Economic Comparison Between Endovascular Coiling vs Neurosurgical Clipping for Ruptured and Unruptured Intracranial Aneurysms in Austria.

Neurosurgery 2019 May;84(5):E272-E273

Introduction: Subarachnoid hemorrhage from a ruptured intracranial aneurysm poses a significant health hazard due to its high rates of mortality and disability. The 2 most commonly used treatment modalities of intracranial aneurysms are neurosurgical clipping and endovascular coiling. Through the decision on which treatment option should be chosen in every case is made based on medical indication, nevertheless, due to high socioeconomic burden of subarachnoid hemorrhage, it is also important to compare the healthcare expenditures, caused by clipping and coiling.

Meta-analysis of recent literature on utility of follow-up imaging in isolated perimesencephalic hemorrhage.

Clin Neurol Neurosurg 2019 Mar 11;180:111-116. Epub 2019 Mar 11.

Department of Radiology and Biomedical Imaging, Yale School of Medicine, Box 208042, Tompkins East 2, 333 Cedar St, New Haven, CT, 06520-8042, United States. Electronic address:

Objectives: Isolated perimesencephalic subarachnoid hemorrhage is an uncommon, distinct subtype of subarachnoid hemorrhage with a more benign prognosis. A negative computed tomographic angiogram has been shown to be reliable in excluding aneurysmal rupture as the underlying etiology. However, some studies continue advocating for more imaging to determine a vascular cause in perimesencephalic subarachnoid hemorrhage. Read More

Propentdyopents as Heme Degradation Intermediates Constrict Mouse Cerebral Arterioles and Are Present in the Cerebrospinal Fluid of Patients With Subarachnoid Hemorrhage.

Circ Res 2019 Apr 5. Epub 2019 Apr 5.

Hans Berger Department of Neurology, University Hospital Jena.

Rationale: Delayed ischemic neurological deficit is the most common cause of neurological impairment and unfavorable prognosis in subarachnoid hemorrhage (SAH) patients. Despite the existence of neuroimaging modalities that depict the onset of the accompanying cerebral vasospasm, preventive and therapeutic options are limited and fail to improve outcome owing to an insufficient pathomechanistic understanding of the delayed perfusion deficit. Previous studies have suggested that bilirubin oxidation products (BOXes), originating from released heme surrounding ruptured blood vessels, are involved in arterial vasoconstriction. Read More

Department of Emergency Medicine, Jackson Memorial Health System, Miami, FL 33136, USA.

Introduction: In the catastrophic neurologic emergency, a complete neurological exam is not always possible or feasible given the time-sensitive nature of the underlying disease process, or if emergent airway management is indicated. As the neurologic exam may be limited in some patients, the emergency physician is reliant on the assessment of brainstem structures to determine neurological function. Physicians thus routinely depend on advanced imaging modalities to further investigate for potential catastrophic diagnoses. Read More

Medical Officer, Department of Neurosurgery, College of Medical Sciences-Teaching Hospital, Bharatpur-10, Chitwan, Nepal.

Background: Aneurysmal subarachnoid hemorrhage may be associated with different cranial nerve palsies, with oculomotor nerve palsy (ONP) being the most common. ONP is especially associated with posterior communicating artery aneurysms, due to the anatomical proximity of the nerve to the aneurysmal wall. Anterior communicating artery (Acom) aneurysms are very unlikely to produce ONP due to the widely separated anatomical locations of Acom and oculomotor nerve. Read More

Perineural cyst with intracystic hemorrhage following aneurysmal subarachnoid hemorrhage: A case report.

Medicine (Baltimore) 2019 Feb;98(8):e14184

Department of Rehabilitation Medicine, Dongguk University Ilsan Hospital, Goyang, Korea and Dongguk University, Seoul, Korea.

Rationale: Most perineural cysts are asymptomatic and discovered incidentally at the time of imaging. Although enlargement of the perineural cyst (PC) through a ball-valve mechanism and resultant compression of the adjacent neural or bony structures are known to be a source of pain in PCs, the reason why asymptomatic PCs become symptomatic is unclear. The authors report a case of PC, which was presumed to become symptomatic after subarachnoid hemorrhage without enlargement of the pre-existing PC. Read More

Delayed development of a de novo contralateral middle cerebral artery aneurysm in a patient with hyperimmunoglobulin E syndrome: A case report.

Interv Neuroradiol 2019 Feb 25:1591019919828657. Epub 2019 Feb 25.

3 St Paul Radiology, St Paul, USA.

A 50-year-old female patient with hyperimmunoglobulin E syndrome (HIES) presented initially at the age of 48 years with subarachnoid hemorrhage (SAH) from a ruptured left middle cerebral artery (MCA) bifurcation aneurysm, which was treated successfully with coiling and microsurgical clipping. Angiography and cross-sectional imaging did not indicate evidence of any additional intracranial aneurysm. However, the patient presented two years later with SAH secondary to a new ruptured right MCA bifurcation aneurysm, which was treated successfully with microsurgical clipping. Read More

The endoscopic transpterional port approach: anatomy, technique, and initial clinical experience.

J Neurosurg 2019 Feb 22:1-11. Epub 2019 Feb 22.

1Division of Neurosurgery, Toronto Western Hospital, Krembil Brain Institute, University Health Network, and Department of Surgery, University of Toronto, Toronto, Ontario, Canada.

OBJECTIVEThe evolution of microsurgical and endoscopic techniques has allowed the development of less invasive transcranial approaches. The authors describe a purely endoscopic transpterional port craniotomy to access lesions involving the cavernous sinus and the anterolateral skull base.METHODSThrough single- or dual-port incisions and with direct endoscopic visualization, the authors performed an endoscopic transpterional port approach (ETPA) using a 4-mm straight endoscope in 8 sides of 4 formalin-fixed cadaveric heads injected with colored latex.

Practice Variation in the Diagnosis of Aneurysmal Subarachnoid Hemorrhage: A Survey of US and Canadian Emergency Medicine Physicians.

Neurocrit Care 2019 Feb 21. Epub 2019 Feb 21.

Department of Emergency Medicine, Stanford University Medical Center, Palo Alto, USA.

Background And Aims: Spontaneous subarachnoid hemorrhage (SAH) from a brain aneurysm, if untreated in the acute phase, leads to loss of functional independence in about 30% of patients and death in 27-44%. To evaluate for SAH, the American College of Emergency Physicians (ACEP) Clinical Policy recommends obtaining a non-contrast brain computed tomography (CT) scan followed by a lumbar puncture (LP) if the CT is negative. On the other hand, current evidence from prospectively collected data suggests that CT alone may be sufficient to rule out SAH in patients who present within 6 h of symptom onset while anecdotal evidence suggests that CT angiogram (CTA) may be used to detect aneurysms, which are the probable cause of SAH.

Non-traumatic Hematomyelia: A Rare Finding in Clinical Practice.

Eur J Case Rep Intern Med 2018 28;5(11):000961. Epub 2018 Nov 28.

Department of Internal Medicine, Centro Hospitalar do Meio Tejo, EPE, Tomar, Portugal.

Non-traumatic haematomyelia is a rare finding of acute onset, which in most cases is the result of arteriovenous malformations (AVM), tumours, coagulation disorders or autoimmune conditions, but may also be secondary to treatment with anticoagulants and radiotherapy. We present the case of a 58-year-old woman with sudden onset cervical pain, followed by asymmetric diminution of strength in the upper limbs with reduced pain sensitivity. The diagnosis of AVM at the C7 and D1 levels was made following cervico-dorsal magnetic resonance imaging and angiography. Read More

Thromboxane-prostaglandin receptor antagonist, terutroban, prevents neurovascular events after subarachnoid haemorrhage: a nanoSPECT study in rats.

Crit Care 2019 Feb 11;23(1):42. Epub 2019 Feb 11.

Department of Anaesthesiology and Critical Care Medicine, INT (Institut de Neurosciences de la Timone), University Hospital Timone, Aix Marseille University, Marseille, France.

Background: Several lipid metabolites in cerebrospinal fluid are correlated with poor outcomes in aneurysmal subarachnoid haemorrhage. Most of these metabolites bind to ubiquitous thromboxane-prostaglandin (TP) receptors, causing vasoconstriction and inflammation. Here, we evaluated terutroban (TBN), a specific TP receptor antagonist, for the prevention of post-haemorrhage blood-brain barrier disruption, neuronal apoptosis and delayed cerebral hypoperfusion.

Altered beta-band functional connectivity may be related to 'performance slowing' in good outcome aneurysmal subarachnoid patients.

Neurosci Lett 2019 Apr 31;699:64-70. Epub 2019 Jan 31.

Neurosciences and Mental Health, SickKids Research Institute, Toronto, Canada; Division of Neurology, The Hospital for Sick Children, University of Toronto, Canada. Electronic address:

Recent evidence suggests that good neurological outcome in subarachnoid hemorrhage (SAH) does not equate to good neuropsychological and cognitive outcome. These individuals continue to face cognitive difficulties in tasks involving mental flexibility, short-term memory and attention, resulting in decreased independence in daily living and reduced ability to return to work. In the current study, we examined the functional connectivity profiles using magnetoencephalography (MEG) in SAH patients, versus controls, during a visual short-term memory, 1-back, task. Read More
