Figure 2

Shows a conceptualized drawing of “near occlusion” as a collapsed lumen beyond very severe stenosis with flow reduction associated with presumed physiological loss of diameter of the distal ICA. NASCET recognized that any % stenosis calculation from such a reduced distal ICA lumen was flawed. Figure 2 is a reproduced part of a figure in Stroke (1). “Promotional and commercial use of the material in print, digital or mobile device format is prohibited without the permission from the publisher Lippincott Williams & Wilkins.
