ligation /līgā″shən/ [L, ligare, to bind] , n., the procedure of tying off a blood vessel or duct with a suture or wire ligature. It may be performed to stop or prevent bleeding during surgery, to stop spontaneous or traumatic hemorrhage, to prevent passage of material through a duct as in tubal ligation, or to treat varicosities. In venous ligation the saphenous vein is tied above the varicosed part, and the distal parts are removed. After surgery the nurse observes the patient’s feet and legs for circulatory impairment. The foot of the bed is raised to encourage venous return. Ambulation is begun the day of surgery, with elastic bandages for firm support. Analgesics are given as necessary for pain and discomfort. See also ligature, tubal ligation, varicose vein. −ligate, v.
