Summary
Transradial access (TRA) is a safe and effective interventional technique. This study shows TRA offers improved patient experience and departmental efficiency with minimal complications.
Area of Science:
- Interventional Radiology
- Vascular Access Techniques
- Patient Outcomes
Background:
- Transradial access (TRA) is an alternative to traditional transfemoral approaches for endovascular procedures.
- Evaluating the safety and efficacy of TRA is crucial for optimizing patient care and departmental workflow.
Purpose of the Study:
- To detail a single center's technical methodology for transradial interventions.
- To report on the clinical outcomes and safety profile of transradial access procedures.
Main Methods:
- A retrospective analysis of 749 transradial access (TRA) procedures in 562 patients.
- Procedures included liver embolization, uterine artery embolization, and Selective Internal Radiation Therapy (Y90).
- Patient demographics and procedural details were collected.
Main Results:
- A very low crossover rate (0.5%) to transfemoral access was observed.
- Complication rates were minimal, including one radial artery occlusion (0.3%) and minor hematomas (0.4%).
- 98% of patients preferred radial access for future procedures over previous femoral access.
Conclusions:
- Transradial access is a safe and effective method for various interventional procedures.
- While a learning curve exists, TRA demonstrates potential for significant improvements in departmental efficiency and cost savings.
- Patient experience is positively impacted by the transradial approach.
