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… Expand

Endovascular optical coherence tomography imaging in cerebrovascular disease
Endovascular OCT appears to be safe and feasible, allowing clinicians to visualize stent-vessel interactions, aneurysmal healing, and vulnerable atherosclerotic plaque features, however additional investigations are needed before any imposing statement can be made about the role of OCT in cerebrovascular imaging.

Optical Coherence Tomography for Neurovascular Disorders
This technology is reviewed and the rationale for utilization of OCT in the cerebrovasculature is presented to present the promise for eventual translation of OCT into the clinical arena. Expand
Up around the bend: progress and promise of intravascular imaging in neurointerventional surgery
Using intravascular imaging, with nearly microscopic resolution, vascular pathologies can now be accurately diagnosed in vivo in a manner similar to pathological studies, leading to clearer insights into the materials and techniques used in neurointerventional surgery. Expand
Endovascular Cerebral Venous Sinus Imaging with Optical Coherence Tomography

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. Expand
Evaluation of cerebral artery perforators and the pipeline embolization device using optical coherence tomography
The first use of a commercial OCT catheter in the evaluation of intracranial vessels using transfemoral endovascular techniques is described and may aid in the diagnosis and treatment of cerebrovascular disease in the future. Expand
Intravascular frequency-domain optical coherence tomography assessment of carotid artery disease in symptomatic and asymptomatic patients.
This retrospective analysis ofcarotid OCT data supports the hypothesis that the evaluation of carotid plaque characteristics with this high-resolution imaging technique has the potential to alter the understanding and treatment of carOTid artery disease. Expand
Collar Sign in Incompletely Occluded Aneurysms after Pipeline Embolization: Evaluation with Angiography and Optical Coherence Tomography
The collar sign appears to be indicative of endothelialization, but continued blood flow into the aneurysm after treatment with the Pipeline Embolization Device and has not been previously reported. Expand
Optical coherence tomography after carotid stenting: rate of stent malapposition, plaque prolapse and fibrous cap rupture according to stent design.
Intravascular OCT after CAS revealed that micro-defects after stent deployment are frequent and are related to the design of implanted stents, while stent malapposition is more frequent with CC stent, while plaque prolapse is more common with OC stents. Expand
Intravascular imaging in coronary artery disease
Intravascular imaging-intravascular ultrasound and more recently optical coherence tomography-provide a tomographical or cross-sectional image of the coronary arteries to answer questions such as whether the stenosis is clinically relevant; the identification of the culprit lesion; or whether the plaque is at high risk of future adverse events.
