Atherosclerotic renal artery stenosis: current status

Area of Science:

• Nephrology
• Cardiology
• Hypertension

Background:

• Atherosclerotic renal artery stenosis (ARAS) is a significant cause of secondary hypertension and progressive kidney failure.
• Despite optimal medical management and blood pressure control, ARAS patients often experience persistent renal and systemic complications.
• The underlying mechanisms, precise diagnostic methods, and ideal treatment strategies for ARAS require further elucidation.

Purpose of the Study:

• To review current clinical trial outcomes and pathogenic mechanisms of ARAS.
• To discuss novel imaging modalities for assessing renal damage in ARAS.
• To explore current and future treatment options for ARAS.

Main Methods:

• Review of recent randomized prospective trials in ARAS management.
• Analysis of current scientific understanding of ARAS pathogenesis.
• Evaluation of emerging imaging techniques for kidney damage assessment.
• Synthesis of available and investigational treatment strategies.

Main Results:

• Medical therapy is the cornerstone of ARAS treatment, as supported by clinical trials.
• Significant gaps remain in understanding ARAS mechanisms, detection, and optimal therapeutic targets.
• Novel imaging techniques offer potential for improved assessment of kidney injury in ARAS.
• Early detection and targeted interventions are crucial for preventing adverse clinical outcomes.

Conclusions:

• ARAS necessitates comprehensive management beyond blood pressure control.
• Further research into pathogenic pathways and advanced imaging is essential for improving ARAS patient outcomes.
• Developing targeted strategies for early detection and treatment is critical to mitigate the complications of ARAS.
