Anatomical Variation of the Prostate Artery in Computed Tomography Angiogram

Background: Understanding the prostate artery anatomy is the cornerstone in successful planning of prostatic artery embolization for benign prostatic hyperplasia. The purpose of our pager is to understand the variable normal Prostate Artery anatomy using computed tomogrpahy (CT) angiogram of our population. Methods: We retrospectively evaluated 100 internal iliac arteries' (IIA) thin collimated CT angiogram images, and three-dimensional reformats of 50 healthy kidney donor candidate, aged between 17 and 47 years old (median 27). In each IIA, we identified the origin of the prostate artery, obturator artery, superior vesical artery, and the middle rectal artery. Results: The prostate artery is seen in 97% of the examined IIAs. It most commonly originates from the common trunk of the internal pudendal artery (IPA) and inferior gluteal artery (IGA) (48%), followed by a direct origin from the IPA (43%). In only 4% of the PA seen originating from the obturator artery (OA) and 2% from other origins. Conclusion: CT angiogram is considered a helpful tool in understanding the different anatomic variations of the prostate artery. The common trunk of the IPA and IGA is the most common origin of the prostate artery, followed by the IPA. OA, superior vesical artery, or the main internal iliac artery form an uncommon variant origins.
