Overview
The objective of this study is to create a comprehensive, real-world, multi-center observational registry of consecutive patients admitted to hospitals with acute ischemic stroke (AIS) caused by large vessel occlusions (LVO), who are treated with either endovascular therapy (EVT) or the best available medical management (BMM).
Description
The TRACK-LVO registry is an observational study conducted across multiple centers with the aim of improving the detection and treatment of large vessel occlusion (LVO) in acute ischemic stroke (AIS) patients. LVO is a major predictor of unfavorable outcomes in stroke patients, and the most effective imaging modalities for its detection remain a topic of debate.
To address this, the investigators will enroll consecutive AIS patients with LVO screened under different imaging modalities and compared the efficacy of endovascular therapy (EVT) and best medical management (BMM). The registry defines LVO as an occlusion of the intracranial ICA with or without the involvement of the terminal bifurcation, M1 and/or M2 segment of the MCA, A1 and/or A2 segment of the ACA, VA, BA, or P1 and/or P2 segment of the PCA. Patient information, including basic demographic profiles, imaging characteristics such as volume of ischemic core and occlusion site, and treatment-related complications will be collected for both EVT and BMM groups. For patients in the EVT group, detailed information on the EVT procedure and angiographic images will also be collected.
The study aims to identify the optimal imaging modalities for LVO detection and to compare the prognosis of AIS patients with LVO receiving EVT versus BMM. This academic, real-world, multi-center, observational registry will contribute valuable insights to improve the detection and treatment of LVO in AIS patients, ultimately improving patient outcomes and reducing the burden of stroke on public health and socio-economic development.
