I Had Sclera Treatment for my Veins Last Friday and Have Pea-sized Lumps That Have Come Up Behind my Knee?

Our patients use Venasmart compression after sclerotherapy. See your vein surgeon about possible blood clot evacuation. Best, Dr. KaramanoukianLos Angeles

Every drug will have side effects and may affect different patients in different ways. Overall, Asclera is tolerated well and is effective for most people who want to reduce the appearance of visible veins, but if you experience a complication from this treatment or any medical treatment and are in pain, you should go to an emergency room to take the most cautious approach and get a proper medical diagnosis. This is especially true when you are having an issue with a vital system of the body such as the circulatory system.

Thank you for your question. If you're having intense pain, ankle swelling, and pain when walking, I would recommend going to the emergency room to get treated immediately. I hope this helps.

It is normal depending on the size of the vein to get little lumps after sclerotherapy and this can happen quite often.  We usually recommend coming back within a week or so after the procedure to have these veins nicked with a tiny needle and these tiny clots expressed.  IF they are not removed, they often can cause discoloration of the skin and take a long time to fade.  You should return to the place that injected you and discuss aspiration of these micro thrombi

What you are describing are tiny blood clots that form in the treated veins. These can resolve on their own but will take some time and may result in hyperpigmentation in the area. Also, you can go back to the center and they may be able to remove the clot with a tiny needle and pressure. .

Following sclerotherapy clot will form in the injured vein.  If the vein is superficial and large enough, it will be hard following treatment due the clot within it (whereas previously it was "squishy" with normal blood). Eventually these do improve, but can be tender and even develop discoloration for weeks to months if the clot is not evacuated.  The clot can be evacuated with a needle or small incision, or a mini-phlebectomy to remove the damaged vein.  These are not deep blood clots, or clots that can cause harm. 

These lumps are areas of blood trapped in veins that were treated, and are now collapsed. Patients should return in 3-5 weeks to have any persistently trapped blood removed to speed healing.

A lower extremity venous ultrasound could confirm ifany complication like blood clots from the treatment is causing your problem andthis test can be done in the emergency room. If there are other symptoms likepain and swelling you should go to the emergency room. Otherwise follow up with a physician or specialist. best,

These are retained coagulum, old blood, in the superficial veins and likely from not wearing compression stockings after the pprocedure. They need to be drained in order to reduce hyperpigmentation. Asclera and almost all sclerosant solutions can cause this to occur.

Hi Dear
Sclerotherapy procedure is very interesting, when the sclerosing agent is injected into the vein, the inner lining of the vein get stripped from endothelium (inner lining wall of the vein ) causing the wall of the vein become sticky and when compression stocking is put on and it is wrapped, the pressure will cause the vein walls attach to each other and scar (healing) process starts. Usually it takes 3-6 months the scar issue formation and absorption of the scar by our body. One major factor is that the red blood cells are very small and might travel back to the vein and you might see the vein again but does not mean that process has not started. I recommend compression stocking for three weeks around the clock. And sometimes the RBS gets trapped in the vein even though the vein is closing and I usually take the blood out so heal faster.
Thank you
