Renal artery stenosis (RAS) is common in older adults. Careful diagnosis is crucial before intervention, as not all patients benefit from revascularization, and procedures carry risks.
Area of Science:
- Cardiovascular Medicine
- Nephrology
- Interventional Radiology
Context:
- Renal artery stenosis (RAS) is a prevalent and progressive condition, particularly in patients over 65, with reported frequencies of 11-23% in those undergoing coronary angiography.
- Despite its prevalence, the benefits of renal artery revascularization for reducing cardiovascular and renal events remain debated, with up to 40% of patients not experiencing positive outcomes.
Purpose:
- To emphasize the necessity of comprehensive diagnostic work-ups for renal artery stenosis (RAS) prior to intervention.
- To highlight the importance of integrating both morphological and functional tests for accurate patient selection.
Summary:
- Morphological evaluation can be performed using multislice computed tomography, magnetic resonance tomography, or digital subtraction angiography.
- Functional assessment, crucial for determining physiological significance, can be achieved through Doppler ultrasound or invasive pressure and flow measurements.
- The long-term predictive value of these diagnostic methods requires further assessment.
Impact:
- Percutaneous intervention for RAS, while less risky than surgery, carries risks of renal function deterioration and procedure-dependent complications due to contrast media.
- A thorough consideration of the pros and cons of renal artery revascularization is mandatory for optimal patient management.
