Which clinical scenario warrants evaluation of the carotid arteries?

• A. Uncontrolled hypertension with headaches
• B. Abdominal pain with constipation
• C. Ischemic stroke, TIA or neurologic symptoms referable to the carotid arteries
• D. Diabetes mellitus with microvascular complications

Answer: (C)

Evaluation of the carotid arteries is indicated when there are signs of cerebrovascular insufficiency, such as ischemic stroke, a transient ischemic attack, or neurologic symptoms that localize to the carotid/anteriore circulation. The carotids can harbor atherosclerotic plaque that leads to emboli or reduced blood flow to areas controlling language, movement, and vision. Identifying significant carotid stenosis in a symptomatic patient helps guide treatment, because procedures like carotid endarterectomy or stenting, alongside medical therapy, can reduce the risk of recurrent stroke. Scenarios like uncontrolled hypertension with headaches, abdominal pain with constipation, or diabetes with microvascular complications don’t directly point to carotid pathology, so carotid imaging isn’t the primary concern there.
