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.
