Varicose vein surgery aims to treat enlarged, twisted veins that cause pain, swelling, heaviness, or other complications in the legs. Depending on the severity of the condition, treatment may involve minimally invasive procedures such as endovenous laser treatment, radiofrequency ablation, or, in selected cases, conventional surgery.

An operation for varicose veins in legs is not necessary for everyone with visible veins. The right treatment depends on symptoms, ultrasound findings, the condition of the vein valves, and the patient's overall health. Understanding what happens before, during, and after the procedure can help patients prepare for treatment and recovery.

What Are Varicose Veins and Why Do They Need Treatment?

Varicose veins develop when the valves inside superficial veins become weak or damaged. These valves normally help blood travel upward toward the heart. When they do not function properly, blood can flow backward and collect in the veins, causing them to enlarge.

Common symptoms include aching legs, heaviness, ankle swelling, itching, and visible blue or purple veins. Some patients develop skin discolouration, inflammation, bleeding, or venous ulcers.

Treatment may be recommended when symptoms interfere with daily activities, complications develop, or an assessment shows significant venous reflux. A vascular specialist can determine whether treatment is appropriate and explain the available options.

Before Varicose Vein Surgery: What Should You Expect?

Preparation begins with understanding the cause of the varicose veins and identifying the most suitable treatment.

1. Consultation With a Vascular Specialist

During the initial consultation, the doctor reviews your symptoms, medical history, medications, and any previous vein treatments. They may examine your legs while you are standing to assess visible veins and swelling.

Tell your doctor if you have previously experienced blood clots, bleeding problems, allergies, or complications with anaesthesia. Also mention any medications or supplements you take, particularly blood thinners.

This information helps the specialist plan treatment safely.

2. Duplex Ultrasound Examination

 

Duplex ultrasound is an important investigation before many varicose vein procedures. It shows the structure of the veins and how blood flows through them.

The examination helps identify faulty valves, locate venous reflux, and determine which veins require treatment. It also helps the doctor distinguish superficial vein problems from other causes of leg symptoms.

The results guide the choice between laser treatment, radiofrequency ablation, foam sclerotherapy, phlebectomy, or conventional surgery.

3. Preparing for the Procedure

Your preparation instructions will depend on the treatment and the type of anaesthesia being used.

Your doctor may ask you to:

• Review your regular medications and follow instructions about any necessary changes.

• Follow specific eating and drinking instructions if sedation or general anaesthesia is planned.

• Arrange transport home if you receive sedation or cannot drive after treatment.

• Wear comfortable clothing that allows easy access to your legs.

• Ask whether compression stockings will be required after the procedure.

Do not stop prescribed blood thinners or other medications unless your healthcare professional instructs you to do so.

During the Operation for Varicose Veins in Legs

There is no single procedure used for every patient. Modern varicose vein treatment often involves closing the faulty vein from the inside rather than removing it through conventional surgery.

1. Endovenous Laser Treatment

Endovenous laser treatment uses laser energy to close an affected superficial vein.

The doctor inserts a thin laser fibre into the vein through a small puncture, usually with ultrasound guidance. Local anaesthesia is administered around the vein, and controlled heat is delivered as the fibre is withdrawn.

The heat causes the vein walls to close. Blood then redirects through healthier veins, while the body gradually absorbs the treated vessel.

This procedure is often performed as a day treatment, and many patients return home shortly afterward.

2. Radiofrequency Ablation

Radiofrequency ablation follows a similar approach but uses radiofrequency energy rather than laser energy.

A catheter is inserted into the affected vein, and controlled heat closes the vein wall. The procedure is generally performed under local anaesthesia and ultrasound guidance.

Both laser and radiofrequency treatments are commonly used for suitable patients with superficial venous reflux. The choice depends on the patient's vein anatomy, clinical findings, and the specialist's assessment.

3. Ambulatory Phlebectomy

Ambulatory phlebectomy is used to remove prominent surface varicose veins through tiny skin incisions.

The doctor uses specialised instruments to remove the affected vein segments. It may be performed alongside laser or radiofrequency treatment when larger surface veins also need attention.

Because the incisions are small, extensive surgical cuts are generally unnecessary.

4. Conventional Varicose Vein Surgery

In selected cases, conventional surgery may be recommended when minimally invasive techniques are unsuitable or unavailable.

Traditional procedures may involve ligation and stripping, in which the affected vein is tied off and a section is removed.

The technique selected depends on the location and extent of the vein disease, previous treatments, and the patient's individual circumstances.

How Long Does Varicose Vein Surgery Take?

The duration depends on the procedure, the number of veins being treated, and whether multiple techniques are combined.

Many minimally invasive treatments take approximately 30–60 minutes, although more complex procedures may take longer. Conventional surgery may require additional time and a different recovery plan.

Most minimally invasive procedures are performed without an overnight hospital stay, but this depends on the patient's health and the type of treatment.

Your specialist can explain the expected duration and whether you will need someone to accompany you home.

After Varicose Vein Surgery: What Happens During Recovery?

Recovery is generally straightforward after minimally invasive treatment, although temporary discomfort, bruising, and tightness may occur.

1. Walking After the Procedure

Patients are often encouraged to walk soon after treatment. Gentle walking supports circulation and helps reduce prolonged immobility.

Your doctor will advise when to resume normal activities and whether strenuous exercise, heavy lifting, or prolonged standing should be temporarily limited.

Extended bed rest is generally not recommended after routine minimally invasive vein treatment unless another medical condition requires it.

2. Wearing Compression Stockings

Compression stockings may be recommended after certain procedures to help manage discomfort and swelling.

The need for compression and the length of time it should be used vary according to the treatment, symptoms, and clinical circumstances. Follow the specific instructions provided by your healthcare team.

Compression should not be used without appropriate advice when significant arterial circulation problems are suspected.

3. Managing Bruising and Discomfort

Mild tenderness, bruising, or a pulling sensation along the treated vein can occur during recovery.

Your doctor may recommend suitable pain relief and provide instructions for caring for the treatment area. Keep any small puncture sites clean and follow the recommended wound care routine.

Contact your healthcare team if pain becomes severe, swelling increases significantly, or the treated area develops spreading redness, warmth, or discharge.

4. Returning to Daily Activities

Many patients return to routine daily activities within a day or two after minimally invasive procedures. Recovery may take longer after conventional surgery or when several treatments are performed together.

Avoid returning to strenuous exercise too quickly. Follow your specialist's advice about driving, work, exercise, and other activities.

A follow-up appointment may include ultrasound to confirm that the treated vein has closed and to check for complications.

What Are the Risks of Varicose Vein Surgery?

Varicose vein procedures are generally safe when appropriately selected and performed, but no procedure is entirely risk-free.

Possible complications include bruising, tenderness, skin discolouration, inflammation along the treated vein, and temporary nerve irritation. Less commonly, patients may develop infection, burns, blood clots, or deep vein thrombosis.

Varicose veins can also recur, or new veins may become enlarged over time. Treatment closes or removes the targeted veins but does not eliminate every underlying factor that contributes to venous disease.

Seek urgent medical attention if you develop sudden shortness of breath, chest pain, or significant new leg swelling, as these symptoms may indicate a serious complication.

When Should You Consider an Operation for Varicose Veins in Legs?

Treatment may be worth discussing if you experience persistent aching, heaviness, swelling, skin changes, recurrent inflammation, bleeding, or venous ulcers.

Visible veins alone do not always require an operation. A clinical assessment and, where indicated, duplex ultrasound help establish whether the symptoms are related to venous reflux and whether a procedure is likely to help.

Dr Sumit Kapadia can help patients understand the available options for varicose vein treatment and the factors that influence the choice of procedure. The recommended approach should be based on individual examination findings, medical history, and treatment goals.

Final Thoughts

An operation for varicose veins in legs can help relieve symptoms and address faulty veins when conservative measures are insufficient or complications develop. Modern treatments such as endovenous laser therapy and radiofrequency ablation often allow patients to avoid conventional vein-removal surgery.

The process begins with a specialist assessment, continues with a procedure tailored to the affected veins, and ends with recovery instructions and follow-up care.

Understanding each stage helps patients set realistic expectations and recognise when medical advice is needed. Early assessment is particularly important when varicose veins are accompanied by persistent swelling, skin changes, bleeding, or non-healing wounds.

Expert Tip: Do not choose a varicose vein procedure based on appearance or price alone. Ask whether a duplex ultrasound has identified the source of venous reflux and why the recommended treatment is suitable for your specific vein anatomy.
