I've Had Spider Veins for Years. Is It Too Late to Treat Them?

Maybe you first noticed them in your 30s and figured you would deal with them someday. Someday turned into a decade of long pants, careful angles in photos and a quiet assumption that the window for doing anything had probably closed. If that sounds familiar, here is the short version: spider veins you have lived with for years are still very treatable, and waiting has not ruined your options.

At Prevosti Vein Center in Canton, Dr. Louis Prevosti has treated tens of thousands of patients with venous conditions and performed thousands of sclerotherapy sessions. A number of them walk in convinced they missed their chance. They rarely have.

Is It Ever Too Late to Treat Spider Veins?

In nearly every case, no. Spider veins do not become permanent or untreatable with age. The sclerosing medication used to close them works the same way on a vein that appeared last year as it does on one that has been there for 15 years. Time alone does not set a spider vein or push it past the point of treatment. Even veins that have been visible for decades close down the same way once the medication reaches them.

What changes over time is the surrounding picture, and that is the important part to understand before you book a session.

What Changes the Longer You Wait

Spider veins are common, and they tend to accumulate rather than resolve. One large population study, the Edinburgh Vein Study, found leg spider veins in 79% of men and 88% of women, with most first appearing between ages 30 and 50. Left alone, a small patch behind one knee often becomes several patches over the years.

So the veins themselves do not expire, but a few things can shift while you wait:

• More spider veins appear, so there is simply more to treat
• Deeper feeder veins can develop and start contributing to visible surface veins
• Symptoms like aching, heaviness or itching may show up alongside the cosmetic concern

None of this closes the door to spider vein treatment. It mostly means that an evaluation after many years looks beyond the surface. Dr. Prevosti's cardiovascular and vein experience also lets him recognize when leg symptoms point to a cause beyond the veins, which is vital input if you have been noticing changes for a while.

Why Long-Standing Spider Veins Deserve an Ultrasound

Here is what many people don’t know: surface spider veins are sometimes fed by larger reticular or tributary veins sitting just beneath the skin, where you cannot see them. A fan-shaped cluster near the ankle, called corona phlebectatica, is a recognized sign of chronic venous insufficiency. When feeder veins are involved, treating only what shows on the surface tends to disappoint, because the source keeps causing new ones.

That is why Dr. Prevosti may recommend a duplex ultrasound, especially for visible veins you have had for a long time or that keep coming back. The scan maps out the veins and determines which are functioning normally and which are not, so treatment addresses the actual source rather than the surface alone. Our blog on whether spider veins signal an underlying problem goes deeper into that question.

Treating Spider Veins You've Had for Years

Sclerotherapy

For the visible surface veins, sclerotherapy remains the standard treatment. Dr. Prevosti injects Asclera, an FDA-approved sclerosing agent, directly into each vein. The medication damages the cells lining the vein wall (the endothelium) and causes the vein to close down. Your body absorbs the sealed vein over the following weeks, and the veins fade over two to three months. Treated veins often darken before they fade, which is a normal sign that they have closed.

A session runs about 15 to 30 minutes, uses no anesthesia and lets you drive yourself home and walk right afterward. Dr. Prevosti usually asks you to wear compression stockings for three days and to skip strenuous workouts, hot baths and saunas for a couple of days while the veins settle.

Ultrasound-Guided Foam Sclerotherapy

When the ultrasound shows deeper feeder veins fueling the problem, ultrasound-guided foam sclerotherapy treats those. A foam form of the same medication is guided into the reticular and tributary veins under real-time ultrasound, reaching vessels that surface injections cannot. Treating the feeders often improves how the surface veins respond and lowers the chance they refill. It also helps with spider veins that have persisted or come back after a previous round of treatment. When surface and feeder veins are present together, treating the deeper veins first often helps surface sclerotherapy work better.

What Sclerotherapy Treatment Can and Can't Do

Sclerotherapy targets the spider veins you have now, but it cannot stop new ones from forming later, since the tendency to develop them does not go away. Most people need more than one session, and results vary from vein to vein. A few stubborn veins resist injections, and in those cases, Dr. Prevosti may switch to a laser. Think of it as clearing and then maintaining rather than a one-time cure, which is a realistic and reachable goal for spider vein patients at any age. The fading is gradual, so patience is necessary: the surface veins continue to clear for weeks after each visit, and Dr. Prevosti checks your progress at follow-up before deciding whether another session is worthwhile. Wearing sunscreen on the treated areas for at least three months helps the results look their best.

"Patients apologize to me for waiting too long, and I tell them the veins didn't read the calendar," Dr. Prevosti says. "We can almost always treat them. The longer you wait, however, the more there is usually to look at underneath."
