What is spider vein and varicose vein ablation?

Varicose veins are swollen blood vessels that appear just below the surface of your skin in the lower part of your body. When your vein walls are weak, and your valves aren’t working properly, blood backs up in your veins. This causes blue and purple bumps to appear on your legs, feet, or ankles. Many treatment options may work, but varicose veins may come back.

What is varicose vein and spider vein ablation?

The vein ablation procedure is minimally invasive, using thin, flexible tubes called catheters or tiny needle injections. The vein expert applies heat or chemicals to the vein using a catheter or needle to cause tissue damage and closure. Three different kinds of ablation techniques exist:

  • Endovenous thermal ablation is a minimally invasive process that involves inserting a tiny catheter into the injured vein. Controlled heat closes the vein while the catheter is pulled out. This procedure is performed in our office.
  • Mechanical ablation. It is one of the least invasive vein closure techniques currently available. It involves inserting a small catheter that delivers a safe and effective medication or glue into the diseased vein while removing the catheter. These methods do not require multiple needle pricks; the return to normal activity is immediate. The Clariwin infusion catheter is one type of mechanical agent we use.
  • Sclerotherapy. This technique lessens the insufficiency of varicose vein insufficiency and spider veins by using minuscule needle injections of a drug that breaks the vein and is then absorbed by the body. The size and kind of veins determine how many treatments are necessary.   Normal activities may resume immediately. One kind of sclerotherapy agent we provide is Varithena. Your vein specialist will administer a tiny quantity of Varithena by direct injection or catheter. This injectable foam medication helps to close your vein.
  • Some patients report that, can veins get worse after sclerotherapy?

 When a sclerosant medication is injected into spider veins, it essentially turns them into hard scar tissue that can be very visible under the skin. This way, your spider veins will look black and bad after sclerotherapy. But your body will gradually metabolize the scar tissue, and the spider veins will disappear from the skin’s surface within three weeks. In this way, spider veins will turn black before disappearing completely.

When blood clots block veins

What Happens When Blood Clots Block Veins? If you have blood clots in your veins, you should see a doctor.

It can cause blockages, especially in your legs, lungs, or brain. If not treated promptly with anticoagulants (blood thinners) or corrective surgery, severe blood clots can be deadly.

Time for spider veins to disappear after laser treatment. For several hours, you might see redness and scars on your skin. You might notice results for small spider veins, but larger ones will become less visible over several weeks. Remember that you may need multiple sessions to remove spider veins completely.

You can ask your healthcare provider about the different treatments available. However, keep in mind that varicose veins can reoccur even after treatment. Discuss your therapy options with your provider.
