Arterial spin-labeling cerebral perfusion changes after revascularization surgery in pediatric moyamoya disease and syndrome.

J Neurosurg Pediatr 2019 Feb 8:1-7. Epub 2019 Feb 8.

4Division of Pediatric Neuroradiology, Department of Radiology, Lucile Packard Children's Hospital, Stanford University School of Medicine, Stanford, California.

OBJECTIVEMoyamoya disease is a dynamic cerebrovascular condition that often requires vascular surveillance. Arterial spin labeling (ASL) is an MR perfusion method that is increasingly used for stroke and other various neurovascular pathologies. Unlike perfusion-weighted MRI, ASL uses endogenous water molecules for signal and therefore obviates gadolinium use; and provides direct, not relative, quantitative cerebral blood flow (CBF) measures.

Spontaneous bilateral internal carotid and vertebral artery dissections with dominant-hemisphere circulation maintained by external carotid artery-ophthalmic artery anastomoses.

Neurosurg Focus 2019 Feb;46(2):E6

3Department of Radiology, and.

Spontaneous cervical artery dissection (sCAD) is a major cause of stroke in young adults. Multiple sCAD is a rarer, more poorly understood presentation of sCAD that has been increasingly attributed to cervical trauma such as spinal manipulation or genetic polymorphisms in extracellular matrix components. The authors present the case of a 49-year-old, otherwise healthy woman, who over the course of 2 weeks developed progressive, hemodynamically significant, bilateral internal carotid artery and vertebral artery dissections.

Association Between Net Vertebral Artery Flow Volume and Non-AF Stroke: A Retrospective 2-Year Analysis.

Front Neurol 2018 18;9:1198. Epub 2019 Jan 18.

Department of Neurology, Taipei Medical University-Shuang Ho Hospital, New Taipei City, Taiwan.

Association between net vertebral artery flow volume (NVAFV) and stroke types remains unclear. We hypothesize NVAFV is low in patients with posterior circulation infarction (PCI) and an ideal cut-off value for discriminating PCI from anterior circulation infarction (ACI) and controls may be present. As study candidates, we retrospectively enrolled hospitalized patients with first-time non-AF stroke within 2-years period. Read More

The intravenous infusion of mesenchymal stem cells (MSCs) elicits therapeutic efficacy in experimental supratentorial stroke models. However, since there are few reliable animal models of ischemia in the posterior circulation, the therapeutic approach with intravenous MSC infusion has not been tested. Read More

Clinical-radiographic correlates of Artery of Percheron infarcts in a case series of 6 patients.

J Clin Neurosci 2019 Mar 22;61:266-268. Epub 2018 Nov 22.

Department of Neurology, NYU Langone Medical Center, NY, United States.

Bilateral thalamic strokes due to Artery of Percheron (AOP) occlusion are rare but have been previously reported in the literature. It is due to a rare anatomic variant where a solitary arterial trunk from the proximal segment of either posterior cerebral artery (PCA) supplies bilateral thalami and midbrain. Despite its description in the literature, these strokes are usually missed and patient's symptoms are not thought to be secondary to a vascular etiology. Read More

Constrained-induced movement therapy promotes motor function recovery by enhancing the remodeling of ipsilesional corticospinal tract in rats after stroke.

Brain Res 2019 Apr 22;1708:27-35. Epub 2018 Nov 22.

Department of Rehabilitation Medicine, Huashan Hospital, Fudan University, Shanghai, China. Electronic address:

Constraint-induced movement therapy (CIMT), which forces the use of the impaired limb by restraining the unaffected limb, has been used extensively for the recovery of limb motor function after stroke. However, the underlying mechanism of CIMT remains unclear. Diffusion tensor imaging (DTI) is a well-known neuroimaging technique that reflects the microstructure of white matter tracts and potential changes associated with different treatments. Read More

Transcranial color-coded sonography findings of patients with reversible cerebral vasoconstriction syndromes.

J Clin Neurosci 2019 Mar 22;61:290-292. Epub 2018 Nov 22.

Department of Neurology, Jikei University School of Medicine, Japan.

Reversible cerebral vasoconstriction syndromes (RCVS) have been well recognized recently as one cause of cerebrovascular disease, but the time course of vessel vasoconstriction remains uncertain. We report herein 2 cases with RCVS in which we clarified temporal changes in vessel vasoconstriction in detail using transcranial color-coded sonography (TCCS). The first case involved a 27-year-old woman who developed intracerebral hemorrhage (ICH) and subarachnoid hemorrhage (SAH) after severe headache. Read More

Fetal stroke and cerebrovascular disease: Advances in understanding from lenticulostriate and venous imaging, alloimmune thrombocytopaenia and monochorionic twins.

Eur J Paediatr Neurol 2018 Nov 11;22(6):989-1005. Epub 2018 Sep 11.

Departments of Child Health, Obstetrics and Gynaecology and Radiology, University Hospital Southampton, United Kingdom; Clinical and Experimental Sciences, University of Southampton, United Kingdom.

Fetal stroke is an important cause of cerebral palsy but is difficult to diagnose unless imaging is undertaken in pregnancies at risk because of known maternal or fetal disorders. Fetal ultrasound or magnetic resonance imaging may show haemorrhage or ischaemic lesions including multicystic encephalomalacia and focal porencephaly. Serial imaging has shown the development of malformations including schizencephaly and polymicrogyra after ischaemic and haemorrhagic stroke. Read More

Interv Neuroradiol 2018 Nov 21:1591019918811802. Epub 2018 Nov 21.

1 Department of Radiology, University of British Columbia, Vancouver, Canada.

Distal emboli and emboli to new territories occur in up to 14% and 11% of large vessel occlusion mechanical thrombectomies, respectively. A retrospective review was conducted of 18 consecutive patients with large vessel occlusion acute stroke undergoing mechanical thrombecomy, subsequently developing distal emboli and/or emboli to new territory for which thromboaspiration using the 3MAX catheter was performed. Eighteen distal emboli and two emboli to new territory in 18 patients were treated in the distal M2 and M3 middle cerebral artery, pericallosal and callosomarginal arteries, and P2 posterior cerebral artery (all arteries ≥1.

Differential regional infarction, neuronal loss and gliosis in the gerbil cerebral hemisphere following 30 min of unilateral common carotid artery occlusion.

Metab Brain Dis 2019 02 15;34(1):223-233. Epub 2018 Nov 15.

Department of Biomedical Science and Research Institute for Bioscience and Biotechnology, Hallym University, Chuncheon, Gangwon, 24252, Republic of Korea.

The degree of transient ischemic damage in the cerebral hemisphere is different according to duration of transient ischemia and cerebral regions. Mongolian gerbils show various lesions in the hemisphere after transient unilateral occlusion of the common carotid artery (UOCCA) because they have different types of patterns of anterior and posterior communicating arteries. We examined differential regional damage in the ipsilateral hemisphere of the gerbil after 30 min of UOCCA by using 2,3,5-triphenyltetrazolium chloride (TTC) staining, cresyl violet (CV) Nissl staining, Fluoro-Jade B (F-J B) fluorescence staining, and NeuN immunohistochemistry 5 days after UOCCA.

Influence of the circle of Willis on leptomeningeal collateral flow in anterior circulation occlusive stroke: Friend or foe?

J Neurol Sci 2019 Jan 3;396:69-75. Epub 2018 Nov 3.

Department of Neurology, Christian Doppler Medical Center, Paracelsus Medical University, Salzburg, Austria. Electronic address:

Background: Clinical outcome after large vessel occlusion (LVO) stroke depends on collateral integrity. We aimed to evaluate whether the completeness of the circle of Willis (CoW) and anterior temporal artery (ATA) determines the status of leptomeningeal collaterals (LC) in patients with acute LVO (internal carotid artery (ICA) and middle cerebral artery M1 (MCA) occlusion) treated with endovascular thrombectomy.

Patients And Methods: LC, cross-flow through the anterior communicating artery (ACoA), presence of the ipsilateral posterior communicating artery (IpsiPCoA) and presence of the ATA were evaluated using CT angiography. Read More
