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 1month 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.
