C.H.I.V.A: NON DESTRUCTIVE TREATMENT OF VARICOSE VEINS

TRADITIONAL TREATMENTS AND THEIR DISANDVANTAGES

The traditional treatment for varicose veins has been surgical removal (stripping) or chemical destruction (sclerotherapy). More recent methods involve laser and radiofrequency (VNUS Closure Procedure), which are also destructive treatments. One of the problems with this is that the trouble is simply shifted onto other veins that will later become overloaded and unable to function normally. The documented failure rate for surgery is 30 to 80% in one to five years.

The other main problem with destructive treatment is the loss of precious material for life saving purposes. In fact, saphenous veins are the best material for coronary or limbs by-pass.

Destructive techniques, by suppressing the main veins, also suppress venous blood drainage from superficial to deep veins: the risk of varicose vein recurrence is high by the progressive enlargement of collateral veins which replace and overtake the destroyed veins.

Destructive procedures are quite uncomfortable and certainly require a general anaesthesia. They are often performed as a day case but some patients who are having more extensive surgery may require admission overnight. There can be quite extensive bruising which may take some weeks to settle. Patients usually require 2-4 weeks off work to recover. Stripping increases the risk of lymphatic lesions and nerve damage.

With C.H.I.V.A we are now capable of treating patients in an almost non traumatic manner with an extremely selective surgical procedure that preserves the saphenous trunks by relieving them of hemodynamic overload.

C.H.I.V.A depends strongly on an extensive and sophisticated duplex examination by an experienced investigator.

Interpretation of venous hemodynamics using ultrasound signals is a major achievement which allows pre-operative mapping. This means that the surgical plan will vary from case to case and that the treatment is personalized and not standardized.
