title: The incidence of venous thromboembolism before and after total knee arthroplasty using 16-row multidetector computed tomography.
abstract: We performed a prospective study to determine the incidence of venous thromboembolism (VTE) using 16-row multidetector computed tomography (MDCT). The study included 71 patients who underwent total knee arthroplasty between September 2004 and March 2009. Multidetector computed tomography was performed 4 days before and after surgery. No patient had any presurgical symptoms of VTE. Presurgical and postsurgical incidences of pulmonary thromboembolism plus deep vein thrombosis were 0% and 13%, respectively; pulmonary thromboembolism alone, 1% and 3%, respectively; and deep vein thrombosis alone, 8% and 34%, respectively. Because asymptomatic VTE was noted in 9% of patients before surgery and 51% after surgery, we conclude that performing MDCT before and after total knee arthroplasty may be useful to clarify the incidence of VTE and to develop appropriate strategies for treatment and prevention.
