Varicose vein treatment ranges from compression stockings and lifestyle changes to minimally invasive procedures that close or remove damaged veins, usually in under an hour. The right approach depends on the size of your veins, the severity of your symptoms, and whether you’re dealing with cosmetic concerns or complications like swelling, skin changes, or ulcers.
Compression Stockings and Lifestyle Changes
For mild symptoms, graduated compression stockings are typically the first step. These apply the most pressure at your ankle and gradually decrease up the leg, helping blood flow back toward the heart instead of pooling in damaged veins. Stockings in the 15 to 20 mmHg range reduce swelling and relieve achiness. A meta-analysis of 11 trials found that this pressure level improved edema and symptoms compared to low-pressure or no compression, and that going above 20 mmHg didn’t offer additional benefit for most people.
Compression stockings work best when you wear them consistently throughout the day and remove them at night. They need replacing every few months as the elastic wears out. Beyond stockings, regular walking, elevating your legs when sitting, and maintaining a healthy weight all help reduce the pressure inside your leg veins. These measures won’t reverse varicose veins that already exist, but they can slow progression and ease discomfort enough that some people don’t need further treatment.
Sclerotherapy for Smaller Veins
Sclerotherapy involves injecting a chemical solution directly into the vein, causing it to scar shut and eventually be absorbed by the body. It’s most commonly used for spider veins and smaller varicose veins. The procedure takes 15 to 30 minutes, requires no anesthesia, and you walk out of the office afterward.
The solution can be injected as a liquid or mixed with air to create a foam. Foam sclerotherapy has a notable edge early on: in one study, 88% of veins treated with foam closed after a single session compared to 69% with liquid. By three months, the foam group still held a lead at 91% versus 77%. After multiple sessions, though, both approaches reached similar overall success rates. You may need two or three sessions spaced a few weeks apart to fully treat the affected veins.
Thermal Ablation: Laser and Radiofrequency
For larger varicose veins, especially those involving the main superficial veins of the leg, thermal ablation has largely replaced traditional surgery. A thin catheter is inserted into the vein through a small puncture, usually near the knee, and guided into position with ultrasound. The catheter then delivers heat, either from a laser fiber or a radiofrequency electrode, to seal the vein from the inside.
Both methods are highly effective. Closure rates reach about 96% for laser ablation and 90% for radiofrequency ablation, with no statistically significant difference in outcomes. The practical difference is in the recovery experience. Radiofrequency ablation tends to cause less pain on the first day. In one comparative study, patients treated with laser had an average pain score of 3.0 out of 10 the day after treatment, while radiofrequency patients averaged just 0.3. Bruising occurred in about 37% of laser-treated veins and none of the radiofrequency-treated veins. Skin darkening along the treated vein and temporary numbness were also more common after laser treatment.
Both procedures require tumescent anesthesia, a diluted numbing solution injected around the vein to protect surrounding tissue from heat. The injection itself can be uncomfortable, and it’s one of the main sources of pain during the procedure. Most people return to normal activities within a few days.
Non-Thermal Options
Newer techniques close veins without heat, which means they skip the tumescent anesthesia entirely. This makes the procedure quicker, less painful during treatment, and eliminates the risk of heat-related nerve injury or skin burns.
One approach uses a medical-grade adhesive (cyanoacrylate glue) delivered through a catheter. The glue bonds the vein walls together, triggering an inflammatory reaction that permanently seals the vein. A randomized trial comparing this adhesive system to radiofrequency ablation found it equally effective, with results sustained out to five years. Because no heat or large volumes of numbing fluid are involved, most people feel very little during the procedure.
Another non-thermal option is mechanochemical ablation, which combines two actions in a single catheter. A rotating wire tip physically damages the inner lining of the vein while simultaneously spraying a sclerosant solution. The mechanical disruption makes the vein wall more receptive to the chemical, improving closure rates. No sedation, tumescent anesthesia, or antibiotics are needed. The absence of heat means there’s no risk of thermal injury to nerves running close to the vein, which is a particular advantage when treating veins below the knee where nerves sit close to the surface.
Ambulatory Phlebectomy
Bulging, rope-like veins visible at the surface are often removed through ambulatory phlebectomy. The procedure uses tiny incisions, each only a few millimeters long, made along the path of the vein. A small hook is inserted through each incision to pull out segments of the vein. The incisions are so small they typically don’t require stitches and heal with minimal scarring, especially when made along natural skin lines.
Phlebectomy is frequently performed at the same time as thermal or non-thermal ablation. The ablation treats the underlying source of the problem (the main leaking vein), while phlebectomy removes the visible bulging branches. Most current guidelines recommend combining both in a single session rather than staging them weeks apart, since outcomes are better and patients only go through one recovery period.
Traditional Vein Stripping
Surgical ligation and stripping, once the standard treatment, involves tying off the vein at the groin and threading a wire through it to pull it out. It’s now reserved for cases where minimally invasive options aren’t suitable, such as unusually large or tortuous veins that can’t accommodate a catheter. Recovery is more involved: you’ll likely wear compression bandages for at least the first several days, avoid baths for about two weeks, and hold off on strenuous exercise like jogging or weight lifting until your doctor clears you. Most people need at least a few days off work, sometimes more depending on how physical their job is.
Risks Across Procedures
Minimally invasive vein treatments are safe overall, but blood clots are the most important risk to know about. A large analysis found that about 1.9% of patients developed a deep vein clot within seven days of thermal ablation, rising to roughly 3.1% within 30 days. Combining ablation with phlebectomy in the same session increased the rate of clot extension from the treated vein into the deep system (6% with ablation alone versus 14% when phlebectomy was added). Your treatment team will typically schedule an ultrasound within a few days of the procedure to check for clots.
Other common side effects are temporary: bruising, skin darkening along the treated vein, mild tenderness, and occasionally a pulling sensation as the vein scars down. Numbness or tingling from nerve irritation occurs in a small percentage of cases, mostly with laser ablation near the lower leg, and usually resolves within weeks to months.
What Insurance Typically Requires
Most insurers, including Medicare, cover varicose vein procedures when they’re medically necessary rather than purely cosmetic. To qualify, you generally need to meet all of the following: an ultrasound confirming that blood is flowing backward (refluxing) in your veins for at least half a second, documentation that your symptoms interfere with daily activities or quality of life, and a clinical classification showing visible vein disease. Many plans also require that you’ve tried compression stockings for a set period, often three to six months, before approving a procedure.
Spider veins treated only for appearance are rarely covered. But if your varicose veins cause pain, swelling, skin discoloration, bleeding, or ulcers, you’re much more likely to meet the threshold for coverage. Your vein specialist’s office typically handles the prior authorization process and can tell you early on whether your case is likely to be approved.
