Purpose:Using the 64-channel multidetector-row computed tomographic venography (MDCT venography), we tried to know the incidence of the deep vein thrombosis (DVT) after total knee arthroplasty and the effectiveness of MDCT venography.
Material and Methods : From April 2006 to December 2006, two groups of 280 consecutive patients, who underwent primary total knee arthroplasty, were enrolled in this study. We performed antithrombotic chemotherapy on the patients who were confirmed to have symptomatic DVT.
Results: For the first 140 consecutive cases, DVT was found in 48 (34%) patients and only 5 (3.6%) showed clinical symptoms of DVT. For the next 140 cases, 12 (8.6%) cases showed symptoms of DVT and in them 7 (5.0%) of these cases was diagnosed with symptomatic DVT. All the patients had recovered at the last follow-up and no other complications occurred in our series.
Conclusion:Sixty four-channel MDCT venography is valuable as a diagnostic test for DVT after total knee arthroplasty in terms of efficacy and accuracy. Antithrombotic chemotherapy is recommended after confirming the diagnosis with MDCT venography only for the patients with symptoms of DVT.
