Objective: To describe initial experience of transradial access (TRA) for non-coronary intervention performed at body interventional radiology unit.
Materials and Methods: A retrospective descriptive study was performed and included 31 cases from 27 patients that underwent TRA in the present study’s unit between May 2018 and January 2019. All cases were pre-operatively evaluated for radial artery size by ultrasound (US) and verified palmar arch patency using Barbeau test. To proceed to TRA, the radial artery diameter must be at least 1.8 mm and the Barbeau test must not be classified in type D. The primary endpoint was success rate. Secondary endpoints were patency of radial artery and other access site complication after TRA.
Results: The technical success rate was 100% without crossover to transfemoral access (TFA). Asymptomatic radial artery occlusion (RAO) was observed in four cases (12.9%) using US at 24-hour after the procedure. According to statistical analysis, none of the present studied parameters showed statistically significant association with the RAO. The other access site complication detected was pseudoaneurysm, which was found in two cases.
Conclusion: TRA is a promising alternative access for non-coronary intervention. Vascular access site complications are rarely clinically significant but nevertheless still a concern.
