1、临床医学论文•前列腺动脉的解剖观测及临床应用作者：李光忠，张木斯，杨月如［摘要］FI的研究成人前列腺动脉的來源、行程、进入前列腺的部位及其与神经丛的关系，为前列腺手术提供解剖学基础。方法在解剖显微镜下对30侧常规防腐固定的35〜60岁成年男性尸体前列腺动脉及神经丛作解剖、观测。结果30侧均有恒定的前列腺动脉，共有125支，来源丰富，主要来自膀胱下动脉(92.125,73.6%)，行程较恒定,在距膀胱前列腺间沟(22±8)mm处呈丫爪状分支，多数分支在膀胱前列腺间沟内进入前列腺底，按时钟顺序，各点钟处均有动脉进入，以3〜5或7〜9点居多
2、(87.125,69.6%)。前列腺神经丛由膀胱神经丛延续而来，在接近膀胱前列腺间沟处与前列腺动、静脉相互交织成网,进入前列腺包膜中。结论在距膀胱前列腺间沟20〜30mm处，环周结扎前列腺动脉，止血更为彻底，也可避免损伤神经从。［关键词］前列腺;前列腺动脉;神经丛;应用解剖AnatomicalobservationandclinicalapplicationoftheprostaticarteryAbstract:ObjectiveTostudytheorigin,course,anddistributionoftheprostati

8、此有所研究[1],但对该动脉的起源、行程有不同看法，对该动脉与周围器官及神经丛的关系报道很少。关于该动脉结扎的临床应用问题，国内外虽有报道[2・3],但尚缺乏充分的形态学依据。因此，本研究借助解剖显微镜对成人询列腺动脉的
