Graft Angiography Through Right Radial Artery: A Retrospective Cohort Study

Abstract

OBJECTIVE: The objective of this retrospective cohort study was to evaluate the efficacy and safety of graft angiography through the right radial artery. METHODS: A total of 1,634 patients who underwent graft angiography through the right radial artery were included in the study. Baseline characteristics, angiographic features, procedural parameters, and outcomes were analyzed. The study population was compared with a control group of 1,000 patients who underwent graft angiography through other access routes. Statistical analysis was performed to assess differences between the groups. RESULTS: The procedural success rate for graft angiography through the right radial artery was 95.6%. The most common indication for angiography was postoperative follow-up (53%), followed by symptoms of angina or ischemia (32.6%). Complications were infrequent, with bleeding being the most common adverse event (2.3%). Other complications, such as hematoma formation, pseudoaneurysm, radial artery occlusion, and nerve injury, were rare. Procedural parameters, including fluoroscopy time, contrast usage, and total procedure time, were comparable between the study population and the control group. Comparison with the control group revealed a significantly higher incidence of bleeding in the study population (p = 0.002), with an odds ratio of 2.53 (95% CI: 1.40-4.59). However, there were no statistically significant differences in other complications. Procedural parameters showed no significant differences between the study population and the control group. CONCLUSION: Graft angiography through the right radial artery demonstrated a high procedural success rate and relatively low complication rates.
