RESUMO
Although ultrasound-guided interventional procedures have resulted in great advances in many fields of medicine, this approach has revolutionized endovascular procedures. This paper aims to review the basic principles to develop a strategy to follow in ultrasound-guided treatments of varices in the lower limbs, as well as to provide a brief overview of the main endovenous techniques available nowadays. We divide these techniques into those that use catheters to occlude straight saphenous axes (thermal / non-thermal ablation) and other options, such as foam sclerotherapy, which can be used in all types of varices, even in those originating in the pelvis.

Si en muchos campos de la medicina el intervencionismo ecográfico ha aportado grandes avances, sin duda en lo que respecta a las terapias endovenosas ha supuesto una revolución. El presente artículo pretende repasar los principios básicos para desarrollar una estrategia a seguir en los tratamientos ecoguiados de varices en los miembros inferiores. Así mismo, busca transmitir una breve perspectiva sobre las principales técnicas endovenosas disponibles en la actualidad. Dichas técnicas las dividiremos principalmente en aquellas que se sirven de un catéter con el fin de ocluir los ejes safenos rectos (ablación térmica/no térmica) y aquellas otras opciones, como es la esclerosis con espuma, que permite su uso en todo tipo de varices, incluso las de origen pélvico.(AU)
