ClinConnect Summary
This clinical trial is studying two different treatments—radiofrequency ablation and microwave ablation—to see which one works better for patients with small saphenous varicose veins. Varicose veins can cause uncomfortable symptoms like swelling, pain, and heaviness in the legs. The trial aims to find out how effective these procedures are in helping patients feel better and improve their quality of life.
To be eligible for this trial, participants need to be between 18 and 90 years old and have a diagnosis of primary varicose veins in their legs. They should be experiencing symptoms like pain or swelling and have a confirmed vein size that meets the study requirements. Only one leg will be treated, and participants must be willing to attend follow-up visits. It's important to note that individuals with certain conditions, such as severe vein issues or those on specific medications, may not qualify for this study. Participants can expect to receive treatment and be monitored for their progress, contributing to research that could help others in the future.
