Transradial access for renal artery intervention.

Area of Science:

• Cardiovascular Interventions
• Vascular Surgery
• Interventional Radiology

Background:

• Renal artery interventions traditionally utilize femoral or brachial vascular access.
• The transradial approach is gaining popularity for peripheral interventions, yet data for renal artery procedures is limited.

Purpose of the Study:

• To evaluate the clinical, angiographic, and technical outcomes of renal artery stenting performed via transradial access.
• To assess the feasibility and safety of the transradial approach for renal artery angioplasty and stenting.

Main Methods:

• Retrospective analysis of 27 patients undergoing renal artery stenting between 2012 and 2013.
• Procedures were performed using radial artery access, with guidewire passage, angioplasty, and stent implantation.
• Radial artery anatomy was confirmed via aortography prior to intervention.

Main Results:

• Successful renal artery stenting in all 27 patients (mean age 65.4 years) with significant stenosis.
• Primary technical success (residual stenosis <30%) achieved in all cases.
• Low complication rate, including one transient creatinine elevation and one asymptomatic radial artery occlusion.

Conclusions:

• Transradial renal artery angioplasty and stenting is a technically feasible and safe procedure.
• This approach demonstrates high success rates and a favorable safety profile for treating renal artery stenosis.
