Sclerotherapy treats spider veins, and it is often considered the treatment of choice for small spider veins. A solution is injected directly into the vein, which causes the vein to scar and collapse. This forces 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 up to a month to see the full results. In some instances, several treatments may be needed.
You can usually expect to see definitive results in three to six weeks. Treated veins generally do not come back, but new veins may appear. Your clinician 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 four to six weeks before undergoing another sclerotherapy session.
Studies of sclerotherapy as a treatment for spider veins indicate that it has an overall success rate of 50 to 80 percent in eliminating treated veins.
You will need to bring support hose and wear them for three to seven days following the procedure to guard against blood clots and to promote healing. You are encouraged to walk but to avoid jogging, heavy weight lifting, and “pounding” type exercises while in the healing process.
