What Researchers Did
Researchers reported a case of a 63-year-old man who developed pneumocephalus (air trapped inside the skull) with seizures and loss of consciousness after a small dural tear during minimally invasive lumbar spinal surgery, treated with oxygen and then HBOT.
What They Found
The patient began regaining consciousness 8 hours after surgery and had full recovery by the next day. Follow-up CT showed nearly complete resolution of the pneumocephalus. HBOT was credited with accelerating absorption of intracranial gas.
What This Means for Canadian Patients
Pneumocephalus is a rare but serious complication of spinal surgery. This case suggests HBOT can rapidly resolve intracranial air. Canadian neurosurgeons and spine surgeons should be aware that HBOT is an available rescue option when pneumocephalus causes significant neurological deterioration.
Canadian Relevance
No direct Canadian connection identified.
Study Limitations
A single case report cannot confirm treatment efficacy; spontaneous resolution of pneumocephalus also occurs without HBOT, making attribution difficult.
