85 year-old male with Benign Prostatic Hyperplasia, severe lower urinary tract symptoms (IPSS 29), and 110 g prostate, who comes to interventional radiology for prostatic artery embolization. Left internal iliac angiography demonstrates common trunk of the superior and inferior vesical arteries (a). The left prostatic artery (PA) was selected with the SwiftNINJA® steerable microcatheter, with time to target vessel selection (microcatheter moved from tip of 5F catheter to successful left PA cannulation) of 12 s. No guidewire was needed. Left PA DSA demonstrates tortuous PA branches with no extra-prostatic enhancement (b). After initial relatively proximal left PA embolization, the steerability of the microcatheter was used to navigate through a tortuous 360-degree loop to gain more distal access (c), without the need for a guidewire. Additional distal embolization was then performed, following the “PErFecTED” technique. Patient was discharged home the same day. IPSS decreased to 8 within 1 month post procedure. Total procedure time for bilateral PAE was 100 min
