Video 2. Optical coherence tomography (OCT) scan. For lower risk of iatrogenic ischemia, we used non-occlusive techniques that flushed contrast media to displace the blood. In the first 13 mm and 43 to 55 mm of the scan, incomplete replacement of blood caused interference of the infrared light. In the 15 mm, there were white thrombi and concentric intimal thickening. Between 25 and 30 mm, we found aneurysm with uneven edge, irregular thickening and absent border of the intima and media layer. In 35 mm, there was mild narrowing of the lumen, which showed eccentric intimal thickening. In 43 to 55 mm, in the mid-portion of the giant aneurysm, because of incomplete replacement of blood and lower depth of OCT image, the details could not be presented clearly.
