Please Keep This in Mind!

The basic principle behind all varicose vein treatments is the same.

Sun Vascular Clinic is equipped to provide every type of varicose vein treatment.
We do not recommend only one specific method.

There are several ways to treat varicose veins, but the treatment principle remains the same.
An expensive treatment is not always better.
Having advanced equipment or tools does not automatically guarantee better results.

At Sun Vascular Clinic, we do not rely on a single procedure under the label of advanced treatment.
We carefully analyze the location of the refluxing veins, the strength of blood flow, and the patient’s symptoms to select the most appropriate treatment method.

Sun Vascular Clinic performs only treatments whose safety and effectiveness have been verified through published medical research.

* Symptoms may vary and may appear in a mix of early, mid, and late stages depending on the progression of the disease.

Medication / Injection Treatment
Medication Treatment
This treatment is performed when varicose veins are detected at an early stage. It is used to prevent the progression of varicose veins or to relieve symptoms.
Sclerotherapy
This procedure involves injecting medication into the vein to close off the affected vessel. It is a simple treatment suitable for patients whose symptoms are not severe.
Procedures / Surgeries
VenaSeal
(Horizontal Valve Sealing)
VenaSeal is a treatment that injects medical adhesive into the vein to improve symptoms of varicose veins.
In cases of saphenous vein reflux, the junction between the saphenous vein and the deep vein is sealed horizontally and closely to form an angle near zero degrees, preventing recurrence.
Water Tunnel Laser
This treatment closes the vein using high-energy heat of 500-1000°C generated by the laser. It uses a diffused laser for safety, and the surrounding tissue is protected by a water tunnel that minimizes heat damage. The latest 1940 nm laser achieves an excellent closure rate with less thermal energy compared to older models, providing a safer treatment option.
ClariVein
This method uses a rotating-blade catheter to mechanically stimulate the inner wall of the vein, followed by an injection of a sclerosing agent. There is no heat damage or heat-related side effect.
Mild Radiofrequency Treatment
This procedure closes refluxing veins using heat energy of 100-120°C generated at the tip of a radiofrequency catheter. Like the laser method, it applies the water tunnel technique to maximize safety.
Vein Stripping Surgery
This traditional method is performed under local or general anesthesia. It involves making a small incision in the skin, tying off the refluxing vein, and removing it from the body. It may also be performed in combination with laser treatment.
TECHNOLOGY POSSESSION

Advanced Treatment Technology for Complex Varicose Veins (Venous Insufficiency)

The more challenging the case, the more confident we are.

To ensure the most accurate treatment, we have established a state-of-the-art ultrasound examination system on par with those used in university hospitals.
We utilize this advanced equipment extensively, from diagnosis to surgery, for precise and effective treatment.

  • Recurrent Cases

    Varicose veins are a condition with a high recurrence rate. New varicose veins can develop in previously healthy vessels, and veins that were once treated can become affected again. In cases of recurrence, the previously treated area may not have been completely sealed, allowing reflux to occur again. Because of this, a different diagnostic approach is required.

    At Sun Vascular Clinic, we identify the exact cause of recurrence through venography and determine the most effective treatment method. Venography involves injecting a contrast agent into the vein to visualize blood flow. While this allows clear observation of the bloodstream, it can sometimes make surgery difficult due to vascular constriction. With extensive surgical experience and expertise, the medical team at Sun Vascular Clinic performs accurate examinations without the limitations of conventional venography, ensuring that surgery is carried out safely and effectively.

  • Patients with High Vascular Constriction

    In a relaxed state, veins are dilated and reflux can be severe. However, in tense situations, the veins constrict, and reflux may appear less pronounced. Because the examination is performed while the veins are constricted due to tension, there is a higher chance of false-negative results, making varicose veins more difficult to detect. Since vascular constriction is caused by tension, the most important factor during testing is helping the patient relax.

    At Sun Vascular Clinic, we allow enough time for patients to relax before the examination so that the test can be performed in a calm and comfortable state. During the examination, every vein is carefully examined to determine the most suitable treatment for each patient.

  • Patients Who Have Left the Condition Untreated for a Long Time

    When varicose veins are left untreated, reflux not only worsens but the veins also become deformed. Over time, the veins narrow and become twisted, often resembling a cluster of grape vines. As the veins narrow and become more complex due to neglect, surgery using a catheter can no longer be performed.

    In treatments such as laser or VenaSeal, a catheter is inserted into the vein. However, for patients who have left the condition untreated for a long time, the veins may have become too twisted, stretched, or thinned to allow catheter insertion, limiting available treatment options. At Sun Vascular Clinic, we offer a variety of treatment methods beyond laser and VenaSeal, allowing us to treat such cases using alternative approaches. With over 20 years of experience focused solely on vascular care, our medical team provides one-on-one consultations and delivers the most suitable treatment for each patient, even when options are limited.
