Objective: By comparing learning and memory ability, postoperative mortality and changes of hippocampus tissue for different vascular dementia model, we investigate the feasibility of modified bilateral carotid artery ligation dementia model with small incision, which constructs the objective basis for the establishment of vascular dementia model with simple operation and low mortality. Method: After being screened by the water maze, 36 male SD rats were randomly divided into sham group, small incision double permanent ligation group and stagin...
