摘要头颈部动脉夹层是脑卒中的少见病因，准确的诊断、合理的治疗、积极的预防是改善其预后的重要措施。随着国内外头颈部动脉夹层诊疗临床研究的不断深入，新的循证医学证据陆续出现，特别在高分辨率磁共振成像对头颈部动脉夹层的诊断、夹层相关抗栓治疗及血管内治疗等方面有了新的进展。正确的诊断和规范的治疗是改善头颈部动脉夹层预后的重要措施。在近9年来我国的临床实践和国内外相关的循证医学证据以及《中国颈部动脉夹层诊治指南2015》的基础上，中华医学会神经病学分会及其脑血管病学组组织专家制订了《中国头颈部动脉夹层诊治指南2024》，为中国神经科医生建立合理的头颈部动脉夹层诊断思路以及临床治疗和预防策略给予参考和指导。

abstractsCervicocranial artery dissection (CcAD) is a rare etiology of stroke. Accurate diagnosis, reasonable treatment and effective prevention are particularly important for the prognosis. With the development of clinical research on CcAD, more and more evidence-based medical data provide guidance for clinical diagnosis and treatment, especially in the use of high-resolution magnetic resonance imaging for diagnosis and anti-thrombotic therapy, endovascular treatment, etc. Chinese Society of Neurology and Chinese Stroke Society organized experts to formulate the Chinese guidelines for diagnosis and treatment of cervicocranial artery dissection 2024 based on the Chinese guidelines for diagnosis and treatment of cervical artery dissection 2015 and relevant evidence-based medical evidence both domestically and overseas as well as clinical practice in China in recent 9 years. The purpose of the guidelines is to provide reasonable diagnosis, treatment and prevention strategies for CcAD.
