An accurate diagnosis is essential for proper treatment.
What I’ve realized most deeply in my 20 years as a surgeon is this
“When the diagnosis is accurate, the treatment is effective.”
As a surgeon, I know that treating a condition effectively requires first making an accurate diagnosis and then determining the precise extent of excision needed.
At Yonsei DeunDeun Surgery Clinic, we promise to provide only accurate diagnoses and proper treatments, backed by extensive clinical experience
and the latest medical equipment.

Varicose Vein Treatment Process
We provide answers to all your questions
about varicose vein procedures.
Usually, when leg veins appear prominent or bulging, it is considered varicose veins.
However, if it is still in the early stage or if the veins are deep and not easily visible (latent varicose veins), the veins may not be noticeable from the outside.
Even if the veins are not bulging, symptoms such as leg numbness, pain, or abnormal sensations may still occur.
The most accurate way to confirm this is through a vascular Doppler ultrasound, which can easily diagnose whether there is venous reflux.
The minimally invasive, fundamental procedures for varicose veins performed at Yonsei DuenDuen Surgery Clinic—such as laser treatment, radiofrequency ablation, VenaSeal, and mechanochemical ablation (MOCA)—are virtually painless.
You can return to your daily activities immediately after the procedure.
At Yonsei DuenDuen Surgery Clinic, we perform intravascular procedures, which are minimally invasive treatments for varicose veins.
The procedure can be done with just a single needle puncture in the damaged vein.
In the case of laser or radiofrequency treatments, one or two additional needle punctures may be made around the vein for tumescent anesthesia.
These marks typically fade over time and become barely noticeable after the procedure.
Yes. The saphenous vein being treated is diseased and no longer functions properly, so it's okay to remove it.
There are countless veins in the legs.
Among them, the ones that are not functioning well are not necessary.
In fact, removing the refluxing veins that are working in reverse can relieve the burden on the healthy veins.
Sometimes, people leave bulging veins in their legs untreated because they don’t experience any particular symptoms.
However, treatment is strongly recommended.
Varicose veins are a progressive condition that can lead to persistent pain, numbness, and sensory disturbances—far beyond cosmetic concerns.
In more advanced stages, skin ulcers may also develop.
The most serious concern is that if left untreated, varicose veins can lead to life-threatening complications such as deep vein thrombosis.
Varicose veins have a strong genetic tendency.
According to some statistics, if one parent has varicose veins, the likelihood of developing the condition is about 25% for sons and 62% for daughters.
If both parents are affected, the probability for their children rises to over 90%.
Especially if the mother has varicose veins, daughters are at a significantly higher risk of developing the condition.
Venous insufficiency in the legs, which involves reflux, can sometimes improve with medication or medical compression stockings, depending on age and severity.
However, if the veins are visibly bulging and twisted, as in varicose veins, a procedure is often necessary.
We provide treatment in a comfortable and relaxing environment.
At Yonsei Deundeun Surgery Clinic, we are committed to
accurate diagnosis and proper treatment nothing less.
