Veins have the important role of transporting blood in your body. An abnormality in vein function can causes diseases such as varicose veins and deep vein thrombosis. Venous diseases are caused by blood disorders, smoking, birth control pills, hormone replacement therapy, injuries to the vein and obesity. Interventional radiologists can treat these diseases by applying suction to aspirate blood clots and injecting clot-dissolving medicines to reduce thrombosis.
