E-161 Transradial arterial access for neurointervention: the basics, benefits, and tools

Transradial access (TRA) is a feasible method for interventional neurovascular procedures, gaining popularity after becoming the standard access route in cardiovascular interventions. While advantages of TRA include better safety, cost reduction, and patient experience, barriers include a narrow variety of dedicated equipment for radial to neurovascular target vessels, need for further training for physicians and fellows, and physician bias toward Transfemoral access (TFA) due to training and familiarity.This educational poster focuses on the general technical details of TRA, including discussion of the TRA and distal TRA technique, pre-procedure recommendations, patient preparation, possible contraindications, prevention and management of complications which largely consist of spasm and occlusion, and hemostasis protocols. Feasibility of various interventions such as stroke thrombectomy and other neurovascular interventions are described including catheter selection. Also included is the anatomy of the radial artery, the aorta, and its branches within the head and neck, and how this anatomy applies to TRA technical success.Conversion to TFA generally occurs when TRA access is not feasible, typically when there is excessive tortuosity of the radial artery or acute angulation of the left common carotid artery and internal carotid arteries, which may result in approach failure. This educational poster will also cover pre-procedure planning in relation to radiological findings a...
