How long does it take for the vein to break down after sclerotherapy?

Is the vein supposed to close down right after getting the injections or does it take a while to do so?

Sclerotherapy: recovery and results

It will take up to 2 months before you see full results. If necessary to treat again wait 2 months, no earlier. You should expect at least 50-75% improvement of overall appearance with each treatment. Most patients may need between 2 to 6 treatments. If there is no improvement, consider to be re-assessed for venous insufficiency including ultrasound of your legs by your board certified vein specialist. 


Timing of healing after sclerotherapy

Eaarly on, sclerosant solutions cause chemical injury of the endothelial lining of the vein which results in thrombosis with retenton of coagulum, the degree of which depends on the adequacy of compression. Within 12 weeks, this coagulum will be absorbed and the vein will sclerose down (scra down).

It is very important to use adjunctive topicals to reduce overlying hyperpigmentation.

Make sure you use the following topicals to reduce likelihood of hyperpigmentation of the overlying skin. 

You need to use some adjunctive measures after sclerotherapy to reduce post inflammatory hyperpigmentation. it is those that don't follow such instructions immediately following sclerotherapy, starting on day1 (next day) that seem to get retained hyperpigmentation. I recommend 2 creams: Scleroquin plus and Sclerovase and also Scler-X supplement to reduce post inflammatory hyperpigmentation (see link below) as well as compression stockings for at least 2 weeks.

Thank you for your question in regards to sclerotherapy. The veins will begin to close down and you should see improvement within 8-10 weeks, as long as post-care instructions are followed and compression was worn. To be sure what is best for you, see two or more board-certified providers in your area for a complete evaluation to make sure you are a good candidate and that it is safe for you to have treatment. I hope this helps.

Thank you for your question. Sclerotherapy involves an injection of a chemical that will cause your vein to contract and become scarred internally. The vein will disappear from your body after some time. Generally, it takes about 8-10 weeks for the vein to disappear. Please make sure you seek treatment from a board-certified dermatologist.

Sclerotherapy and what to expect

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}
Sclerotherapy involves an injection of a solution directly into those visible veins, and while they will begin to close immediately, full results won’t be seen until after a 12-16 weeks when the body has enough time to eat up of the vein.
During the first week, you’ll need to wear compression stockings in order to prevent the veins from refilling with blood. Sclerotherapy is considered the gold standard for superficial reticular and telengiectatic vein destruction, as it is a quick, safe, and effective procedure that involves minimal downtime and discomfort.

Expectations after sclerotherapy

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}

Generally sclerotherapy improves the appearance of unsightly veins but generally can get a bit worse before the vein closes off and fades away.  This time period last about a 1 week and can extend several months if discoloration appears.  Compression along with proper concentration and technique can speed up the recovery and improve outcome. Several treatments may be needed to get the desired appearance.

Wearing compression stockings will help with resolution of the veins after sclero. I would start with Venasmart compression stockings as soon as possible. It may take weeks to resolve.

Depending on the product used for the sclerotherapy and how your body is reacting to it, it can take anywhere from two weeks to a month to start seeing some results. Keep in mind, depending on the skill level and expertise of the surgeon, you may or may not see results off of the first try. It is important to be consistent with your treatments to get the best results.

Time for veins to breakdown after sclerotherapy

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}

Most veins will be cleared by 4-6 weeks, but some can take as much as 10-12 weeks to clear. As far as reinjecting a vein that has been treated, visual inspection can be used to make a decision, but I generally don't reinject prior to 6 weeks.

How long does it take for a vein to break down after sclerotherapy?

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}

Thank you for your question.  I generally tell patients it can take up to 4 weeks for a vein that is injected to go through it's entire process of breaking down and healing.  I don't reinject an area for at least 4 weeks after the last sclerotherapy treatment.  Spider veins may need to be injected after 4 weeks of the first spider vein treatment in to take care of any remaining spider veins.  Best of luck to you!
