Overview
Sclerotherapy is a safe, non-surgical treatment used to eliminate varicose and spider veins. A medicated solution is injected into the affected veins, causing them to seal shut and gradually fade as blood reroutes to healthier veins. The procedure is quick, requires no anesthesia, and helps relieve symptoms like pain, swelling, and heaviness. Depending on vein size and condition, liquid, foam sclerotherapy may be used. Results appear within weeks, with minimal recovery time.
In this complete guide, we’ll explore what sclerotherapy is, the different types available, and why it remains one of the most effective treatments for superficial varicose veins and spider veins.
What is Sclerotherapy?
Sclerotherapy is a minimally invasive vein treatment where a chemical solution (FDA approved sclerosant) is injected directly into unwanted veins. This solution irritates the vein wall, causing the lipoprotein of endothelium layer denature and stick together, and eventually collapse. Once closed off, the vein is gradually absorbed by the body and disappears from view. The blood that once flowed through that vein is naturally redirected to nearby, healthier veins. This process not only improves the appearance of varicose veins and spider veins but also reduces associated symptoms like pain, swelling, or fatigue.
What Are the Types of Sclerotherapy?
There are several types of sclerotherapy, each suited for specific vein conditions. Your provider will recommend the most appropriate option based on the size, location, and severity of your veins.
- Liquid Sclerotherapy: The most common type, using detergent-based liquid. It’s ideal for small to medium spider veins and varicose veins close to the surface. Note that the use of hypertonic saline solution as an sclerosant is a wrong practice in treating unwanted veins and is not approved by FDA for this use. Unfortunately many physicians who lack proper training are still using the very painful hypertonic saline as an sclerosant.
- Foam Sclerotherapy: In this method, the solution is mixed with air or CO2 gas to form a foam, which spreads more evenly within larger veins. Foam sclerotherapy is excellent for treating medium to large varicose veins.
- Microsclerotherapy: This advanced version targets very small spider veins using very tiny needles under magnification and polarized light. It’s often performed on the legs and face and chest areas for cosmetic improvement.
- Endovenous Laser Ablation (EVLA / EVLT): A safe and effective endovenous vein ablation method. laser treatment, EVLT is commonly complimented with sclerotherapy of secondary superficial varicose veins. It involves inserting a laser fiber, under local anesthesia, into the vein to heat and seal it from within. Patient resume normal activities immediately.
Each method offers unique benefits and may be combined for the best results depending on your vein condition.
Who Needs to Have Sclerotherapy Treatment?
Sclerotherapy is appropriate for individuals who:
- Have visible spider veins or bulging varicose veins
- Experience leg pain, heaviness, burning, or fatigue
- Are bothered by skin discoloration due to vein damage
- Want cosmetic improvement in areas like the thighs, calves, or ankles
- Have tried compression stockings or other therapies without success
Good candidates are generally healthy, not pregnant or breastfeeding. If your veins are causing discomfort or impacting your appearance, sclerotherapy could be a life-changing option. Each case is unique making the initial consultation and ultrasound evaluation a key first visit.
How is the Sclerotherapy Performed?
The procedure is simple and requires no general anesthesia. Here’s what you can expect during a typical session:
- The treatment area is cleaned with alcohol.
- Your specialist uses a fine needle to inject the sclerosant directly into the targeted veins.
- Multiple injections, which are tolerated well, may be done during one session, depending on the size and number of veins.
- After the injections, return to normal activities while compression stockings are used for 1-3 days.
Patients are encouraged to walk shortly after the procedure to support circulation. While mild very temporary swelling or bruising may occur.
How Effective is Sclerotherapy for Varicose & Spider Veins?
Sclerotherapy is one of the most effective non-surgical vein treatments available today provided it is performed by a well-educated and experienced provider.
Studies and clinical practice show:
- 90% of treated spider veins and varicose veins significantly improve after one to three sessions depending on the extent of unsightly veins.
- Foam sclerotherapy is especially successful for larger veins and may reduce the need for surgical stripping.
- Most patients experience a noticeable cosmetic and symptomatic improvement within weeks.
