What happens to the vein after sclerotherapy?

Since veins no longer work after sclerotherapy treatment, what happens to them?

Sclerotherapy is the injection of a medical grade sclerosant that is used to remove the inner endothelial lining of the vein. This typically causes the vein to spasm and close, which can either be temporary or permanent. If blood flow is restored to the treated vein then the vein will be repaired and not appear to have changed. That is why it is recommended that after the sclerotherapy you wear compression hose and avoid hot water which can reopen the closed veins. If the veins remain closed for about 4-6 weeks, then they will be reabsorbed over time. New veins grow easily and quickly when ever needed.

After sclerotherapy your veins that are treated will shrink and then dissolve.

The sclerosant closes the lumen of the vein by forming a thrombus, this thrombus may recannalize requiring additional sclerotherapy or remain totally occluded, eventually being replaced by scar tissue.

When the veins are injected with a sclerosing solution, the lining of the vein is damaged (veins get their nourishment from the blood which flows through them) and they collapse and are eventually absorbed by the body. Any blood which flowed through those veins is re-routed to surrounding healthy veins, of which there are many. It is not a rapid process and can involve several treatments to get all the vein and ensure those which appear sealed are completely seal. If not the blood can re-open areas.

Sclerotherapy "scleroses" the vein, creating scarring within the vein so that it no longer has blood in it, thus becoming "invisible."

The body digest the veins.
