To describe and illustrate the prostatic arterial anatomy from human cadaveric specimens, highlighting implications for prostatic arterial embolization.
Dissection of 18 male pelves from white adults 35-68 years old was performed in the anatomy laboratory. Arterial branches were identified according to standard dissection technique using a 20-diopter magnifying lens for the prostatic sector. The branches were colored with red acrylic paint to enhance contrast and improve visualization.
Two main arterial pedicles to the prostate from each hemipelvis were identified in all cadaveric specimens: the superior and inferior prostatic pedicles. The superior prostatic pedicle provides the main arterial supply of the gland and provides branches to both the inferior bladder and the ejaculatory system. The inferior prostatic pedicle distributes as a plexus in the prostatic apex and anastomoses with the superior pedicle. This pattern of prostatic arterial distribution was constant in all cadaveric specimens. In contrast, the origin of the superior prostatic pedicle was variable from different sources of the internal iliac artery.
The description and illustration of the prostatic arterial anatomy, as demonstrated by this cadaveric study, may provide useful information and guidance for prostatic arterial embolization.
描述并展示来自人体尸体标本的前列腺动脉解剖结构，重点阐述其对前列腺动脉栓塞术的意义。
在解剖实验室对18具35至68岁白人成年男性骨盆进行解剖。使用20屈光度放大镜，依据标准解剖技术识别前列腺区域的动脉分支。用红色丙烯酸漆给分支上色以增强对比度并改善可视性。
在所有尸体标本中，均识别出每侧半骨盆至前列腺的两条主要动脉蒂：前列腺上蒂和前列腺下蒂。前列腺上蒂为腺体提供主要动脉血供，并为膀胱下部和射精系统提供分支。前列腺下蒂在前列腺尖部分布成丛，并与上蒂吻合。这种前列腺动脉分布模式在所有尸体标本中均恒定不变。相比之下，前列腺上蒂的起源在髂内动脉的不同来源处存在差异。
本尸体研究所示的前列腺动脉解剖结构的描述和展示，可能为前列腺动脉栓塞术提供有用的信息和指导。
