Abstract
In a prospective study, 65 consecutive patients with suspected symptomatic high grade ICA stenosis were examined during a 12 months period 1998±99. Using a Siemens Sonoline Elegra, Siemens Medical System, Washington, U.S.A., and an angle of insonation of below 60%, flow velocities within the common carotid artery (CCA) and the ICA were obtained bilaterally. The degree of stenosis was determined using a modification of the criterias developed by Zwiebel. Hence, a 70% stenosis was characterised by an ICA peak systolic velocity 150 cm sy1, an ICA end diastolic velocity 90 cm sy1, and a PSV ratio 4 2.8. No flow indicated occlusion. From selective carotid angiography the degree of stenosis was calculated using the NASCET method.
