犬颈总动脉实验性虹吸段血管模型的建立

目的 探讨截取一侧颈总动脉节段与另一侧颈总动脉端端吻合建立颅底段颈内动脉（虹吸段）血管模型的可行性.方法 对8只成年家犬应用显微外科技术,将玻璃管制成“S”形,一侧颈总动脉（CCA）作为母体动脉,截取另一侧颈总动脉节段穿过玻璃管模型与对侧CCA端端吻合.2周后作血管造影（CTA/DSA）证实模型内血流通畅.结果 8只犬均成功地建成颅底段颈内动脉（虹吸段）血管模型.结论 应用犬一侧颈总动脉节段与另一侧颈总动脉端端吻合建立颅底段颈内动脉（虹吸段）血管模型切实可行.

Establishing experimental model of human internal carotid artery siphon segment in canine common carotid artery

Objective To study the feasibility of establishing experimental model of human internal carotid artery siphon segment in canine common carotid artery(CCA) by end-to-end anastomoses of one side common carotid artery segment with the other side common carotid artery.Methods Surgical techniques were used to make siphon model in 8 canines. One side CCA was taken as the parent artery and anastomosing with the cut off contra-leteral CCA segment which has passed through within the S-shaped glass tube.Two weeks after the creation of models angiography showed the model siphons were patent. Results Experimental models of human internal carotid artery siphon segment were successfully made in all 8 dogs.Conclusions It is practically feasible to establish experimental canine commoncarotid artery models of siphon segment simulating human internal carotid artery.
