Symptoms of Carotid Stenosis
Carotid stenosis may not cause any symptoms. When carotid stenosis causes a TIA or stroke, symptoms may include:
- Weakness or paralysis of an arm and/or leg on one side of the body
- Loss of coordination or movement
- Confusion, dizziness, or fainting
- Loss of sensation in the face, an arm, or a leg
- Problems with speech or vision
People experiencing these symptoms should seek care immediately by calling 911.
NewYork-Presbyterian Hospital uses the following tests to diagnose carotid stenosis:
- Carotid ultrasound using a duplex scan, a noninvasive way to assess blood flow in the carotid arteries
- Magnetic resonance imaging or magnetic resonance angiography
- Computed tomography scan
- Angiography
