Yes, varicose veins can be removed, and today there are more ways to do it than ever. Most modern procedures are minimally invasive, performed in an outpatient setting, and require little downtime. The method that’s right for you depends on the size and location of your veins, your symptoms, and whether your insurance requires you to try conservative measures first.
Heat-Based Catheter Procedures
For larger varicose veins, the most commonly used treatments involve threading a thin catheter into the affected vein and delivering heat to seal it shut from the inside. The two main options are laser ablation and radiofrequency ablation. Both work on the same principle: heat damages the vein wall, causing it to collapse and close. Your body then reroutes blood through healthier veins nearby.
These procedures are performed under local anesthesia, typically take under an hour, and you can walk out of the clinic the same day. The success rates are excellent. Laser ablation achieves closure in 95% to 100% of treated veins at six months. Radiofrequency ablation shows a 94.5% occlusion rate at two years. At the 12-month mark, recurrence rates for both hover around 6% to 7%, with no significant difference between them. Both also produce meaningful improvements in quality-of-life scores, reducing pain, swelling, and the visible appearance of veins.
Compared to traditional surgery, catheter-based treatments cause less pain afterward and allow a faster return to normal activities. Nerve injury, which occurs in roughly 27% of patients after surgical stripping, is far less common with these approaches.
Medical Adhesive Closure
A newer option skips heat entirely. A medical-grade adhesive (cyanoacrylate glue) is injected into the vein through a catheter, sealing it shut. Because no heat is involved, there’s no need for the multiple numbing injections along the vein that thermal procedures require. This makes the experience more comfortable for many patients.
Studies show complete closure in over 90% of patients at 12 months, putting it in the same effectiveness range as heat-based methods. The complication rate is low. This approach has gained popularity quickly, though it’s still considered relatively new compared to laser and radiofrequency ablation.
Sclerotherapy
Sclerotherapy involves injecting a chemical solution directly into the vein, which irritates the vein lining and causes it to scar shut. For very small veins like spider veins, a liquid form is used. For larger varicose veins, the solution is turned into a foam that can fill and treat bigger vessels more effectively.
Foam sclerotherapy can treat a wide range of vein types, from small surface veins to larger tributaries and even saphenous trunks. However, a major trial published in the New England Journal of Medicine found that five years after treatment, patients who had laser ablation or surgery reported better disease-specific quality of life than those treated with foam sclerotherapy. Foam sclerotherapy still works well, but it may be better suited as a secondary treatment or for veins that aren’t good candidates for catheter-based procedures.
Sclerotherapy is not appropriate for everyone. It’s off-limits if you have an active deep vein thrombosis, a known allergy to the sclerosing agent, or have had a severe neurological or cardiac reaction to previous sclerotherapy. Pregnancy, breastfeeding, morbid obesity, and a high risk of blood clots are also reasons your doctor may recommend a different approach.
Traditional Vein Stripping Surgery
Before catheter-based options existed, the standard treatment was high ligation and vein stripping. This involves tying off the varicose vein where it connects to a deeper vein, then physically removing it through small incisions. A related procedure, ambulatory phlebectomy, removes smaller varicose veins through tiny skin punctures.
Surgery remains effective and still has a role, particularly for veins that are too tortuous for a catheter to navigate or in cases where other methods have failed. The tradeoff is a longer recovery and a higher chance of nerve injury. Five-year outcomes for surgery are comparable to laser ablation in terms of quality of life, so if your surgeon recommends it based on your anatomy, it’s not an inferior choice.
What Insurance Typically Requires
If your varicose veins cause symptoms, treatment is generally considered medically necessary, but insurers (including Medicare) usually require you to try conservative measures first. That means wearing compression stockings and following self-care steps like regular exercise and leg elevation for at least six weeks before a procedure will be approved.
After that trial period, coverage kicks in if you still have symptoms. The specific symptoms that qualify include pain or swelling that interferes with daily activities, skin ulcers on the lower leg, bleeding from the veins, recurring episodes of superficial vein inflammation, or skin changes from chronic venous insufficiency. For adhesive closure and certain other newer methods, insurers may also set a maximum vein diameter of 12 mm. If your veins are purely cosmetic and cause no symptoms, most insurance plans won’t cover removal.
Recovery After Treatment
Recovery from minimally invasive procedures is quick. Most people return to normal activities within a day or two. You’ll likely be asked to wear compression stockings afterward, though the recommended duration varies. Japanese clinical guidelines suggest one to four weeks of daytime compression following a few days of round-the-clock compression, and this is a common approach worldwide.
However, recent research suggests shorter compression may be just as effective. A meta-analysis found that wearing compression for at least a week reduced pain at the one-week mark and improved time off work compared to shorter durations. But beyond that initial period, longer compression showed little additional benefit. One study concluded that compression beyond two days after laser ablation using newer fiber technology may be unnecessary. Your provider will give you specific guidance based on the procedure you had and how your veins respond.
Some people experience mild bruising, soreness, or a feeling of tightness along the treated vein. About 14% to 16% of patients report some degree of chronic discomfort after heat-based procedures, though for most this is mild and manageable. Serious complications like deep vein thrombosis or nerve damage are uncommon with modern techniques.
Can Varicose Veins Come Back?
Treated veins rarely reopen, but new varicose veins can develop over time. The underlying tendency toward weakened vein valves doesn’t go away after a procedure. Factors like genetics, prolonged standing, pregnancy, and aging continue to put pressure on your venous system. Maintaining a healthy weight, staying active, and elevating your legs when resting can help slow the formation of new problem veins. If new varicose veins do appear, they can be treated with the same methods.
