Outcomes of graft angiography with distal radial access: a retrospective cohort study

Background: This retrospective cohort study aimed to compare the outcomes of graft angiography using these two approaches.Methods: Medical records and angiographic data of adult patients who underwent graft angiography between January 2020 and December 2022 were analyzed.Results: The study included 452 patients in the distal radial access (DRA) group and 960 patients in the femoral access group. Angiographic characteristics showed a higher prevalence of triple vessel disease in the femoral access group (29.8% vs. 20.8%; p = 0.012). The DRA group had a procedural success rate of 93.0%, while the femoral access group had a higher success rate of 95.8%. The odds ratio was 0.66 (95% CI: 0.46-0.94), indicating lower odds of procedural success in the DRA group.Conclusion: Our study suggests that both DRA and femoral access are effective and safe approaches for graft angiography after coronary artery bypass surgery.
