Cerebral Angiography

Abstract

Patients with moyamoya disease display characteristic clinical symptoms and, as discussed in Chap. 5, characteristic EEG records are also found. Definitive diagnosis, however, is possible only by means of cerebral angiography. Cerebral angiograms in moyamoya disease show various features [41, 62, 125, 136, 287, 289, 293] which are, interestingly, different in juvenile and adult cases. In juvenile cases, sequential angiograms show dynamic changes with time, but in the early stages of the disease such small changes are often overlooked. It is therefore important to understand thoroughly angiographical findings at all stages in the course of moyamoya disease.
