Craniovascular traits and braincase morphology in craniosynostotic human skulls.

J Anat 2021 Jul 8. Epub 2021 Jul 8.

Programa de Paleobiología, Centro Nacional de Investigación sobre la Evolución Humana, Burgos, Spain.

Middle meningeal vessels, dural venous sinuses, and emissary veins leave imprints and canals in the endocranium, and thus provide evidence of vascular patterns in osteological samples. This paper investigates whether craniovascular morphology undergoes changes in craniosynostotic human skulls, and if specific alterations may reflect structural and functional relationships in the cranium. The analyzed osteological sample consists of adult individuals with craniosynostoses generally associated with dolichocephalic or brachycephalic proportions, and a control sample of anatomically normal adult skulls.

Chronic colitis exacerbates NLRP3-dependent neuroinflammation and cognitive impairment in middle-aged brain.

J Neuroinflammation 2021 Jul 6;18(1):153. Epub 2021 Jul 6.

Department of Rehabilitation Medicine, The Third Affiliated Hospital, Sun Yat-sen University, 600 Tianhe Road, Guangzhou, 510630, Guangdong, China.

Background: Neuroinflammation is a major driver of age-related brain degeneration and concomitant functional impairment. In patients with Alzheimer's disease, the most common form of age-related dementia, factors that enhance neuroinflammation may exacerbate disease progression, in part by impairing the glymphatic system responsible for clearance of pathogenic beta-amyloid. Inflammatory bowel diseases (IBDs) induce neuroinflammation and exacerbate cognitive impairment in the elderly. Read More

Pediatric middle meningeal artery embolization for chronic subdural hematoma: A case report.

Surg Neurol Int 2021 25;12:239. Epub 2021 May 25.

Department of Neurosurgery, Medical College of Wisconsin, Milwaukee, Wisconsin, United States.

Background: The most common neuroradiological finding in pediatric nonaccidental trauma (NAT) is subdural hematoma (SDH). Management options for pediatric SDH range from conservative clinical surveillance to craniotomy or decompressive craniectomy. The middle meningeal artery (MMA) indirectly feeds the hematoma; thus, MMA embolization is an alternative or adjunct to current surgical treatments in adults. Read More

Efficacy and mid-term outcome of middle meningeal artery embolization with or without burr hole evacuation for chronic subdural hematoma compared with burr hole evacuation alone.

J Neurointerv Surg 2021 Jun 29. Epub 2021 Jun 29.

Department of Diagnostic and Interventionell Radiology and Neuroradiology, University Hospital Augsburg, Augsburg, Bavaria, Germany.

Background: Chronic subdural hematoma (CSDH) is a common neurosurgical condition with high recurrence rates. Repeated microbleedings from fragile neo-vessels supplied by peripheral branches of the middle meningeal artery (MMA) are believed to be responsible for the growth and recurrence of CSDH. Thus, MMA embolization might be a promising method to prevent re-bleedings and recurrences. Read More

Spontaneous chronic subdural hematoma due to cerebral cortical artery rupture: First case report and review of pertinent literature.

Neuroradiol J 2021 Jun 21:19714009211026891. Epub 2021 Jun 21.

Kaiser Permanente, USA.

Introduction: Chronic subdural hematoma (CSDH) is generally attributed to pathological changes in the dural arterial system, which has led to growing utilization of middle meningeal artery (MMA) embolization in CSDH treatment. There are no case reports of CSDH due to cerebral cortical artery perforation.

Method: We report a case of spontaneous CSDH caused by cortical artery rupture that was identified on digital subtraction angiography and could be visualized on computed tomographic angiography (CTA). Read More

J Neurointerv Surg 2021 Jun 17. Epub 2021 Jun 17.

Neurosurgery, University at Buffalo School of Medicine and Biomedical Sciences, Buffalo, New York, USA

N-butyl 2-cyanoacrylate (nBCA) is a fast-acting liquid adhesive that polymerizes when it comes in contact with blood anions. We present the principles of nBCA preparation and delivery for tumor embolization of a right convexity meningioma in a patient who presented with a 6-month history of word-finding difficulty and memory loss video 1 Angiography of the middle meningeal artery showed a hairpin turn that was not negotiable with a number of different microwires, including the Synchro-2, Chikai 014 and Balt hybrid 008 wire. Due to the tortuous hairpin turn, the microcatheter position was distal to the tumor blush for the convexity meningioma. Read More

Piezosurgery for safe and efficient petrous bone cutting in cerebellopontine angle and petroclival meningioma surgery.

J Clin Neurosci 2021 Jul 21;89:319-328. Epub 2021 May 21.

Department of Neurosurgery, Medical Center - University of Freiburg, Faculty of Medicine, University of Freiburg, Germany.

Intradural petrous bone drilling has become a widespread practice, providing extended exposure in the removal of cerebellopontine angle (CPA) or petroclival tumors. Adjacent neurovascular structures are at risk, however, when drilling is performed in this deep and narrow area. Hence, this study evaluates the use of Piezosurgery (PS) as a non-rotating tool for selective bone cutting in CPA surgery. Read More

The "Shiny and Thick High Heel Sign" : A novel radiologic sign for detecting intracranial dural arteriovenous fistulas with time-of-flight magnetic resonance angiography.

Clin Neuroradiol 2021 Jun 8. Epub 2021 Jun 8.

Department of Neuroradiology, University Medical Center Schleswig-Holstein, Lübeck University, Lübeck, Germany.

Purpose: Together with the foramen ovale, the middle meningeal artery (MMA) looks like a high heel shoe print on axial time-of-flight magnetic resonance angiography (TOF-MRA) images, with the MMA resembling the heel. Cranial dural arteriovenous fistulas (DAVF) are often fed by the MMA, which can lead to an increase of signal intensity and diameter of this vessel, resulting in a more "shiny" and "thick" high heel print appearance than on the contralateral side. We describe this finding as a novel radiologic sign and provide cut-off values for the ratios of MMA signal intensities and diameters for predicting the presence of a DAVF. Read More
