1. A maximum intensity projection (MIP) image reconstructed from CT-angiographic data shows the high-grade stenosis of the right ICA as well as associated calcified atherosclerotic plaques (A).
A maximum intensity projection (MIP) image reconstructed from CT-angiographic data shows the high-grade stenosis of the right ICA as well as associated calcified atherosclerotic plaques (A). Digital subtraction angiography of the right carotid bifurcation before and after the intervention shows a tight, short-segment, hemodynamically significant stenosis (B, closed arrow)—note the low attenuation of contrast medium in ICA distal to the stenosis (B, open arrow)—and a good hemodynamic result after stent-placement and dilation (C).
