Abstract
Klippel-Trenaunay syndrome (KTS) is also associated with venous thrombosis originating from varicose veins in the lower extremities, pulmonary embolism, and pulmonary hypertension. This study describes the anesthetic management of laparoscopic cholecystectomy in a 54-year-old male KTS patient with orthostatic hypotension due to massive varicose veins in the lower extremities and pulmonary thromboembolism. Compressing the varicosities with an elastic bandage can maintain stable circulatory dynamics even under general anesthesia management to prevent position and insufflation-induced changes that can occur spontaneously.
