Therefore, we conducted the present study to revisit duplex ultrasound criteria for determining normal (0-< 30% stenosis) versus abnormal (= 30%) in-stent carotid restenosis.

Carotid Artery Ultrasound Doppler Scan - This is a noninvasive diagnostic test that uses ultrasound to detect narrowing of the arteries in the neck and can estimate the degree of narrowing or ...

When plaque forms in these arteries, the arteries can become narrow, called carotid artery stenosis ... Carotid duplex ultrasound – This test uses sound waves to create pictures.

Sixty-three percent were done for ≥ 70% asymptomatic carotid stenosis and 37% for strokes/transient ischemic attacks. Table 1 summarizes the clinical and demographic characteristics. The ...
