Sclerotherapy is a treatment to inject a liquid solution into your veins. This solution will irritate the walls of the vein and over time will cause the vein to shrivel up and go away. It can be used for smaller veins and sometimes for larger veins. Once the vein is gone it will not return. It usually takes 3 separate treatments, about a month apart to get successful results. Please feel free to contact our office if you have further questions.

Sclerotherapy is very effective in treating spider veins. A sclerosant is injected into the veins which irritates the vein walls and causes the veins to shut down clot. The veins will look worse before better. Your body will slowly absorb the vein. If there is a more significant underlying vein problem, such as varicose veins, you want to address that before treating the spider veins.

Sclerotherapy treats spider veins by causing inflammation of the inner lining of the spider veins. This inflammation causes the vein to swell inward as well as outward which forces the blood out of this damaged abnormal vein and into healthy veins. As the spider vein heals, it scars in on itself and is absorbed by the body. It is effective because the injected medication is able to travel through the abnormal veins and make contact with the branches of these veins as well. Several injections may be required for a specific area of spider veins. Fading of the vessels may take up to 6-12 months and the goal is that the symptoms and appearance improve by 75% to 90%.

Sclerotherapy is the "gold standard" for treating medium and small sized leg veins including spider veins, due to its increased comfort, effectiveness, and safety relative to laser treatment. I often prefer lasers for spider veins of the face, neck and chest which are different from leg veins as they are very low pressure and drain downwards toward the heart. Sclerotherapy is effective in treating the inner lining (endothelium) of the veins, which effectively closes the veins. Following treatment, it is recommended that you wear compression hose when out of bed for several weeks and also avoid hot water such as baths, hot tubs, saunas, or long hot showers for 1 month. Short warm showers are not a problem.

Sclerotherapy uses a tiny needle to inject a solution into the veins. The vein lining gets inflamed and gradually closes the vein over the next several weeks. For most veins that are <4mm this is the gold standard of treatment and works the best to get rid of these veins.

Sclerotherapy solution causes the small vessels to spasm and close. It is safe and effective when done in centers with experienced physicians and nurses. In the best scenario you can expect a 70-75% improvement. Maintenance is also very important.

Sclerotherapy and laser are both effective treatments for spider veins. Sclerotherapy treats a broader area than laser treats, but with a single injection. Laser treatment treats a very small segment with each pulse.

Sclerotherapy treats spider veins by causing a chemical destruction of the lining of the vein. The spider vein scars and is no longer visible because there is no blood flow through it.

Sclerotherapy injures the inner lining of the spider vein causing the vein to thrombose. Veinwave therapy does the same thing using sound energy Ultrasound. It is similar to how opera stars break glass.

Sclerotherapy is the injection of a drug directly into veins (the "spider") flushing the blood out, rendering it less visible and scarring (sclerosing) the vein.

Sclerotherapy injections into spider veins causes an inflammatory process inside the veins which causes them to permanently occlude.

Sclerotherapy treats spider veins in the following way: when the medicine is injected into the vein, it damages the inner lining of the vein, causing the vein to close down. When a small vein is closed down completely, the body absorbs the vein and it disappears. This process can take several weeks to several months, and sometimes the spider vein requires more than one injection. That is why I tell my patients to remember the three "P"s of treating spider veins: Patience: it can take several months for the veins to fade away; Persistence: its can take several treatment sessions for some stubborn veins to close down, you have to stay with it; Payment: spider vein eradication can be expensive, ranging from a few hundred dollars to a few thousand dollars, depending on the amount of veins.

Sclerotherapy involves an injection of a sclerosant medication into the vein. This procedure has been used to treat spider veins for decades, but new painless solutions such as Asclera allow for spider veins to be treated with minimal discomfort and immediate return to activities. The procedure is performed in the office and takes approximately 30 minutes. The specially trained professional uses a very fine needle to inject a safe sclerosing agent directly into the blood vessel. The sclerosant solution displaces the blood in the vein, causing it to immediately appear lighter in color and sometimes vanish. Next, the solution irritates the vein lining, causing it to collapse, thus blocking it from getting more blood. The vein is then absorbed by the body and disappears over several weeks. Healthier vessels nearby absorb the blood flow of the collapsed veins. Sclerotherapy is preferred over laser treatment for leg veins, because there is often an underlying vein that feeds the surface spider veins. These may be too deep beneath the skin for lasers to penetrate.

Sclerotherapy destroys the endothelium (cells that line the lumen of the vein) when it comes in contact with the sclerosing agent. There are several medications used for this purpose. These solutions are injected into the veins, and a chemical phlebitis ensues, resulting in immediate thrombosis of the blood which gets trapped in the treated vein. This clotted blood should then be drained through a puncture along the course of the treated veins within two weeks to prevent staining of the skin. The circulating white blood cells clean up the debris in the ensuing months.

Sclerotherapy can be very effective in treating spider veins. The drug injected into the vein injures the cells lining the vein causing the vein to seal shut. Over time, the body absorbs the closed vein.
