title: Dual cerebral and meningeal supply to giant arteriovenous malformations of the posterior cerebral hemisphere.
abstract: Seven cases of giant posterior hemisphere arteriovenous malformations are described. The significance of meningeal feeding vessels from the external carotid artery in addition to the primary cerebral supply through the internal carotid and vertebral arteries to these malformations is discussed. The necessity of bilateral selective external carotid arteriography is stressed, and the value of preoperative embolization is questioned.
