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﹤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﹥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﹤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。OBJECTIVE To observe the anatomy structure of phrenic nerve and vagus nerve and analyze the feasibility of car- diac function reconstruction by transposition of phrenic nerve to vagus nerve in the rat model. METHODS From January 2011 to January 2012, 40 cases of healthy male rats were selected as the research objects and were dissected to observe the phrenie nerve and vagus nerve under surgical microscope. We measured the diameter and the spacing of the phrenic nerve and vagus nerve. RESULTS In the initial plane of trunk, the bilateral trunk diameters of vagus nerve were 0.26±0.01 mm and 0.26± 0.01 mm, which were greater than phrenic nerve （0.22± 0.01 mm and 0.22 ±0.01 mm）, the difference were statistically sig- nificant （P 〈 0.05）. In the superelavical plane, the trunk diameters of bilateral vagus nerve were 0.26±0.02 mm and 0.26±0.01 mm, which had no obvious difference with phrenic nerve （0.25±0.01 mm and 0.26±0.01 mm）, and in the superclavi- cal plane, the spacing of the phrenie nerve and vagus nerve was minimum （1.84±0.24 mm and 1.82± 0.31 mm）, so the sur- gical anastomosis in this plane was most appropriate. In the cardiac plane, the trunk diameters of bilateral vagus nerve were 0.28± 0.02 mm and 0.28 ±0.01 mm, which had no obvious difference with phrenic nerve （0.27±0.02 mm and 0.27±0.01 mm）, but in the cardiac plane, the spacing of the phrenic nerve and vagus nerve was maximum, so the surgical anastomosis in this plane was not appropriate. CONCLUSION In the superelavical plane, the trunk diameter of bilateral phrenic nerve has no obvious difference with trunk diameter of vagus nerve, and the spacing of the phrenic nerve and vagus nerve is minimum, so the surgical anastomosis in this plane is most appropriate.
