CHIVA to treat saphenous vein insufficiency in chronic venous disease: characteristics and results

Abstract There is considerable debate in the literature with relation to the best method to treat patients with chronic venous disease (CVD). CHIVA is an office-based treatment for varicose veins performed under local anesthesia. The aim of the technique is to lower transmural pressure in the superficial venous system and avoid destruction of veins. Recurrence of varicosities, nerve damage, bruising and suboptimal aesthetic results are common to all treatments for the disease. This paper evaluates and discusses the characteristics and results of the CHIVA technique. We conclude that CHIVA is a viable alternative to common procedures that is associated with less bruising, nerve damage, and recurrence than stripping saphenectomy. The main advantages are preservation of the saphenous vein, local anesthesia, low recurrence rates, low cost, low pain, and no nerve damage. The major disadvantages are the learning curve and the need to train the team in venous hemodynamics.Resumo Existe uma grande discuss ão na literatura sobre o tratamento da doença venosa crônica (DVC). A cura conservadora e hemodinâmica da insuficiência venosa em ambulatório (CHIVA) consiste no tratamento ambulatorial de varizes sob anestesia local. O objetivo da técnica é diminuir a pressão transmural no sistema venoso s uperficial para evitar a destruição das veias, incluindo as veias safenas. Recorrência de varizes, lesão de nervos, hematomas e resultado estético abaixo do ideal são uma constan...
