Recanalization of organized thrombi (ROT) is a rarely recognized disease histologically characterized by older coronary thrombi forming small lumens or endothelium-lined neovascular channels within thrombus. Optical coherence tomography (OCT) is the method of choice for diagnosis and shows signal-rich, high backscattered septa dividing the lumen into multiple small channels that communicate with each other (1). Computed tomography angiography (CTA) in the longitudinal and cross-sectional planes may demonstrate the ROT by showing multiple small contrast-filled spaces divided by low-attenuation septa in agreement with the OCT findings (Figures 1 and 2). Given its rarity, CTA findings of ROT have not been well characterized. In this pictorial essay, we highlight the potential utility of CTA as a noninvasive imaging modality in the diagnosis of ROT. In addition, we provide CTA-OCT demonstration of spontaneous dissection (Figure 3) and thrombus by plaque rupture (Figure 4), which should be included in the differential diagnosis of ROT.
