Wu Y, Wu F, Liu Y, et al. - In this systematic review, researchers used multiple logistic regression to examine the features of cervicocranial artery dissection (CCAD) on high-resolution MRI that are linked to acute ischemic stroke. Patients with CCAD were recruited and divided into stroke and non-stroke groups. For this investigation, the researchers reviewed the lesion location, the presence of a double lumen, intimal flap, intramural hematoma, pseudoaneurysm, irregular surface, intraluminal thrombus, and other quantitative parameters of each dissected segment. In total, 145 affected vessels from 118 patients with CCAD were analyzed. In patients with CCAD in whom a stroke had occurred, anterior circulation, intramural hematoma, irregular surface, intraluminal thrombus, and severe stenosis (> 70%) on high-resolution MRI were more prevalent. In patients with CCAD, the presence of irregular surface and intraluminal thrombus were associated with stroke occurrence. High-resolution MRI could provide insight into ischemic stroke pathogenesis in CCAD, and may be helpful for individual anticipation of ischemic stroke early in CCAD.
