Abstract

This article focuses on an in vitro study investigating the impact of cleaning agents on the power output of endovenous laser ablation (EVLA) catheters used to treat incompetent truncal veins. The study found that povidone-iodine significantly reduces the laser power emitted from a 1470 nm radially firing catheter tip compared to normal saline or a dry tip, potentially lowering the actual energy delivered during treatment. Although wiping off povidone-iodine partially restores power output, residual staining still decreases emission. The authors note that clinical studies are needed to determine whether these laboratory findings affect EVLA treatment outcomes.
