Importance of the Familial Factor in Varicose Disease

Abstract

One hundred and thirty-four families were examined: 67 patients and their parents and 67 controls and their parents. A total of 402 subjects were examined. The results demonstrated a prominent role of heredity in the development of varicose veins (P < .001). The risk of developing varicose veins for the children was 90% when both parents suffered from this disease, 25% for males and 62% for females when one parent was affected, and 20% when neither parent was affected.
