Pseudohypoxic Brain Swelling (Postoperative Intracranial Hypotension-Associated Venous Congestion) After Spinal Surgery: Report of 2 Cases

Abstract

Pseudohypoxic brain swelling should be considered in patients with unexpected neurological deterioration after spinal surgery. It might be a form of postoperative intracranial hypotension-associated venous congestion, which should be distinguished from common postoperative cerebral ischemic events caused by arterial or venous occlusions.
