Common ground, different path: Ulnar artery access for interventional neurovascular procedures

Background Recently, radial artery access has gained popularity for interventional neurovascular procedures due to patient comfort and fewer complications. However, there are instances where the radial artery approach is not feasible. In such cases, trans-ulnar artery access (TUA) can offer an alternate route. There is limited data regarding neuro-interventional procedures performed via this approach. This study aims to evaluate the feasibility and safety of trans-ulnar approach for a wide range of interventional neurovascular procedures. Materials and methods The data for all patients who underwent ulnar artery access for diagnostic or interventional neuroradiology procedures was retrospectively collected between September 2020 and March 2021. Patient demographics, procedural details, procedure success, and complications were recorded. Results During the study period, 23 patients underwent 24 trans-ulnar approach procedures. The mean age of patients was 50.1 +/- 14.2 years. Fourteen diagnostic cerebral angiograms and ten interventional procedures were performed. All procedures were successfully completed via trans-ulnar approach without a switch to alternate access. No major access site complication was observed. Conclusion Ulnar artery access is a safe and feasible option for neurovascular procedures. It can be effectively utilized for diagnostic cerebral angiography and a wide range of interventional procedures.
