RESUMO
Since the publication of the first edition of Korean clinical practice guidelines of secondary stroke prevention, encouraging data from recent large clinical trials and meta-analysis have led us to consider many therapeutic options in the treatment of symptomatic extracranial carotid stenosis. Accordingly, the writing group of Clinical Research Center for Stroke decided to provide recent views on the therapeutic revascularization of extracranial carotid stenosis, and timely evidence-based recommendations. In this updated version, new evidences about carotid angioplasty/stenting, treatment timing, and perioperative preparation are given, and qualifying conditions for operator are elucidated. This refinement was based on current consensus between Korean Society of Intravascular Neurosurgery, Korean Society of Interventional Neuroradiology, and Korean Society of Cerebrovascular Surgery and approved by Korean Stroke Society, Korean Neurological Association, and Korean Society of Geriatric Neurology. These recommendations are subject to future correction based on new evidences from ongoing and future studies.
