Can cerebral revascularization prevent hemorrhaic event in moyamoya disease? ; Message from the clinics(Radiological observation of moyamoya disease)

초록

Objective ; Moyamoya disease, characterized with cerebrovascular asteriopathy causing progressive narroeing of Intracranial ICA, can cause cerebral hemorrhage. We performed this study to clear the sources of hemorrhagic events and to evaluated the possible effectiveness of revascularization for its prevention Method ; The authors reviewed the clinical and radiologic records obtained in a consecutive series of 126 pts with M syndrome. Result ; thirty two pts had presented with cerebral hemorrhage and 91 had been presented with cerebral ischemia. Three pts had been presented with both. Hemorrhagic occurred mainly in the ventricle(14 pts), thalamus(9), and basal ggl(6), where maximal hemodynamic loading existed. Conclusion ; considering that most hemorrhagic events had occurred around the maximal hemodynamic loading area such as the junction between ventripetal artery and ventrifugal dysplastic artery and such dysplastic astery had been disappeared after extensive revascularization.
