Carotid Doppler ultrasound is frequently used to evaluate for stenosis when a patient presents with stroke-like symptoms. This article aims to increase awareness of various sonographic findings associated with less common scenarios encountered when interpreting carotid Doppler examinations, such as aortic stenosis, aortic insufficiency, cardiac assist devices, and carotid-internal jugular fistula. Ultimately, carotid Doppler ultrasound is a useful tool in diagnosis and subsequent management of a multitude of clinical scenarios that may be encountered when interpreting carotid ultrasounds.
