If you’ve been diagnosed with a varicocele, you may have questions about what it means, whether it needs treatment, and what your options are. For some men, a varicocele causes little or no noticeable discomfort. For others, it can lead to a dull, aching sensation in the scrotum, a feeling of heaviness, or concerns about fertility.
And while surgery is one established treatment option, it is not the only approach.
Varicocele embolization is a minimally invasive, nonsurgical treatment that can treat the abnormal veins responsible for a varicocele without an incision in the scrotum. The procedure is performed by an interventional radiologist using image guidance to block blood flow through the affected veins and redirect it through healthier veins.
At Conrad Pearson Clinic in Memphis, our team is committed to helping men understand their treatment options and find an approach that fits their individual needs.
What Is a Varicocele?
A varicocele is an enlargement of the veins within the scrotum. It is similar in some ways to varicose veins that develop in the legs.
Normally, veins contain one-way valves that help blood flow in the proper direction toward the heart. When those valves do not function properly, blood can flow backward and pool in the veins around the testicle. Over time, this increased pressure can cause the veins to become enlarged and more prominent.
Varicoceles are relatively common and often develop during adolescence or early adulthood. Some men never experience symptoms and may not even know they have one. Others may notice changes or discomfort that become more noticeable throughout the day.
Common symptoms can include:
- A dull or aching pain in the scrotum
- A feeling of heaviness or dragging
- Discomfort that becomes worse after standing or physical activity
- Symptoms that are more noticeable at the end of the day
- Relief when lying down
- Enlarged or twisted-looking veins in the scrotum
- Changes in testicular size or development
- Fertility concerns or changes in sperm quality
Because varicoceles can affect men differently, an evaluation is important before deciding whether treatment is necessary.
When Does a Varicocele Need Treatment?
Not every varicocele requires treatment. If a varicocele is not causing symptoms or affecting testicular health or fertility, your doctor may recommend monitoring it rather than treating it immediately.
Treatment may be considered when a varicocele is associated with persistent pain, testicular changes, or infertility.
For men who are trying to start or grow their families, a varicocele can be particularly concerning. Varicoceles have been associated with impaired semen parameters in some men, and treating a clinically significant varicocele may improve semen quality in appropriate patients.
A comprehensive evaluation can help determine whether the varicocele is likely contributing to your symptoms or fertility concerns and whether treatment could be beneficial.
What Is Varicocele Embolization?
Varicocele embolization is a minimally invasive alternative to surgical varicocele repair.
Instead of making an incision to access and repair the abnormal veins, an interventional radiologist reaches the affected veins from inside the blood vessel.
During the procedure, a small needle puncture is typically made in a vein in the upper thigh or groin area. A thin, flexible catheter is then guided through the veins toward the vessels responsible for the varicocele.
Using real-time X-ray imaging, known as fluoroscopy, the interventional radiologist can see the blood vessels and identify abnormal blood flow. Contrast material may be injected to help map the veins and confirm the location of the varicocele.
Once the affected vein is identified, the physician places an embolic material—such as a small coil or other medical agent—to block blood flow through the problematic vein.
The blood is then redirected through other healthy veins.
Importantly, the goal is not to remove the vein or make an incision into the scrotum. Instead, embolization closes off the abnormal vein from within the vascular system.
What Happens During Varicocele Embolization?
Varicocele embolization is typically performed as an outpatient procedure.
Before the procedure, your medical team will review your health history, medications, allergies and any relevant imaging or fertility testing. Your physician will also explain the procedure and what to expect during recovery.
During the procedure:
- A small area is numbed with local anesthetic.
- A tiny needle puncture is made in a vein, often in the upper thigh or groin.
- A thin catheter is guided through the blood vessels using X-ray imaging.
- Contrast dye is used to identify the abnormal veins and blood flow.
- An embolic material, such as a small coil or medical agent, is placed to block the affected vein.
- Blood flow is redirected through healthy veins.
- The catheter is removed and the small access site is covered.
The procedure itself generally takes about 30 to 45 minutes, although the total time at the facility can be longer because of preparation and recovery.
Depending on the individual and the practice setting, sedation may be used to help keep you comfortable. Unlike many surgical procedures, varicocele embolization does not typically require general anesthesia.
What Are the Benefits of Varicocele Embolization?
One of the biggest advantages of varicocele embolization is that it provides a treatment option without traditional surgical incisions.
Potential benefits include:
- Minimally invasive treatment: Only a small needle puncture is required rather than an incision in the groin or scrotum.
- No scrotal incision: The abnormal vein is treated from inside the blood vessel.
- Outpatient procedure: Many patients are able to return home the same day.
- No general anesthesia in many cases: Sedation and local anesthesia may be used depending on the patient and procedure.
- Short recovery: Many patients can return to normal daily activities relatively quickly.
- Treatment for pain: Embolization can help relieve pain associated with a symptomatic varicocele.
- Potential fertility benefits: In appropriate patients, treating a varicocele may improve sperm quality and other fertility-related measures.
Like any medical procedure, embolization has potential risks and is not appropriate for everyone. Possible complications can include bleeding or bruising at the access site, infection, reactions to contrast material, blood vessel injury, recurrence of the varicocele, or difficulty accessing the affected vein. Your physician can discuss the potential benefits and risks based on your individual circumstances.
Varicocele Embolization vs. Varicocele Surgery
Surgical repair, also called varicocelectomy, remains an option for treating certain varicoceles. Depending on the situation, surgery may be performed through an open, microsurgical or laparoscopic approach.
Embolization takes a different approach.
Rather than surgically accessing and tying off the affected veins, an interventional radiologist uses a catheter and imaging guidance to block the problematic veins from within.
For some men, this minimally invasive approach can offer an appealing alternative to surgery, particularly when avoiding a surgical incision and minimizing recovery time are priorities.
However, the best treatment depends on several factors, including the size and location of the varicocele, symptoms, fertility goals, previous treatments, anatomy and overall health.
How Long Is Recovery After Varicocele Embolization?
Recovery is generally shorter than with many surgical approaches. Because embolization involves a small puncture rather than a surgical incision, many patients are able to return to light daily activities relatively quickly.
Some temporary soreness, bruising or discomfort around the access site or scrotum may occur. Your physician will provide specific instructions regarding exercise, lifting and other activities following the procedure.
Many patients can resume moderate activity within approximately 24 to 48 hours, but your individual recovery may vary.
Could Varicocele Embolization Be Right for You?
If you have been diagnosed with a varicocele and are experiencing persistent scrotal discomfort, heaviness, or fertility concerns, it may be worth discussing your treatment options with a specialist.
Varicocele embolization offers a minimally invasive way to treat the abnormal veins without traditional surgery, making it an option worth considering for appropriately selected patients.
At Conrad Pearson Clinic in Memphis, our specialists can evaluate your symptoms and medical history and help determine whether varicocele embolization is appropriate for you.
