Venogenic erectile dysfunction: diagnosis on computed tomography cavernosography and endovascular treatment using an anterograde access via deep dorsal penile vein.

BACKGROUND

The underlying etiologies of erectile dysfunction may be manifold. Among them, vasculogenic etiologies are of increasing relevance and are not strictly limited to the elderly population. According to recent study, venogenic erectile dysfunction appears to be even more relevant than arteriogenic erectile dysfunction. Venogenic erectile dysfunction due to venous leakage causes insufficient penile blood retention. Proper diagnosis of venous leakage should include both color Doppler flow analysis and computed tomography cavernosography for adequate patient selection and treatment planning. Besides surgical ligation of penile draining veins, endovascular treatment methods may demonstrate more promising results. Especially endovascular embolization of venous leakage using an anterograde access via deep dorsal penile veins appears to be more beneficial for patients' clinical outcome and awareness of this technique should be raised among endovascular interventionalists.

CASE PRESENTATION

A 47-year-old man was diagnosed with venogenic erectile dysfunction due to venous leakage on color Doppler flow analysis and computed tomography cavernosography. He did not respond to PDE-5-inhibitors. This patient demonstrated major venous leakage of paired deep dorsal penile veins via periprostatic veins and internal pudendal veins draining into both iliohypogastric veins. This patient's venous leak was treated with endovascular embolization using an anterograde access via deep dorsal penile veins.

CONCLUSION

This patient's erectile dysfunction due to venous leakage, based on findings in color Doppler flow analysis and computed tomography cavernosography, was embolized using an anterograde access via deep dorsal penile veins as a minimally-invasive endovascular treatment option.
