Occlusive Cerebrovascular Disease with Moyamoya Vessels and Intracranial Hemorrhage during Pregnancy

—Case Report and Review of the Literature—

Abstract

A 24-year-old female in the sixth month of pregnancy developed headache and vomiting caused by an intraventricular hemorrhage from moyamoya vessels. Superficial temporal artery-middle cerebral artery bypass surgery was performed when she was in the seventh month of pregnancy in order to prevent intracranial rebleeding or a cerebrovascular ischemic attack during labor and delivery. The patient delivered successfully at full term, without complications. The clinical features and management of patients with such rare occurrences during pregnancy are discussed and seven previously reported cases are reviewed.
