Varicose veins can be eliminated through several approaches, ranging from in-office procedures that take under an hour to lifestyle changes that slow progression and ease symptoms. The right option depends on how severe your veins are, whether they’re causing symptoms, and what your insurance will cover. Most people with bothersome varicose veins are candidates for at least one minimally invasive treatment that requires little downtime.
Why Varicose Veins Form
Your leg veins contain small one-way valves that keep blood moving upward toward your heart. Every time your calf muscles contract, they squeeze blood through these valves. When the valves fail, blood flows backward and pools in the vein, stretching the walls outward. Over time, the vein becomes visibly swollen and twisted.
Valve failure usually happens because vein walls are naturally weak and dilate under normal pressure. Once the vein stretches wide enough, the two flaps of the valve can no longer meet in the middle, so they stop sealing. This creates a loop where blood travels up through healthy veins and back down through damaged ones, slowing circulation in the leg. Direct injury or inflammation from a blood clot near the surface can also destroy valves outright. Genetics, pregnancy, prolonged standing, and obesity all raise the risk.
Start With Conservative Measures
Before covering any procedure, most insurers (including Medicare) require a three-month trial of conservative treatment. Even if you’re paying out of pocket, these strategies reduce symptoms and can prevent new varicose veins from forming.
Compression stockings are the cornerstone. Medical-grade stockings come in low pressure (under 20 mmHg), medium pressure (20 to 29 mmHg), and high pressure (30 to 40 mmHg). Over-the-counter options from pharmacies are typically 10 to 15 mmHg, which is enough for mild discomfort. For established varicose veins, your doctor will likely prescribe 20 to 30 mmHg or higher. The stockings work by squeezing your veins narrower so the valves can close more effectively and blood moves upward instead of pooling.
Leg elevation uses gravity to drain pooled blood. Elevate your feet above the level of your heart three or four times a day for about 15 minutes each session. Propping your legs on a pillow while lying on the couch works well. This is especially helpful after long periods of standing or sitting.
Movement and exercise activate your calf muscles, which act as a pump for venous blood. Walking, cycling, and swimming are all effective. If your job keeps you seated or standing in one spot, take short walking breaks throughout the day. Weight loss, when relevant, also reduces pressure on leg veins.
Thermal Ablation: Laser and Radiofrequency
Thermal ablation is one of the most common ways to permanently close a varicose vein. A doctor threads a thin catheter into the damaged vein using ultrasound guidance, then delivers heat (either laser energy or radiofrequency waves) to seal it shut. Your body reroutes blood through nearby healthy veins. The procedure is done under local anesthesia in an office or outpatient center, typically in under an hour.
You won’t feel pain during the procedure. Afterward, you can expect some soreness, tingling, or bruising near the treated area, usually manageable with over-the-counter pain relievers. Most people return to work within a few days, though physically demanding jobs may require a longer break. You’ll be told to walk frequently during recovery but avoid strenuous exercise and air travel for about two weeks.
Both laser and radiofrequency ablation have high success rates. In a study of over 430,000 procedures, the risk of deep vein thrombosis (a blood clot in a deeper vein) within 30 days was about 3.1%, with laser ablation carrying a slightly lower risk (2.8%) than radiofrequency (3.4%). Your doctor will have you wear compression stockings afterward and may schedule follow-up ultrasounds to check for clots.
Medical Adhesive (VenaSeal)
VenaSeal uses a medical-grade adhesive to glue the varicose vein closed from the inside. A catheter delivers small amounts of the glue, which hardens on contact with tissue and blood, sealing the vein permanently. The body eventually surrounds the sealed vein with scar tissue, locking it shut for good.
In the pivotal trial submitted to the FDA, VenaSeal successfully closed the treated vein in 99.1% of patients at three months and 96.7% at one year, matching the results of radiofrequency ablation. The key advantage is that VenaSeal doesn’t require the multiple anesthetic injections along the vein that thermal methods need, which means less discomfort during the procedure. It also doesn’t require compression stockings afterward in most cases.
Sclerotherapy
Sclerotherapy involves injecting a chemical solution directly into the vein, irritating the lining and causing it to collapse and scar shut. It’s most commonly used for smaller varicose veins and spider veins. Larger veins can be treated with foam sclerotherapy, where the solution is mixed with air to create a foam that spreads more effectively through the vein and requires a smaller dose of the sclerosing agent.
Sessions are quick, usually 15 to 30 minutes, and don’t require anesthesia beyond what the solution itself provides. You may need multiple sessions spaced a few weeks apart for complete results. Compression stockings are typically worn for one to two weeks after each session. Bruising and temporary skin discoloration at the injection site are common.
Mechanochemical Ablation
Mechanochemical ablation combines a spinning wire tip with a sclerosing injection. The rotating wire damages the inner lining of the vein while the chemical solution seals it. This approach avoids the heat of thermal ablation, so it doesn’t require the numbing injections along the length of the vein.
Short-term results are promising, but long-term data tells a more cautious story. In a study with an average follow-up of over eight years, the anatomical success rate dropped to about 60.5%. That’s notably lower than thermal ablation over similar timeframes. Mechanochemical ablation may be a reasonable choice if you want to avoid heat-based treatments, but the higher chance of the vein reopening is worth discussing with your doctor.
Traditional Vein Stripping
Surgical stripping, where the vein is physically removed through small incisions, was the standard treatment for decades. It’s now less common because minimally invasive options achieve similar results with less pain, smaller scars, and faster recovery. However, stripping is still used for very large or unusually tortuous veins where a catheter can’t be threaded through effectively. Recovery takes one to two weeks, and it’s typically done under general or regional anesthesia.
What Insurance Requires
Insurance coverage hinges on whether your varicose veins are considered medically necessary or cosmetic. Purely cosmetic treatment is not covered. To qualify, you’ll need to meet specific criteria.
First, you must complete a three-month trial of conservative measures: compression stockings, exercise, leg elevation, weight management, and avoiding prolonged immobility. If symptoms persist after that trial, coverage kicks in when you have at least one of the following: pain, aching, cramping, burning, or swelling that limits your activity; recurrent surface-level vein inflammation; non-healing skin ulcers; bleeding from a varicose vein; skin changes from chronic blood pooling; or swelling that won’t resolve with conservative care.
For thermal ablation specifically, the vein must also meet size and anatomy requirements. Radiofrequency ablation is covered for veins up to 20 mm in diameter, while laser ablation covers veins up to 30 mm. The vein can’t have blood clots or be so twisted that a catheter can’t pass through it. Your doctor will document all of this with an ultrasound before submitting for authorization.
Choosing the Right Treatment
For large, straight veins in the thigh or calf, thermal ablation (laser or radiofrequency) remains the gold standard, with strong long-term closure rates and relatively low complication risk. VenaSeal is a good alternative if you want to skip the numbing injections and post-procedure compression stockings. Sclerotherapy works best for smaller veins and spider veins, or as a follow-up to ablation for remaining visible branches. Mechanochemical ablation is an option for people who can’t tolerate heat-based treatments, though reopening rates are higher over time.
Many people need a combination. A typical treatment plan might involve thermal ablation or VenaSeal for the main trunk vein, followed by sclerotherapy sessions for the smaller branching veins that remain visible. Your vein specialist will map your venous system with ultrasound and recommend a tailored approach based on where the valve failure is occurring and how extensive it is.
