Sclerotherapy is a minimally invasive medical procedure used to treat varicose veins and spider veins. A chemical solution is injected directly into affected veins, causing them to scar and collapse. Blood is then rerouted through healthier veins, and the treated vessels gradually fade and are absorbed by the body.
Sclerotherapy treats veins affected by chronic venous insufficiency by sealing them, improving circulation, and relieving discomfort with minimal downtime. With expert, personalized care and advanced techniques, APEX Vascular helps patients in East Tennessee effectively manage CVI and restore long-term vein health.
Understanding CVI
Chronic venous insufficiency (CVI) occurs when leg veins struggle to return blood to the heart due to damaged one-way valves, causing blood to pool in the lower extremities. Common causes of CVI include:
- Valve deterioration from aging
- Genetic predisposition
- Prolonged standing or sitting
- Obesity
- Pregnancy
- Prior blood clots
These factors cause weakened vein walls and impair circulation.
Symptoms start with leg heaviness, aching, swelling (especially after standing), cramps, and restless legs. This can eventually progress to varicose or spider veins, skin discoloration (reddish-brown), itching, and thickening.
Untreated, CVI advances through inflammation and hypertension cycles. Long-term lack of treatment can lead to edema, infections, and painful ulcers near the ankles that hinder mobility and quality of life.
Early treatment for CVI relieves symptoms like pain and swelling. It’s especially impactful when paired with lifestyle changes such as exercise, weight management, leg elevation, and compression stockings.
How Sclerotherapy Works
Sclerotherapy is a minimally invasive procedure that treats diseased veins, particularly those linked to chronic venous insufficiency. It works by injecting a solution directly into them. Unlike cosmetic uses limited to surface spider veins, sclerotherapy here targets symptomatic CVI veins to improve circulation and reduce pooling.
For CVI-related varicosities, providers often use liquid sclerosants for smaller or superficial veins. Larger, deeper veins receive foam versions where the agent is whipped with gas for better adhesion and coverage.
The solution seals the vein shut by irritating the vein walls, causing:
- Inflammation
- Collapse
- Scarring
The body then naturally absorbs the faded vein over weeks while blood reroutes efficiently through healthier nearby vessels.
What To Expect During The Procedure
Sclerotherapy is a quick, outpatient procedure lasting 15-60 minutes tailored to the extent of your veins. It starts with elevating your legs for better access, followed by thorough skin cleansing to prevent infection. Your vascular surgeon then uses a fine needle to inject the sclerosant without anesthesia.
Depending on vein size and number, you may need 1-3 sessions spaced weeks apart. Discomfort is minimal, often consisting of brief cramping or stinging at injection sites that quickly fades. Compression stockings or bandages are applied immediately after to aid healing and rerouting of blood flow.
Benefits and Outcomes
Sclerotherapy offers key benefits for chronic venous insufficiency by collapsing problematic veins, which relieves:
- Pain
- Heaviness
- Swelling
It’s also used to treat bleeding varicose or spider veins on the surface. This commonly occurs when the skin becomes injured, such as being scratched during shaving or bathing.
Success rates are high for smaller veins, with visible results emerging in 3-6 weeks as the body absorbs treated vessels.
Patients enjoy cosmetic improvements as varicose and spider veins fade, alongside no downtime. This means that you can return to normal activities right away. It boosts mobility for better daily function and enhances confidence through smoother skin appearance, effectively complementing compression therapy and lifestyle measures.
Recovery and Risk Factors
Recovery is straightforward, requiring you to wear compression stockings for 1-3 weeks to support vein closure and walking regularly to help promote circulation. You should also avoid hot baths, saunas, sun exposure, or heavy exercise initially. Most patients resume work the same day, with full activity in 24-48 hours.
Sclerotherapy is generally safe with mostly minor, temporary side effects like bruising, redness, itching, or swelling at injection sites. This should resolve within days to weeks. Rare complications such as temporary pigmentation changes, lumps, or blood clots occur infrequently and are minimized by experienced providers using ultrasound guidance.
Long-Term Management
Sclerotherapy achieves permanent closure of treated veins, redirecting blood flow to healthier pathways for lasting symptom relief in chronic venous insufficiency. However, it doesn’t alter underlying factors.
Long-term management requires sustained lifestyle adjustments, like:
- Regular exercise to boost circulation
- Weight control to reduce vein pressure
- Leg elevation
- Consistent use of compression stockings
These habits prevent new vein issues from developing.
Periodic maintenance sessions may be needed for emerging varicosities, typically every 1-2 years, depending on individual risk factors. Combined with routine check-ups, this approach sustains mobility and vein health effectively.
