Varicose veins are frequently treated by surgically eliminating the “bad” veins.
Varicose veins may be an early warning sign of potentially deadly blood clots, suggests a study published Tuesday in the journal JAMA.
Enlarged and gnarled varicose veins and deep venous thrombosis, a clot that forms in the deep veins of the body, are strongly associated, the Taiwanese researchers found.
Though they looked at the health records of more than 425,000 adults, the researchers say that even more work is needed to understand whether this relationship is one in which varicose veins directly cause blood clots or whether the two conditions simply have a similar origin.
Occasionally, varicose veins can form a painful blood clot with inflammation of the vein, a condition called thrombophlebitis.
