Clinical Trial: Pain During Heat Treatment for Lower Extremity Varicose Veins: Radiofrequency vs. Microwave

U.S., Oct. 31 -- ClinicalTrials.gov registry received information related to the study (NCT07907315) titled 'Pain During Heat Treatment for Lower Extremity Varicose Veins: Radiofrequency vs. Microwave' on Sept. 03.

Brief Summary: This study compares two common heat-based procedures for treating varicose veins in the legs: radiofrequency ablation (RFA) and microwave ablation (MWA). Both treatments use heat to close off diseased veins, but they work differently-RFA heats through direct contact, while MWA uses microwave energy that spreads heat more widely.

The main question is: Which procedure causes less pain during the surgery?

Participants will be randomly assigned to receive either RFA or MWA. Since the surgery is done under local anes...
