Indication of Reconstructive Operation for Moyamoya Disease and Ideal Operative Methods

Abstract

The authors experienced 12 operative cases of moyamoya disease and the following conclusion was obtained.
A) As to indication of reconstructive operation:
1. Best indication: TIA or RIND or completed stroke with minor neurological deficits
2. Preferable indication : Cerebral hemorrhage and/or intraventricular hemorrhage with minor neurological deficits
3. No indication at the present time: Incidentally discovered, headache only, seizure only, mental retardation in adults
B) As to ideal operative methods:
STA-MCA bypass with encephalo-myo-synangiosis seemed to be the most preferable operative methods. In addition, usefulness of encephalo-arterio-synangiosis (EAS) as a supplemental operative method was emphasized.
