Varicose Vein Treatment: Is Radiofrequency Ablation Right for You?
"Explore the five-year outcomes of monopolar vs. segmental radiofrequency ablation for varicose veins and make an informed choice about your treatment options."
Varicose veins, those twisted, enlarged veins near the surface of the skin, are a common problem, affecting a significant portion of the adult population. While various treatments exist, radiofrequency ablation (RFA) has emerged as a popular minimally invasive option.
RFA works by using heat generated from radiofrequency energy to collapse and seal off the affected vein, redirecting blood flow to healthier vessels. Two primary types of RFA exist: monopolar and segmental. Monopolar RFA uses a single electrode to deliver energy, while segmental RFA delivers energy in controlled segments along the vein.
If you're considering RFA for varicose veins, understanding the long-term outcomes of these two approaches is crucial. This article will delve into a comparative analysis of five-year results from a study evaluating monopolar and segmental RFA, providing you with the information needed to discuss treatment options with your doctor.
The Scale of Varicose Vein Disease
In a claims database covering 45,821,615 people, 985,632 patients had a diagnostic claim for varicose veins during the analysis period. Separate U.S. estimates report that more than 40 million people have varicose veins, while almost 50% of patients are reported to have a family history of the condition. A 2026 epidemiological analysis recorded 1,211,689 surgeries for chronic venous disease between 2015 and 2023, averaging 6.43 procedures per 10,000 people.
Treatment Depends on the Patient
Patients with varicose veins may receive conservative or surgical treatment depending on their clinical condition and preferences. Described options include conservative care, endovenous laser ablation, sclerotherapy, and phlebectomy. Treatment comparisons note that some procedures require tumescent anesthesia and may cause soreness for one to two weeks, while sclerotherapy may require multiple sessions and may be less effective for large veins.
From Ancient Puncture to Modern Intervention
The history of varicose vein treatment reaches back to Hippocrates, who recommended puncturing varicosities at multiple points before 300 BC. Historical accounts describe an evolution in which varicosities were cauterized, twisted, poked, avulsed, ligated, divided, and stripped. Later developments progressed from crude surgical procedures toward laser interventions and other modern techniques.
Monopolar vs. Segmental RFA: Understanding the Differences
The study, published in International Angiology in December 2018, compared the efficacy and safety of segmental RFA (using the Venefit system) and monopolar RFA (using the EVRF system) in treating lower extremity varicose veins. Researchers followed 193 patients who underwent either procedure between 2010 and 2012, tracking their progress for five years.
- Segmental RFA (Venefit): A catheter is inserted into the vein, and radiofrequency energy is delivered in short, controlled bursts to specific segments of the vein wall. This creates targeted heating, causing the vein to collapse and seal shut.
- Monopolar RFA (EVRF): A single electrode is used to deliver radiofrequency energy along the entire length of the targeted vein. The heat generated causes the vein to close.
Evidence Behind Modern Treatment
A 2024 narrative review examines varicose vein anatomy, pathophysiology, and modern treatment options, with particular attention to endovenous approaches. A systematic review and meta-analysis found low-quality evidence supporting the long-term safety and efficacy of surgery, while short-term studies supported the efficacy of less invasive treatments. Another systematic review informing Society for Vascular Surgery guidance analyzed 45 randomized controlled trials, 28 observational studies, and one systematic review.
Benefits Do Not Eliminate Risk
MedStar Health describes both sclerotherapy and endovenous ablation as well-tolerated, low-risk procedures intended to provide relief with minimal downtime. However, the American Academy of Family Physicians reports that a 2014 Cochrane review found endovenous laser ablation, radiofrequency ablation, and foam sclerotherapy as effective as surgery, rather than establishing that they are risk-free. Varicose veins themselves may involve pain, swelling, skin changes, and a risk of deep vein thrombosis.
Comparing the Main Options
Available treatments include foam sclerotherapy, laser therapy, and surgical vein stripping. Foam sclerotherapy is less invasive than laser ablation or surgery, but it may need to be repeated to completely diminish the veins. Current treatment listings also include sclerotherapy, ultrasound-guided sclerotherapy, and endovenous laser ablation.
Making an Informed Decision About Your Vein Health
The study suggests that both segmental (Venefit) and monopolar (EVRF) RFA are effective and safe options for treating varicose veins. The five-year occlusion rates and VCSS score improvements were comparable between the two groups.
Individualized Decisions Matter
A systematic review concluded that low-quality evidence supports the long-term safety and efficacy of surgery, while short-term studies support the efficacy of less invasive treatments. The choice of treatment therefore benefits from an individualized evaluation rather than a single universally preferred procedure. A second opinion may help confirm the diagnosis, personalize the care plan, and increase confidence in the treatment decision.
Toward Less Invasive Care
Future device development is described as moving toward maximum efficacy with minimum intervention through 2032. A 2024 review says treatment trends are shifting toward minimally invasive procedures, with emphasis on patient comfort and faster recovery. One market forecast projects that the varicose veins treatment market will grow from USD 1.49 billion in 2026 to USD 2.41 billion by 2035, representing a 5.50% compound annual growth rate.
Recurrence and Venous-System Differences
Long-term follow-up reports place recurrence after varicose vein surgery at 25% to 70% after five to ten years. The underlying venous system also matters: deep-system disease is often refractory to treatment, whereas superficial-system disease can usually be treated by ablating refluxing vessels. These differences help explain why outcomes and treatment strategies vary among patients.
Patient Outcomes in Practice
A 2025 study examined 16-month closure rates and safety for the VenaSeal system in lower-limb varicose vein surgery. A Varithena case study describes a 52-year-old woman with bilateral tired and heavy legs and a history of bleeding varicosities. Another patient account reports remaining varicose-vein-free for 18 years after modern treatment and dedicated follow-up care.
If you're considering RFA, discuss the potential benefits and risks of each method with your doctor. Factors such as the size and location of your varicose veins, your overall health, and your personal preferences will help determine the best treatment approach for you.
Ultimately, the goal is to improve your vein health, alleviate symptoms, and enhance your quality of life. By understanding the available treatment options and working closely with your healthcare provider, you can make an informed decision and achieve the best possible outcome.
