Evaluation of EDAS in Moyamoya Disease with Brain SPECT: Case Report

ABSTRACT

Moyamoya disease is characterized by progressive occlusion of major cerebral arteries and development of an abnormal vascular network. We performed EDAS(encephalo-duro-arterio-synangiosis) on 2 patients with moyamoya disease and obtained preoperative and follow-up brain SPECT to evaluate the effect of EDAS. In this study, moyamoya disease was confirmed by angiogram and the relation between the patient's clinical status and postoperative findings of SPECT was presented. In all cases, a marked increasing of blood perfusion was noticed on the implanted area together with improvement of clinical status.
