Reasons why we prefer CHIVA
- Have as few relapses as possible and have long-term international scientific evidence for it. We live decades after varicose vein operations. Thus, two years of evidence about recurrence is not significative. People with varicose veins are known to have a tendency to relapse. There is also evidence that the elimination of veins creates new veins. CHIVA has 10 years of follow-up in clinical trials compared with the technique of removing the saphenous vein with less recurrence and fewer nerve injuries.
- If possible, preserve the saphenous vein for future use in myocardial revascularization grafts (coronary occlusion and infarction)or limb salvage bridges (if arterial occlusion occurs in the legs).
- Maintains natural leg circulation if relapses, thrombosis or trauma occur in the future. These factors create a need for greater drainage.
- Procedure that can adapt the treatments to the types and anatomical sites of chronic venous insufficiency.
- Preserve the saphenous vein drainage function to decrease collateral recurrences and not stimulate the appearance of vessels.
- Limit the progression of varicose veins in case of a new deep leaking point. (These new leak points are common and there is no way to avoid them until now.)
- The smaller the procedure and the lower the risk, the better. Local anesthesia is important to maintain the overall risk of low complications and decrease the risk of nerve damage in the procedure.
