Pseudohypoxic brain swelling following elective lumbar laminectomy: A rare case report and review of literature – Lumbar Spinal Stenosis

The article discusses a case of pseudohypoxic brain swelling, a rare complication that can occur after neurosurgical procedures. The case involves a 73-year-old female patient who developed this complication following an elective L4-L5 laminectomy, despite no evidence of cerebrospinal fluid leakage during the surgery. The patient initially presented with symptoms resembling anoxic/hypoxic brain injury, but the case deviated from typical patterns of pseudohypoxic ischemic venous hypertension (PIHV), making the diagnosis challenging. However, the patient experienced a remarkable recovery, highlighting the importance of considering PIHV in differential diagnoses when postoperative symptoms mimic brain injuries. The case emphasizes the need for comprehensive postoperative surveillance and management, and highlights the importance of further research into the pathophysiology and treatment strategies for PIHV

ABSTRACT

Pseudohypoxic brain swelling, also known as postoperative intracranial hypotension-associated venous congestion, is an intriguing complication following routine neurosurgical interventions. We report a case of a 73-year-old female patient who exhibited this rare complication following an elective L4-L5 laminectomy, without evidence of intraoperative cerebrospinal fluid leakage. Initially presenting with clinical features suggestive of anoxic/hypoxic brain injury, the case deviated from typical pseudohypoxic ischemic venous hypertension (PIHV) patterns, leading to a challenging diagnostic process. The patient’s remarkable recovery, contrary to the initial grim prognosis, emphasizes the critical need for considering PIHV in differential diagnoses when postoperative symptoms mimic anoxic/hypoxic brain injuries. This case contributes to the evolving understanding of PIHV, particularly in scenarios lacking conventional risk factors like cerebral spinal fluid (CSF) leakage, and underscores the importance of comprehensive postoperative surveillance and management. It also highlights the imperative for continued research into the pathophysiology and treatment strategies of PIHV to enhance patient outcomes in complex surgical contexts.
