    Purpose: To evaluate safety and effectiveness of prostatic artery embolization (PAE) using polyethylene glycol (PEG) microspheres in patients with moderate-to-severe benign prostatic hyperplasia (BPH).Materials and methods: A single-center, prospective study of 30 patients who underwent PAE from August 2020 to December 2021 using PEG 400-mu m microspheres was conducted. Patient evaluation data using International Prostate Symptom Score (IPSS), quality of life (QoL) score, prostate-specific antigen (PSA), peak urinary flow rate (Qmax), postvoid residual volume (PVR), and prostate volume (PV) at baseline and 3 and 12 months after PAE were obtained.Results: Bilateral PAE was performed in all patients. One patient had early clinical failure (3.3%) and another presented with lower urinary tract symptoms (LUTSs) recurrence (3.3%) at the 12-month follow-up. Twenty-eight patients (93.3%) experienced significant and durable LUTS improvement. Mean absolute (and relative) improvement at 3 and 12 months were: IPSS, 14.6 points (-69%) for both; QoL, 3.3 points (-70%) and 3.5 points (-74%); Qmax, 6.3 mL/s (+78%) and 8.6 mL/s (+100%); PSA reduction, 1.2 ng/mL (-22%) and 1.0 ng/mL (-15%); PVR reduction, 48 mL (-56%) and 58.2 mL (-49%); PV reduction, 23.4 cm(3) (-29%) and 19.6cm(3) (-25%); (P < .05 for all). No major adverse events were observed. Minor adverse events included urinary tract infection (4/30, 13.3%), prostatic tissue elimination (3/30, 10%), penile punctiform ulcer (1/30, 3.3%), and urinary retention (1/30, 3.3%).Conclusions: PAE using PEG microspheres was observed to be effective with sustained LUTS improvement at the 12-month follow-up. The incidence of urinary infection and prostatic tissue elimination was higher than previously reported for other embolics.

    Advanced image guidance for prostatic artery embolization - a multicenter technical note
    (2021) CARNEVALE, Francisco Cesar; MCCLURE, Timothy; CADOUR, Farah; VIDAL, Vincent; ASSIS, Andre Moreira de; MOREIRA, Airton Mota; ROCHA, Arthur Diego Dias; REBET, Aya; NUTTING, Charles
    Background Prostatic artery embolization (PAE) is associated with patients' quality of life improvements and limited side effects compared to surgery. However, this procedure remains technically challenging due to complex vasculature, anatomical variations and small arteries, inducing long procedure times and high radiation exposure levels both to patients and medical staff. Moreover, the risk of non-target embolization can lead to relevant complications. In this context, advanced imaging can constitute a solid ally to address these challenges and deliver good clinical outcomes at acceptable radiation levels. Main text This technical note aims to share the consolidated experience of four institutions detailing their optimized workflow using advanced image guidance, discussing variants, and sharing their best practices to reach a consensus standardized imaging workflow for PAE procedure, as well as pre and post-operative imaging. Conclusions This technical note puts forth a consensus optimized imaging workflow and best practices, with the hope of helping drive adoption of the procedure, deliver good clinical outcomes, and minimize radiation dose levels and contrast media injections while making PAE procedures shorter and safer.
