description | We sought to investigate the capacity of cerebral autoregulation and cerebrovascular reactivity (CVR) in patients with middle cerebral artery (MCA) stenosis.
Twenty-one patients with MCA stenosis diagnosed by magnetic resonance angiography and 15 healthy controls were enrolled. Cerebral autoregulation was assessed by autoregulatory parameters (rate of recovery/phase/gain) derived from transfer function from spontaneous oscillations of cerebral blood flow velocity and blood pressure. CVR was tested by a rebreathing maneuver.
Rate of recovery, phase and CVR estimated from moderate MCA stenosis (rate of recovery = 17.76 ± 8.21%/s, phase = 26.93 ± 15.67°, and CVR = 1.53 ± 0.84%/mmHg, respectively) were significantly different (p |
