What Researchers Did
Researchers reviewed all reported cases of cerebral air embolism (CAE) following percutaneous kyphoplasty (a minimally invasive spine procedure) and added a new case of an 84-year-old man who developed the complication after surgery for a spinal fracture.
What They Found
Only 7 cases of CAE after spinal surgery have ever been reported. In all three patients who received HBOT, survival was achieved, though the new case resulted in a persistent vegetative state despite treatment. Air entered the bloodstream through vertebral defects and surgical instrument placement. The review proposes a prevention protocol involving pre-surgery imaging to detect spinal defects, careful instrument insertion, and immediate HBOT after diagnosis.
What This Means for Canadian Patients
While extremely rare, air embolism after spinal procedures is catastrophic and requires immediate action. This review reinforces that hospitals offering vertebral augmentation procedures should have a clear protocol for recognizing and treating CAE, including urgent access to HBOT. Canadians undergoing kyphoplasty or similar procedures should be aware of this rare but serious risk.
Canadian Relevance
Arterial gas embolism is an OHIP-covered indication for HBOT in Ontario; this case series directly supports maintaining rapid-access hyperbaric treatment for post-surgical gas embolism events.
Study Limitations
With only 7 total cases worldwide, this report cannot determine how often HBOT prevents permanent disability versus how often damage is already irreversible by the time treatment begins.
