VARICOSE VEINS

Veins that have become stretched, distended and twisted.  The superficial veins in the legs are often affected although it may occur elsewhere.  Causes include congenitally defective valves, obesity, pregnancy and thrombophlebitis (inflammation of the wall of a vein with secondary thrombosis in the affected part of the vein).  Elastic support is a common treatment although alternatives are sclerotherapy and phlebectomy.
