    1. Frequency-Domain Optical Coherence Tomography for Intracranial Atherosclerotic Stenosis: Feasibility, Safety, and Preliminary Experience

      Frequency-Domain Optical Coherence Tomography for Intracranial Atherosclerotic Stenosis: Feasibility, Safety, and Preliminary Experience

      Background: Despite advances in non-invasive imaging, the characterization of atherosclerotic plaque remains superior with frequency-domain optical coherence tomography (FD-OCT) in the clinical coronary and experimental cerebrovascular literature. An assessment of the feasibility and safety of FD-OCT for intracranial atherosclerotic stenosis (ICAS) is desirable. Methods: We analyzed a cohort of all consecutive FD-OCT evaluations for ICAS performed at our institution from April 2017 to August 2018 (16 months) in patients who suffered from transient ischemic attack (TIA) or non-disabling stroke despite optimal medical management within 90 days of admission attributable to angiographically verified 70-99% stenosis of an intracranial artery. Results: Thirty-three ...

    2. Neovascularization in Human Intracranial Atherosclerotic In-Stent Restenosis

      Neovascularization in Human Intracranial Atherosclerotic In-Stent Restenosis

      Optical coherence tomography (OCT) has seen widespread use in cardiovascular and interventional endovascular imaging. While scattered reports of intracranial usage have been reported for the assessment of atherosclerotic stenosis, nutrifying neovasculature supplying plaque and neointima have not been demonstrated until now. We report the first in-vivo illustration of this phenomenon, which is a high-resolution depiction of a critical pathway for in-stent restenosis.

    3. Visualization of the Human Intracranial Vasa Vasorum In Vivo Using Optical Coherence Tomography

      Visualization of the Human Intracranial Vasa Vasorum In Vivo Using Optical Coherence Tomography

      The vasa vasorum are a specialized microvasculature that mainly arise from the adventitia and traverse the intimomedial layer of large arteries and veins. These are felt to serve as crucial routes of the delivery for trophic and nutritive factors, as well as regulatory signals. 1 Importantly, they also play a role in pathology via proliferation in atherosclerotic and hypertrophic intimomedia, as well as plaque hemorrhage and dissection via rupture. 2 In the setting of symptomatic vertebral artery stenosis, we report what is, to our knowledge, the first known in vivo visualization of the human native intracranial arterial vasa vasorum and ...
