Experimental Cerebral Fat Embolism: Distribution of Radioactive Triolein Following Internal Carotid Introduction

Experimental Cerebral Fat Embolism: Distribution of Radioactive Triolein Following Internal... Abstract Injection of radioactive fat emboli into the internal carotid artery of rabbits resulted in rapid death in some animals. Death was preceded by hypertension and Cheyne-Stokes respirations. These animals showed an increased retention of fat emboli within the brain, and a disproportionately high recovery from the pons and midbrain, compared to animals which were killed. The data suggest that the death mechanism was brain stem ischemia followed by a vasomotor ischemic reflex, which in turn resulted in vasospasm and hypertension. The choroid plexus was found to be the most efficient filter for fat emboli within the brain on a per gram basis. References 1.

Abstract

Abstract Injection of radioactive fat emboli into the internal carotid artery of rabbits resulted in rapid death in some animals. Death was preceded by hypertension and Cheyne-Stokes respirations. These animals showed an increased retention of fat emboli within the brain, and a disproportionately high recovery from the pons and midbrain, compared to animals which were killed. The data suggest that the death mechanism was brain stem ischemia followed by a vasomotor ischemic reflex, which in turn resulted in vasospasm and hypertension. The choroid plexus was found to be the most efficient filter for fat emboli within the brain on a per gram basis. References 1.
