【摘要】：目的观察大鼠膈神经和迷走神经的解剖结构并分析膈神经移位迷走神经支配心脏的可行性。方法于2011年1月～2012年1月选取40只健康雄性大鼠为研究对象,在手术显微镜下解剖观察大鼠的膈神经和迷走神经,并测量其直径和二者的间距。结果在主干起始平面,大鼠左右迷走神经主干直径分别为(0.26±0.01)mm和(0.26±0.01)mm,均大于膈神经(0.22±0.01)mm和(0.22±0.01)mm,比较差异有统计学意义(P㩳0.05)。在锁骨上平面,大鼠左右迷走神经主干直径分别为(0.26±0.02)mm和(0.26±0.01)mm,与膈神经直径(0.25±0.01)mm和(0.26±0.01)mm)比较无明显差别(P㧐0.05),并且在锁骨上平面,左右侧膈神经与迷走神经的距离均是最小的,分别为(1.84±0.24)mm和(1.82±0.31)mm,所以在此平面进行吻合是最合适的。在心脏平面,大鼠左右迷走神经主干直径(0.28±0.02)mm和(0.28±0.01)mm)与膈神经直径(0.27±0.02)mm和(0.27±0.01)mm比较无明显差别(P㩳0.05),但此平面膈神经与迷走神经的距离较大,不适合进行吻合操作。结论大鼠膈神经在锁骨上平面直径与迷走神经差别不大,且二者相对间距最小,可以直接进行缝合,实现膈神经移位迷走神经支配心脏。
[Abstract]:Objective to observe the anatomical structure of phrenic nerve and vagus nerve in rats and to analyze the feasibility of phrenic nerve transposition into vagus nerve.Methods from January 2011 to January 2012, 40 healthy male rats were selected as subjects. The phrenic and vagus nerves of the rats were dissected under a surgical microscope, and their diameters and distances between them were measured.Results the diameter of the vagus nerve trunk was 0.26 卤0.01)mm and 0.26 卤0.01mm in the starting plane of the trunk, which was larger than that of the phrenic nerve, 0.22 卤0.01)mm and 0.22 卤0.01mm. the difference was statistically significant.In the supraclavicular plane, the diameter of the left and right vagus nerve trunk in rats was 0.26 卤0.02)mm and 0.26 卤0.01mm, respectively, and there was no significant difference in the diameter of phrenic nerve (0.25 卤0.01)mm and 0.26 卤0.01mm). The distance between left and right phrenic nerve and vagus nerve was the smallest in the supraclavicular plane, and the distance between left and right phrenic nerve and vagus nerve was the smallest.They were 1.84 卤0.24)mm and 1.82 卤0.31 mm, respectively.There was no significant difference in the diameter of left and right vagus nerve trunk (0.28 卤0.02)mm and 0.28 卤0.01mm) from phrenic nerve (0.27 卤0.02)mm) and phrenic nerve (0.27 卤0.01)mm) in cardiac level. However, the distance between phrenic nerve and vagus nerve in this plane was relatively large, so it was not suitable for anastomosis.Conclusion the diameters of phrenic nerve in the supraclavicular plane are not different from that of vagus nerve, and the relative distance between them is the smallest, so the phrenic nerve can be directly sutured and transferred to the vagus nerve to innervate the heart.
