A Clinical Study of iEPC Intervent Subjects With Cerebral Hemorrhagic Stroke

1. Subjects ≥ 18 and ≤ 80 years of age

2. Subjects was confirmed cerebral hemorrhagic stroke, included at least one of risk factors(Hypertension, diabetes, coronary heart disease, high blood lipid), and Satisfied with one of the following conditions:

   A. Significant stenosis (> 50%) of the intracranial and extracranial arteries or their branches due to atherosclerosis, or clinical or imaging manifestations of vascular blockage B. Head imaging (CT or MRI) : cerebral hemispheric infarct lesion diameter of > 1.5cm; Or there were more than 2 discontinuous lesions in the blood supply area of the same intracranial external artery.

   C. Auxiliary examination: color ultrasonography, CTA, MRA or DSA of the blood vessels in the neck confirmed that the intracranial or extracranial stenosis was greater than or equal to 50%；
