Cerebral foreign body reaction due to hydrophilic polymer embolization following aneurysm treatment by pipeline flow diversion device.

Interv Neuroradiol 2019 Mar 28:1591019919830767. Epub 2019 Mar 28.

2 Stanford Hospital and Clinics, Stanford, USA.

The use of flow diverting stents for wide based, intracranial aneurysms has become an invaluable treatment option. While intracranial hemorrhage and ischemic stroke from dislodged atherosclerotic emboli are common adverse events, the potential for delayed granulomatous inflammation from possible hydrophilic polymer emboli is rarely recognized. We present a unique case in which visible chipping of the pusher wire for stent placement was observed, followed by clinical and radiographic evidence suggestive of a delayed foreign body reaction to intracranial hydrophilic polymer emboli.

Misery perfusion and amyloid deposition in atherosclerotic major cerebral artery disease.

Neuroimage Clin 2019 Mar 12;22:101762. Epub 2019 Mar 12.

Division of PET Imaging, Shiga Medical Centre Research Institute, Moriyama, Japan; National Institute of Radiological Sciences, National Institutes of Quantum and Radiological Science and Technology, Chiba, Japan.

Although experimental studies have shown that global cerebral hypoperfusion leads to amyloid deposition in the hemisphere with carotid artery occlusion in rodents, the results of such occurrence are controversial in humans. Hence, we aim to determine whether global cerebral hypoperfusion leading to decreased blood flow relative to metabolic demand [increased oxygen extraction fraction (OEF), misery perfusion] is associated with increases in amyloid deposition in the hemisphere with atherosclerotic major cerebral artery disease in patients. We evaluated the distribution of β-amyloid plaques using positron emission tomography and a [18F]-pyridylbenzofuran derivative (F-FPYBF-2) in 13 patients with unilateral atherosclerotic disease of the internal carotid artery (ICA) or middle cerebral artery (MCA) disease and no cortical infarction.

Front Neurol 2019 18;10:72. Epub 2019 Feb 18.

Department of Biomedical Engineering, University of Utah, Salt Lake City, UT, United States.

Improved understanding of neuroimaging signal changes and their relation to patient outcomes after ischemic stroke is needed to improve ability to predict motor improvement and make therapy recommendations. The posterior limb of the internal capsule (PLIC) is a hub of afferent and efferent motor signaling and this work proposes new, image-based methods for prognosis based on interhemispheric differences in the PLIC. In this work, nine acute supratentorial ischemic stroke patients with motor impairment received a baseline, 203-direction diffusion brain MRI and a clinical assessment 3-12 days post-stroke and were compared to nine age-matched healthy controls.

We herein showcase a confirmed case of the Percheron infarction at the admission day, in which the patient advanced into severe multiple posterior circulation infarcts, along with petechial hemorrhage within the infarcts, even given the right therapy without delay. It reminds us that whether we could or should take this special infarction as a forewarning of more harmful infarcts getting in the way, or at least a precaution of poor vessel condition. Read More

J Neurosurg 2019 Jan 11:1-8. Epub 2019 Jan 11.

Departments of1Neurosurgery and.

OBJECTIVEWith the increasing use of flow diversion as treatment for intracranial aneurysms, there is a concomitant increased vigilance in monitoring complications. The low porosity of flow diverters is concerning when the origins of vessels are covered, whether large circle of Willis branches or critical perforators. In this study, the authors report their experience with flow diverter coverage of the lenticulostriate vessels and evaluate their safety and outcomes. Read More

Identifying Hypoperfusion in Moyamoya Disease With Arterial Spin Labeling and an [O]-Water Positron Emission Tomography/Magnetic Resonance Imaging Normative Database.

Stroke 2019 Feb;50(2):373-380

From the Department of Radiology (A.P.F., J.G., Y.I., J.R., M.W., J.H.P., B.S., D.H., H.G., T.H., P.S., F.T.C., G.Z.), Stanford University, CA.

Background and Purpose- Noninvasive imaging of brain perfusion has the potential to elucidate pathophysiological mechanisms underlying Moyamoya disease and enable clinical imaging of cerebral blood flow (CBF) to select revascularization therapies for patients. We used hybrid positron emission tomography (PET)/magnetic resonance imaging (MRI) technology to characterize the distribution of hypoperfusion in Moyamoya disease and its relationship to vessel stenosis severity, through comparisons with a normative perfusion database of healthy controls. Methods- To image CBF, we acquired [O]-water PET as a reference and simultaneously acquired arterial spin labeling (ASL) MRI scans in 20 Moyamoya patients and 15 age-matched, healthy controls on a PET/MRI scanner.

Stent-assisted coil embolization of MCA aneurysm via a trans-posterior communicating artery access.

Neurosurg Focus 2019 Jan;46(Suppl_1):V3

3Cerebrovascular Neurosurgery and Comprehensive Stroke Center, Chicago, Illinois.

External carotid artery (ECA) to internal carotid artery (ICA) bypass is a well-established procedure for the treatment of chronic ischemic diseases of the carotid artery. Rarely de novo aneurysms can develop at the site of anastomosis. The treatment of these aneurysms can be very challenging due to various factors, including the presence of graft, previous craniotomy, atherosclerotic vessels, and lack of direct access. Read More

Compression Syndromes of the Vertebral Artery at the Craniocervical Junction.

Acta Neurochir Suppl 2019;125:151-158

Service de neurochirurgie, CHU, Strasbourg, France.

Compression syndromes of the vertebral artery that occur at the craniocervical junction are extremely rare causes of haemodynamic insufficiency of the posterior cerebral circulation. The aetiology of the compression syndrome may be a malformation, trauma, tumour, infection or degenerative pathology. This may lead to dynamic vertebral artery occlusion where the vessel courses around the atlas and the axis-the so-called V3 segment. Read More
