ClariVein is a newly introduced procedure to the United States for the treatment of varicose veins. ClariVein uses mechanical chemical ablation to seal the incompetent vein closed. A very small entry location is accessed with local anesthesia and a very thin, flexible, wire-type catheter is introduced into the vein itself. The tiny, hollow wire is operated by the physician and disturbs the lining of the vein while delivering a sclerosant solution to scar the vein walls closed.
ClariVein is unlike Radiofrequency (RF) or Endovenous laser ablation (EVLA) because it doesn't require heat. Since there is no heat or high temperatures involved, there is no need for tumescent anesthesia.Aside from the initial local injection, the procedure is pain free.
Advantages to ClariVein:
Only micro-incision required - no large cuts or stitches
Reduced risk to surrounding tissue including nerves and other veins
Less bruising compared to some other procedures
Short treatment time
Contraindications to ClariVein:
Patients with history of deep vein thrombosis (DVT)
Allergy to the sclerosing chemical
