How Does the Varicose Vein Treatment Process Work?

How does the varicose vein treatment process work?

The varicose vein treatment process is a step-by-step pathway that begins with an accurate diagnosis and is planned individually for each patient.

At Dr. İlker Zan’s clinic, the process generally includes a detailed consultation, color Doppler ultrasound assessment, selection of the most appropriate treatment method, the procedure itself, and follow-up after treatment.

This page explains the main stages of the varicose vein treatment process from the first examination to recovery and follow-up.

Varicose veins develop when superficial leg veins become enlarged and tortuous, often because the valves inside the veins do not function properly and venous reflux develops. Symptoms may include pain, heaviness, itching, swelling, night cramps, and visibly enlarged veins.

The treatment process is individualized according to the type and extent of the venous problem, the findings on Doppler ultrasound, the patient’s symptoms, and general clinical condition.

1. Initial consultation and symptom assessment

The first step is a detailed medical history.

During the consultation, information may be collected about:

  • How long the symptoms have been present
  • Whether the patient stands or sits for long periods
  • Previous pregnancies
  • Family history of varicose veins
  • Previous deep vein thrombosis or other venous problems
  • Previous varicose vein treatments
  • Pain, burning, heaviness, night cramps, swelling, itching, or cosmetic concerns

This first assessment helps determine whether further venous evaluation is required and which parts of the venous system should be examined more closely.

2. Physical examination

The legs are examined clinically, usually while the patient is standing and in other positions when necessary.

The doctor evaluates the type and distribution of visible veins, including:

  • Spider veins
  • Reticular veins
  • Larger varicose veins
  • Swelling
  • Skin discoloration
  • Signs of venous eczema
  • Venous ulcers or previous ulcer scars

The physical examination is important, but visible veins alone do not always reveal the source of the venous problem.

3. Color Doppler ultrasound assessment

A detailed color Doppler ultrasound examination may be performed to identify the source of the varicose veins and assess the superficial and deep venous systems.

The examination can provide information about:

  • Direction of venous blood flow
  • Venous reflux
  • Valve function
  • Saphenous vein insufficiency
  • Perforator vein insufficiency
  • The condition of the deep venous system
  • Evidence of current or previous thrombosis

This stage is important because the treatment plan should be based not only on the visible veins but also on the underlying venous anatomy.

4. Determining the type of venous problem

The findings from the clinical examination and Doppler ultrasound are considered together.

The visible venous changes may include:

  • Spider veins / telangiectasias
  • Reticular veins
  • Larger superficial varicose veins
  • Varicose veins associated with saphenous vein insufficiency
  • Varicose veins associated with perforator vein insufficiency
  • Venous changes associated with deep venous disease

These different patterns do not necessarily require the same treatment.

For this reason, identifying the type and source of the venous problem is one of the most important stages of the varicose vein treatment process.

5. Planning the treatment

The treatment method is selected according to the patient’s venous anatomy, symptoms, Doppler findings, and clinical needs.

Depending on the individual case, treatment options may include:

Sclerotherapy and foam sclerotherapy

Sclerotherapy involves injecting a sclerosant into selected veins in order to damage the inner vein wall and cause the treated vein to close over time.

Foam sclerotherapy may be used in suitable veins depending on their size, location, and anatomy.

Endovenous laser and radiofrequency ablation

Endovenous laser ablation and radiofrequency ablation are minimally invasive techniques used in suitable patients to close incompetent superficial veins with venous reflux.

These procedures are performed through a catheter inserted into the vein, generally under local or tumescent anesthesia.

Ultrasound-guided sclerotherapy

Deeper or less visible veins may sometimes be treated under ultrasound guidance. This allows the target vein and the position of the needle to be visualized during treatment.

Treatment of incompetent perforator veins

In selected patients, incompetent perforator veins may contribute to venous reflux and may require specific treatment.

Transdermal laser treatment

Small superficial vessels and selected spider veins may be treated with transdermal laser depending on their size, depth, and color.

CLaCS treatment

CLaCS combines transdermal laser, skin cooling, and sclerotherapy in selected patients with superficial veins and spider veins.

Surgical treatment

Traditional surgical techniques such as stripping or mini-phlebectomy may still be considered in selected cases.

However, many patients with superficial venous reflux can now be treated with minimally invasive techniques depending on their anatomy and clinical findings.

Medical and conservative treatment

Medication, compression therapy, walking, exercise, weight management, and lifestyle measures may be used as supportive treatment when appropriate.

These measures may help control symptoms, but they do not necessarily eliminate the underlying venous reflux.

6. Preparation before treatment

Before the procedure, the venous map and treatment plan are reviewed.

Patients are informed about:

  • The planned procedure
  • Medications that may need to be discussed before treatment
  • Skin and leg preparation
  • Compression stockings if required
  • Walking and activity after treatment
  • Possible temporary side effects
  • Follow-up appointments

Preparation may vary depending on the type of treatment.

7. The day of the procedure

Many minimally invasive varicose vein procedures can be performed without general anesthesia.

Depending on the method, local anesthesia or tumescent anesthesia may be used.

The duration of the procedure varies according to the number of veins being treated and the technique used. Many patients are able to walk shortly after treatment and return home on the same day.

Routine prolonged bed rest is generally not required after most minimally invasive procedures.

8. After treatment and recovery

Post-treatment instructions depend on the method used.

In some patients, compression stockings or an elastic bandage may be recommended for a certain period. Regular walking is often encouraged after treatment.

Depending on the procedure, patients may also be advised to temporarily avoid:

  • Very hot baths
  • Sauna
  • Intense heat exposure
  • Prolonged inactivity
  • Heavy exercise during the early recovery period

Mild bruising, tenderness, tightness, or localized firmness may occur after some procedures and usually improves gradually.

Recovery time varies depending on the treatment method and the extent of the venous disease.

9. Follow-up and control examinations

Follow-up is an important part of the varicose vein treatment process.

Control examinations may be planned according to the treatment performed and the patient’s clinical situation.

During follow-up, the doctor may evaluate:

  • The treated vein
  • Venous blood flow
  • Symptoms
  • Healing of the treatment area
  • Residual varicose veins
  • The need for additional sclerotherapy, laser, or other treatment

Not every patient requires the same follow-up schedule.

10. Preventive measures after treatment

Varicose veins can recur or new veins may develop over time, even after successful treatment of the original problem.

Preventive measures may include:

  • Regular walking and physical activity
  • Avoiding prolonged sitting or standing when possible
  • Weight management
  • Elevating the legs when appropriate
  • Avoiding excessive heat exposure
  • Using compression stockings when medically indicated
  • Attending follow-up appointments when recommended

These measures may help reduce symptoms and support venous circulation.

What should patients pay attention to during the varicose vein treatment process?

A successful varicose vein treatment process depends not only on the procedure itself but also on accurate diagnosis, correct treatment selection, appropriate follow-up, and patient compliance with post-treatment recommendations.

Every patient has a different venous anatomy and a different pattern of venous disease. For this reason, treatment should be planned individually rather than applying the same method to every patient.

At Dr. İlker Zan’s clinic in Antalya, the treatment plan is based on the clinical examination and, when required, detailed color Doppler ultrasound findings.
