Interventional embolization for treatment of benign prostatic hyperplasia patients with common trunk of prostate artery and dorsal penile artery / 中国介入影像与治疗学

ABSTRACT

Objective: To observe the effect of interventional embolization in treatment of benign prostatic hyperplasia (BPH) patients with common trunk of prostatic artery (PA) and dorsal penile artery. Methods: Data of 29 BPH patients with common trunk of PA and dorsal penis artery treated with interventional embolization were retrospectively analyzed. Results: Among 29 patients, superselective embolization of PA with small PVA particles (diameter 150-300 μm) was successfully performed in 12 cases. Postembolization angiography showed that the prostatic parenchyma staining disappeared, while the dorsal penis artery existed. Clinical symptoms were significantly improved in these 12 patients, and no penis-related complications occurred. However, microcatheter could not enter into PA in the rest 17 cases, among them conventional embolization with small PVA particles was performed in 2 cases, the symptoms such as dysuria were significantly improved after operation, but penile ischemia and necrosis occurred. Embolization with large PVA particles (350-560 μm in diameter) was performed in 3 cases, no complication of penile occurred after operation, but the improvement of symptoms was limited. The other 12 cases were embolized with small PVA particles after temporary ligation on the root of penis with rubber strips, the symptoms were obviously improved after operation, and no complication of penis ischemia nor necrosis occurred. Conclusion: Interventional embolization is effective for BPH patients with common trunk of prostate artery and dorsal penis artery. The details of embolization should be individually adjusted according to vascular anatomy and the possibility of superselection.
