Do factors such as operator, arterial access, and stenting strategy influence fluoroscopy time and radiation dose during ad hoc one-vessel PTCA?
Absolute Event Rate: 17% vs 12%
p-value: p=<0.001
Radiation exposure during one-vessel PTCA is strongly dependent on the operator, arterial access (higher with radial), and stenting strategy (lower with direct stenting).
Larrazet et al. (2003) conducted an observational in Coronary artery disease requiring one-vessel PTCA (n=402). Radial access vs. Femoral access was evaluated on Median fluoroscopy time (minutes) (p=<0.001). During one-vessel PTCA, radial access significantly increased median fluoroscopy time compared to femoral access (17 vs 12 min, P<0.001), as did stenting with pre-dilation versus direct stenting.
