Supports transradial safety in selected patients with normal Allen test; leaves open need for RCTs on unselected populations and long-term outcomes.
Transradial coronary angioplasty is associated with a low incidence of persistent radial artery occlusion (2.8% at 1 month) that is clinically asymptomatic in patients with a normal Allen test.
Stella et al. (1997) studied this question.
