Registry for Chronic Venous Disease Incidence and Natural Course

This is a long-term observational registry studying the natural course of chronic venous disease — conditions affecting the veins of the legs, such as varicose veins and venous insufficiency — in family members of the researchers themselves. The study uses annual physical exams and ultrasound to track how the veins change over time without any treatment. You may be eligible if: - You are a family member of a participating researcher (spouse, children, siblings, or parents) or are the researcher themselves - You are 10 years old or older - You can attend annual clinical and ultrasound assessments You may NOT be eligible if: - You have previously received any invasive treatment for chronic venous disease (such as surgery, laser, or sclerotherapy) - You have a history of venous thrombosis (blood clot in a vein) either in your history or at the time of enrollment Talk to your vascular specialist if you are a family member of a researcher involved in this study and want to participate in long-term vein health monitoring.
