新西兰大白兔脑动脉系统的数字减影血管造影成像

目的研究新西兰大白兔脑动脉系统的特点,为建立兔脑血管疾病模型奠定基础。方法新西兰大白兔20只,采用数字减影血管造影(DSA)方法,通过新西兰大白兔股动脉将微导管导入颈内动脉近端造影,分析新西兰大白兔脑动脉系统解剖。结果颅内前后循环系统显影清楚;新西兰大白兔具有与人类相似的脑动脉系统。结论超选择性脑血管造影有利于更好地显示兔脑前后动脉系统,新西兰大白兔脑动脉系统与人类相似,为建立兔脑动脉系统血管疾病模型提供较详细的影像学基础。

Image of cerebral arterial system through digital subtraction angiography in New Zealand white rabbits

Objective To study the anatomy of Cerebral Artery System in New Zealand white rabbits and to found the imaging base for establishing cerebrovascular disease models of rabbits. Methods Catheterization of internal carotid artery in 20 New Zealand white rabbits was carried out and followed by cerebral angiography.The New Zealand white rabbits cerebral arterial anatomy was analyzed. Results The arterial system in anterior and posterior circulation was clearly visualized. The anatomy of Cerebral Arterial System in New Zealand white rabbits was similar to human brain artery. Conclusion Super-selective cerebral angiography was helpful to better display the anterior and posterior circulation in rabbits. The anatomy of Cerebral Arterial System in New Zealand white rabbits is similar to human brain artery.
