FAQ for International Patients: Varicose Vein Treatment in Korea

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?

Most adults with symptomatic varicose veins — those causing heaviness, aching, swelling, skin changes, or bleeding — are candidates for treatment. 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?

For most patients, 3–5 days is sufficient: one day for consultation and evaluation, one day for the procedure, and one to two days for post-procedure assessment before return travel. If you have bilateral disease or a complex presentation requiring staged treatment, a longer stay may be recommended.

Is the procedure painful?

Endovenous procedures are performed under local tumescent anesthesia, which involves multiple small injections along the vein to be treated. The injections themselves cause brief stinging; after infiltration, the procedure is typically well-tolerated without significant discomfort. Most patients describe the experience as manageable and are surprised by how minor it is.

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?

Most patients can travel 3–5 days after their procedure. For flights under 4 hours, travel is typically feasible 48–72 hours after treatment with appropriate compression. For longer intercontinental flights, we generally recommend waiting 4–5 days and maintaining graduated compression throughout the flight, with regular in-flight ambulation.

What are the risks of varicose vein treatment?

Modern endovenous procedures have well-established safety profiles. The most common side effects are bruising, tenderness, and a firm cord along the treated vein (phlebitis) — all of which are temporary and typically resolve within 2–4 weeks.

Serious complications are rare. Deep vein thrombosis (DVT) occurs in less than 1% of properly performed endovenous procedures with appropriate anticoagulation protocols. Nerve injury is a low risk with experienced ultrasound-guided technique. Skin burns are essentially eliminated with tumescent anesthesia.

Will my varicose veins come back?

The treated vein will be permanently closed and will not reopen. However, varicose vein disease is a systemic 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).

Long-term recurrence rates are meaningfully lower when the source of reflux is properly 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 — matters for durable outcomes.

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. The standard post-procedure follow-up is a duplex ultrasound at 4–6 weeks to confirm closure of the treated vein. This can be performed by any vascular specialist or vascular laboratory in your home country.

If you have concerns or questions after returning home, we are available via email and video consultation.

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.
