摘要
目的 观察大脑动脉环后交通动脉的形态变异。 方法 取 5 0例经福尔马林处理的台湾地区成年男性大脑 ,用光学摄像系统摄取后交通动脉影像 ,冲映成照片后 ,再经扫描仪存入计算机并放大至 2 0倍 ,用打印机映出影像后测量并统计外径值。 结果 左侧后交通动脉近颈内动脉端外径为 1 72± 0 77(0 7~ 4 3)mm ,右侧则为 1 6 9± 0 78(0 8~ 3 3)mm。左侧后交通动脉近大脑后动脉端外径为 1 5 9± 0 5 8(0 8~ 3 0 )mm ,右侧则为 1 5 9±0 6 8(0 5~ 3 2 )mm。 结论 台湾地区测量值与大陆地区测量值有差异 。
Objective\ The posterior communicating arteries (PCoA) are the most variable in the cerebral arterial circle of Willis. The figure of Chinese in Taiwan is required to be filled up in the category of Chinese stream. Methods\ In this study, the outer diameter of the PCoA was measured through an imaging computing system with enlargement up to twenty times for the collected fifty formalined adult human brains of Chinese in Taiwan. Results\ The external diameter of the internal carotid end of the PCoA averaged 1\^72±0\^77( ±s )(0\^7 4 3) mm in the left and 1\^69±0 78(0\^8 3\^3) mm in the right; 1\^59±0\^58(0\^8\|3\^0) mm in the left side of the posterior cerebral end and 1\^59±0\^68(0\^5\|3 2) mm in the right side of it. Conclusion\ These data display close to the white people values and are wider than that of Mainland Chinese. It is due to virtue in the usage of measurement.\;[
