Abstract

An operation to place the temporal muscles on the brain surface, namely EncephaloMyo Synangiosis, was carried out on 10 patients with “Moyamoya” disease lacking the middle cerebral artery on the brain surface for anastomosis.
Postoperative superselective deep temporal angiogram proved the development of rich vascular supply from the temporal muscle to the brain surface. Satisfactory clinical improvements were seen in nine patients. The remaining one child with transient ischemic attacks (TIA) and major neurological deficits showed slight improvement in spite of being unable to take care of himself. The other nine patients also showed improved electroencephalographic findings. Significant blood supply through the external carotid system to the operated area of the brain was shown in some cases by appearance of diffuse slow activity when the common carotid artery on the same side was compressed.
