What Researchers Did
Doctors described the case of a 34-year-old man who had a stroke after receiving ozone gas injections near his neck for chronic neck pain.
What They Found
This case report describes a man who developed multiple strokes after gas bubbles entered his vertebral artery following a paravertebral ozone injection. After his last injection he had a fainting episode, and when he woke up he had poor coordination, difficulty speaking, weakness on one side, and a nerve palsy affecting eye movement. Imaging showed gas within the right vertebral artery and multiple strokes in the back part of his brain.

Study Limitations
This is a single case report, so it cannot show how often this complication occurs or what causes it in general, and its findings may not apply to other patients or procedures.
