The determination to request a carotid ultrasound during a patient’s hospital admission stems from the need to assess the carotid arteries, major blood vessels in the neck that supply blood to the brain. Evaluation via ultrasound aims to identify potential blockages or narrowing (stenosis) within these arteries. Detection of carotid artery disease is critical because significant stenosis increases the risk of stroke. The procedure uses sound waves to create an image of the arteries, allowing physicians to visualize blood flow and any abnormalities present.
Identifying carotid artery disease is of paramount importance in stroke prevention. Undiagnosed, significant stenosis can lead to thromboembolic events, where plaques or clots dislodge from the carotid arteries and travel to the brain, obstructing blood flow. Early detection enables timely intervention, which can include medical management with antiplatelet medications or surgical procedures such as carotid endarterectomy or carotid stenting. These interventions are proven to substantially reduce the risk of stroke in patients with significant carotid artery stenosis. Furthermore, performing this assessment during inpatient admission provides an opportunity to coordinate care seamlessly and initiate treatment promptly.
