Neurological response to hyperbaric oxygen--a criterion for cerebral revascularization

Area of Science:

• Neurology
• Hyperbaric Medicine

Background:

• Cerebral infarction, often caused by carotid or middle cerebral artery occlusion, presents significant neurological deficits.
• Surgical revascularization is a potential treatment, but patient selection remains critical.

Purpose of the Study:

• To investigate the potential of hyperbaric oxygen (HBO) as a predictive tool for selecting patients with cerebral infarction who may benefit from surgical revascularization.

Main Methods:

• Twenty-two patients with cerebral infarction underwent hyperbaric oxygen therapy at 1.5 atmospheres absolute.
• Patient response, specifically motor function improvement, was monitored during HBO exposure.

Main Results:

• Ten out of 22 patients showed improved motor function during hyperbaric oxygen exposure.
• Seven patients with improved motor function underwent successful surgical revascularization with no recurrence of neurological deficit.
• Three patients who did not undergo successful revascularization experienced recurrence of neurological deficit.

Conclusions:

• Response to hyperbaric oxygen therapy can serve as a valuable indicator for identifying patients with cerebral infarction likely to benefit from surgical revascularization.
• HBO therapy may aid in optimizing patient selection for surgical intervention, potentially improving outcomes and reducing recurrence rates.
