This work is aimed to describe anatomical features and variants of the prostatic artery (PA) using digital subtraction angiography (DSA).
This is a descriptive statistic study. We reviewed the DSA of 348 patients, who had a PA embolisation to reduce the benign prostatic hyperplasia (BPH) symptoms at Radiology Department of Bach Mai Hospital from Oct - 2014 to Oct - 2018.
PA was found at 660 pelvic halves, of which 30 pelvic halves (4.5%) had two PAs, 630 pelvic halves had one PA. In terms of the origin of PA, in total 690 PAs, the percentage of type 1, 2, 3, 4 and 5 was successively 33.9%, 13.9%, 18.3%, 23.9% and 10.4%, respectively. Atherosclerosis of PA observed in 20.9%. The 'corkscrew' pattern was found in 30.4%. The average diameter of PA was 1.5 ± 0.34mm. The anastomosis of PA with surrounding arteries was common. PA may supply rectum (6.1%), seminal vesical (9.6%), bladder (5.2%), contralateral prostatic parenchyma (13.0%), surrounding soft-tissues (3.5%).
The common trunk with SVA superior vesical artery was the most common origin of PA. Anastomoses of PA with surrounding tissues were complex.
本研究旨在利用数字减影血管造影（DSA）描述前列腺动脉（PA）的解剖特征及变异情况。
这是一项描述性统计研究。我们回顾了2014年10月至2018年10月在白梅医院放射科因良性前列腺增生（BPH）症状接受PA栓塞治疗的348例患者的DSA资料。
在660侧骨盆中发现了PA，其中30侧骨盆（4.5%）有两条PA，630侧骨盆有一条PA。就PA的起源而言，在总共690条PA中，1型、2型、3型、4型和5型的比例依次为33.9%、13.9%、18.3%、23.9%和10.4%。观察到PA的动脉粥样硬化发生率为20.9%。发现“螺旋状”模式的发生率为30.4%。PA的平均直径为1.5±0.34mm。PA与周围动脉的吻合很常见。PA可能供应直肠（6.1%）、精囊（9.6%）、膀胱（5.2%）、对侧前列腺实质（13.0%）、周围软组织（3.5%）。
与膀胱上动脉（SVA）共干是PA最常见的起源。PA与周围组织的吻合复杂。
