Summary

Prostatic artery embolization (PAE) offers a minimally invasive solution for benign prostatic hyperplasia (BPH) symptoms by reducing prostate volume. Understanding prostatic arterial anatomy and utilizing advanced imaging are key to safe and effective PAE procedures.

Area of Science:

  • Interventional Radiology
  • Vascular Anatomy
  • Urology

Background:

  • Benign prostatic hyperplasia (BPH) causes lower urinary tract symptoms and urinary retention.
  • Prostatic artery embolization (PAE) is a minimally invasive treatment for BPH.
  • PAE induces ischemic necrosis, reduces prostatic volume, and decreases neuromuscular tone, addressing BPH's static and dynamic components.

Purpose of the Study:

  • To review prostatic arterial anatomy.
  • To explore advanced imaging's role in PAE.
  • To optimize procedural safety and efficacy through anatomical understanding and imaging guidance.

Main Methods:

  • Review of prostatic arterial anatomy.
  • Discussion of advanced imaging techniques for preprocedural planning and intraprocedural guidance.
  • Emphasis on precise identification of prostatic arteries and anastomoses.

Main Results:

  • PAE's dual mechanism effectively treats BPH symptoms.
  • Technical challenges of PAE require detailed vascular anatomical knowledge.
  • Minimizing nontarget embolization is crucial for safety.

Conclusions:

  • Accurate knowledge of prostatic arterial anatomy is essential for successful PAE.
  • Advanced imaging enhances procedural safety and efficacy.
  • PAE is a viable option for BPH management when performed with meticulous anatomical consideration.
