Background: Emerging evidence suggests that endovascular thrombectomy is beneficial for treatment of childhood stroke, but the safety and effectiveness of endovascular thrombectomy has not been compared with best medical treatment. We aimed to prospectively analyse functional outcomes of endovascular thrombectomy versus best medical treatment in children with intracranial arterial occlusion stroke.
Methods: In this prospective registry study, 45 centres in 12 countries across Asia and Australia, Europe, North America, and South America reported functional outcomes for children aged between 28 days and 18 years presenting with arterial ischaemic stroke caused by a large-vessel or medium-vessel occlusion who received either endovascular thrombectomy plus best medical practice or best medical treatment alone.
Article Synopsis
- The study aimed to track the outcomes of patients with brain arteriovenous malformations (AVMs) who were managed conservatively, revealing key statistics on related morbidity and mortality over a 10-year period.
- Out of 1010 patients initially recruited, 434 were analyzed, with a majority having unruptured low-grade AVMs, demonstrating a 5% occurrence of serious outcomes and a higher risk in those with a history of rupture or older age.
- During the follow-up of approximately 3.2 years, 8% of patients experienced major intracranial hemorrhages, highlighting the ongoing risks associated with conservative management of AVMs.
Article Synopsis
- The study compared outcomes of mechanical thrombectomy (MT) in children with acute ischemic stroke (AIS) caused by focal cerebral arteriopathy (FCA) and cardioembolism (CE).
- Data was merged from two cohorts, analyzing factors like revascularization success and functional outcomes using standardized assessment tools.
- Results showed CE patients had better revascularization rates and potential functional outcomes compared to those with FCA, stressing the need for more research on treating pediatric strokes, especially related to FCA.
Background: Timely revascularization in acute arterial ischemic stroke (AIS) is paramount for optimal outcomes. However, factors causing treatment delays in pediatric AIS remain understudied. We investigated determinants affecting the time from symptom onset or last-known-well to the start of recanalization treatment in pediatric AIS.

Methods: This retrospective study was conducted using DWI and FLAIR extracted from the Endovascular Treatment in Ischemic Stroke image registry (2017-2021). The database was partitioned into subsets according to MRI field strength and manufacturer, and randomly divided into training set (70%) used for model fine-tuning, validation set (15%), and test set (15%).
