Background:   We sought to investigate the rate of radial artery occlusion (RAO) after same-day dual radial artery puncture. The trans-radial arterial approach (TRA) for diagnostic and interventional procedures has risen significantly in the United States. Although becoming more commonly performed, TRA is not without risk, and a potential complication is RAO. The rate of RAO after same-day dual artery puncture is unknown.Methods:   A retrospective analysis of 27 patients who underwent same-day dual radial artery puncture for percutaneous coronary intervention (PCI) at our institution (Providence Heart Institute in Southfield, MI, USA) from November 2011 to December 2013 were included after initially presenting for cardiac catheterization at a non-PCI-capable facility. The study patients were asked to follow up for evaluation of the radial artery, including obtaining a duplex ultrasound evaluation.Results:   The mean age of the patients was 65 years old with 66% of the patients being male. Of the 27 study participants, there were no symptoms reported that were related to RAO. Overall, one (3.7%) patient had an absent radial pulse. The modified Allen’s test was normal in all of the patients with a mean return of palmar flush time of 4 seconds. Duplex ultrasound revealed subtotal RAO in four (14.8%) patients and no patients experienced total occlusion following the intervention.Conclusion:   Dual radial artery puncture appears to be a well-tolerated and viable strategy in patients that are transferred to a PCI-capable hospital for coronary interventions.
