Rate of late radial artery occlusion following cardiac catheterization at Jordan University Hospital

Abstract

Background: A recanalizing-process might decrease the incidence of radial artery occlusion (RAO) at a late assessment postcatheterization opposed to an early assessment. In this study, we evaluated the rate of RAO at a late postcatheterization period. Materials & methods: A retrospective case-control design was adapted including 148 patients who underwent trans-radial cardiac catheterization 7 to 18 months ago. The primary outcome was to assess RAO at the mentioned period while the secondary outcomes were to assess risk factors and symptoms associated with occlusion. RAO was assessed by Doppler ultrasound. Result: Thirteen patients (8.8%) had RAO in a median follow-up time of 13 months. Hand disability as measured by QuickDash score was significantly associated with RAO. Conclusion: This study adds a new insight on late RAO after coronary catheterization in Jordan and the region. Our findings support an ischemic mechanism contributing to long-term hand dysfunction.
