In a prospective consecutive series, 53 revision hip arthroplasties were performed in 51 patients. Pre- and postoperative Duplex ultrasonography examinations were reviewed by an independent, experienced radiologist. Three of 51 patients (53 procedures) had evidence of chronic deep venous thrombosis (DVT) or other venous abnormality preoperatively, yielding an incidence of 5.6%. One (1.9%) patient developed an acute DVT postoperatively despite pharmacological and mechanical preventative measures. These results indicate the use of preoperative ultrasonography as a screening tool prior to revision hip arthroplasty is not warranted based on the low incidence of acute or chronic DVT detected preoperatively. Long-term anticoagulation, when necessary, can be based on the findings of a postoperative scan.
