The main focus of carotid duplex examination is to identify stenotic lesions within the carotid arteries. Significant carotid artery stenosis may lead to transient ischemic deficit(TIA), or stroke. Duplex examination is a reliable tool for assessing the degree of carotid stenosis. Carotid artery endarterectomy is often performed based on duplex findings only without confirmatory angiography. While the vast majority of hemodynamically significant lesions involve the carotid bifurcation and proximal ICA, carotid duplex examination includes the entire sonographically accessible carotid system, vertebral arteries, and often the subclavian arteries. Other pathology which can be encountered on Carotid Duplex includes: carotid artery dissection, and carotid body tumour. Ultrasound is well suited for long-term surveillance of minor carotid stenoses or post-endarterectomy patients.
