In the present study, the investigators use high-resolution MR vessel wall imaging, and select patients with cerebral and cervical artery occlusion to investigate the relationship between the imaging appearance of thrombus and the various outcome of recanalization treatment.

Cerebral ischemic stroke resulting from thrombosis causes high disability and mortality. There are few biomarkers to evaluate arterial thrombophilia until now. Previous studies have demonstrated that atherosclerotic plaque rupture and erosion are major etiologies initiating thrombosis. Based on previous works targeting the role of plaque and blood flow in cerebrovascular disease, in the present study, the investigators use high-resolution MR vessel wall imaging, and select patients with cerebral and cervical artery occlusion to explore the relationship between the imaging appearance of thrombus and the various outcome of recanalization treatment. The study's objective was to solve the challenges in the mechanism of thrombus features and the outcome of recanalization therapy, thus helping improve the primary and secondary prevention of cerebrovascular disease.
