Cerebral Near-Infrared Spectroscopy: A Potential Approach for Thrombectomy Monitoring

Stroke; a Journal of Cerebral Circulation
Thomas RitzenthalerNorbert Nighoghossian

Abstract

Regional brain oxygen saturation (rSO2) changes, assessed by cerebral near-infrared spectroscopy, are likely influenced by cerebral hemodynamic fluctuations induced by thrombectomy of acute proximal occlusion. We studied the correlations between rSO2and baseline magnetic resonance imaging perfusion parameters and the relationship between rSO2changes, recanalization, and clinical outcome. Seventeen acute ischemic stroke patients, treated with mechanical thrombectomy, were monitored using bilateral near-infrared spectroscopy before, during, and continuously for 24 hours after the procedure. All patients had baseline brain magnetic resonance imaging with perfusion weighted imaging. rSO2was only correlated with baseline Tmax (ρ=-0.42;P<0.05) and mean transit time (ρ=-0.45;P<0.05) within forehead explored areas. Before thrombectomy, an interhemispheric rSO2difference was noted, and this diminished over time when recanalization had occurred (median [interquartile range], -8 [-12 to -5] to 3 [-3 to 7];P=0.01). rSO2changes were not correlated with clinical outcome. rSO2was merely correlated with baseline Tmax and mean transit time magnetic resonance imaging perfusion parameters. Multiple sites recording beyond frontal pole explored are...Continue Reading

Brain Ischemia

Brain ischemia is a condition in which there is insufficient blood flow to the brain to meet metabolic demand. Discover the latest research on brain ischemia here.

Acute Stroke

A stroke occurs when blood supply to the brain is interrupted depriving the brain of oxygen and nutrients. This feed focuses cerebrovascular accidents including ischemic and paralytic stroke.
