Taxa de oclusão em safenas pós endolaser 1470 nm e efeitos colaterais no seguimento de 1 ano

Abstract

Background: Nowadays endovenous laser ablation is considered to be the preferred method for the treatment of chronic venous insufficiency and its procedure has been object of discussion about the rate of occlusion and the side effects produced after the operation, mainly in the variables of wave-length, fiber type, energy spent and technique applied. Objectives: To analyze the occlusion rate of the saphenous veins and the side effects post endolaser in the following year, in addition to the need of reintervention for the therapy. Methods: Retrospective cohort analytical survey with quantitative approach of chronic venous insufficient patients treated with endovenous ablation laser 1470 nm from March 2018, to October 2019. All data was registered in MS Excel 2019 with statistics about averages and standard deviation calculated by Power Querry, supplement from the same software. Results: Were eligible to the study 38 patients and 104 venous segments, of which 100 % and 99.04 % were occluded within 30 days and 1 year respectively. The average linear endovenous energy density (LEED) for the great saphenous was 2040.52 w/cm/s with standard deviation 1510.06 w/cm/s, whereas for the small saphenous 1168.4 w/cm/s and 665,011 w/cm/s correspondingly. Pain in the saphenous veins was the most common side effect, accounting for 8 cases (21.05 %), succeed by paresthesia with 1 appearance (2.63 %). Conclusions: The large occlusion rate indicates the efficiency of the method in the 1st year following. The prevalence of post-operative pain may be due to the high energy dissipated in the procedures
