Cerebral hemodynamic characteristics of acute mountain sickness upon acute high-altitude exposure at 3,700 m in young Chinese men

Purpose We aimed at identifying the cerebral hemodynamic characteristics of acute mountain sickness (AMS). Methods Transcranial Doppler (TCD) sonography examinations were performed between 18 and 24 h after arrival at 3,700 m via plane from 500 m ( n = 454). A subgroup of 151 subjects received TCD...

Zusammenfassung:	Purpose We aimed at identifying the cerebral hemodynamic characteristics of acute mountain sickness (AMS). Methods Transcranial Doppler (TCD) sonography examinations were performed between 18 and 24 h after arrival at 3,700 m via plane from 500 m ( n = 454). A subgroup of 151 subjects received TCD examinations at both altitudes. Results The velocities of the middle cerebral artery, vertebral artery (VA) and basilar artery (BA) increased while the pulsatility indexes (PIs) and resistance indexes (RIs) decreased significantly (all p
