What Researchers Did
Researchers presented a case report on a 25-year-old man who received hyperbaric oxygenation for steroid-refractory radiation-induced oedema following stereotactic radiosurgery.
What They Found
Five months after radiosurgical retreatment for an arteriovenous malformation, the patient developed oedema and hemiparesis, which did not respond to high-dose steroids. Following a course of 25 hyperbaric oxygenation treatments, his oedema and hemiparesis improved within one month, enabling steroid reduction. A one-year follow-up revealed complete thrombosis of the arteriovenous malformation and minimal neurological deficit.
Canadian Relevance
This study has no direct Canadian connection.
Study Limitations
The primary limitation of this study is its nature as a single technical case report, which restricts the generalizability of its findings.
