Carotid duplex

Carotid duplex is an ultrasound procedure performed to assess blood flow through the carotid artery to the brain. High-frequency sound waves are directed from a hand-held transducer probe to the area. These waves bounce off the arterial structures and produce a 2-dimensional image on a monitor, which will make obstructions or narrowing of the arteries visible.

Carotid duplex ultrasound

This duplex Doppler sonogram shows an irregular plaque in the carotid artery. This type of plaque can cause clots to form, which can cause a stroke. Doppler studies are used to help identify these types of plaques ahead of time to prevent a stroke from happening.

Atherosclerosis of internal carotid artery

The build-up of plaque in the internal carotid artery may lead to narrowing and irregularity of the artery's lumen, preventing proper blood flow to the brain. More commonly, as the narrowing worsens, pieces of plaque in the internal carotid artery can break free, travel to the brain and block blood vessels that supply blood to the brain. This leads to stroke, with possible paralysis or other deficits.

Carotid artery anatomy

There are four carotid arteries, two on each side of the neck: right and left internal carotid arteries, and right and left external carotid arteries. The carotid arteries deliver oxygen-rich blood from the heart to the head and brain.
