Summary
Transradial renal artery angioplasty and stenting is a safe and feasible technique. This approach offers an attractive alternative for patients with challenging renal artery anatomy, improving blood pressure and kidney function.
Area of Science:
- Cardiovascular Medicine
- Interventional Radiology
- Nephrology
Background:
- Renal artery stenosis (RAS) management typically involves femoral or brachial access.
- The transradial approach is well-established for coronary interventions but less explored for renal arteries.
Purpose of the Study:
- To evaluate the feasibility and safety of the transradial approach for renal artery angioplasty and stenting.
- To assess clinical outcomes, including blood pressure and renal function, in patients undergoing transradial renal artery intervention.
Main Methods:
- 18 patients with unilateral RAS underwent transradial renal artery angioplasty and stenting.
- Indications included acute aorto-renal angles or severe peripheral arterial obstructions.
- Procedures involved guiding catheter engagement, guidewire passage, and stent implantation.
Main Results:
- Successful stent implantation was achieved in all cases (16 direct, 2 post-dilated).
- Primary technical success (residual stenosis < 30%) was 100%.
- No periprocedural complications occurred; access site arteries showed normal perfusion.
Conclusions:
- Transradial renal artery angioplasty and stenting is technically feasible and safe.
- This cranio-caudal approach is a valuable alternative, especially for patients with unfavorable anatomy.
- Significant improvements in blood pressure control and serum creatinine levels were observed.
