Background
Pelvic conditions such as uterine fibroids and BPH were traditionally treated via femoral access. Similarly, lower extremity peripheral arterial disease is most commonly treated via femoral ‘up and over’ access. Radial access is valuable in patients with difficult aortic bifurcation anatomy or ‘hostile’ groins. Furthermore, the development of longer delivery systems has allowed radial access to be increasingly used as a primary access point for these interventions, even for infrapopliteal disease.

Educational Goals / Teaching Points
This exhibit aims to provide a brief overview of the technique and patient selection criteria for radial arterial access in interventional radiology; review a spectrum of indications for utilizing radial access in a variety of interventions, specifically for the treatment of pelvic and lower extremity peripheral arterial disease; and provide a case-based format to illustrate the above.

Key Anatomic/Physiologic Issues and Imaging Findings/Techniques
This exhibit includes a brief overview of technique and patient selection criteria for performing radial arterial access and review of potential indications for performing radial access for pelvic and lower extremity arterial intervention ( uterine artery embolization; prostate artery embolization; iliac artery intervention; infrainguinal peripheral arterial disease and beyond).

Conclusion
Radial arterial access is now commonly performed for a spectrum of interventional radiology procedures. Radial access can be especially useful for the treatment of pelvic disease and infrainguinal peripheral arterial disease, particularly in situations of difficult access or arterial angulation.
