Feasibility and safety of using the radial artery approach for the Wada test: A case report

Abstract

The Wada test is used to lateralize the dominant hemisphere in epilepsy patients prior to surgery. Either amobarbital, methohexital, or propofol is injected via a transfemoral catheter into a unilateral carotid artery, briefly suppressing the ipsilateral cerebral hemisphere to allow functional evaluation of the opposite side. Here, we highlight and propose a radial artery approach for the Wada test, allowing easier arterial access, better patient comfort, and ample procedural efficacy.
