Evaluating QoL and Postoperative Complications Using TEThA Technique in the Treatment of Tributary Veins
Sponsor: Nara Medeiros Cunha de Melo Vasconcelos
Summary
Endovenous laser thermoablation is a well-established alternative for the treatment of tributary veins. We believe that it is possible to improve the techniques described in the literature, aiming not only to allocate the laser fiber within the venous lumen, but mainly to transfix the vessel walls - a technique called TEThA (Transfixing Endovenous Thermal Ablation).

TEThA technique
Patient in an orthostatic position, previously marked varicose veins will be punctured with a tracing adjacent to them, surrounding their edges. Applying an augmented reality device and Doppler ultrasound (Doppler USG), the marking will be complemented in the supine position. These punctures will in turn be carried out using the TEThA technique - endovenous thermoablation of tributary veins by means of transfixation - and will be done sequentially as they are treated one by one with endo- and perivenous thermoablation under generous tumescence with 0.08% lidocaine in saline solution. The laser used to treat the tributary veins will also be 1470 nm and will be fired as the fiber is removed at a speed of 1 mm/sec and power ranging from 5 to 7 watts.
