Original description
Patients with ischemic stroke in the posterior circulation continue to have high rates of mortality and disability, even with aggressive treatment. We wanted to evaluate preoperative imaging to screen patients with a good prognosis from mechanical embolization. We assess the degree of ischemia by defining the pons-midbrain-medulla index (PMMI) and correlate the preoperative PMMI with the clinical prognosis of postoperative patients to verify the validity of PMMI in predicting the clinical prognosis of patients with embolization.Read full original descriptionShow less

Medical Imaging Screening for Posterior-circulation Ischemic Stroke：a Multicentre,Imaging-based,Prospective Cohort Study

Patients with ischemic stroke in the posterior circulation continue to have high rates of mortality and disability, even with aggressive treatment. We wanted to evaluate preoperative imaging to screen patients with a good prognosis from mechanical embolization. We assess the degree of ischemia by defining the pons-midbrain-medulla index (PMMI) and correlate the preoperative PMMI with the clinical prognosis of postoperative patients to verify the validity of PMMI in predicting the clinical prognosis of patients with embolization.

Inclusion: Patient admitted from Jun. 1st 2019 to Jan. 1st 2029; Patients with acute ischemic stroke recently；; Symptoms persisted at admission, and MRI (including DWI) confirmed acute ischemic vertebrobasilar artery occlusion in the posterior circulation:（single right or left intracranial branch of vertebral artery occlusion ; single basilar occlusion ; both two vertebral arterys and basilar artery）；.

Exclusion: 1.Patiens can not meet the MRI examination conditions(with absolute and relative contraindications).
