Occurrence of ischemic complications after transulnar coronary procedures is virtually absent. The presence of a complete deep palmar arch in approximately 95% of the population as well as the great capacity of the collateral circulation of the hand might justify these findings. We report the occurrence of complications in 62 patients submitted to coronary procedures through the transulnar approach, without assessment of the integrity of the deep palmar arch by the inverse Allen's test. The rate of asymptomatic occlusion of the ulnar artery was 3%, without any ischemic complication. We believe the performance of Allen's test is not necessary when using transulnar access.
