Vertebral Artery Hypoplasia: Frequency and Effect on Cerebellar Blood Flow Characteristics.

Thierfelder KM1, Baumann AB, Sommer WH, Armbruster M, Opherk C, Janssen H, Reiser MF, Straube A, von Baumgarten L.Author information 1From the Department of Clinical Radiology (K.M.T., A.B.B., W.H.S., M.A., M.F.R.), Department of Neurology (C.O., A.S., L.v.B.), Institute for Stroke and Dementia Research (C.O.), and Department of Neuroradiology (H.J.), Ludwig-Maximilians-University of Munich Hospitals, Munich, Germany.AbstractBACKGROUND AND PURPOSE: Vertebral artery hypoplasia (VAH) is supposed to be a risk factor for posterior circulation ischemia (PCI), particularly in the territory of the posterior inferior cerebellar artery (PICA). The aim of our study was to determine whether VAH impedes perfusion in the dependent PICA territory even in the absence of manifest PCI.

Computational modelling of emboli travel trajectories in cerebral arteries: influence of microembolic particle size and density.

Fabbri D1, Long Q, Das S, Pinelli M.Author information 1Brunel Institute for Bioengineering, Brunel University, Uxbridge, Middlesex , UB8 3PH, UK.AbstractIschaemic stroke is responsible for up to 80 % of stroke cases. Prevention of the reoccurrence of ischaemic attack or stroke for patients who survived the first symptoms is the major treatment target. Accurate diagnosis of the emboli source for a specific infarction lesion is very important for a better treatment for the patient. However, due to the complex blood flow patterns in the cerebral arterial network, little is known so far of the embolic particle flow trajectory and its behaviour in such a complex flow field. The present study aims to study the trajectories of embolic particles released from carotid arteries and basilar artery in a cerebral arterial network and the influence of particle size, mass and release location to the particle distributions, by computational modelling. The cerebral arterial network model, which includes major arteries in the circle of Willis and several generations of branches from them, was generated from MRI images. Particles with diameters of 200, 500 and 800 [Formula: see text] and densities of 800, 1,030 and 1,300 [Formula: see text] were released in the vessel's central and near-wall regions. A fully coupled scheme of particle and blood flow in a computational fluid dynamics software ANASYS CFX 13 was used in the simulations. The results show that heavy particles (density large than blood or a diameter larger than 500 [Formula: see text]) normally have small travel speeds in arteries; larger or lighter embolic particles are more likely to travel to large branches in cerebral arteries. In certain cases, all large particles go to the middle cerebral arteries; large particles with higher travel speeds in large arteries are likely to travel at more complex and tortuous trajectories; emboli raised from the basilar artery will only exit the model from branches of basilar artery and posterior cerebral arteries. A modified Circle of Willis configuration can have significant influence on particle distributions. The local branch patterns of internal carotid artery to middle cerebral artery and anterior communicating artery can have large impact on such distributions.

Double embolic protection during carotid artery stenting with persistent hypoglossal artery.

Silva CF1, Hou SY, Kühn AL, Whitten RH, Wakhloo AK.Author information 1Department of Radiology, Division Neuroimaging and Intervention, New England Center for Stroke Research, Worcester, Massachusetts, USA.AbstractA woman presented with 75% stenosis of the right internal carotid artery (ICA) with extension to the origin of a persistent hypoglossal artery (PHA). The PHA is a rare fetal variant of carotid-basilar anastomosis that elevates the risk of ischemia and embolic infarction within the posterior cerebral circulation in patients with carotid disease proximal to the anastomosis. Our case is highly unique because of the extremely rare nature of the PHA with associated ICA stenosis that extended to the PHA. Additionally, a novel treatment approach was employed by stenting and angioplasty while protecting both the anterior and posterior cerebral circulations.
