Follow-up Study of ‘Moyamoya’ in Adult Patients

Abstract

The correlationship between the prognosis of the 21 adult “Moyamoya” patients and their clinical and cerebral angiographic features is reported.
Clinical and angiographical features were as follows:
1. Subarachnoideal hemorrhage was the initial symptom in 62%.
2. The prognosis was better in SAH type than in the other types.
3. The recurrence rate was 50%.
4. In SAH type, AG I type accounted for 70%, and a higher rate of AG II, III types were noted in APO and TIA types.
5. The angiographic types were much closely correlated with the prognosis than the clinical types. The cases of AG I type showed favorable prognosis and the prognosis of AG II, III types were poor. This may be attributed to the easy development of critical cerebral ischemic condition in AG III type as compared with AG I type.
