Short Answer
Modern varicose vein treatment methods are planned according to the type of varicose vein and the results of the Doppler Ultrasound; today, many patients can receive non-surgical varicose vein treatment options (endovenous laser ablation, radiofrequency, sclerotherapy foam treatment, medical adhesive) under local anesthesia, without incisions or stitches, and patients often return home walking on the same day.
Varicose veins are a progressive circulatory system problem that can manifest with pain, swelling, a feeling of heaviness in the legs, nighttime cramps, and aesthetically disturbing vein appearances. Although often perceived as merely a “cosmetic” issue, if left untreated, it can lead to serious consequences such as permanent edema in the legs, skin color changes, hard-to-heal wounds (venous ulcers), and thrombosis (thrombophlebitis).
In the past, classical surgeries could be challenging for patients due to large incisions and longer recovery times. However, with advancements in medical technology, varicose vein treatment methods have largely evolved into comfortable, incision-free, and fast recovery-focused options. Our team at Istanbul Private Family Hospital’s Vascular Surgery aims to personalize current approaches from endovenous methods to capillary vein treatment according to the stage of varicose veins.
What causes varicose veins and why should they be treated?
Varicose veins occur due to the malfunction of unidirectional valves in the leg veins, causing blood to flow backward (pooling) and increasing pressure within the vein. This increased pressure leads to the dilation of veins, making them tortuous, and eventually transforming into visible varicose vein clusters.
How do venous valves work?
Veins carry “dirty blood” against gravity towards the heart; the structure that facilitates this is the unidirectional valves within the veins. When these valves malfunction, blood flows backward, and complaints become more pronounced, especially when standing.
What causes varicose veins? (What are the risk factors?)
The answer to what causes varicose veins often relies on multiple factors. The most common risk factors are:
- Genetic predisposition (family history)
- Prolonged standing (such as teaching, hairdressing, retail)
- Sedentary lifestyle and prolonged sitting
- Pregnancy (hormonal effects and increased abdominal pressure)
- Obesity
- Weakening of vein walls and valves with age
What happens if left untreated?
Untreated varicose veins can progress over time and lead to the following conditions:
- Significant edema and pain in the legs
- Skin color changes, itching, and eczema-like symptoms
- Venous ulcers (leg wounds)
- Thrombophlebitis (clotting and inflammation in superficial veins)
Therefore, the goal is not only to correct the aesthetic appearance but also to control the underlying venous insufficiency with the appropriate method.
Which varicose vein treatment methods are preferred for which type of varicose veins?
The correct method selection is based not on the “appearance” of the varicose vein but on the type of varicose vein and the presence of reflux (backward flow) detected by standing Venous Color Doppler Ultrasound. This approach increases the success of the treatment and prevents unnecessary procedures.
How are types of varicose veins classified?
Varicose veins are practically considered in three main groups:
- Capillary veins (spider vein appearance): Red-purple fine lines under the skin.
- Medium-sized varicose veins: More pronounced, superficial, tortuous veins.
- Major/primary vein insufficiency (internal varicose veins): Conditions that may require more extensive treatment due to reflux in the main veins.
Short decision logic (Doppler-focused)
The following table summarizes the general decision flow; the definitive plan is clarified through examination and Doppler for each patient:
| Varicose vein type / Doppler finding | Frequently preferred approach | Note |
|---|---|---|
| Capillary veins (very thin) | Transdermal laser/RF or sclerotherapy in selected cases | Surface methods are preferred for veins too thin to be accessed with a needle. |
| Medium-sized varicose veins | Sclerotherapy and foam treatment (foam sclerotherapy) | Can be applied in outpatient settings. |
| Major vein insufficiency (reflux) | Endovenous laser ablation (EVLA) or radiofrequency ablation (EVRF) | Can be applied under local anesthesia, without incisions or stitches. |
| Very bulging, clustered varicose veins | Microphlebectomy (mini incisions) + ablation/foam combination | Usually planned in combination; aesthetic scarring is minimal. |
| Selected cases where closure without heat is desired | Liquid embolization (medical adhesive) | Emphasizes the advantage of no risk of nerve damage due to the absence of thermal energy. |
This framework demonstrates that the idea of “one method fits all” is incorrect. Varicose vein treatment often yields better results with a combination approach.
Why is standing Doppler ultrasound essential and how does it determine the treatment plan?
Standing Doppler ultrasound is fundamental to planning because it provides the clearest answer to the question, “which vein has reflux?” When the patient is standing, the effects of gravity allow for a more realistic assessment of the intra-venous flow dynamics, and hidden refluxes can be detected more accurately.
What does “hidden reflux” mean?
Reflux is the backward flow of blood in the vein; this condition can be the source of varicose veins. The visible varicose vein twists may sometimes be the “result”; the actual problem may be reflux in the main vein. Therefore, it is necessary to identify the source rather than just targeting the visible vein.
What information is evaluated based on the Doppler result?
A vascular surgeon generally looks at the following during the Doppler examination:
- The location and severity of the reflux
- Whether the insufficiency is in the main vein or a branch
- Vein diameters and the relationship between superficial/deep systems
- The need for a planned combination after treatment (e.g., EVLA + microphlebectomy)
Practical preparation tips for the examination
- Note your complaints: at what times of the day do they increase, is there swelling/cramping?
- If you have previously undergone varicose vein treatment, share the method and date.
- Inform your doctor about any medications you regularly take (especially blood thinners).
These steps help plan the non-surgical varicose vein treatment options in the most appropriate order for you.
What are the non-surgical varicose vein treatment methods and how are they applied?
Non-surgical varicose vein treatment refers to modern techniques applied under local anesthesia, without incisions or stitches, in most patients. The choice of method is determined based on the type of varicose vein, Doppler findings, and clinical examination.
What is endovenous laser ablation (EVLA)?
Endovenous laser ablation (EVLA) is a method used for major and primary vein insufficiencies (internal varicose veins), where a thin catheter is inserted into the vein under ultrasound guidance, and laser energy is used to heat and close the vein from the inside. The procedure is performed in an operating room setting, but without general anesthesia, using local tumescent anesthesia; there are no incisions or stitches, and the patient can walk after the procedure.
Key features of EVLA:
- Ultrasound-guided, targeted application
- Incision-free and stitch-free approach
- Mobilization on the same day (returning to daily life walking)
What is radiofrequency ablation (EVRF)?
Radiofrequency ablation (EVRF) is logically similar to EVLA; the difference is that instead of laser light, heat energy generated by radiofrequency waves is used to close the vein. It is considered a safe option, aiming for a low rate of bruising and rapid recovery.
How is sclerotherapy and foam sclerotherapy performed?
Sclerotherapy is a commonly used method for medium-sized varicose veins and prominent capillary veins; medication is injected into the vein using very fine needles, aiming for the vein walls to stick together. The application made by mixing the medication with air to create foam is referred to as foam sclerotherapy. The foam form can provide the advantage of penetrating larger veins with a lower dose of medication and can be applied in outpatient settings.
Practical expectations after sclerotherapy/foam treatment:
- The number of sessions may vary depending on the vein structure
- Short-term sensitivity or color changes may be observed
- The walking and follow-up plan recommended by the doctor is important
What is liquid embolization (medical adhesive/bioadhesive)?
Liquid embolization involves injecting a tissue-friendly special medical adhesive into the vein, aiming for the vein to adhere and close immediately. The prominent advantage of this method is that there is no risk of nerve damage because no heat energy is used, and generally, there is no obligation to wear compression stockings after the procedure.
What is capillary vein treatment (transdermal laser and radiofrequency)?
Capillary vein treatment involves treating very fine red/purple veins (spider vein appearance) just beneath the skin. In veins too thin to be accessed with a needle, transdermal laser and/or surface radiofrequency applications aim to destroy the veins; aesthetically pleasing results are sought.
When is microphlebectomy (mini surgical incisions) necessary?
Microphlebectomy is the procedure of removing visibly bulging, clustered large varicose vein twists through small 1-2 mm openings in the skin using special instruments. It aims not to require stitches and to leave minimal aesthetic scarring; it is often combined with endovenous methods.
What to expect in the post-treatment process for varicose veins?
The post-treatment process varies depending on the method applied, but in most modern approaches, the goal is for the patient to be able to walk on the same day and quickly return to daily life. Post-procedure recommendations help enhance the effectiveness of the treatment and increase comfort.
Why is walking on the same day recommended?
Walking supports venous circulation by activating the leg muscle pump; therefore, doctors often recommend controlled walking after the procedure. The duration and pace of walking are personalized according to the patient’s general condition and the procedure performed.
Is compression stocking necessary for every patient?
The need for compression stockings varies according to the treatment method and the doctor’s plan. While they may be recommended for certain periods after some endovenous procedures or sclerotherapy that use heat energy, the medical adhesive method is generally expressed as an advantage due to the lack of necessity for stockings.
Does recurrence (reappearance) occur?
The answer to whether varicose veins recur depends on factors such as genetic predisposition and lifestyle. Treating the correct vein with the correct method and regular follow-up with Doppler can help reduce the risk of recurrence; additionally, new vein formations may appear over time in different areas.
What should be considered in daily life?
The following recommendations provide a general framework for most patients (your doctor will determine the personal plan):
- Avoid prolonged standing in one position, take short walking breaks
- Perform leg exercises during long sedentary journeys
- Maintain weight control and regular activity
- Do not miss follow-up appointments
At Istanbul Private Family Hospital’s vascular surgery unit in Istanbul, the aim is to accurately diagnose using standing Doppler and combine options such as EVLA, EVRF, foam treatment, adhesive, and when necessary, microphlebectomy into a single plan suitable for the stage of varicose veins.

Frequently Asked Questions
Who is non-surgical varicose vein treatment suitable for?
Non-surgical varicose vein treatment is a suitable option for many patients based on the type of varicose vein and standing Doppler ultrasound findings. Endovenous laser ablation or radiofrequency for major vein insufficiency; foam sclerotherapy for medium-sized varicose veins; transdermal laser/RF for capillary vein treatment may be preferred. The most accurate decision is made through examination and Doppler.
Is endovenous laser ablation (EVLA) painful?
Endovenous laser ablation is generally performed under local tumescent anesthesia, aiming for pain control during the procedure. There may be short-term sensitivity or a feeling of tightness afterward; follow-up and recommendations are personalized. The most important point is that the application is made to the correct vein under ultrasound guidance.
Which is better, EVLA or radiofrequency ablation?
EVLA and radiofrequency ablation are modern methods aimed at closing the vein from the inside with a similar logic for major vein insufficiency. Which one is suitable is determined by vein structure, Doppler findings, and the doctor’s clinical assessment. Both methods can be applied with the goals of being incision-free, stitch-free, and quick recovery.
How many sessions does foam sclerotherapy take?
The number of sessions for foam sclerotherapy may vary depending on the diameter of the vein, its extent, and the condition of the subcutaneous vein network. While a single session may be sufficient for some patients, multiple sessions may be planned in some cases. Session intervals and follow-up should be determined by the doctor.
For capillary vein treatment, is laser or needle treatment preferred?
Capillary vein treatment can be planned with transdermal laser/RF or sclerotherapy depending on the thickness and extent of the vein. Surface laser applications are preferred for “spider web” veins that are too thin to be accessed with a needle. Standing Doppler and examination are required for the most accurate method selection.
