Abstract
Objective
To evaluate the frequency of hemorrhagic complications on abdominal computed tomography
(CT) in patients with warfarin therapy and its correlation with intensity of anticoagulation.
Materials and methods
We included 646 patients who received warfarin therapy with international normalized
ratio (INR) greater than 3.0 and abdominal CT within 1 month after INR measurement.
Results
Seventy-four patients (11.5%) showed hemorrhagic complications on abdominal CT. Frequency
of hemorrhagic complications significantly correlated with intensity of anticoagulation
(P<.001).
Conclusion
Hemorrhagic complications on abdominal CT in patients with warfarin therapy were not
rare, and it occurred more frequently in patients with higher INR.
