[Migratory hyperdense posterior cerebral artery sign following intravenous thrombolysis].

Rev Neurol 2020 Jun;70(11):413-416

Hospital General Universitario de Valencia, 46014 Valencia, España.

Introduction: Computed tomography (CT) scanning of the brain continues to be the basic imaging mode in the acute phase of stroke. The hyperdense posterior cerebral artery sign is an early and infrequent radiological finding with topographic and prognostic value that must be taken into account in the initial CT scans.

Case Report: We report the case of a 79-year-old woman who suddenly presented with severe left homonymous hemianopsia, mild lower left facial paresis, 3/5 left hemiparesis and severe left hypaesthesia. Read More

Unusual enhancement patterns from inadvertent arterial contrast injection during CT angiography.

Radiology Department, Royal Melbourne Hospital, Parkville, Melbourne, Victoria, Australia; Faculty of Medicine, Dentistry, and Health Sciences at the University of Melbourne, Parkville, Melbourne, Victoria, Australia. Electronic address:

Investigation of cerebrovascular incidents typically involve non-contrast intracranial computed tomography (CT) and CT angiography (CTA) of the arch of aorta to vertex with or without CT perfusion. Though rare, inadvertent direct arterial contrast injection is a potentially serious complication which can alter contrast distribution and timing resulting in non-diagnostic intracranial studies. If unnoticed, they can be misinterpreted as pathology leading to further unnecessary investigations, increasing patient radiation dose and delaying appropriate management. Read More

Impact of cortical hemodynamic failure on both subsequent hemorrhagic stroke and effect of bypass surgery in hemorrhagic moyamoya disease: a supplementary analysis of the Japan Adult Moyamoya Trial.

J Neurosurg 2020 Mar 13:1-6. Epub 2020 Mar 13.

Objective: Here, the authors aimed to determine whether the presence of cerebral hemodynamic failure predicts subsequent bleeding attacks and how it correlates with the effect of direct bypass surgery in hemorrhagic moyamoya disease.

Methods: Data from the Japanese Adult Moyamoya (JAM) Trial were used in this study: 158 hemispheres in 79 patients. A newly formed expert panel evaluated the SPECT results submitted at trial enrollment and classified the cortical hemodynamic state of the middle cerebral artery territory of each hemisphere into one of the following three groups: SPECT stage (SS) 0 as normal, SS1 as decreased cerebrovascular reserve (CVR), and SS2 as decreased CVR with decreased baseline blood flow.

Removal of distal fragments of liquid embolic agents during arteriovenous malformation embolization using the TIGERTRIEVER 13: a technical report.

J Neurointerv Surg 2020 Feb 5. Epub 2020 Feb 5.

Neuroradiology, Alfried Krupp Krankenhaus Ruttenscheid, Essen, Germany.

Background: Arteriovenous malformations (AVMs) are vascular lesions that may be treated by an endovascular approach using liquid embolic agents but the control of the liquid embolic agent remains poor and a potential complication may be distal migration of embolic material. The TIGERTRIEVER 13 is a new stent retriever designed for stroke thrombectomy and has a version ideal for distal occlusions. We report our experience in the removal of embolic agent which had migrated into the distal vessels using the TIGERTRIEVER during PHIL/Onyx embolization of AVMs. Read More

Balloon anchoring technique for in hostile craniocervical arterial anatomy.

J Neurointerv Surg 2020 Feb 3. Epub 2020 Feb 3.

Neurology, Emory University School of Medicine, Atlanta, Georgia, USA

Background: Craniocervical catheter access in large vessel occlusion acute ischemic strokes can be challenging in cases of unfavorable aortic arch/cervical vascular anatomy, leading to lower recanalization rates, increased procedural time and worse clinical outcomes. We aim to demonstrate the feasibility of the balloon-anchoring technique (BAT) that can be attempted before switching to alternative access sites.

Methods: Retrospective review of prospectively collected information on 11 patients in which two variants of the BAT (proximal anchoring: balloon guide catheter (BGC) is inflated to provide support for distal access; distal anchoring: compliant balloon is inflated in an intracranial artery to allow advancement of the support system) were utilized to facilitate craniocervical access due to failure of conventional maneuvers.

A Multidisciplinary Approach in the Management of a Paediatric Posterior Fossa Ischaemic Stroke: A Case Report.

Cureus 2019 Dec 19;11(12):e6418. Epub 2019 Dec 19.

Neuroradiology Unit, Biomedical Sciences and Morphologic and Functional Images, University of Messina, Messina, ITA.

Posterior circulation acute ischaemic stroke in childhood is a rare but life-threatening disease. We describe a paediatric case of a 17-year-old Indian boy who was admitted to our centre for headache, nausea, vomiting, asthenia, and fever for two days. Computed tomography angiography (CTA), magnetic resonance angiography (MRA) and digital subtraction angiography (DSA) were performed, showing a thrombotic occlusion of the basilar artery due to focal dissection into the proximal third of the left vertebral artery.

Extracranial vertebral artery (VA) atherosclerosis is responsible for 14% to 32% of posterior circulation infarctions.1 In the posterior circulation, narrowing of the VA > 30% is significantly associated with strokes. Subclavian artery (SCA) atherosclerosis can produce subclavian steal. Read More

The Architect Who Lost the Ability to Imagine: The Cerebral Basis of Visual Imagery.

Brain Sci 2020 Jan 21;10(2). Epub 2020 Jan 21.

Department of Psychology, University of Copenhagen, 1726 Copenhagen, Denmark.

While the loss of mental imagery following brain lesions was first described more than a century ago, the key cerebral areas involved remain elusive. Here we report neuropsychological data from an architect (PL518) who lost his ability for visual imagery following a bilateral posterior cerebral artery (PCA) stroke. We compare his profile to three other patients with bilateral PCA stroke and another architect with a large PCA lesion confined to the right hemisphere. Read More

Two cases of symptomatic common carotid artery occlusion treated by carotid endarterectomy with L-shaped ministernotomy.

Surg Neurol Int 2020 3;11. Epub 2020 Jan 3.

Department of Neurosurgery, Tokyo Metropolitan Tama Medical Center, Fuchu, Tokyo, Japan.

Background: Common carotid artery occlusion (CCAO) is rare. Symptomatic lesions are resistant to medical treatment and revascularization are often required, but there is no consensus on the treatment of CCAO. In this paper, two cases of symptomatic CCAO treated by carotid endarterectomy (CEA) with L-shaped ministernotomy, in which the lesions extended to the beginning part of the CCA, are reported.

Detection of spreading depolarizations in a middle cerebral artery occlusion model in swine.

Acta Neurochir (Wien) 2020 Mar 15;162(3):581-592. Epub 2020 Jan 15.

Department of Neurosurgery, University Hospital Heidelberg, Im Neuenheimer Feld 400, 69120, Heidelberg, Germany.

Background: The main objective of this study was to generate a hemodynamically stable swine model to detect spreading depolarizations (SDs) using electrocorticography (ECoG) and intrinsic optical signal (IOS) imaging and laser speckle flowmetry (LSF) after a 30-h middle cerebral artery (MCA) occlusion (MCAo) in German Landrace Swine.

Methods: A total of 21 swine were used. The study comprised a training group (group 1, n = 7), a group that underwent bilateral craniectomy and MCAo (group 2, n = 10) and a group used for 2,3,5-triphenyltetrazolium (TTC) staining (group 3, n = 5). Read More
