the brain through the donor scalp artery and decrease in moyamoya vessels, leptomeningeal anastomoses, and preexisting spontaneous transdural anastomoses.
