    Introduction: Most neuroendovascular interventions rely on a transfemoral approach to the intracranial circulation, however this is sometimes not possible due to complex aortic arch anatomy or femoral arterial disease. Transradial arteriography and intervention is well established in interventional cardiology and there have been some reports of successful neurointervention using this technique. The incidence of radial artery occlusion or other access site complication after transradial access is directly related to the outer diameter of the sheath used to access the artery.

    Methods: We describe a technique to directly access the radial artery with a 070 Neuron catheter, without the need for a large 6-F sheath, for cerebrovascular interventions.

    Results: Two successful cases are described in which this technique was used. Case one describes the successful Y-stent placement for coiling of a basilar tip aneurysm, and case two describes coiling of a ruptured PICA aneurysm.

    Conclusions: The 070 Neuron catheter can be used in a direct access transradial approach to the cerebrovascular circulation for complex interventions without a radial sheath, thereby maximizing guide catheter diameter and minimizing the radial arteriotomy size.

    Patient Care: Using this novel technique, radial arteriotomy size can be minimized, thereby potentially reducing the risk of access site complication, while allowing for excellent vertebral artery access for cerebral intervention.

    Learning Objectives: 1) Review risks associated with transradial vascular access. 2) Review new technique to obtain large distal access via an 070 Neuron catheter while minimizing the diameter of the radial arteriotomy.
