The RADIUS study is a prospective observational registry designed to collect real-world data regarding radial and ulnar artery access in percutaneous vascular interventions. The study aims to evaluate procedural characteristics, access-site complications, procedural success, and short-term clinical outcomes associated with transradial and transulnar vascular access.
Patients undergoing routine percutaneous vascular interventions via radial or ulnar artery access at Mersin Medical Park Hospital will be consecutively enrolled. Demographic, clinical, angiographic, procedural, and post-procedural data will be prospectively collected and analyzed.
The study was initially designed as a single-center registry; however, following Institutional Review Board (IRB) approval, expansion into a multicenter registry with participating centers is planned.
This study is observational in nature and does not involve any experimental treatment, device, or intervention beyond standard clinical care.

Cohort
Prospective
Radial and Ulnar Artery Access
Procedure/SurgeryRoutine percutaneous vascular interventions performed via radial or ulnar artery access according to standard clinical practice.
Radial Artery Occlusion Rate
Incidence of radial artery occlusion following percutaneous vascular interventions performed via radial artery access.
Access-Site Vascular Complication Rate
Incidence of vascular access-site complications including bleeding, hematoma, pseudoaneurysm, arterial dissection, and vascular injury.
Radial Artery Spasm Rate
Incidence of clinically significant radial artery spasm during or immediately after the procedure.
Procedural Success Rate
Successful completion of the planned vascular intervention using radial or ulnar artery access without crossover to alternative access.
Crossover Rate
Need for conversion from radial or ulnar access to another vascular access site during the procedure.
Bleeding Complications
Incidence of access-site or non-access-site bleeding complications following the procedure.
Fluoroscopy Time
Total fluoroscopy time during the procedure, measured in minutes.
