Effect of stenting on cerebrovascular reactivity in patients with symptomatic middle cerebral artery stenosis
Abstract:Objective To observe the effect of stenting on cerebrovascular reactivity (CVR) in patients with severe symptomatic middle cerebral artery (MCA) stenosis.Motheds Ten patients (6 males 4 femals) with unilateral severe symptomatic MCA stenosis aged 61-73 years were included in this study.Their cerebral blood flow (CBF) was measured by CTP before and after 5%CO2and 95%O2 inhalation and their CVR was assayed.The CVR was assayed once more 6 months after the patients with decreased CVR underwent stenting.The CVR was compared before and after stenting.Results The 10 patients included in this study who underwent successful stenting were followed up.Their CVR was-14%--29% before stenting and was-2%-24% after stenting.Of the 10 patients,8 had no improvement in their CVR and 2 became normal in their CVR.Conclusion Stenting can improve the CVR in patients with unilateral severe MCA stenosis.
