Reported 10 cases of cervical vertebral artery occlusion of the brainstem and cerebellar infarction. There were 9 males and 1 females aged from 50 to 74 years old underwent CT, MRI, CA and TCD examinations. ECG and echocardiography were used to exclude cardiogenic emboli may. The intracranial circulation is divided into three parts: 1. The proximal part: including the lower part of the cerebellum and medulla oblongata, by the intracranial vertebral artery (VA), posterior inferior cerebellar artery (PICA) branch of the blood supply. 2. Central: Including the pons and the anterior superior cerebellar artery, the branch of the anterior inferior cerebellar artery (AICA), the basilar artery (BA), and the perforating branch. 3. Distal Ministry: Including the upper part of the cerebellum, midbrain, thalamus, temporal lobe and occipital lobe, distal BA and its penetrating branch, the thalamic artery and superior cerebellar artery (SCA) and
