Effect of Indirect Cerebrovascular Anastomosis in Adult Moyamoya Patients

Abstract

This is a report of 6 adult patients of moyamoya disease. We discuss the effects of the indirect cerebrovascular anastomosis.
Two of these patients, presented with ischemia and the other 4 presented with hemorrhage.
The postoperative follow-up ranged from 18 months to 105 months. Two hemorrhagic patients showed rebleeding. In patients who presented with ischemia, adequate neovascularization and prevention of recurrence were obtained with indirect cerebrovascular anastomosis. However, in patients who presented with hemorrhage, this indirect operative method gave unsatisfactory results.
