Sclerotherapy is the best treatment for varicose veins.

Definition of Sclerotherapy

Sclerotherapy injects a chemical solution into varicose and spider veins to collapse, scar, and fade them. The legs are usually treated, and results can take weeks to months, depending on vein size.

Sclerotherapy treatment

What Sclerotherapy Does

* The doctor inserts a small needle into the vein and injects fluid or foam. The lining of the inflamed vein swells shut, diverting blood to healthier veins.

* About 30–60 minutes every session. Patients can normally resume regular activities the same day, but compression stockings are recommended for 1–2 weeks.

Benefits

Visual improvement: Reduces varicose and spider veins.
Relief: Reduces varicose vein pain, swelling, burning, and cramping.
Rapid recovery: No anaesthetic; walking suggested following treatment.
It successfully removes 50–80% of treated veins in one session, while several sessions may be needed.

Risks, side effects

Minor reactions include bruising, redness, itching, swelling, and brown patches (usually transient).
Rare consequences include deep vein thrombosis, allergic reactions, and air bubbles producing headaches or visual abnormalities.
Do not use if pregnant, nursing, bedridden or having active blood clots.

Types of Sclerotherapy

Direct liquid injection sclerotherapy. Small varicose veins
Air/foam sclerotherapy improves vein contact. Larger veins
Microsclerotherapy: Tiny injections. Mini spider veins
Guided by ultrasonography for deeper veins. The invisible veins
Veins are sealed using laser energy. Minimal veins, cosmetic

The objective of sclerotherapy?

Sclerotherapy closes aberrant veins, such as varicose and spider veins, to reroute blood to healthier veins.

Main Goals

Cosmetic enhancement: Reduces or eliminates unsightly veins.
Relief: Reduces varicose vein pain, swelling, burning, and cramping.
Prevents skin ulcers and vein irritation by treating veins early.
The blood is diverted into healthier veins, and this procedure helps in better vascular health.

What Do Doctors Advise?

Non-surgical varicose veins in small to medium patients.
For non-surgical, low-downtime options.
Target remaining veins after other vein treatments.

Who Benefits?

Spider veins: Skin-visible, slender, red or blue veins.
Aching, heaviness, and swelling from varicose veins.
Patients with leg burning, itching, cramps, or edema.
After vein stripping or laser treatment, the procedure is used to remove any remaining veins.
Cosmetic seekers: Those who want vein-free legs.

Who Should Avoid It?

The surgery is delayed for pregnant or breastfeeding women.
Patients with severe vein disease or clots.
Complication-prone bedridden people.
Sclerosant-allergic patients.

Typical Candidates

Adults aged 30 to 60 years with mild to moderate venous problems.
Workers who stand or sit all day (teachers, nurses, office workers).
People with vein issues in their families.

What sclerotherapy solution is used?

Sclerotherapy uses a "sclerosant" to irritate the lining of the vein so it collapses and is reabsorbed. Vein size and location determine sclerosant choice.

Usual Solutions

Polidocanol
Un detergente sclerosante.
It's popular since it's effective and painless.
This treatment is popular for spider veins and minor varicose veins.
Tetradecyl sulfate
Another detergent sclerosing agent.
Useful for medium-sized varicose veins, stronger than polidocanol.
Saline, hypertonic
Solution of concentrated salt.
Dehydrates vein cells yet causes pain.
Pain and skin irritation make it less popular.
Chromate glycerin
Sometimes used for spider veins.
Less painful but scarcer.

Fluid vs. Foam

Small veins benefit from liquid sclerosants injected directly.
Foam sclerosants: Solutions mixed with air or gas displaces blood and coats vein walls better, good for bigger veins.

How is Sclerotherapy done?

Sclerotherapy is a quick outpatient procedure that takes less than an hour. The process is as follows:

Process Steps
Preparation
Patients lie down with slightly lifted legs.
Clean the skin, and an ultrasound may detect deeper veins.

Injection

A fine needle is used to inject polidocanol or sodium tetradecyl sulfate into the vein.
Foam sclerosants can coat bigger vein walls.
Vein Reaction
Irritating the vein lining causes swelling.
Healthy veins naturally receive blood flow.

Compression

Compression pads or stockings constrict veins and assist healing after injections.

Recovery

Patients should walk right away to improve circulation.
Normal activities can continue the same day, but avoid vigorous exercise, hot baths, and sun for 1–2 weeks.

Typical Session

Duration: 30–60 minutes.
Treatment: Multiple veins can be injected at once.
Repeated sessions may be necessary depending on vein size and severity.

Sclerotherapy Complications and Risks?

Although safe, sclerotherapy has risks and problems like any medical operation. Most adverse effects are mild and transient, but serious ones are infrequent.

Typical Side Effects

Most bruises fade within days to weeks.
Redness and swelling: Mild injection site discomfort.
Skin discolouration: Brown patches or lines fade over months.
Itching: A few days' duration.
Small skin sores: Rare but possible if the sclerosing agent escapes outside the vein.

Serious yet Rare Complications

Though rare, deep vein thrombosis (DVT) can develop.
Allergic to sclerosant solution.
Air bubbles can induce headaches, dizziness, and vision problems.
Stroke or heart problems: Rare but possible if sclerosant enters the deep venous system.

Possible Risks

Avoid the procedure if pregnant or breastfeeding.
Previous blood clots or vascular disease.
Arterial disease or poor circulation.
Chemical sclerosant allergies.

What Are Sclerotherapy Side Effects?

Typical Side Effects
Bruising at injection locations lasts days to weeks.
Redness and swelling—Mild vein irritation or warmth.
Brown lines or patches that vanish in 3–6 months.
Itching usually goes away in a few days.
Lumpiness—Larger veins may feel firm for months.
Small blood vessels—New vessels surrounding treated areas often disappear naturally.

Serious yet Rare Complications

DVT, or superficial thrombophlebitis, are blood clots.
Pulmonary embolism—A rare but life-threatening clot in the lungs.
Air bubbles can induce brief headaches, dizziness, and vision abnormalities.
An allergic reaction to sclerosant solution causes itching, swelling, or hives.
Solution leaking outside the vein might cause skin necrosis.

Possible Risks

Avoid the procedure if pregnant or breastfeeding.
Previous blood clots or vascular disease.
Chemical sclerosant allergies.
Arterial disease or poor circulation.

After Sclerotherapy Care

After sclerotherapy, veins must be cared for to mend properly and avoid problems. Doctors normally give lengthy directions, but here's a summary:

Immediate Aftercare

Wear compression stockings for 1–2 weeks to seal veins and minimize swelling.
To enhance circulation, light walking is advised following the treatment.
Avoid extended sitting/standing: Prevents leg blood pooling.

Activities to Avoid

For 1–2 weeks, avoid intense exertion.
Hot baths and saunas: Heat dilates veins and slows recovery.
Avoid black stains by protecting treated areas from the sun.

Monitoring & Following

Examine injection sites for redness, swelling, or pain beyond moderate irritation.
Return visits: Doctors may order ultrasounds or repeat sessions.
Report odd symptoms: Report severe pain, edema, or breathing problems promptly.

Lifestyle Advice

Walk regularly to improve circulation.
Leg elevation reduces edema and pain.
Maintain a healthy weight: Less vascular strain.

Sclerotherapy conclusion

Safe, effective, and minimally invasive sclerotherapy treats varicose and spider veins. Sclerosant injections collapse and fade veins, improving cosmetic appearance and symptom relief.

Sclerotherapy works best for vein pain and cosmetic enhancement. It provides long-term results and confidence with adequate aftercare and vascular specialist assistance.
