Feasibility and initial experience of left radial approach for diagnostic neuroangiography

Abstract Neuroangiography has seen a recent shift from transfemoral to transradial access. In transradial neuroangiography, the right dominant hand is the main access used. However, the left side may be used specifically for left posterior circulation pathologies and when right access cannot be used...
