【摘要】 在原有脑梗塞动物模型的基础上加大了栓子的直径和注栓压力,使大脑中动脉干枝总栓塞率提高到93.75％,单纯干枝栓塞率为71.88％。这样对进一步形成脑梗塞的病灶定位理应更加稳定。更多还原

【Abstract】 Based on the authors’ previously reported animal model of cerebral infarction in mongrel dog, this work is designed to establish a more stable method to obtain the main trunk embolization of middle cerebral artery. Diameter of the emboli were increased to 0.93±0.03mm, and the injection force enhanced up to 68±kPa. It was able to harvest a total embolization rate of the main trunk of the middle cerebral artery to 93.7% , and an exclusive embolization rate to 71.9%. Accordingly, upon the specific embolization of the main trunk of the middle cerebral artery, the localization stability of the imfarction foci in the future developing infarction model might be expected to be improved significantly.更多还原
