What Researchers Did
Researchers conducted a preliminary study on two patients with cerebral radionecrosis following Gamma Knife radiosurgery to evaluate the efficacy of hyperbaric oxygen therapy.
What They Found
Both patients responded well to hyperbaric oxygen therapy, with one lesion disappearing completely and the other significantly reduced in size. This occurred after 40 sessions of breathing 100% oxygen at 2.5 atmospheres absolute, without the use of adjuvant steroids.
Canadian Relevance
This study has no direct Canadian connection as it was not conducted in Canada, nor did it involve Canadian researchers or patients.
Study Limitations
The primary limitation of this study is its very small sample size of only two patients, making the findings preliminary and requiring further confirmation.
