Erectile dysfunction (ED) can affect your confidence, relationships, and quality of life. But ED doesn’t have just one cause, and understanding what’s contributing to it can help you find appropriate treatment.
Two vascular causes are venous leak and arteriogenic ED. One involves difficulty retaining blood in the penis; the other involves difficulty getting enough blood into it. Some men have both.
At Vein, Heart and Vascular Institute, Dr. Hesham Fakhri and our team evaluate vascular causes of ED and recommend care based on your symptoms, medical history, and test results.
During an erection, arteries deliver blood to the penis. The erectile tissue, called the corpora cavernosa, fills and expands, compressing the veins that normally drain blood away. This helps keep blood inside the penis and maintain firmness.
Venous leak ED, also called veno-occlusive dysfunction, occurs when this blood-retaining mechanism doesn’t work effectively. Blood drains away too quickly, making it difficult to achieve or maintain a firm erection.
Venous leak can occur even when arterial blood flow is adequate, but some men also have reduced arterial blood flow.
Changes in penile tissue, Peyronie’s disease, injury, and certain pelvic surgeries may contribute to problems with blood retention. Diabetes and other conditions that affect blood vessels and erectile tissue may also play a role.
Arteriogenic ED occurs when the arteries cannot deliver enough blood to the penis for a firm erection. Narrowed or damaged arteries can limit this blood flow.
Risk factors include smoking, diabetes, high blood pressure, high cholesterol, and obesity. Because these factors also affect the heart and other blood vessels, evaluating vascular ED offers an opportunity to review your cardiovascular health.
Reduced arterial blood flow may make it difficult to achieve a firm erection. Venous leak may make it difficult to maintain firmness.
However, these symptoms overlap. Men with either condition may have trouble both getting and maintaining an erection, and some have a combination of arterial and venous problems.
Difficulty maintaining an erection does not, by itself, confirm a venous leak. Hormonal conditions, medications, nerve problems, stress, and other factors can also contribute to ED.
An evaluation starts with a discussion of your symptoms, health history, medications, and previous treatments. A physical examination and appropriate blood tests may help identify contributing conditions, such as diabetes or low testosterone.
When a vascular cause is suspected, penile duplex ultrasound may help assess blood entering and leaving the penis. This test is typically performed after medication is administered to stimulate an erection and requires careful interpretation.
Additional imaging may be recommended for selected patients when planning a vascular procedure.
Treatment depends on the underlying cause, your overall health, your preferences, and your response to previous therapies.
Options may include:
For selected patients with confirmed venous leak, particularly when other treatments have not provided adequate improvement, venous embolization may be an option.
This minimally invasive procedure targets abnormal venous drainage pathways to help reduce blood outflow from the penis. Studies have reported improvements in erectile function in selected patients, although results vary and evidence on long-term durability continues to develop.
Your consultation includes a discussion of potential benefits, risks, alternatives, and the possibility of needing medication or additional treatment afterward.
For selected patients with a confirmed arterial blockage, a procedure to improve blood flow may be considered after a detailed vascular evaluation.
Angioplasty, stenting, or surgical revascularization is appropriate only in particular circumstances. The decision depends on the location and nature of the blockage, your overall health, and other findings—not simply the severity of your ED.
You don’t have to navigate ED on your own. Identifying its cause can help you understand your options and choose a treatment plan that fits your needs.
Contact Vein, Heart and Vascular Institute to schedule an evaluation in Tampa, Wesley Chapel, or Sun City Center, Florida. Dr. Fakhri and our team can help determine whether a vascular condition is contributing to your symptoms and discuss appropriate next steps.
