前列腺表面动脉的应用解剖研究

Applied Anatomy of the Arteries on the Prostatic Surface

本文用苏州地区成人尸体34例(68侧),在手术显微镜下观测.前列腺表面的动脉每侧8.01±0.27支,其中分布在前、后包膜和后结合部为最多,其外径以后包膜、侧包膜部分支最大.前列腺前、后包膜表面分别可见一小动脉吻合网,前动脉网以星型多见,后动脉网呈倒三角形.本组中副阴部动脉的出现率较高,且均沿前包膜走行。本文还探讨了前列腺表面动脉的意义。

In this paper,68 cases of cadaver were observed under the operation microscope.It shows that the majority of branches distribute to the anterior posterior capsule and poste- rior prostatovesicular junction,but the external diameter of the arterioles are bigger on the posterior and lateral ones.On the anterior and posterior of capsule of the gland,there is an arteriolar net.The patteren of the anterior net is starlike and that of posterior one is reversive trianglelike.The accessory pudendal artery was frequently.All of the arteries pass along the anterior surface of the capsule.The significance of the arteries the prostatic sur- face is discussed as well,
