Vein surgery

Vein surgery has been known since Ancient Rome. It is based on sick vein removal so that they don't damage healthy veins. Until the beginning of this millennium sick veins were removed through incisions in the skin using a special metal or plastic probe. However, it is a traumatic method.

VNUS radiofrequency venous ablation method was introduced in 1998. It was the first method which completely changed the principles of modern vein surgery. The method does not involve removal of sick vein section; it is based on vein closure using heat produced by radiofrequency catheter introduced into the vein from a needle prick. Based on this principle, endovenous laser surgery (EVLT) was introduced in 2001 and endovenous steam microimpulse venous ablation (Cerma SVS) was introduced in 2008. All these methods are not traumatic and are performed using only local anaesthesia; a patient can go home right after the surgery, and go back to his/her daily activities on the following day.

Recommendatins for patients:

1. Please check if the physician in the clinic has all treatment methods at his disposal!

  • Vein closure using VenaSeal™ Closure System (clinics using this method see here>> )
  • Steam microimpulse method (clinics using this method see here>> )
  • Radiofrequency surgery
  • Laser surgery
  • Classic vein surgeries

The surgeon will choose the most appropriate method, not the only one available.

2. Make sure that the price given by the clinic includes all expenses:

  • Cost of the surgery
  • Anaesthesia
  • Cost of the materials
  • Stay in the clinic
  • Cost of the consultation before and after the surgery
  • Compression stockings (there are some surgical methods that do not require wearing compression stockings afterwards)

There are clinics that include all these expenses in one price; other clinics inform about them after the surgery.

3. If you are offered to participate in surgeries which are performed within the framework of clinical studies, YOU MUST KNOW that clinical studies are free of charge in Latvia and in the European Union, or the organiser pays to participants for their participation in this study. A patient must by no means pay for such studies. All legal clinical studies must be registered in the State Agency of Medicines
