We examined the occurrence ofVTE on the preventive anticoagulant therapy (fondaparinux, enoxaparin) cases and comparedthe VTE positive group (VTE+) with the VTE negative group (VTE-).[Patients and Methods]As the object of our present study, we took 246 patients whom underwent first THR during thetwo years from August 2007 to July 2009. 37 were men and 209 were women (mean age 62.9).After the operations on all of the patients, we took multi-detector row CT scan (MDCT) thenext day and diagnosed the existence of VTE. 42 were VTE+ (17.1%) and others were VTE-.Then, we compared age, BMI, blood loss, operation time, plasma levels of two coagulationactivation markers (SFMC[μg/ml], D-dimer[μg/ml]) between VTE+ and VTE-. Furthermore,we measured and evaluated the distance from the surface of proximal tibia to the point of deepvein thrombosis (DVT) in the calf of 35 DVT positive patients.[Results]The mean age was 66.7 in VTE+ and 62.1 in VTE-, which makes VTE+ older than VTE-.Therewere no significant difference in BMI, blood loss and operation time between VTE+ and VTE-.The day after the operations, SFMC was 20.6±19.8 in VTE+, and 13.4±22.6 in VTE-. The D-dimer of seventh postoperative day was 12.7±7.0 in VTE+, and 10.0±5.0 in VTE-. The scoresof SFMC and D-dimer in VTE+ were higher than those of VTE- and there were significantdifference in both scores (p
