venous ligation

venous ligation,

the ligation of varicose veins whose valves are ineffective, performed to remove weakened parts of tissues in which thrombi might lodge. During surgery the saphenous vein is ligated at the groin, where it joins the femoral vein. A wire device, called a stripper, is threaded through the lumen of the vein from groin to ankle. The wire and the vein are then pulled from the groin incision. Incisions may be made at several sites along the leg. Bleeding is minimal. After surgery a pressure bandage is applied from foot to thigh, and the foot of the bed is elevated 6 to 9 inches, raising the legs above heart level. The patient is encouraged to walk but discouraged from standing or sitting. Cyanosis of the toes indicates possible constriction by the dressings. Elastic bandages remain in place until the seventh day after surgery, when the sutures are usually removed. Possible complications include hemorrhage, infection, nerve damage, and thrombosis.
