Improvement and Aggravation of Spontaneous Unruptured Vertebral Artery Dissection

摘要

BackgroundIntracranial vertebral artery dissection (VAD) is a well-recognized cause of stroke in young and middle-aged individuals, especially in Asian populations. However, a long-term natural course remains unclear. We investigated the long-term time course of VAD using imaging findings to examine the rate and predisposing factors for improvement.
