The incidence of postoperative symptomatic VTE was 5.9% in the conventional prophylaxis group and 0.8% in the intensive prophylaxis group.

Eight patients with deep vein thrombosis on preoperative screening who underwent inferior vena cava filter insertion did not develop postoperative symptomatic VTE.
