What is the clinical indication for performing a carotid ultrasound?

The clinical indication for performing a carotid ultrasound is primarily to evaluate for stenosis or occlusion in the carotid arteries. This procedure assesses the blood flow in the carotid arteries, which supply oxygen-rich blood to the brain. By detecting narrowing (stenosis) or blockages (occlusions), healthcare providers can identify risk factors for stroke or transient ischemic attacks (TIAs).

This evaluation is critical for developing a treatment plan to reduce the chances of cerebrovascular accidents. Carotid ultrasounds help visualize plaque buildup or other abnormalities in the arterial walls, providing vital information that can lead to early intervention or management of cardiovascular disease. This focus on the carotid arteries distinguishes it from imaging methods aimed at other areas, such as the heart, kidneys, or gallbladder, which have their specific protocols and indications.
