Ablação térmica total assistida: apresentação da técnica ATTA

Abstract

Abstract Treatment of lower limb chronic venous disease has progressed exponentially over recent decades. The advances achieved have made it possible to develop a proposal for a systematized intravenous laser ablation technique — assisted total thermal ablation (ATTA). The technique constitutes a standardized method for management of axial or tributary veins that are varicosed or esthetically unappealing, whether in the lower limbs or other areas, that can be performed on an outpatient or day-hospital basis. This article describes the processes for preoperative preparation and detailed marking, the materials needed, venous access, anesthesia, calculation of power and energy, the ablation technique itself, follow-up, and adverse events. The ATTA technique is proposed as a tool for treatment of chronic venous disease and of esthetically unappealing veins, suggesting possible extension of the applications for lasers beyond trunk veins to any vein that can be punctured.
