Arterial stenosis, a critical vascular condition in medical ultrasound, refers to the abnormal narrowing or constriction of an artery, impeding normal blood flow. This often results from atherosclerosis, where plaque buildup reduces the vessel lumen, leading to decreased oxygen supply to tissues. Early detection and assessment of arterial stenosis are crucial for preventing serious complications like heart attacks, strokes, or peripheral artery disease.
Ultrasound plays a vital role in diagnosing arterial stenosis by visualizing the degree of narrowing and evaluating blood flow dynamics using Doppler techniques. Accurate characterization of stenotic lesions through ultrasound helps clinicians determine the severity of the condition, guiding appropriate treatment strategies such as medication, angioplasty, or surgical intervention.
