Favorable long-term results of endovenous laser ablation of great and small saphenous vein incompetence with a 1470-nm laser and radial fiber.

Objective: Scarce information is available on the long-term results of endovenous laser ablation (EVLA) for great saphenous vein (GSV) or small saphenous vein (SSV) insufficiency. We sought to provide data on the status of patients at least 9 years after EVLA.

Methods: In 2018, we undertook a cross-sectional survey of ambulatory patients who had undergone EVLA in our tertiary care center in 2008-2009.

Endovenous laser ablation of great and small saphenous vein incompetence with a 1470-nm laser and radial fiber.

Objective: Endovenous laser ablation (EVLA) of great (GSV) and small saphenous vein (SSV) chronic insufficiency with 1470-nm diode laser and radial fiber yields good short-term results. The aim of this study was to assess its efficacy after at least 12 months of follow-up.

Methods: We performed a prospective interventional cohort study in an ambulatory care/day surgery setting.

Six-year follow-up of endovenous laser ablation for great saphenous vein incompetence.

Objective: Treatment of chronic venous insufficiency of the great saphenous veins by endovenous laser ablation yields good short- and medium-term results, as assessed clinically and technically by echo-color-Doppler. At present, scarce data are available on the long-term results of endovenous laser ablation. We wanted to assess the long-term efficacy of endovenous laser ablation.

Determination of metals by total reflection X-ray fluorescence and evaluation of toxicity of a river impacted by coal mining in the south of Brazil.

Metal (Fe, Mn, Zn, Ni, Cd, and Pb) concentrations in the region of Criciuma (Brazil), a region impacted by coal mining, were determined in water and sediments using total reflection X-ray fluorescence (TXRF) spectroscopy. Samples were collected from the Mãe Luzia River (south Brazil) at five different stations, from the source down to the river mouth (Ararangua estuary). Water and sediment toxicity were also evaluated using bioassays with Daphnia magna as the bioindicator.
