Summary

What Researchers Did

Researchers retrospectively reviewed the outcomes of nineteen patients treated with hyperbaric oxygen therapy (HBO2) for iatrogenic cerebral arterial gas embolism (CAGE) between 1987 and 1999.

What They Found

Immediately after hyperbaric oxygen therapy, 5 of 19 patients experienced complete resolution of symptoms, and 11 showed improvement. Within two months, an additional 3 patients fully recovered, and 6 more improved further. Patients with a venous source of CAGE consistently presented with pulmonary symptoms, with 8 out of 9 chest x-rays showing pulmonary oedema.
