Arterial Inflow Procedure for Erectile Dysfunction in Singapore
Minimally Invasive Treatment for Selected Erectile Dysfunction Caused by Arterial Insufficiency
An arterial inflow procedure is a minimally invasive endovascular treatment that aims to improve blood flow to the penis in selected men with arterial insufficiency contributing to erectile dysfunction (ED).
An erection depends on adequate blood flow into the erectile tissues of the penis. When an artery supplying the penis is significantly narrowed or blocked, reduced arterial inflow may contribute to difficulty achieving or maintaining an erection.
During an arterial inflow procedure, a thin catheter is guided through the blood vessels to assess the arteries supplying the penis. Where a suitable narrowing or blockage is identified, angioplasty and, in selected cases, stenting may be used to improve blood flow through the affected artery.
Arterial inflow treatment is not suitable for every man with erectile dysfunction. ED can have many different causes, including vascular, hormonal, neurological, medication-related and psychological factors. Careful assessment is therefore important to determine whether arterial insufficiency is contributing to the problem.
At the Supreme Vascular and Interventional Clinic, arterial inflow procedures are performed as part of a specialist vascular approach to selected cases of erectile dysfunction.

What Is an Arterial Inflow Procedure?
An arterial inflow procedure is a catheter-based treatment designed to improve blood flow through arteries supplying the penis.
For an erection to occur, the erectile tissues require increased arterial blood flow. If an artery supplying the penis has a significant narrowing or blockage, blood flow may be insufficient to support normal erectile function.
An arterial inflow procedure allows the specialist to examine the relevant blood vessels using angiography and, where an appropriate arterial lesion is identified, treat the narrowing using an endovascular technique.
Treatment may involve:
- Balloon angioplasty to widen a narrowed artery
- Stenting to help maintain the opening of a treated artery in selected cases
- Treatment of a selected abnormal arterial connection when clinically appropriate
The exact treatment depends on the location and characteristics of the arterial abnormality.
It is important to remember: Arterial inflow treatment is intended for selected patients in whom arterial insufficiency is identified as an important contributor to erectile dysfunction. It is not a general treatment for all forms of ED.
How Does Arterial Inflow Treatment Work?
Improving Blood Flow Through the Arteries Supplying the Penis
Before treatment, your specialist will assess your symptoms, medical history, vascular risk factors and previous ED treatments.
Additional testing may be used to determine whether arterial insufficiency is present and whether an arterial inflow procedure may be appropriate.
Depending on the clinical situation, assessment may include:
- Physical examination
- Medical and sexual health history
- Penile Doppler ultrasound
- Vascular imaging
- Angiography when an endovascular procedure is being considered
During the procedure, a thin catheter is introduced into an artery, commonly through the wrist or groin. The catheter is guided through the blood vessels towards the arteries supplying the penis.
Contrast dye and X-ray imaging are then used to visualise the blood vessels and identify areas of narrowing, blockage or other vascular abnormalities.
If a suitable arterial narrowing is identified, the specialist may perform balloon angioplasty to widen the affected artery. In selected cases, a stent may be placed to help keep the treated artery open.
Angioplasty/stenting specifically involves access using tiny 2 mm incision in the artery of the groin or wrist. Small tubes called catheters are advanced into the arteries all the way to check if there is any blockage in arterial flow to the penis. The blood flow is opened up as required using balloon dilatation or stenting of blocked arteries. Occasionally, there are arteriovenous connections called fistula seen on angiogram stealin arterial blood from the penis that can be treated at same time.
The catheter is removed after the planned treatment is completed, and the access site is monitored during recovery. The procedure has high success rate and is minimally invasive.


Who May Benefit From an Arterial Inflow Procedure?
Treatment Depends on the Cause of Erectile Dysfunction
Not all erectile dysfunction is caused by arterial insufficiency.
An arterial inflow procedure may be considered when assessment suggests that reduced arterial blood flow is a significant contributor to ED and a suitable vascular abnormality can be identified.
Your specialist may consider:
- Evidence of arterial insufficiency
- The location and severity of arterial narrowing
- The blood vessels supplying the penis
- Your age and overall health
- Cardiovascular risk factors
- Previous treatments for erectile dysfunction
- Whether the arterial disease is focal or more widespread
- Whether the potential benefits of intervention outweigh the risks
Arterial treatment is generally considered only after careful assessment because erectile dysfunction can result from multiple interacting causes.
Vascular Risk Factors and Erectile Dysfunction
Erectile dysfunction can sometimes be associated with underlying vascular disease.
Conditions and risk factors such as:
- Diabetes
- High blood pressure
- High cholesterol
- Smoking
- Obesity
- Atherosclerosis
- Cardiovascular disease
may affect blood vessel health and contribute to erectile difficulties.
For this reason, an assessment for ED may also provide an opportunity to identify broader cardiovascular risk factors.
Arterial Inflow Procedure vs Other Erectile Dysfunction Treatments
Understanding Your Treatment Options
Erectile dysfunction can be treated in several different ways depending on its underlying cause.
| Treatment Approach | How It Works |
|---|---|
| Medical Management | Addresses underlying health and vascular risk factors and may include medications for erectile dysfunction |
| Vacuum Erection Device | Uses negative pressure to draw blood into the penis and support an erection |
| Intracavernosal Injections | Uses medication injected into the erectile tissue to produce an erection |
| Arterial Inflow Procedure | Uses catheter-based techniques such as angioplasty, with stenting in selected cases, to improve blood flow through a suitable arterial narrowing |
| Endovascular Revascularisation | Uses minimally invasive catheter-based techniques to restore blood flow through a suitable arterial blockage or narrowing |
| Venous Leak Embolisation | Uses embolisation to block selected abnormal veins when abnormal venous outflow is identified as a contributing vascular problem |
| Penile Prosthesis | Surgically implants a device that provides a mechanical means of producing an erection |
The most appropriate treatment depends on the cause of ED, previous treatment response, overall health and individual preferences.
An arterial inflow procedure is not a replacement for standard ED treatment in every patient. It is a specialised option for carefully selected patients with a treatable arterial cause.
What Is Penile Arterial Insufficiency?
When Reduced Arterial Blood Flow Contributes to ED
Penile arterial insufficiency occurs when the arteries supplying the penis cannot provide adequate blood flow for normal erectile function.
This may occur because of:
- Atherosclerotic arterial disease
- Focal arterial narrowing
- Previous pelvic or perineal trauma
- Other vascular abnormalities
The arteries involved can include branches of the internal pudendal and penile arterial circulation.
However, erectile function is complex. Adequate arterial inflow is only one part of the process. This is why identifying a vascular abnormality does not automatically mean that an arterial procedure will improve erectile function.
Careful patient selection and assessment are important.
How Is Arterial Insufficiency Diagnosed?
Detailed Assessment Before Treatment
A specialist assessment is required before an arterial inflow procedure is considered.
Depending on your individual circumstances, investigations may include:
Penile Doppler Ultrasound
A penile Doppler ultrasound can assess blood flow within the penile arteries and provide information about arterial inflow and erectile haemodynamics.
Vascular Imaging
Additional vascular imaging may be used to assess the arteries supplying the penis and identify significant narrowing or other abnormalities.
Angiography
Angiography uses contrast dye and X-ray imaging to visualise the blood vessels.
When an endovascular treatment is being considered, angiography can provide detailed information about the arterial anatomy and help identify a potential target for treatment.
Not every patient requires every investigation. Your specialist will determine which tests are appropriate based on your symptoms and clinical assessment.
Potential Benefits of Arterial Inflow Treatment
Improving Blood Flow in Carefully Selected Patients
For appropriately selected patients with arterial insufficiency, an arterial inflow procedure may offer potential benefits.
Minimally Invasive
Treatment is performed through a catheter rather than open vascular surgery.
Directly Targets Arterial Disease
The procedure can address a specific narrowing or blockage in an artery supplying the penis.
May Improve Penile Blood Flow
Successful treatment of a suitable arterial lesion may improve blood flow to the erectile tissues.
May Provide an Alternative to More Invasive Treatment
Endovascular treatment may offer a less invasive approach than open vascular reconstruction for selected patients.
Can Be Combined With Broader ED Management
Treatment can form part of an overall erectile dysfunction management plan when other contributing factors are also addressed.
It is important to remember: Results vary between patients. The potential benefit depends on the underlying cause of ED, the arterial anatomy and whether a suitable vascular lesion can be successfully treated.
What Are the Potential Risks and Limitations?
Understanding the Risks
Arterial inflow procedures are specialised vascular interventions and carry potential risks.
Potential risks may include:
- Bleeding or bruising at the catheter access site
- Contrast-related reactions
- Stent-related complications where a stent is used
- Re-narrowing of the treated artery
- Need for further treatment
- Failure to improve erectile function
Importantly, treating an arterial narrowing does not guarantee improvement in erectile function. This is because ED can involve multiple factors, including arterial disease, impaired erectile tissue function, hormonal factors, medications, neurological conditions and psychological factors.
Your specialist will discuss the potential benefits, limitations, risks and alternative treatments before recommending an intervention.
Recovery After an Arterial Inflow Procedure
What Can You Expect After Treatment?
Because arterial inflow treatment is performed through a catheter, recovery is generally focused on monitoring the vascular access site and assessing your overall condition.
You may experience temporary:
- Bruising
- Mild discomfort
- Swelling around the catheter access site
Your specialist will provide personalised instructions regarding:
- Wound and access-site care
- Medication
- Physical activity
- When to return to normal activities
- When sexual activity can be resumed
- Follow-up appointments
- Assessment of erectile function
The timing of recovery varies according to the procedure performed and your individual circumstances. Most patients are discharged on the same day, although an overnight stay may be required if a stent was placed or if blood flow requires longer monitoring and return to light daily activities and desk work within 2 to 3 days following treatment. Full recovery typically takes 1 to 2 weeks.

Arterial Inflow Procedure and Venous Leak Treatment
Different Vascular Causes Require Different Treatments
Arterial insufficiency and venous outflow problems are different vascular mechanisms that may contribute to erectile dysfunction.
An arterial inflow procedure aims to improve blood entering the erectile tissues by treating a suitable arterial narrowing or blockage.
Venous leak embolisation, by contrast, is intended to address abnormal venous outflow in selected patients by blocking targeted veins.
These are different procedures and should not be considered interchangeable. The appropriate treatment depends on the underlying vascular abnormality identified during assessment.
