Abstract :Objectives: Radiological anatomy of the prostatic artery is important for any kind of surgical or interventional procedure related to the prostatic region. The aim of this study was to define prostatic arterial anatomy that is critical for both urologists dealing with prostatic interventions and interventional radiologists dealing with prostatic arterial embolization. Methods: Computed tomography angiography insert ignore into journalissuearticles values(CTA); is the gold standard for visualizing pelvic arterial anatomy. In this study, morphometric analyses were performed with CTA in 121 patients insert ignore into journalissuearticles values(41–89 years); retrospectively. The diameters and origins of 242 prostatic arteries were evaluated. Results: Average diameter of the right prostatic artery was 0.9–2.4 mm; in 39% of the patients the artery originated from the inferior vesical artery. The other origin patterns on the right side were the internal pudendal artery insert ignore into journalissuearticles values(36%);, gluteopudendal trunk insert ignore into journalissuearticles values(7.4%);, obturator insert ignore into journalissuearticles values(5,8%);, inferior gluteal insert ignore into journalissuearticles values(3.3%);, middle rectal insert ignore into journalissuearticles values(0.8%);, umbilical insert ignore into journalissuearticles values(0.8%); and inferior rectal insert ignore into journalissuearticles values(0.8%); arteries, and the vesical trunk insert ignore into journalissuearticles values(0.8%);. Average diameter of the left prostatic artery was 0.9–2.7 mm; in 36% of the patients the artery originated from the inferior vesical artery. Other origin patterns revealed for the left side were the internal pudendal artery insert ignore into journalissuearticles values(31%);, obturator artery insert ignore into journalissuearticles values(13%);, gluteopudendal trunk insert ignore into journalissuearticles values(9.1%);, vesical trunk insert ignore into journalissuearticles values(2.5%); and inferior gluteal artery insert ignore into journalissuearticles values(2.5%);. Conclusion: CTA is crucial for better understanding of the prostatic arterial anatomy and preventing the complications in surgical or interventional procedures such as prostatic arterial embolization, especially for atherosclerotic patients. The data obtained in this study is significant for determination of pelvic vascular disorders.
