Biodegradable Starch Microspheres for Cerebral Arterial Embolization

Abstract

Clinical and histopathologic results suggested that: 1) consequences of cerebral embolization using biodegradable starch microspheres are related to the amount of material embolized; and 2) Spherex microspheres behave differently from degradable microspheres in the brain. Despite the rapid biodegradability of the material, permanent damage from ischemia to the brain was noted.
