Effective in treating both varicose and spider veins, sclerotherapy uses injectable sclerosing solution or foam that causes the vein to shrink.

What is Sclerotherapy?

Sclerotherapy effectively treats varicose and spider veins. It’s often considered the treatment of choice for small varicose veins.

Sclerotherapy involves injecting a solution directly into the vein. The sclerotherapy solution causes the vein to scar, forcing blood to reroute through healthier veins. The collapsed vein is reabsorbed into local tissue and eventually fades.

After sclerotherapy, treated veins tend to fade within a few weeks, although occasionally it may take a month or more to see the full results. In some instances, several sclerotherapy treatments may be needed.

What are the Benefits of Sclerotherapy?

  • This relatively short procedure can be performed in 30 to 60 minutes
  • Treatment is safe and may produce minor side effects such as itching or bruising that go away within days
  • Most sclerotherapy patients are able to resume normal daily activities right after treatment

Sclerotherapy Results

If you were treated for small varicose veins or spider veins, you can usually expect to see definitive results in three to six weeks. Larger veins may require three to four months.
However, multiple treatments may be needed to achieve the results you want.

Veins that respond to treatment generally don’t come back, but new veins may appear.

Your doctor will likely schedule a follow-up visit about a month after the procedure to check the procedure’s success and decide whether further sessions are needed. Generally, you need to wait about six weeks before undergoing another sclerotherapy session.

Studies of sclerotherapy as a treatment for varicose and spider veins indicate that it has an overall success rate of about 60 to 80 percent in eliminating treated veins.
