Anatomical features of the radial artery in the Xinjiang population in China and its impact on the transradial coronary intervention procedure

Background: The anatomical features of the radial artery (RA) influence the transradial coronary intervention. The aim of this study is to discuss the anatomical features of the RA in the Xinjiang population and to guide interventionists in decreasing complications and improving success rates. Materials and methods: We enrolled 1731 patients in this study. All relevant basic information was recorded in detail, and the RA diameter was examined. Patients were divided into a RA variation group and a RA non-variation group; univariate and multivariate factor analyses were performed to evaluate the relevant factors for RA diameter and the predictive value of the variable factors in RA variations. Results: The mean RA diameter for all patients was 3.01 +/- 0.14 mm. The multi-factorial analysis showed that height, gender, and occupation are significantly associated with RA diameter (p < 0.05). The incidence of RA variation was 4.97% (86/1731). Multi-factorial analysis showed that: gender (OR 2.72, 95% CI 1.469-5.037, p < 0.01), occupation (OR 2.228, 95% CI 1.0.000-0.012, p < 0.001) and RA inner diameter (OR 0.002, 95% CI 0.000-0.012, p < 0.001) are significantly associated with the incidence of RA variation. Conclusions: The mean RA diameter in the Xinjiang population was 3.01 -+/- 0.14 mm, height, gender; occupation are associated with RA diameter; gender; farmer; RA diameter are associated with RA variation. These factors can guide the interventionists to choose the appropriate equipment before the operation then can increase the efficiency of operation and prevent from the complications.
