CHIVA is the French acronym for “Cure conservatrice et Hemodynamique de l’Insuffisance Veineuse en Ambulatoire” (Conservative and Hemodynamic treatment of Venous Insufficiency in the Office). It is a venous conservative therapeutic approach to varicose veins.

The rationale behind this hemodynamic approach to treating the disease is that increased transmural pressure (TMP) is responsible for the progression of the signs and symptoms of varicose veins, such as varicosities, edema, pain, itching, dermatitis, and ulcers.

The CHIVA procedure aims to reduce the pressure by performing 2 or 3 tiny incisions on the skin and ligate the escape point (PE), without destroying the vein drainage network. Daily activities were not affected after treatment, and varicose veins gradually contracted by themselves after 3 months.
