摘　　要：目的明确大鼠尾动脉的解剖学特点,为显微吻合提供解剖学依据。方法采用经心脏插管天然橡胶灌注方法对10只大鼠行动脉灌注后解剖、10只大鼠行动静脉同时灌注后解剖,10只活体大鼠麻醉后直接解剖,观察大鼠尾动脉情况并测量尾动脉不同平面的外径。结果大鼠尾部腹侧正中有一条尾中动脉,并有一条尾中静脉与之伴行,动脉位于静脉浅层,尾中动脉节段性发出分支。尾中动脉于第5、第13、第23尾椎外径分别为(1.02±0.06)mm、(0.50±0.01)mm、(0.45±0.02)mm。尾中静脉于第5、第13、第23尾椎处外径分别为(1.60±0.09)mm、(0.89±0.03)mm(、0.71±0.04)mm。结论大鼠尾中动脉直径和显微外科手术中所需吻合的血管管径相似,此结果可指导大鼠尾动脉显微吻合及其相关研究。Objective To identify the anatomic characters of the caudal artery in rats so as to provide anatomical evidences for animal experiments. Methods Ten rats were subjected to anatomy following caoutchouc perfusion into the artery by inserting tubes through the heart, 10 were subjected to dissection following artery and vein perfusion, and 10 were subjected to dissection immediately following anesthesia. Diameter of the caudal artery was measured. Results In the ventral median of rat＇s caudae there was a coccygeal median artery erupting several branches. The coccygeal median vein accompanied it in deep layer. Transverse diameters of the coccygeal median artery and vein were 1.02 ± 0.06 mm, 1.60 ± 0.09mm at the fifth coccygeal vertebrae,0.50 ± 0.01 mm, 0.89 ± 0.03 mm at the thirteenth coccygeal vertebrae, and 0.45 ± 0.02 mm, 0. 71 ± 0.04 mm at the twenty-third coccygeal vertebrae. Conclusion The diameter of the coccygeal media artery in rat＇s caudae matches the requirement of anastomosis in mierosurgery.
