Background Intracranial vertebrobasilar artery stenosis is an important cause of ischemic stroke. With its high resolution, intravascular optical coherence tomography (OCT) provides detailed assessment of vessel wall features. It is widely applied to identify high-risk plaque in the cardiovascular system, but its use in the intracranial artery has been limited. Objective To explore, in this pilot study, the usefulness of OCT in imaging of the intracranial artery wall. Methods Between November…

Correlation between intracranial vertebral artery stenosis diameter measured by digital subtraction angiography and cross-sectional area measured by optical coherence tomography
Measurement of the narrowest diameter stenosis, measured by digital subtraction angiography (DSA), with the area stenosis (AS), measured by OCT, showed that only observer measurement using the oblique view and the WASID method could attain statistically significant differences, but it was weak.

Embedded stent struts, plaque prolapse, and fibrous cap rupture were more frequent and well-apposed stentstruts were less frequent after CAS in patients with lipid-rich plaque, which may be associated with acute stent thrombosis.
