          Abstract

          CHIVA (Cure Conservatrice et Hemodynamique de l’Insufficience Veineuse en Ambulatoire) is a type of operation for varicose veins that avoids destroying the saphenous vein and collaterals. We report a case of CHIVA treatment of two saphenous veins to spare these veins. The patient previously had a normal great saphenous vein stripped in error in a wrong-site surgery, while two saphenous veins that did have reflux were not operated. The patient was symptomatic and we performed a CHIVA operation on the left great and right small saphenous veins. The postoperative period was uneventful and both aesthetic and clinical results were satisfactory. This case illustrates that saphenous-sparing procedures can play an important role in treatment of chronic venous insufficiency. Additionally, most safe surgery protocols do not adequately cover varicose veins operations. Routine use of duplex scanning by the surgical team could prevent problems related to the operation site.

          Resumo

          Cure conservatrice et hemodynamique de l’insufficience veineuse en ambulatoire (CHIVA) é um tipo de cirurgia de varizes que evita a destruição da veia safena e colaterais. Este relato apresenta uma paciente que foi submetida a CHIVA em duas safenas para poupá-las. A paciente teve uma safena magna normal retirada em uma cirurgia no sítio cirúrgico errado, as safenas com refluxo foram mantidas, e uma normal foi ressecada. A paciente estava sintomática e foi realizada CHIVA na safena parva direita e na magna esquerda. O pós-operatório transcorreu bem com resultado clínico e estético satisfatório. Esse caso mostra que cirurgias que poupam a safena têm papel importante no tratamento da insuficiência venosa crônica. Além disso, os protocolos de cirurgia segura não cobrem adequadamente as cirurgias de varizes devido a duas safenas possíveis e por serem frequentemente cirurgias bilaterais. A realização de eco-Doppler rotineiramente pela equipe cirúrgica pode prevenir problemas relacionados ao sítio operatório.

          Pathogenesis of varicose veins - lessons from biomechanics

          The development of varicose veins or chronic venous insufficiency is preceded by and associated with the pathophysiological remodelling of the venous wall. Recent work suggests that an increase in venous filling pressure is sufficient to promote varicose remodelling of veins by augmenting wall stress and activating venous endothelial and smooth muscle cells. In line with this, known risk factors such as prolonged standing or an obesity-induced increase in venous filling pressure may contribute to varicosis. This review focuses on biomechanically mediated mechanisms such as an increase in wall stress caused by venous hypertension or alterations in blood flow, which may be involved in the onset of varicose vein development. Finally, possible therapeutic options to counteract or delay the progress of this venous disease are discussed. Eine maladaptive Reorganisation der venösen Gefäßwand geht der Entstehung von varikösen Venen bzw. der Etablierung einer chronischen venösen Insuffizienz voraus, ist aber auch mit deren weiterer Progression assoziiert. Jüngste Arbeiten legen nahe, dass ein Anstieg des Füllungsdrucks durch die resultierende Erhöhung der Wandspannung und die Aktivierung venöser Endothel- und glatter Gefäßmuskelzellen ausreicht, um in Venen variköse Veränderungen zu initiieren. In Übereinstimmung mit dieser Hypothese scheinen bekannte Risikofaktoren wie langes Stehen oder eine durch Übergewicht verursachte Erhöhung des hydrostatischen Drucks die Bildung variköser Venen zu begünstigen. Der vorliegende Übersichtsartikel befasst sich mit verschiedenen biomechanisch induzierten Mechanismen wie etwa eine durch venösen Hochdruck oder Veränderungen im Blutfluss hervorgerufene Erhöhung der Wandspannung, die in der Frühphase der Varizenbildung eine Rolle spielen könnten. Abschließend werden mögliche therapeutische Ansatzpunkte diskutiert, die die Progression dieser venösen Erkrankung verhindern bzw. verzögern könnten.

              CHIVA method for the treatment of chronic venous insufficiency.

              Many surgical approaches are available to treat varicose veins secondary to chronic venous insufficiency. One of the least invasive techniques is the ambulatory conservative hemodynamic correction of venous insufficiency method (cure conservatrice et hémodynamique de l'insuffisance veineuse en ambulatoire (CHIVA)), an approach based on venous hemodynamics with deliberate preservation of the superficial venous system. This is an update of the review first published in 2013.
