Abstract

Background and purpose: Parent artery atherosclerosis is an important aetiology of recent subcortical ischaemic stroke (RSIS). However, comparisons of RSIS with different degrees of parent artery atherosclerosis are lacking. Methods: Prospectively collected data from our multicentre cohort (all were tertiary centres) of the Stroke Imaging Package Study between 2015 and 2017 were retrospectively reviewed. The patients with RSIS defined as a single clinically relevant diffusion‐weighted imaging positive lesion in the territory of lenticulostriate arteries were categorized into three subgroups: (1) normal middle cerebral artery (MCA) on magnetic resonance angiography and high‐resolution magnetic resonance imaging (HR‐MRI); (2) low‐grade MCA atherosclerosis (normal or <50% stenosis on magnetic resonance angiography and with MCA plaques on HR‐MRI); (3) steno‐occlusive MCA atherosclerosis (stenosis ≥50% or occlusion). The primary outcome was 90‐day functional dependence (modified Rankin Scale score >2). The clinical and imaging findings were compared between subgroups. Results: A total of 239 patients (median age 60.0 [52.0–67.0] years, 72% male) were enrolled, including 140 with normal MCA, 64 with low‐grade MCA atherosclerosis and 35 with steno‐occlusive MCA atherosclerosis. Patients with steno‐occlusive MCA atherosclerosis had the largest infarct volume. Low‐grade MCA atherosclerosis was independently associated with cerebral microbleeding, more severe perivascular spaces in basal ganglia and higher total cerebral small vessel disease burden. Low‐grade MCA atherosclerosis was an independent determinant of 90‐day functional dependence (odds ratio 3.897; 95% confidence interval 1.309–11.604). Conclusions: Our study suggested RSIS with varying severity of parent artery atherosclerosis exhibits distinctive clinical and neuroimaging characteristics, with low‐grade MCA atherosclerosis associating with higher cerebral small vessel disease burden and worse prognosis.
