Images – Penile necrotic ulcer following prostatic artery embolization: A rare complication

摘要

Prostatic artery embolization (PAE) has been shown to be asafe and effective technique in treating patients with lowerurinary tract symptoms (LUTS) secondary to benign prostatichyperplasia (BPH).1 PAE is thought to work throughdegeneration and necrosis of prostatic cells, leading to fibrosisand decrease in overall prostate volume.2 While selectiveembolization is usually always performed, non-targetembolization may occur, as intravascular particles may refluxinto adjacent penile, vesical, or rectal arteries. Ischemia andulceration of these structures has been reported in most caseseries and trials, usually manifesting as self-limited lesionsand hematuria, hematospermia, or hematochezia.3 Seriouscomplications secondary to non-target embolization remainrare. We present here a rare case of focal penile necroticulceration secondary to non-target embolization during PAE.We provide clinical images of the lesion, as well as proceduralradiological images. We also review and discuss thecurrent literature on PAE and its potential complications.
