Abstract: Introduction: One of the important advantages of the distal transradial access (dTRA) is the significant reduction in the incidence of radial artery occlusion (RAO). There are few reports on the influencing factors for distal radial artery occlusion (dRAO) after cardiovascular interventions via the dTRA. Methods: This retrospective analysis included the clinical data of patients who underwent a cardiovascular intervention via the dTRA. The dRAO was evaluated by ultrasound within 24 hours after the procedure. Multivariate logistic analysis was used to explore the influencing factors for dRAO. Results: The incidence of dRAO was 3.5% (28/805) at 24 hours follow-up after the procedure. In the comparison between the 2 groups, the preoperative distal radial artery (DRA) internal diameter in the dRAO group was significantly smaller than that in the non-dRAO group (p=0.001). The prevalence of DRA inner diameter/sheath outer diameter <1 was significantly higher in the dRAO group than in the non-dRAO group (p=0.013). The number of puncture attempts was significantly greater in the dRAO group than in the non-dRAO group (p=0.007). Multivariate logistic analysis showed that DRA inner diameter/sheath outer diameter <1 was an independent risk factor for dRAO (OR=4.827, 95% CI=1.087–21.441, p=0.039). Conclusions: The incidence of dRAO 24 hours after cardiovascular intervention via the dTRA was 3.5%, and a DRA inner diameter/sheath outer diameter <1 was an independent risk factor for dRAO. Preoperative ultrasound assessment of vessel inner diameter and selection of a sheath with a smaller outer diameter may reduce the risk of dRAO. Clinical Impact: The incidence of distal radial artery occlusion after cardiovascular intervention was 3.5%. The distal radial artery inner diameter/sheath outer diameter <1 was an independent risk factor for distal radial artery occlusion. Preoperative ultrasound assessment of vessel inner diameter and selection of a sheath with a smaller outer diameter may reduce the risk of distal radial artery occlusion. The number of puncture attempts and compression time were not related to distal radial artery occlusion. [ABSTRACT FROM AUTHOR]
