This study used high resolution vessel wall imaging to investigate the lenticulostriate artery (LSA) morphology and plaque characteristics in three patient groups: single small subcortical infarction (SSI) with/without plaque on the parental artery, and large subcortical infarction with large artery atherosclerosis (LAA) as reference. SSI with plaque (SUD) on the parental artery manifested more like LAA, having relatively lower total CSVD score and lower number and total length of LSA branches. However, the plaques in SUD were mainly positive remodeling. These findings reinforce our understanding about the etiology of SSI with plaque on the parental artery.
