摘要:
【摘要】 目的 评估通过小鼠右侧颈总动脉途径灌注对比剂Microfil显示Willis环的可行性和效果。方法 选取20只雄性C57BL/6小鼠(约14周龄,重约20 g)。将小鼠肝素化、麻醉后固定、解剖胸腔,依次自小鼠心尖灌注0.9%氯化钠溶液、4%多聚甲醛溶液和2%戊二醛溶液混合液;分离右侧颈总动脉,经右侧颈总动脉近端灌注Microfil,4℃过夜;取脑后体视镜下观察Willis环。将体视镜下观察到的Willis环定义为完全充盈、大部分充盈和充盈不良。结果 20只小鼠全部灌注成功,其中完全充盈11只(55%),大部分充盈4只(20%),充盈不良5只(25%)。大体观察小鼠Willis环完整,染色血管清晰;体视镜下Willis环充盈、立体。结论 通过小鼠右侧颈总动脉途径灌注Microfil显示Willis环方法简单、可行,不仅能使Willis环充盈良好,还能清晰显示其立体结构,具有MRA成像效果。
