Patients considering varicose vein treatment in Korea typically have a consistent set of questions. This page addresses the most common ones directly, with the goal of providing accurate, clinically grounded answers rather than marketing language.

Am I a candidate for varicose vein treatment?

Adults with symptomatic varicose veins — those causing heaviness, aching, swelling, skin changes, or bleeding — may be candidates for treatment, depending on what the examination shows. Purely cosmetic varicosities (thread veins/spider veins with no hemodynamic reflux) may or may not benefit from intervention depending on their extent and nature.

The definitive assessment of candidacy requires a standing duplex ultrasound study to map the reflux pattern. Without this, it is not possible to determine whether treatment is indicated or what the appropriate approach would be. We can conduct this assessment during your first clinic visit.

Do I need to send anything before I arrive?

A pre-travel consultation is helpful but not mandatory. If you have previous duplex ultrasound reports or medical records from prior vascular evaluations, please bring them or send them in advance. Photographs of visible varicosities are also useful for preliminary assessment. However, even without prior documentation, a complete evaluation can be performed at your first visit.

How long do I need to stay in Seoul?

How long you need to stay is advised after an individual assessment and depends on the examination findings and the treatment performed; we do not promise a fixed short stay. If you have bilateral disease or a complex presentation requiring staged treatment, a longer stay may be recommended.

Is the procedure painful?

Thermal ablation is performed under local tumescent anesthesia, which involves multiple small injections along the vein to be treated; non-thermal methods such as adhesive closure do not use tumescent anesthesia. Where tumescent anesthesia is used, the injections themselves cause brief stinging; after infiltration, the procedure is usually tolerated without much discomfort, although how it feels varies from person to person.

Post-procedure discomfort is generally mild — bruising, some tightness, and occasional tenderness along the treated vein for 1–2 weeks. Over-the-counter analgesics are usually sufficient for pain management.

How quickly can I travel home after treatment?

The timing of return travel is decided at the post-procedure check, according to the treatment performed, your clot risk factors and the flight duration. For longer intercontinental flights, we generally recommend maintaining graduated compression throughout the flight, with regular in-flight ambulation.

What are the risks of varicose vein treatment?

The side effects of modern endovenous procedures are well documented. The most common are bruising, tenderness, and a firm cord along the treated vein (phlebitis), which usually settle within 2–4 weeks.

Serious complications are uncommon but can occur. They include deep vein thrombosis (DVT), nerve injury and, with thermal techniques, skin burns; ultrasound guidance and tumescent anesthesia are used to reduce these risks.

Will my varicose veins come back?

The treated vein usually stays closed, but closure cannot be guaranteed in every case. In addition, varicose vein disease is a chronic condition: new varicosities can develop in other vein segments over time, particularly in patients with strong genetic predisposition, significant risk factors, or ongoing hormonal influences (e.g., multiple pregnancies).

Recurrence is generally considered less likely when the source of reflux is identified and treated, rather than simply removing visible varicosities. This is why comprehensive duplex mapping and treatment of the hemodynamic source — not just surface branches — are part of treatment planning.

How do I arrange follow-up when I return home?

We provide complete procedure documentation in English, including the technique used, vein segments treated, and recommended follow-up. Follow-up ultrasound is part of our care for every treated patient. For patients returning home, the schedule is agreed before you leave, and the scans can be performed by a vascular specialist or vascular laboratory in your home country.

If you have concerns or questions after returning home, you can reach us through the clinic's consultation channels (WhatsApp, or One-Talkie, our chat with built-in interpretation).

How do I contact the clinic and start the process?

International patient inquiries can be submitted through our clinic website. We respond to all inquiries and aim to provide a preliminary response within 1–2 business days.
