Increased arterial pulsatility and progression of single subcortical infarction

ConclusionsHigher pulsatility was associated with progression in lacunar infarction. PI measured by transcranial Doppler sonography might reflect downstream arterial resistance and vascular/paravascular perfusion status and be a possible indicator of stroke progression.Key Points•Higher pulsatility index was observed in progression group of lacunar infarction patients.•Higher pulsatility index seemed to be associated with progression in lacunar infarction patients.•Differences in the factors associated with stroke progression suggest different underlying pathophysiologies.
