AB  - Postoperative  venous  thromboembolic  disease  (VTE)  accounts  for  approximately  25%  of  all  VTE  despite  prophylaxis.1  Most  postoperative  patients  will  have  an  intermediate  or  high  pretest  probability  of  VTE.  D-dimer  testing  in  the  postoperative  patient  has  limited  utility  because  of  the  high  frequency  of  elevated  results,  and  the  American  Society  of  Hematology  guidelines  recommend  against  the  use  of  D-dimer  alone  to  diagnose  VTE.2  Computed  tomographic  pulmonary  angiography  and  duplex  ultrasound  are  suggested  as  initial  studies  of  pulmonary  embolism  (PE)  and  deep  vein  thrombosis  (DVT),  respectively,  and  serial  duplex  ultrasound  should  be  used  in  patients  with  high  suspicion  of  DVT  and  an  initial  negative  study.2
