Frequency of Radial Artery Occlusion in Patients Undergoing Percutaneous Cardiac Catheterization by Radial Access

Abstract

Objectives: To assess the frequency of radial artery occlusion (RAO) in patients undergoing percutaneous cardiac catheterization. Methodology: A descriptive cross sectional study was carried out at cardiology department Jinnah hospital, Lahore from April – October 2018. One hundred thirty one consecutive patients who had undergone percutaneous cardiac catheterization via the trans-radial approach were enrolled in the study. Post procedure patients were followed in the ward and after 24 hours, Allen’s test was used for checking the patency of the radial artery. Color Doppler USG was performed in the patients with absent radial artery and RAO was confirmed. Data was entered and analysed in SPSS version 21.0. Results: Out of 131 patients who had undergone for percutaneous cardiac catheterization 63.4% were male and 36.6% were female. Among these cases radial artery occlusion was detected in 52 (39.7%) patients. No statistically significant difference was found with effect modifiers like age, gender, duration of procedure and type of intervention statistically insignificant difference was observed (P>0.05). Conclusion: A considerable number of patients were observed with radial artery occlusion with trans-radial approach thought statistically insignificant difference was noted among all ages, gender or type of intervention suggesting a detailed evaluation of radial artery patency should be done before hospital discharge.

Loss of Radial Artery Pulse after Coronary Catheterization Through Trans-radial Route in Patients Acute Coronary Syndrome

“…Contrary to our findings, a significantly higher proportion of radial artery occlusion has been reported in a study conducted by Butt UM et al 12 in our local population. They included 131 patients who underwent percutaneous cardiac catheterization via the trans-radial approach and 39.7% of them were found to have radial artery occlusion on color Doppler ultrasound after 24 hours of the procedure.…”

“…As it has been proven that rate of radial artery occlusion after trans-radial cardiac catheterization is negatively associated with timing of assessment. 8 Hence, the possible explanation for differences in the rates of radial artery occlusion in our study and the study conducted by Butt UM et al 12 is due to the differences in the time of assessment. Similarly, another study by Sadaka MA et al 13 Study further reported radial artery diameter, manual compression, age, and female gender were reported to be independent predictor on multivariable analysis.…”

“…A sample size of 115 patients was calculated based on expected prevalence guess of 39.7% 12 , 95% confidence level, and 9% margin of error. Data were summarized by computing mean ± standard deviation (SD) or median [interquartile range (IQR)] for continuous and frequency (%) for categorical variables.…”

Radial Artery Occlusion After Transradial Access for Coronary Interventions

“…Most studies check the pulse to assess radial artery patency before hospital discharge. In the United States, 20% will determine RAO incidence with echo-Doppler or oximetry/plethysmography testing [12,13].…”
