Clinical trials

This study will compare the efficacy and safety of the transradial approach versus the transfemoral approach for performing full cerebral angiography. Participants will undergo cerebral angiography via one of the two approaches and will be followed up during and after the procedure. The primary endpoint of this study is to evaluate the success rate of completing full cerebral angiography (including superselective catheterization of bilateral common carotid arteries, subclavian arteries near the vertebral artery origin, and the aortic arch) via the transradial approach versus the transfemoral approach. During the study, the medical team will also document procedural details, incidence of complications, patient comfort, and related costs to comprehensively evaluate the clinical performance differences between the two approaches.

This observational study aims to investigate the real-world effectiveness and safety of different treatment strategies for acute ischemic stroke (AIS) in Chinese children under 18 years of age. Its primary research question is: In real-world clinical practice, does endovascular therapy (e.g., stent retriever thrombectomy, aspiration thrombectomy) improve 90-day functional outcomes in pediatric AIS patients with acute anterior or posterior circulation large vessel occlusion? Children under 18 years of age receiving routine AIS diagnosis and treatment at approximately 25-35 study centers across China will undergo neurological function assessments, imaging examinations, and evaluations of growth, development, and psychosocial status at baseline, 24 hours post-procedure, 7 days post-procedure or at hospital discharge, and at 90 days and 6 months post-onset. Adverse events will also be documented.
