Quantitative angiographic radial artery diameter measurement and its relationship with common variables: A cross-sectional study

Different techniques are available for peripheral artery diameter measurement. Angiographic assessment of the radial artery (RA) during coronary procedures offers a potentially cost effective, less hazardous and accurate method. Besides, it can provide some additional information. This cross-sectional study aims to calculate RA diameter (RAD) angiographically and to investigate its relationship with common parameters. A total of 230 patients undergoing percutaneous trans-radial coronary procedures at a tertiary cardiac hospital in Dhaka were included in the study to measure RAD using quantitative coronary angiography software. Patients' height, weight, body mass index (BMI), and wrist circumference were recorded. The presence or absence of hypertension and diabetes was searched. The mean diameter of the RA was 2.35 ± 0.41 mm, and wrist circumference was 16.34 ± 1.05 cm. Males had significantly larger RADs (P < .001). No significant relation was encountered between RAD and hypertension (HTN) and diabetes mellitus. There was no significant correlation of RAD with BMI (r = -0.028, P = .676). However, wrist circumference was found to be positively associated with RAD (R = 0.214, P = .001). RAD although had a positive correlation with wrist circumference, but there was no relationship with HTN, diabetes mellitus, and BMI.
