Spider veins are destroyed by injecting a small amount of a chemical solution directly into the targeted vein. The chemical aggravates the vein lining, which causes it to undergo fibrosis and eventually disappear.
How long is each sclerotherapy session?
Generally, most individuals have multiple spider veins. Up to around fifteen injections can be done at one time. While each treatment session can last up to a half hour, you may need to come back for more treatments if you have more veins that need treatment. After the treatment, sterile dressings are placed over the injection site and the entire leg is covered with a bandage or wrap. The bandage is usually left on until the patient returns to see the doctor.
What are the side effects of sclerotherapy?
Besides some stinging pain, sclerotherapy rarely causes a few side effects. Allergic reactions are rare, though possible. A few individuals may develop intense itching at the site of the injection. If the chemical is injected improperly (or outside the vein), profound discoloration of the skin and pain can occur.
Can anyone undergo sclerotherapy?
Almost anyone with bothersome spider veins can be treated, but women who are pregnant or nursing should not have sclerotherapy. Patients with skin infections, fever, history of deep vein thrombosis, or anticoagulant therapy should not undergo sclerotherapy.
Is there any preparation required before sclerotherapy?
No special preparation is required before the procedure. It is recommended that you stop smoking cigarettes and stop taking aspirin a few days before the procedure. If you are on blood thinners, you are not a candidate for sclerotherapy.
Do I have to limit any activity after the treatment?
Walking is highly recommended soon after the procedure is complete. Avoid high activity sports for the first few days while your veins heal.
Is there any harm in removing spider veins?
Spider veins don’t perform any function for the body and, thus, removing them does no harm. They’re only removed because they are unsightly or bothersome, not because they do any harm to the body.
