Abstract
BackgroundIt is relevant to elucidate the influence that mean linear endovenous energy density (LEED) has on the success of endovenous laser ablation treatment for chronic venous insufficiency, in order to reduce the method’s adverse effects.ObjectivesTo evaluate the influence of mean LEED on the prevalence of saphenous closure 30 days after the laser ablation procedure.Methods153 lower limbs from 118 patients seen at a tertiary hospital and treated for chronic venous insufficiency with endovenous 1470 nm laser ablation under local anesthesia were evaluated. The mean LEED used to treat patients was calculated to determine whether greater than average LEED was required for treatment success.ResultsA significant difference (p = 0.021) in saphenofemoral junction closure was associated with mean LEED used above the knee. Conversely, there was no significant difference in the thigh segment.ConclusionsLinear intravenous energy density greater than the mean of 70.57 J/cm was associated with a higher rate of closure at the saphenofemoral junction. However, density did not have an influence on the result for the thigh segment, showing that an energy density exceeding 70.57 J/cm tends not to be required for treatment of this segment.
Highlights
Chronic venous insufficiency (CVI) is a common disease in the vascular surgeon’s office, affecting 25 to 33% of women and 10 to 20% of men in the adult Western population.[1]
The inclusion criteria were patients with CVI treated with EVLA from the saphenofemoral junction (SFJ) to the knee at the Hospital Angelina Caron from 2011 to February of 2018
A total of 153 lower limbs were analyzed from 118 patients who had been treated with EVLA for CVI
