Graded pressure stockings significantly reduced the incidence of venographically determined deep venous thrombosis (DVT) after total hip arthroplasty. Seventy-six patients were studied; the incidence of DVT was 54% in 41 control patients and 20% in 35 patients who wore stockings. Administration of blood during the operation and in the first 24 h after operation, if given in excess of blood loss, was associated with a significantly increased risk of developing DVT. The application of graded pressure stockings and the avoidance of unnecessary perioperative blood transfusion are worth while in the management of total hip arthroplasty.
