What Researchers Did
Researchers conducted neurological and EEG-analytical follow-up examinations over 3.5 years in 73 patients with carotid artery occlusion after a completed stroke, treating all with hyperbaric oxygenation and 38 cases additionally with extra-intracranial arterial bypass surgery.
What They Found
The findings indicated that chronic ischaemic alterations of the brain could be improved by hyperbaric oxygenation therapy. Additional recovery was observed in the 38 patients who also underwent subsequent extra-intracranial arterial bypass operation, suggesting a potential benefit of combined treatment for these 73 patients.
Canadian Relevance
This study has no direct Canadian connection as indicated by the metadata.
Study Limitations
A significant limitation is the absence of a control group, making it difficult to definitively attribute the observed improvements solely to the interventions rather than natural recovery or other factors.
