Key result
Distal transradial access in low BMI patients had similar puncture success to conventional access (96.6% vs 97.4%, P=0.846) but lower radial artery occlusion (4.0% vs 33.3%, P=0.007).
Why the study?
The study aimed to investigate the efficacy and safety of coronary intervention via distal transradial access (dTRA) in patients with low body mass index (BMI).
Does coronary intervention via distal transradial access (dTRA) improve procedural outcomes and safety compared to conventional transradial access (cTRA) in patients with low BMI?

In patients with low BMI, distal transradial access for coronary intervention reduces radial artery occlusion and compression time compared to conventional access, despite a lower one-needle puncture success rate.
The study aimed to investigate the efficacy and safety of coronary intervention via distal transradial access (dTRA) in patients with low body mass index (BMI). A total of 67 patients with low BMI who underwent coronary intervention, comprising 29 patients via dTRA and 38 patients via conventional transradial access (cTRA), were retrospectively included. There was no significant difference in the puncture success rate between the two groups (dTRA 96.6%, cTRA 97.4%, P = 0.846 ). Compared with the cTRA group, the success rate of one-needle puncture in the dTRA group was lower (51.7% vs. 81.6%, P = 0.020 ). The compression haemostasis time in the dTRA group was shorter than that in the cTRA group ( P < 0.001 ). However, the incidence of radial artery occlusion was lower in the dTRA group than in the cTRA group (4.0% vs. 33.3%, P = 0.007 ). In conclusion, coronary intervention via dTRA was safe and effective in patients with low BMI.

Li et al. (2022) conducted a cohort in Low body mass index requiring coronary intervention (n=67). Distal transradial access (dTRA) vs. Conventional transradial access (cTRA) was evaluated on Puncture success rate (p=0.846). Distal transradial access in low BMI patients had similar puncture success to conventional access (96.6% vs 97.4%, P=0.846) but lower radial artery occlusion (4.0% vs 33.3%, P=0.007).
