简要总结

Venous leakage is one of the causes of erectile dysfunction and can be managed using different treatment modalities, including surgical ligation and percutaneous embolization. This randomized clinical trial aims to evaluate and compare the efficacy, durability, safety, side effects, and complications of two treatment procedures-embolosclerotherapy of the periprostatic plexus and deep dorsal vein revascularization-in the management of erectile dysfunction caused by venous leak.

详细描述

Venous leak embolization performed following an intracavernosal injection of 20 µg alprostadil with the patient positioned supine. After spinal anesthesia, a deep dorsal penile vein punctured under ultrasound guidance using a stiff 20-G micropuncture set, a 0.018-inch guidewire, and a 4-French introducer.

The introducer advanced through Buck's fascia into the deep dorsal vein, carefully positioned near the radix penis, and a diagnostic venogram obtained to confirm the presence of venous leakage.

All instruments then flushed with 0.9% saline solution. Venous embolization carried out using a slow, controlled injection of a liquid embolic agent, either ethylene-vinyl alcohol copolymer (EVOH) in DMSO with tantalum powder or a polidocanol and gel foam mixture, under continuous fluoroscopic monitoring.

The injection stopped in time to prevent unintended spread of the embolic material to the internal pudendal or periprostatic veins leading to the iliohypogastric veins, the external pudendal veins leading to the femoral veins, or the dorsal penile veins.

Penile venous arterialization performed by creating an end-to-end anastomosis between the inferior epigastric artery and the deep dorsal penile vein. The procedure begin with an infrapubic incision, through which the superficial penile veins ligated. Buck's fascia then incised and opened along the midline. A sufficient segment of the dorsal penile vein carefully dissected, and all emissary and circumflex veins in the area ligated.
