Renal artery stenosis is a narrowing of one or both renal arteries, commonly caused by atherosclerosis or fibromuscular dysplasia. This condition restricts blood flow to the kidneys, potentially leading to hypertension and kidney dysfunction. In medical diagnosis, identifying renal artery stenosis is crucial for managing patient cardiovascular health.
Ultrasound is a key non-invasive tool for detecting and assessing renal artery stenosis. Doppler ultrasound can visualize blood flow velocity and patterns within the renal arteries, revealing the characteristic high velocities and turbulence associated with the stenosis. Early and accurate ultrasound detection aids in timely intervention and improved patient outcomes.
