Anatomical consideration of the radial artery for transradial coronary procedures: arterial diameter, branching anomaly and vessel tortuosity.

Background: The radial artery is currently regarded as a useful vascular access site for coronary procedures. Adequate anatomical information of the radial artery should be helpful in performing the transradial coronary procedure. Therefore, we tried to evaluate the size of radial artery, the incidence and clinical significance of anomalous branching patterns and tortuosity of the radial artery related with transradial coronary procedure.

Procedural outcomes of repeated transradial coronary procedure.

We evaluated the changes in radial arterial diameter and the procedural outcomes of repeated transradial procedures through the same radial artery in 117 cases. No significant differences were found in the mean diameter of the radial artery between preprocedure and 1 day after procedure on initial and repeated procedures. However, the mean radial arterial diameter was significantly decreased from 2.

A case of transradial carotid stenting in a patient with total occlusion of distal abdominal aorta.

We report a case with severe carotid stenosis in which carotid stenting was performed via the radial artery due to total occlusion of distal abdominal aorta. The radial approach offers a potential alternative in cases in which the femoral approach is problematic.
