Abstract

INTRODUCTION: In recent years, transradial cardiac catheterization has become the preferred method. However, it can result in a significant complication known as radial artery occlusion (RAO). The medical management of RAO remains controversial, especially with the emergence of novel oral anticoagulants. Nevertheless, there is limited data on the use of these agents for treating RAO, which is the focus of this study using apixaban. METHOD: This pilot double-blinded randomized clinical trial involved 30 patients who developed RAO following transradial coronary angiography. The patients were randomly assigned to receive either apixaban (2.5 mg twice daily) or a conservative approach for 30 days. Doppler ultrasonography was performed at baseline and at the end of the intervention to assess radial artery diameter and the resolution of arterial patency. Demographic, medical, medication, and clinical characteristics were collected. RESULTS: The mean age of the studied population was 59.43±12.14 years, and the majority were males (60%). Radial artery resolution was observed in 21 (70%) patients, independent of medication use. There was no significant association between resolution and age (P-value=0.62), gender (P-value=0.74), body mass index (P-value=0.23), smoking (P-value=0.64), diabetes (P-value=0.999), hypertension (P-value=0.74), statins (P-value=0.999), antiplatelet therapy (P-value=0.999), length of angiography (P-value=0.216), or follow-up arterial diameter (P-value=0.304). Recanalization occurred in 13 (86.7%) cases in the apixaban treatment group, compared to 8 (53.3%) individuals in the control group, indicating a significant difference (P-value=0.046). CONCLUSION: The study findings suggest no demographic, medical, medication, or clinical factors were associated with arterial recanalization. However, a one-month treatment with apixaban at a dose of 2.5 mg twice daily appeared to be effective. © 2023, Isfahan University of Medical Sciences(IUMS). All rights reserved.
