What Are Varicose Veins?
Varicose veins are enlarged, twisted blood vessels that form just beneath the skin most commonly in the legs and feet. They develop when the one-way valves inside your veins stop working properly, allowing blood to pool rather than flow smoothly back to the heart. This pooling increases venous pressure, causing the vessel walls to stretch and bulge outward.
They’re easy to recognise: bluish-purple, rope-like cords that may appear raised or knotted under the skin. But unlike purely cosmetic concerns, varicose veins represent genuine circulatory dysfunction that, if left untreated, can progress to chronic pain, skin damage, and in some cases, dangerous blood clots.
Important Distinction
Varicose veins are not the same as spider veins. Spider veins (or thread veins) are tiny, web-like capillaries visible through the skin — usually harmless and purely aesthetic. Varicose veins are deeper, larger, and carry a greater risk of medical complications.
Types of Varicose Veins
Not all varicose veins look the same or carry the same risk. There are four main types:
- Spider veins — Fine, red-blue capillaries on the skin surface; cosmetic only, rarely symptomatic.
- Reticular veins — Slightly larger, blue-green veins close to the surface; may cause mild aching or itching.
- Saphenous (great/small) vein varicosities — The most common clinical type; dilated main leg veins causing heaviness, pain, and swelling.
- Deep vein varicosities — Invisible on the skin surface but detectable by ultrasound; highest risk for DVT and serious complications.
What Causes Varicose Veins?
The root cause is always the same: faulty venous valves. But why those valves fail varies from person to person. Several overlapping risk factors are well established by research:
- Genetics — The single strongest predictor. If both parents have varicose veins, your lifetime risk is approximately 90%.
- Female Sex — Female hormones (oestrogen, progesterone) relax vein walls. Pregnancy and menopause intensify this effect.
- Pregnancy — Increased blood volume plus uterine pressure on pelvic veins dramatically raises risk — often improving after birth.
- Ageing — Vein walls and valves weaken naturally with age. Prevalence rises sharply after 50.
- Obesity — Excess body weight increases intra-abdominal pressure, compressing pelvic veins and impeding blood return.
- Prolonged Standing — Teachers, healthcare workers, hairdressers, and retail workers face elevated risk due to sustained upright posture.
- Sedentary Lifestyle — The leg-muscle “pump” is essential for venous return. Inactivity weakens this mechanism.
- Prior DVT — Previous deep vein thrombosis damages valves permanently, significantly raising varicose vein risk.
Recognising the Symptoms
Varicose veins announce themselves in layers. For some people the first sign is purely visual — a bulging, discoloured vein on the back of the calf. For others, discomfort comes first, long before anything is visible on the skin surface.
- Aching or heavy sensation in the legs
- Burning or throbbing along vein lines
- Muscle cramps, especially at night
- Swelling in ankles and lower legs
- Itching around one or more veins
- Skin discolouration (brownish staining)
- Pain that worsens after prolonged standing
- Restless legs syndrome
- Visible twisted, bulging veins
- Skin hardening above the ankle
Seek Urgent Care If:
A varicose vein begins to bleed, even if the bleeding appears to stop on its own. Varicose vein haemorrhage can be significant. Similarly, sudden-onset calf pain, redness, and warmth may indicate deep vein thrombosis (DVT) — a medical emergency. Contact your doctor or emergency services immediately.
How Varicose Veins Are Diagnosed
Accurate diagnosis goes beyond looking at the skin. A thorough assessment ensures your treatment plan targets the actual source of reflux — not just the veins that are visible on the surface.
Clinical Examination Your specialist will examine your legs while you’re standing (to maximise venous distension), assess skin changes, check capillary refill, and take a detailed history including family history, duration of symptoms, and any prior treatments.
Duplex Doppler Ultrasound The gold-standard investigation. This painless, real-time scan maps your entire venous system — both superficial and deep. It detects valve reflux (blood flowing backwards), measures vein diameter, identifies thrombosis, and guides the choice of treatment. Without it, treatment is essentially guesswork.
Venography (if required) Contrast-enhanced imaging used in complex or recurrent cases where deep vein anatomy must be precisely mapped before surgery. Rarely needed as a first-line test.
Treatment Planning Based on clinical findings and ultrasound mapping, your specialist designs a personalised treatment plan specifying which veins to treat, in which order, and which modality is best suited to each segment.
Varicose Vein Treatment
Modern vascular medicine offers several highly effective, minimally invasive options. The right choice depends on the size and location of the affected veins, your overall health, and the ultrasound findings. Most procedures are performed as outpatient treatments — you go home the same day.
Varicose Vein Treatment in Turkey and Istanbul
Turkey has become one of the leading destinations in Europe and the Middle East for vascular surgery and varicose vein treatment. A combination of internationally trained specialists, modern hospital infrastructure, and significantly lower procedure costs compared to Western Europe or the United States has made Turkey — and Istanbul in particular — an increasingly popular choice for both domestic and international patients.
Why Choose Turkey for Varicose Vein Treatment?
Internationally Accredited Hospitals Many hospitals and private clinics in Istanbul and other major Turkish cities hold JCI (Joint Commission International) accreditation — the global benchmark for healthcare quality. Facilities are equipped with advanced vascular imaging systems, including colour Doppler ultrasound, and offer the full spectrum of minimally invasive treatments such as endovenous radiofrequency ablation, laser ablation, foam sclerotherapy, and medical adhesive (glue) procedures.
Experienced Vascular Surgeons Turkish cardiovascular and vascular surgeons frequently receive postgraduate training in Europe or the United States and maintain active memberships in international phlebology and vascular surgery associations. Many specialists operate in both public university hospitals and private practice, ensuring high clinical standards across settings.
Cost-Effective Care The cost of varicose vein treatment in Turkey is typically 50–70% lower than comparable procedures in the United Kingdom, Germany, or the United States — without compromise in clinical outcome. This cost advantage is particularly significant for procedures such as endovenous laser ablation or radiofrequency ablation, which carry high price tags in many Western healthcare systems.
Accessible Location Istanbul’s two international airports — Istanbul Airport (IST) and Sabiha Gökçen (SAW) — offer direct connections to hundreds of destinations across Europe, the Middle East, Central Asia, and Africa. Most varicose vein procedures require only a short hospital stay or are performed on an outpatient basis, making Istanbul well-suited for medical travel.
Treatment Options Available in Turkey
The full range of evidence-based varicose vein treatments used in leading international centres is available in Turkey:
- Endovenous Radiofrequency Ablation (RFA) — A catheter delivers radiofrequency energy to collapse and seal the diseased vein. No general anaesthesia required; patients walk out the same day.
- Endovenous Laser Ablation (EVLA/EVLT) — Laser energy is delivered via a thin fibre inside the vein. Highly effective for great saphenous vein incompetence.
- Foam Sclerotherapy — Microfoam is injected under ultrasound guidance to close varicose tributaries. Particularly useful for recurrent or complex cases.
- Medical Adhesive (Glue) Method — A medical-grade cyanoacrylate adhesive is injected to seal the vein. No tumescent anaesthesia required, minimal bruising, and a very rapid return to activity.
- Ambulatory Phlebectomy — Superficial varicose tributaries removed through micro-incisions under local anaesthesia.
- Classical Surgery (High Ligation and Stripping) — Still performed in appropriate cases, particularly where minimally invasive options are unsuitable.
What to Expect: The Treatment Process
A typical varicose vein treatment journey in Turkey follows a structured pathway. An initial consultation — which can often be conducted online for international patients — is followed by a duplex Doppler ultrasound examination to map the venous system precisely. Based on these findings, the surgeon designs a personalised treatment plan.
Most minimally invasive procedures are completed in a single session lasting 30–90 minutes. Patients are advised to walk immediately after treatment and can usually return to light daily activities within 24–48 hours. A follow-up ultrasound is typically scheduled one to two weeks post-procedure to confirm successful vein closure.
Istanbul as a Treatment Destination
Istanbul hosts a high concentration of specialist vascular clinics and hospital departments offering varicose vein treatment. The city’s private hospitals and outpatient vascular centres serve both Turkish patients and a growing number of international visitors.
For patients travelling from abroad, the combination of a short procedure, rapid recovery, and the opportunity to recuperate in one of the world’s most culturally rich cities makes Istanbul a particularly compelling option.
Choosing the Right Specialist
When selecting a vascular surgeon or phlebologist in Turkey, patients should look for the following:
- Board certification in cardiovascular surgery, vascular surgery, or a recognised phlebology qualification.
- Routine use of duplex Doppler ultrasound for pre-treatment mapping and post-treatment follow-up.
- Availability of multiple treatment modalities — not a “one-size-fits-all” approach.
- Transparent communication about expected outcomes, potential complications, and aftercare requirements.
- Accredited hospital or clinic affiliation.
As with any medical procedure, thorough research and a detailed pre-treatment consultation are essential steps before committing to treatment.
Can varicose veins go away on their own?
Genuine varicose veins do not resolve spontaneously — once vein valves are damaged, they do not self-repair. However, varicose veins that develop during pregnancy often improve significantly or disappear entirely within 3–6 months after delivery, as the hormonal environment normalises and uterine pressure on the pelvic veins is relieved.
What happens if varicose veins are left untreated?
Many patients live with varicose veins for years without serious complications. However, untreated venous disease tends to progress. Possible complications include chronic leg ulcers (venous ulcers are the leading cause of chronic wound care in adults), haemorrhage, lipodermatosclerosis (hardening of the skin and fat around the ankle), superficial thrombophlebitis, and in some cases, deep vein thrombosis. Early treatment prevents these outcomes and is considerably simpler than managing advanced disease.
Is varicose vein treatment painful?
Modern minimally invasive treatments are well-tolerated. Endovenous ablation uses tumescent local anaesthesia — a dilute solution injected around the vein — which numbs the area effectively and also acts as a heat buffer. Patients typically describe mild pressure or warmth rather than pain. Post-procedure soreness, similar to a muscle bruise, is common for 5–10 days and well-controlled with simple analgesics.
Will varicose veins come back after treatment?
Treated veins do not return — once a vein is ablated or removed, it’s gone. However, new varicosities can develop over time because the underlying tendency towards valve incompetence often remains. Recurrence rates at 5 years are approximately 20–30% depending on the treatment modality and individual risk factors. Regular follow-up and continued adherence to lifestyle measures reduce this risk.
