We examined the correlation between the intrapelvic vessels, especially prostatic vessels, and the vertebral venous system in the male dog by radiography. Aorta abdominalis branches the right and left external iliac arteries at the 6th lumbar vertebra, and is divided into the right and left internal iliac arteries and arteria sacralis mediana at the 7th lumbar vertebra. Arteria urogenitalis arises from the internal iliac artery at the middle of articulatio iliosacralis, and is divided into arteria vesicalis caudalis cranially and arteria prostatica caudally. Arteria prostatica is divided in the prostatic capsule and distributed to the prostatic parenchyma in which arteries form the network. Vena prostatica is distributed to the prostatic parenchyma, forming the network and entered vena urogenitalis after joining vena vesicalis caudalis. Vena urogenitalis joins the internal iliac vein, and then the common iliac vein and vena cava posterior after joining the external iliac vein. The anastomosis between the intrapelvic vein and the vertebral venous system is formed by the vena intervertebralis. The vertebral venous system is anastomosis with the vena cava posterior, the common iliac vein, the internal iliac vein and vena pudenda interna.
我们通过放射成像检查了雄性犬盆腔内血管，尤其是前列腺血管与椎静脉系统之间的相关性。腹主动脉在第6腰椎处分支为左右髂外动脉，并在第7腰椎处分为左右髂内动脉和骶中动脉。生殖动脉在髂骶关节中部起自髂内动脉，在头侧分为膀胱尾侧动脉，在尾侧分为前列腺动脉。前列腺动脉在前列腺囊内分支并分布于前列腺实质，动脉在其中形成网络。前列腺静脉分布于前列腺实质，形成网络，在与膀胱尾侧静脉汇合后汇入生殖静脉。生殖静脉汇入髂内静脉，然后在汇入髂外静脉后汇入髂总静脉和后腔静脉。盆腔内静脉与椎静脉系统之间的吻合由椎间静脉形成。椎静脉系统与后腔静脉、髂总静脉、髂内静脉和阴部内静脉吻合。
