Evolution of brain tissue injury after evacuation of acute traumatic subdural hematomas (Reprinted from Neurosurgery, vol 55, pg 1318-1324, 2004)

Abstract

The purpose of this study was to analyze tissue biochemical patterns in the brain underlying an evacuated acute subdural hematoma to identify a characteristic pattern of changes that might indicate evolving brain injury. Prospectively collected data from 33 patients after surgical evacuation of acute subdural hematoma were analyzed.

Evolution of DTI in the area of brain underlying an evacuated subdural hematoma is associated with a significant increase in mortality. Postoperatively decreasing brain tissue oxygen tension and increasing dialysate concentrations of lactate and pyruvate in this area may warn of evolving brain injury and evoke further diagnostic and therapeutic activity.
