Purpose To evaluate safety and feasibility of distal radial artery (DRA) access for noncoronary interventional radiology procedures.

Materials and Methods All interventional radiology procedures by means of DRA puncture from July 2017 to August 2018 were retrospectively reviewed. Eighty-two punctures in 56 patients were included, mostly in male patients (84% vs 16%). Mean age was 67.8 years (range, 33.3–87.3 years); mean height was 172 cm (range, 142–190 cm); and mean weight was 83 kg (range, 43–120 kg). Procedural characteristics, technical success, and complication rates were gathered from the medical records and follow-up ultrasound when available. Prerequisites for DRA access were adequate radioulnar collateral circulation, sufficient radial artery diameter, and informed consent in patients initially intended for conventional transradial access.

Results Procedures included transarterial chemoembolization (n = 34), yittrium-90 pretreatment angiography (n = 21), yittrium-90 administration (transarterial radioembolization; n = 20), and embolization of visceral organs (n = 7). Both 4-Fr (n = 35) and 5-Fr (n = 46) sheaths were used. Technical success of DRA access was 97.6%, with conversion to transfemoral access in 2 cases (2.4%). No major complications were reported as a result of DRA access.

Conclusion DRA access is a feasible and safe technique for abdominal interventional radiology embolization procedures. No radial artery occlusion or other major complications were observed in patients who underwent follow-up ultrasound.
