Overview
Endovenous ablation (EVA) is a minimally invasive procedure used to treat varicose veins and chronic venous insufficiency. Instead of traditional vein stripping surgery, this technique uses laser or radiofrequency energy to close abnormal veins, improving blood flow and reducing symptoms.
In South Korea, endovenous ablation is performed in modern vascular and phlebology centers with advanced imaging equipment, ensuring precise treatment, minimal discomfort, and fast recovery. Korea is recognized for its state-of-the-art vascular procedures and highly skilled specialists, making it an excellent choice for patients seeking safe and effective vein treatment.
What is Endovenous Ablation?
Endovenous ablation involves closing diseased veins using heat energy delivered through a catheter inserted via a small puncture in the skin.
This procedure is typically used for:
- Treating varicose veins causing pain, swelling, or discomfort
- Managing chronic venous insufficiency to prevent ulcers or skin changes
- Reducing cosmetic concerns related to visible bulging veins
- Avoiding traditional surgery, offering a less invasive alternative
The procedure uses ultrasound guidance to ensure accurate catheter placement and vein closure.
What are the benefits?
Endovenous ablation offers several advantages:
- Minimally invasive → no large incisions, reduced bleeding and scarring
- ➤ Quick recovery → most patients resume normal activities within a few days
- ➤ High success rate → effectively closes diseased veins and reduces recurrence
- ➤ Pain relief → alleviates leg heaviness, aching, and swelling
- ➤ Improved cosmetic appearance → veins flatten and become less visible
- ➤ Widely available in Korea with advanced laser and radiofrequency technology
Procedure Details
1) How should I prepare for Endovenous Ablation?
Preparation is straightforward but crucial for safety:
- Medical evaluation → blood tests, vein mapping, and duplex ultrasound
- Medication review → anticoagulants or blood-thinning drugs may need adjustment
- Avoid lotions on the legs → ensures clear ultrasound imaging
- Comfortable clothing → easy to wear compression stockings after procedure
- Informed consent → discuss procedure risks, benefits, and recovery plan
2) What happens during the procedure Endovenous Ablation?
The procedure typically takes 30–60 minutes:
- Local anesthesia → the treatment area is numbed; sedation may be used if needed
- Ultrasound guidance → identifies the diseased vein and guides catheter insertion
- Catheter insertion → a thin catheter is inserted into the vein through a small puncture
- Energy delivery → laser or radiofrequency energy heats the vein, causing it to collapse and seal
- Completion → catheter is removed, and compression dressing or stockings are applied
In Korea, the procedure is often combined with foam sclerotherapy or phlebectomy for enhanced cosmetic and therapeutic results.
3) What happens after an Endovenous Ablation?
- Compression → patients wear compression stockings for 1–2 weeks to support healing
- Mild discomfort → bruising, swelling, or tenderness may occur for a few days
- Resume activities → walking is encouraged immediately; strenuous activity may be limited for a week
- Follow-up → ultrasound checks ensure the vein remains closed and blood flow improves
- Cosmetic improvement → visible veins gradually fade over several weeks
Risks / Benefits
Potential Risks:
- Bruising, swelling, or tenderness along the treated vein
- Skin discoloration or temporary nerve irritation
- Rare complications → blood clots, infection, or vein recanalization
Key Benefits:
- Effective relief of varicose vein symptoms
- ➤ Minimally invasive with fast recovery
- ➤ Improved cosmetic appearance
- ➤ Reduced risk of venous ulcers or complications from chronic insufficiency
- ➤ High success rates in Korea using advanced laser and radiofrequency technology
Recovery and Outlook
- Immediate recovery → patients can usually walk and return to daily activities the same day
- Follow-up care → periodic ultrasound ensures treated veins remain closed
- Long-term outcomes → most patients experience lasting relief from symptoms, and treated veins generally do not recur
- In Korea, post-procedure care includes compression guidance, activity recommendations, and optional cosmetic touch-ups to maximize results
When To Call the Doctor
Contact your healthcare provider if you experience:
- Severe leg pain or swelling
- ➤ Signs of infection such as redness, warmth, or discharge
- ➤ Persistent bruising or skin changes
- ➤ Sudden calf pain or shortness of breath (possible blood clot)
- ➤ Any unusual symptoms beyond normal post-procedure discomfort
Prompt evaluation ensures safe recovery and prevents complications.
