It is common to see contrast opacification of the distal segment from retrograde filling from collaterals. The thrombus in the occluded segment of the artery commonly has low density and may contain calcified atheromas. Although the age of the thrombus in a patient without an acute coronary syndrome usually cannot be ascertained, these are commonly referred to as chronic total occlusions. It may be challenging with CT to differentiate a subtotal from a total occlusion. In the subtotal occlusion, the transition zone is typically shorter, and a small channel of contrast density is identified.
1A and B). Diagnosis The diagnosis is noncalcified plaque in the proximal LAD, with preserved arterial lumen. Discussion Positive remodeling is an outward compensatory remodeling (the Glagov phenomenon) in which the arterial wall bulges outward and the lumen remains uncompromised. Such plaques grow further, although they usually do not cause angina because they do not become hemodynamically significant for a long time. In fact, the plaque does not begin to encroach on the lumen until it occupies 40% of the cross-sectional area.
