Radial Access Intervention

Abstract

Leveraging from the interventional cardiology experience, the transradial access (TRA) for neurointervention has also started to become more used for both diagnostic and therapeutic procedures. A growing body of evidence is showing a superiority of the TRA compared with the conventional transfemoral access (TFA) in terms of access site complications (ACSs), patient satisfaction and preference, hospital length of stay, and cost. Outcomes via the transradial are noninferior, and at times superior, in select neuroendovascular procedures. Future advancements in technology with radial-specific catheters and further operator experience will aid in the full adoption of the TRA for endovascular procedures.
