Fig. 5: Cross-sectional HF-OCT images compared to corresponding CBCT slices.

a A side-branch thrombosis is visible on the HF-OCT image (arrow). b Flow-diverter malapposition with a maximum severity of ~400 µm is visible on the HF-OCT image between 1 and 8 o’clock. Small thrombus formations over the flow-diverter struts, with a thickness between ~30 and 220 µm, are indicated by the arrowheads. The presence of thrombus and device malapposition are often undetected on the corresponding cone beam CT images. c Thrombosis on the ostium of a large side-branch. HF-OCT comparison with CBCT was repeated for all swine internal maxillary arteries (n = 16), following flow-diverting (n = 16), and self-expanding intracranial stent implantation (n = 15). Scale bars on HF-OCT images are equal to 1 mm. The star symbol (*) on CT images denotes the location of side-branches.
