摘　　要：目的研究男性标本脐动脉的解剖学特点,为临床膀胱癌切除术中结扎脐动脉提供理论依据。方法随机选用福尔马林液固定的成年男性尸体19具(38侧),解剖观测脐动脉的起点、走行、起始端外径及分支,结果进行统计学分析。结果脐动脉均起自髂内动脉。脐动脉起始端外径为(3.02±0.30)mm。脐动脉均发出膀胱上动脉,其分支有5种类型:数支膀胱上动脉型,占总标本量的52.6%(20侧);数支膀胱上动脉和1支膀胱下动脉型,占28.9%(11侧);2支膀胱上动脉、1支膀胱下动脉与闭孔动脉的共干动脉型,占5.3%(2侧);数支膀胱上动脉和1支闭孔动脉型,占7.9%(3侧);2支膀胱上动脉和1支精囊动脉型,占5.3%(2侧)。结论脐动脉起始位置固定,起始端外径狭小,分支数目变异较多,对膀胱手术有重要意义。Objective To study the anatomical characteristics of umbilical artery in male specimens,so as to provide theoretical support for ligation of umbilical artery in clinical bladder cancer resection.Methods Nineteen adult male cadavers(38 sides)fixed by formalin were collected randomly.The starting point,course,external diameter and branches of the umbilical artery were observed and analyzed.Results The umbilical artery originated from the internal iliac artery.The outer diameter of umbilical artery was(3.02±0.30)mm.We found there were five branch types of the umbilical artery.Ⅰ.several superior vesical arteries,accounting for 52.6%(20 sides).Ⅱ.several superior vesical arteries and one inferior vesical artery,accounting for 28.9%(11 sides).Ⅲ.two superior bladder arteries and one common trunk vessel of the inferior bladder artery and the obturator artery,accounting for 5.3%(2 sides).Ⅳ.several superior vesical arteries and one obturator artery,accounting for 7.9%(3 sides).Ⅴ.two superior vesical arteries and one seminal vesicle artery,accounting for 5.3%(2 sides).Conclusions The starting site of the umbilical artery is fixed,the diameter of the starting end is narrow and the number of branches is varied.
