Safety and Feasibility of Transradial Infrainguinal Peripheral Arterial Disease Interventions

Initial experience with transradial access for cerebrovascular procedures: is it feasible and safe?
Despite the proven benefit of transradial access over transfemoral access in cardiac procedures, the transition for cerebrovascular procedures has only been slowly enforced. Here we present our experience with transradial access in cerebral diagnostic angiographies and neurointerventional procedures.
Single-Center Retrospective Comparative Analysis of Transradial, Transbrachial, and Transfemoral Approach for Mesenteric Arterial Procedures

Transradial Access for Neurointerventions: Management of Access Challenges and Complications
Numerous large randomized trials have shown a significant morbidity and mortality benefit with the transradial approach (TRA) over the transfemoral approach (TFA) for endovascular procedures. However, this technique is routinely avoided or aborted due to unfamiliarity with the technique and the associated anatomical difficulties that may be faced in this approach. The objective of this review is to identify both the common and uncommon challenges that may be encountered during a transradial approach for cerebrovascular catheterization and to provide tips and tricks to overcome the transradial learning curve.
Expedited TR Band Removal for Transradial Approach for Noncoronary Visceral Procedures: Initial Experience.
For transradial interventions, most published studies report an initial Terumo Radial (TR) band placement time of 60 minutes, with gradual deflation over 30 to 90 minutes. We aimed to determine, retrospectively, whether TR band removal time could be expedited to 45 to 60 minutes, without adverse effects via an expedited single-step deflation protocol.
Transitioning to Transradial Access for Cerebral Aneurysm Embolization
Despite several retrospective studies showing the safety and efficacy of transradial access for cerebral angiography, neurointerventionalists are apprehensive about implementing TRA for neurointerventions. This reluctance is mainly due to anatomic factors, technical factors, and a long learning curve (relative to transfemoral access). We present here our experience of TRA transition for cerebral aneurysm embolization. Our aim was to demonstrate the feasibility and safety of radial access for consecutive embolizations of ruptured and unruptured cerebral aneurysms.
Feasibility of repeat transradial access for neuroendovascular procedures
Transradial artery access (TRA) for cerebrovascular angiography is increasing due to decreased access site complications and overwhelming patient preference. While interventional cardiologists have reported up to 10 successive TRA procedures via the same radial access site, this is the first study examining successive use of the same artery for repeat procedures in neurointerventional procedures.
Distal Transradial Access in the Anatomic Snuffbox for Diagnostic Cerebral Angiography
The aim of this study was to describe the feasibility, technique, and safety of distal transradial access in the anatomic snuffbox for diagnostic cerebral angiography. A retrospective review of diagnostic cerebral angiograms obtained during a 6-month period with distal transradial access was performed. Thirty-four successful procedures were performed via distal transradial access. There were 4 failed attempts. This single-center experience using distal transradial access suggests that this technique is safe and effective.

Radical Radial: Pearls and Pitfalls in Transradial Yttrium-90 Liver-Directed Therapy
The frequency of transradial access in interventional radiology has been steadily increasing, including for yttrium-90 (Y-90) selective internal radiation therapy to treat hepatic malignancies. The aim of this article is to detail an optimized approach to transradial Y-90 (TRY-90), showing it to be a safe and feasible first-line approach to hepatic selective internal radiation therapy. Salient preprocedural considerations to enable appropriate patient selection for TRY-90 are discussed and a detailed equipment list is provided. The article will describe our approach to TRY-90 in addition to a discussion around technical pearls and pitfalls.
