Abstract
Background Prostate artery embolization (PAE) is a new embolization therapy to treat benign
prostate syndrome (BPS).
Materials and Methods This review article presents the rationale and impact mechanism of PAE, criteria
for patient selection, and discusses the anatomy of prostate arteries. The study results
are seen in the context of complications and clinical partners.
Results Important preconditions for successful prostate artery embolization are a strict
indication, precise knowledge of the anatomy of the pelvic arteries and advanced interventional-radiological
skills. Several studies showed that urological parameters after prostate artery embolization
improve at a similar level as for established post-surgical treatments. At the same
time, it could be proven that prostate artery embolization has no impact on erectile
function and is associated with a relatively low complication rate.
Conclusion PAE is increasingly developing to an alternative for the established surgical treatments
in BPS patients.
Key Points
-
PAE is a new embolization method for treating BPS and represents an alternative to
classic urological surgical procedure such as TURP.
-
Due to the low caliber of the prostate artery (0.5 – 2 mm), the presence of anatomical
variations, and the arteriosclerosis seen in most older men, PAE is a technically
challenging embolization method.
-
In patients with a high postoperative bleeding risk in classic urological surgical
treatment concepts, PAE is a very gentle alternative method.
