Abstract

Background The transradial approach (TRA) is frequently used for neurointerventional procedures as it is safer, improves patient comfort, and decreases costs and procedural time in comparison with the transfemoral approach (TFA). Patients with arteria lusoria, or an aberrant right subclavian artery (ARSA), provide a unique challenge for cerebral angiography and interventions when using the TRA. Objective To examine the hypothesis that the extreme angulation encountered while accessing the great vessels from the right TRA could be overcome by reversing the approach to the left distal TRA (dTRA). Methods A prospectively maintained database of transradial neurointerventional cases since 2018 was searched. Six cases from 850 were identified, in which the left dTRA was used. Three cases were for patients with an ARSA. For the three cases of interest, patient history, pathology, imaging, and access techniques were reviewed. Results Two diagnostic cerebral angiography cases and one intervention were successfully performed through a left dTRA. Conclusions Proper positioning of the left wrist and familiarity with forming the Simmons catheter can overcome this anatomical challenge. This technique and results further demonstrate that the left distal radial artery is a feasible access site for catheterization of bilateral carotid, left vertebral, and right subclavian arteries for patients with an ARSA.
