观察中国实验用小型猪（ＣＥＭＰ）头颈血管影像并探讨其应用。方法对ＣＥＭＰ行头颈血管造影，分析其影像并与人的影像相比较。结果猪无颈内动脉颅外段，代之以咽升动脉，后者在海绵窦先形成酷似人脑动静脉畸形团的、且两侧网状吻合的微血管网（ＲｅＭ），再汇聚成主要向颅内供血的颈内动脉。无发达颅内段的推动脉主要向颈髓供血。枕动脉可向上颈髓和后颅窝供血。咽升、椎和枕动脉三者间存在侧支吻合。锁骨下动脉有与人类相似的颈部分支。结论ＣＥＭＰ是脑与脊髓血管病研究和介入医师培训的良好模型。
To observe the head and neck vascular imaging of Chinese experimental miniature pig (CEMP) and to explore its application. Methods CEMP head and neck angiography, analysis of the image and compared with the human image. Results Pig without internal carotid artery extracranial segment, replaced by pharyngeal ascending artery, the latter in the cavernous sinus resembles the formation of human cerebral arteriovenous malformations, and the bilateral mesh anastomosis of the microvascular network (ReM), and then converged into the main Intracranial internal carotid artery. Inferred intracranial segment of the main artery to the cervical cord blood supply. The occipital artery supplies blood to the upper cervical and posterior fossa. Pharyngeal ascending, vertebral and occipital artery between the side branch anastomosis. The subclavian artery has a neck branch similar to humans. Conclusions CEMP is a good model for brain and spinal vascular disease research and interventional physician training.
