Varicose veins can be treated with approaches ranging from compression stockings and lifestyle changes to in-office procedures that close or remove damaged veins, often in under an hour. The right treatment depends on the size and location of your veins, the severity of your symptoms, and whether the underlying valves in your deeper veins are leaking. Most people with symptomatic varicose veins are candidates for minimally invasive procedures that have largely replaced traditional surgery.
Why Varicose Veins Develop
Veins in your legs contain one-way valves that push blood upward toward your heart. When those valves weaken or fail, blood pools and flows backward, a condition called venous reflux. The increased pressure stretches the vein walls, producing the bulging, ropy appearance of varicose veins. Standing or sitting for long periods, pregnancy, obesity, and aging all increase the likelihood of valve failure. Genetics play a significant role too: if both parents had varicose veins, your chances are substantially higher.
How Varicose Veins Are Diagnosed
A visual exam can identify varicose veins on the surface, but treatment decisions depend on what’s happening deeper in the leg. Doctors use a duplex ultrasound, a painless scan that maps blood flow in real time, to locate which valves are leaking. The key measurement is how long blood flows backward after the calf is compressed and released. In most leg veins, backward flow lasting longer than half a second is considered abnormal. For the larger veins near the groin and behind the knee, the threshold is one second. These measurements determine which veins need treatment and which approach will work best.
Conservative Treatments
For mild symptoms like achiness, swelling, or heaviness at the end of the day, conservative measures are typically the first step. Graduated compression stockings apply the most pressure at the ankle and gradually decrease up the leg, helping blood move upward more efficiently. Most insurers require a trial of compression stockings, usually lasting three to six months, before they’ll approve a procedure.
Regular walking and calf exercises activate the muscle pump that assists blood flow. Elevating your legs above heart level for 15 to 30 minutes several times a day reduces swelling. Losing excess weight lowers the pressure on leg veins. These strategies won’t reverse existing varicose veins, but they can slow progression and relieve discomfort enough that some people don’t need further treatment.
Horse chestnut seed extract is the most studied herbal supplement for venous symptoms. The active compound helps reduce fluid leaking through vein walls, which decreases swelling and leg heaviness. Standardized extracts are available over the counter, but this supplement can interact with blood thinners and other medications.
Endovenous Thermal Ablation
Thermal ablation is the most common procedure for larger varicose veins and the refluxing trunk veins that feed them. A thin fiber or catheter is threaded into the damaged vein through a tiny needle puncture, guided by ultrasound. The device then delivers heat (either laser energy or radiofrequency energy) to seal the vein shut from the inside. Your body reroutes blood through healthy veins nearby.
The procedure is done under local anesthesia in an office or outpatient setting and takes 30 to 60 minutes. Endovenous laser ablation closes the treated vein successfully in about 88.5% of patients at one year, comparable to traditional surgical stripping. The risk of serious complications is low: deep vein thrombosis occurs in roughly 0.3% of cases within the first month, and pulmonary embolism in about 0.07%.
Most people walk out of the office immediately and return to normal activities within a day or two. You’ll wear compression stockings for one to two weeks afterward. Bruising and mild soreness along the treated vein are common and typically resolve within a few weeks. Doctors generally recommend avoiding heavy lifting and vigorous exercise for about a week after the procedure.
Medical Adhesive Closure
A newer alternative to heat-based treatments uses a medical-grade adhesive to seal the vein shut. A catheter delivers small amounts of glue inside the vein, and the doctor applies external pressure to close the walls together. The adhesive hardens on contact with tissue, stopping blood flow through the damaged vein permanently.
The main advantage is that it doesn’t require the multiple numbing injections along the vein that thermal ablation does, making the experience more comfortable. In the pivotal clinical trial submitted to the FDA, the adhesive system closed the target vein in 99% of patients at three months, compared to 95.4% for radiofrequency ablation. At one year, both methods showed identical closure rates of 96.8%. Because no heat is involved, there’s virtually no risk of nerve injury, a rare but possible side effect of thermal ablation near certain areas of the lower leg.
Foam Sclerotherapy
Sclerotherapy involves injecting a chemical solution directly into the vein, which irritates the lining and causes it to collapse and eventually be absorbed by the body. The foam version of this treatment is used for larger varicose veins because the foam displaces blood and maintains better contact with the vein wall than liquid alone.
It’s the least invasive option and requires no anesthesia, just a series of injections through a small needle. However, it has a lower success rate than thermal ablation: about 72% of treated veins remain closed at one year. Some veins reopen over time and need repeat sessions. Foam sclerotherapy works well as a complementary treatment, used alongside ablation to address smaller branching veins that remain visible after the main trunk vein is sealed.
The most common side effect is temporary skin discoloration along the treated vein, which can take months to fade. Allergic reactions to the sclerosing agent are rare.
Ambulatory Phlebectomy
For large, bulging veins that sit close to the skin’s surface, phlebectomy physically removes them through tiny incisions, each just a few millimeters long. The procedure is done under local anesthesia, and the incisions are small enough that they usually don’t require stitches.
Phlebectomy is often performed during the same visit as thermal ablation: the ablation seals the deeper trunk vein, and phlebectomy removes the visible surface veins. Most people resume normal daily activities within 24 hours and return to work in one to two days. This approach isn’t appropriate if the problematic veins are deep inside the leg, if you have an active skin infection, or if you’re at high risk for blood clots.
Choosing the Right Treatment
The choice between procedures depends on several factors. Thermal ablation and medical adhesive closure are best suited for the long, straight trunk veins (like the great saphenous vein) that run the length of the inner thigh and calf. Foam sclerotherapy works well for medium-sized veins and spider veins, or for treating branches left over after ablation. Phlebectomy is ideal for large surface veins that are too big for sclerotherapy but too superficial or winding for catheter-based treatments.
Many people end up with a combination. A typical treatment plan might involve ablation of the main leaking vein, followed by sclerotherapy or phlebectomy for the visible branches a few weeks later. Your doctor will use the ultrasound findings to map out which veins to target and in what order.
Insurance and Cost Considerations
Insurance coverage for varicose vein treatment hinges on whether it’s considered medically necessary or cosmetic. If you have documented symptoms like pain, swelling, skin changes, or ulcers, and your ultrasound confirms venous reflux, most plans will cover treatment. Purely cosmetic treatment of veins that don’t cause symptoms is generally not covered.
Most insurers require you to complete a supervised trial of compression stockings before approving a procedure. They also require ultrasound evidence showing the specific veins that are refluxing. Keep records of your symptoms, any complications like skin discoloration or bleeding, and the dates you wore compression stockings. Getting prior authorization before scheduling a procedure prevents unexpected bills.
What to Expect After Treatment
Regardless of which procedure you have, treated veins don’t disappear overnight. The sealed or collapsed vein is gradually absorbed by your body over weeks to months. Bruising, mild tenderness, and a sensation of tightness along the treated area are normal in the first week or two. Compression stockings after the procedure help reduce swelling and support healing.
Walking is encouraged from day one. It activates the calf muscle pump and promotes healthy circulation through the remaining veins. Most people feel noticeably better within two to four weeks, with reduced heaviness and swelling. Full cosmetic improvement, where the visible veins fade or disappear, can take three to six months.
Varicose veins can recur in other veins over time because treatment doesn’t fix the underlying tendency toward valve weakness. Maintaining a healthy weight, staying active, and wearing compression stockings during prolonged standing or sitting can help slow the development of new varicose veins.
