Outcomes with Distal Transradial Access in Patients With Advanced Chronic Kidney Disease

Radial artery occlusion (RAO), a complication of transradial access, has an incidence of 4.0% to 9.1% in patients with advanced chronic kidney disease (CKD) and may preclude its use creation of arteriovenous fistula. Distal transradial access (dTRA) has lower rates of RAO compared with TRA, but prior studies excluded patients with advanced CKD. This was a single center study of patients with advanced CKD who underwent coronary procedures with dTRA from January 1, 2019 to May 12, 2022 who were retrospectively evaluated for radial artery patency in follow-up with reverse Barbeau testing or repeat access of the artery. Of 71 patients, 66% were on hemodialysis and the remainder had CKD 3 to 5. Access was ultrasound-guided, and all received adequate spasmolytic therapy and patent hemostasis. Proximal radial arteries were patent in 100% of the patients at follow-up. Our data suggest that dTRA is safe for patients with advanced CKD and preserves radial artery patency.
