U.S., May 15 -- ClinicalTrials.gov registry received information related to the study (NCT06971068) titled 'Vacuum-assisted Laser Ablation (VALA) for Treatment of Large Saphenous Veins' on May 02.
Brief Summary: Endovenous thermal ablation (EVTA), including radiofrequency ablation (RFA) and endovenous laser ablation (EVLA), is considered the main method for the treatment of symptomatic truncal vein reflux. However, there are controversial data concerning their efficacy and safety in ablating large saphenous veins because of high risk of heat-induced thrombosis (EHIT), incomplete ablation and recanalization.1-5 The use of vacuum evacuation of the remaining intraluminal blood during endovenous laser ablation allows to decrease the risk of in...
