Erectile dysfunction (ED) is defined as the persistent inability to reach or maintain penile rigidity enough for sexual satisfaction. Nearly 30% of the men between ages 40 and 70 years are affected by ED. A variety of pathologies, including neurological, psychological, or endocrine disorders and drug side effects, may incite ED. A commonly identified cause of ED is vascular disease. Initial diagnostic workup includes a detailed physical examination and laboratory tests. Whilst duplex ultrasound is considered the first-line diagnostic modality, intra-arterial digital subtraction angiography is still considered the 'gold standard' for the diagnosis of arteriogenic impotence. Percutaneous endovascular treatment may be offered in patients with vasculogenic ED that has failed to respond to oral medical therapy as an alternative to penile prosthesis or open surgical repair. In arteriogenic ED balloon angioplasty of the aorto-iliac axis, and in veno-occlusive ED, percutaneous venous ablation using various embolization materials has been reported to be safe and to improve sexual performance. Recently, the ZEN study investigated the safety and feasibility of drug-eluting stents for the treatment of arteriogenic ED attributed to internal pudendal artery stenosis with promising preliminary results. This manuscript highlights the role of interventional radiology in the diagnosis and minimally invasive treatment of male impotence.
