Background: Transulnar approach (TUA) was comparable to the transradial approach (TRA) in terms of efficacy and safety in the presence of extensive operator experience in the TUA. Without adequate experience, there was an increase in time, and number of punctures, to successful access. Objectives: The aim of the study was to compare the in-hospital safety of duplex ultrasound (DUS) assisted TUA to those of DUS-assisted TRA. Methods: All patients had preprocedural DUS assessment. Patients who needed urgent procedures (e.g., ST-elevation myocardial infarction) or had a history of upper extremity arterial disease were excluded. The patients were randomized into TUA or TRA arms. The primary endpoint was a composite of in-hospital vascular access complications (bleeding, limb ischemia, local pain, spasm, and need for crossover). The timing to successful puncture, total number of punctures, total procedural time, fluoroscopy time, amount of contrast, and radiation dose were compared between the two arms as well. Results: A total of 104 patients were randomized into TUA (n = 50) or TRA (n = 54) arms. There was no statistically significant difference between both arms in terms of the primary endpoint (TUA vs. TRA: 37.5% vs. 28.6% respectively, P = 0.33). Apart from an increase in the incidence of access site pain (28% vs. 7%, respectively, P = 0.006), there was no statistically significant difference between the two approaches in terms of time to successful access, number of punctures, total procedural time, fluoroscopy time, or contrast and radiation doses. There was no clinically detectable limb ischemia in both arms on 30-day follow-up. Conclusions: This study demonstrated that there was no difference in safety between DUS-assisted TRA and TUA. In the presence of DUS, TUA becomes a viable alternative arterial access even with the lack of previous TUA experience. More prolonged follow-up is needed to exclude late subclinical events related to the TUA.
