Embolization of the deep dorsal vein for the treatment of erectile impotence due to veno-occlusive dysfunction

PURPOSE: We evaluate the effectiveness of deep dorsal vein embolization for the treatment of venous impotence. MATERIALS AND METHODS: A total of 32 impotent patients with veno-occlusive dysfunction underwent deep dorsal vein embolization. The condition was suspected based on findings of penile Doppler ultrasonography and cavernosometry. The diagnosis was confirmed with pharmacocavernosography that appeared to delineate venous leakage. During the procedure we isolated and cannulated the deep dorsal vein through a small dorsal penile incision with the patient under local anesthesia. We used a mixture of the tissue glue, N-butyl cyanoacrylate, and lipodol for embolization, with a total volume of 5 ml. injected antegrade into the previously catheterized dorsal vein under fluoroscopic control. As soon as we observed the occluded veins we performed repeat pharmacocavernosography. At 3-month followup patients were reassessed with history and cavernosometry. Followup ranged from 12 to 36 months (median 25). RESULTS: Of 32 patients 22 (68.7%) regained sexual activity, which was confirmed by cavernosometry. The remaining 10 patients (31.3%) experienced little if any clinical response, which correlated with cavernosometry. There were no significant side effects. CONCLUSIONS: Deep dorsal vein embolization for venogenic impotence is simple, effective and safe, and appears to be cost-effective. The results obtained in this limited number of patients are promising and justify trials in larger groups.
