Patients were matched by propensity score to a control group of 212,984 patients without varicose veins. They are generally caused by pregnancy or blood vessels weakening with age.

About a quarter of US adults have varicose veins. Obesity and a family history of the condition also increases the risk.

Response: To examine whether greater severity of varicose veins was associated with higher risk would be our recommendation for future research.

The study found people with varicose veins were at a five times increased risk of developing a deep venous thrombosis (DVT) - a clot in the legs which can lead to amputation or even death, the Daily Mail reported.

Dr. Gregory Piazza, cardiovascular medicine specialist at Brigham and Women's Hospital, said the study has a "number of strengths", including the large number of people studied.

Every year around 25,000 people in the United Kingdom bite the dust from a blood clot in a vein, and the condition is additionally the third driving reason for heart assaults and strokes. Because of the nature of the study, researchers did not intervene and were unable to control other elements and factors that may have impacted the outcomes.

Still, the association between varicose veins and DVT was strong, he added. Moreover, patients with chronic venous diseases have increased leukocyte adhesion and more activated leukocytes.

The study was supported by grants from Chang Gung Medical Research Program, and from the Taiwan Ministry of Science and Technology.

Though the study confirms that associations between varicose veins and blood clots exist, it does not help to estimate the strength of this association, Kindzelski said.
