ABSTRACT
INTRODUCTION:
Large vessel occlusion-acute ischemic stroke (LVO-AIS) is infrequent in young adults and exhibits distinct stroke mechanisms compared to older adults. This study sought to evaluate the impact of varying stroke etiologies on treatment-related outcomes in young adults with LVO-AIS, an aspect that remains unclear.METHODS:
This retrospective cohort study included patients aged 18-50 presenting with AIS from January 2017 to December 2021 within our multi-center stroke network. Patients with LVO on CTA/MRA at presentation were included. We assessed demographics, stroke etiology (TOAST classification), and treatment-related outcomes. Based on intervention received, patients were divided into 5 groups [IV-thrombolysis (IVT) only, Mechanical Thrombectomy (MT) only, IVT+MT, no treatment, unsuccessful MT].RESULTS:
Among 1210 AIS patients, 220 with LVO were included. The median age was 42 (36, 46). 75 (34.1 %) patients underwent successful MT (46.7 % received IVT+MT). 26 (11.8 %) received IVT only, 110 (50 %) received neither intervention, and 9 (4.1 %) underwent unsuccessful MT. Per TOAST, 17.4 % had large artery atherosclerosis (LAA), 19.2 % cardio-embolism, 28.6 % stroke of other etiology, and 34.7 % had undetermined etiology. Favorable thrombectomy outcomes (TICI 2b/2c/3) were observed in 87.2 %. Discharge NIH Stroke Scale (NIHSS) scores improved for patients with IVT+MT in all TOAST categories except LAA.CONCLUSIONS:
Young adults with LVO-AIS had good outcomes irrespective of stroke etiology, except LAA, which was associated with a higher discharge NIHSS. Moreover, 50 % of young adults in our study received no intervention, a quarter of those owing to delayed presentation. Further studies are needed to identify barriers in seeking acute treatment in young adults with LVO-AIS.
