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 (CTA) is the gold standard for visualizing
pelvic arterial anatomy. In this study, morphometric analyses were performed
with CTA in 121 patients (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 (36%),
gluteopudendal trunk (7.4%), obturator (5,8%), inferior gluteal (3.3%), middle
rectal (0.8%), umbilical (0.8%) and inferior rectal (0.8%) arteries, and the
vesical trunk (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 (31%), obturator artery (13%), gluteopudendal trunk (9.1%),
vesical trunk (2.5%) and inferior gluteal artery (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.
