Varicose vein surgery and deep vein thrombosis

A questionnaire was sent to 363 members of the Vascular Surgical Society of Great Britain and Ireland about their use of deep vein thrombosis (DVT) prophylaxis at the time of varicose vein surgery. Replies were received from 289 surgeons (80 percent), of whom only 29 percent regarded varicose veins as an important risk factor for DVT. Only 12 percent used subcutaneous heparin prophylaxis routinely, while 71 percent did so selectively, being influenced by a history of thromboembolism (95 percent), obesity (47 percent), age (35 percent), recurrent varicose veins (22 percent) and inpatient status (16 percent). At the end of the operation 52 percent applied crepe bandages, 25 percent other bandages, 13 percent stockings and 10 percent Tubigrip. Subsequently, antiembolism stockings were prescribed by 55 percent. There is a wide variation in opinion regarding DVT prophylaxis for patients having varicose vein surgery, which has both clinical and medicolegal implications.
