Abstract
Background
Use of endolaser for chronic venous disease involves choosing the laser wavelength and optical fiber to use and the quantity of energy to be administered. Efficacy is assessed by the venous occlusion rate and safety is evaluated in terms of side effects.
Objectives
To determine the incidence of total post-endolaser saphenous vein occlusion at 1-year follow-up. To describe side effects and their incidence and rates of reintervention or supplementary treatment during the postoperative period.
Methods
A retrospective, observational cohort study with a quantitative approach, enrolling patients with saphenous vein incompetence treated with intravenous 1,470 nm laser ablation. Data were input to an MS Excel 2019 spreadsheet, calculating means and standard deviations with the software’s Power Query supplement.
Results
38 patients and 104 venous segments were eligible for the study. 100% were occluded at 30 days and 99.04% were still occluded at 1 year after the procedure. Mean Linear Endovenous Energy Density administered to the internal saphenous vein was 2,040.52 W/cm/s with standard deviation of ± 1,510.06 W/cm/s and 1,168.4 W/cm/s with standard deviation of ± 665.011 W/cm/s was administered to the external saphenous vein. Pain along the saphenous path was the most common side effect, with eight cases (21.05%), followed by one case of paresthesia (2.63%).
Conclusions
The total occlusion rate at 1-year follow-up suggests the technique is promising and is currently applicable in this sample. The incidence of pain and paresthesia may be caused by the high mean energy delivered in some cases. It is recommended that multicenter studies be conducted with larger and more uniform samples in terms of their Clinical-Etiological-Anatomical-Pathological classifications.
