Frequency of Loss of Radial Pulse after Transradial Coronary Intervention

Abstract

Objectives: Loss of radial pulse following transradial coronary intervention (TRI) is a known complication that can limit future radial artery access and preclude its use as an arterial conduit. This study aims to determine the frequency of radial pulse loss post-transradial coronary catheterization. Methodology: This descriptive case series was conducted at the Cardiology Department, Jinnah Hospital, Lahore, over six months (March 26, 2023 – September 26, 2023). 110 patients fulfilling the inclusion criteria were enrolled. Informed consent was obtained, and transradial coronary catheterization was performed under local anesthesia by a single cardiology team. Patients were monitored for 24 hours post-procedure for loss of radial pulse, and all were managed per guideline-directed medical therapy. Results: Among 110 patients, the mean age was 59.32 ± 3.83 years, BMI 27.11 ± 4.02 kg/m², radial artery diameter 2.63 ± 0.16 mm, procedure duration 14.31 ± 10.99 min, and sheath dwell time 10.76 ± 2.52 hours. Males comprised 43.6% (n=48), while females constituted 56.4% (n=62). The overall frequency of radial pulse loss was 22.7% (n=25). Conclusion: Loss of radial pulse is a common complication following transradial access. Ensuring radial artery patency should be an integral part of all transradial procedures to minimize this risk and preserve the radial artery for future use.
