Maturing institutional experience with the transradial approach for diagnostic cerebral arteriography: overcoming the learning curve

Background Despite growing interest in the transradial approach for neurovascular procedures, prospective data about the learning curve for neurointerventionalists adopting this approach are limited. Methods A subsequent prospective series of 50 consecutive right transradial diagnostic cerebral arteriograms was compared with our initial institutional experience using a procedural staging system. The primary outcome was the ability to achieve the...
