    The role of computed tomography in the screening of patients presenting with symptoms of an intracranial tumour.
    Acta Neurochir (Wien) 2018 Feb 5. Epub 2018 Feb 5.
    Department of Neurosurgery, Aarhus University Hospital, Aarhus, Denmark.
    Background: To improve the quality of care for brain cancer patients, the Danish Ministry of Health has set standards for the diagnosis and treatment. When a patient is suspected of having a malignant tumour involving the brain, it is required that a magnetic resonance imaging of the cerebrum (MRI-C) be obtained within seven calendar days of referral from a primary care provider. This standard has the potential to consume MR imaging time that might otherwise be used for evaluation or treatment monitoring of other patients. Read More

    Objective: Intracranial aneurysms are extremely rare in infants, especially less than 1 year old. This study aimed to analyze the frequency of infantile intracranial aneurysm in our department and investigate the clinical characteristics, treatment strategies, and outcomes of this disease.

    Methods: Six infants under 1 year old in 4350 patients with intracranial aneurysms were retrospectively analyzed from January 2010 to December 2016. Read More

    Fluorescein videoangiography during extracranial-to-intracranial bypass surgery: preliminary results.
    Acta Neurochir (Wien) 2018 Jan 6. Epub 2018 Jan 6.
    Department of Neurosurgery, Charitè-Universitätsmedizin Berlin, Augustenburger Platz 1, 13353, Berlin, Germany.
    Background: Over the last years, intraoperative use of fluorescein is gaining ground in the field of neurosurgery, due to development of a microscope-integrated YELLOW 560 module, with reported experiences in brain malignancies, aneurysms, and arteriovenous malformation surgery. The aim of this study is to determine the feasibility and value of fluorescein videoangiography during bypass procedures.

    Methods: The authors enrolled 11 patients who underwent extracranial-to-intracranial bypass for moyamoya disease, atherosclerotic steno-occlusive cerebrovascular disease, and flow replacement during a giant middle cerebral artery (MCA) aneurysm treatment. Read More

    Cerebellar infarction after posterior direct reduction and fixation to treat an unstable Jefferson fracture: a case report.

    Department of Neurosurgery, Sanggye Paik Hospital, Inje University College of Medicine, Dongil-ro 1342, Nowon-gu, Seoul, 01757, South Korea.
    A 42-year-old man had an unstable Jefferson type IV atlas fracture with unilateral vertebral artery occlusion after a diving accident. We performed C1-ring reconstruction with a crosslink rod and C2 fixation to directly reduce the fracture fissure. Within 6 h, cerebellar hemisphere infarction developed. Read More

    Gross total resection of pituitary adenomas after endoscopic vs. microscopic transsphenoidal surgery: a meta-analysis.

    Cushing Neurosurgical Outcomes Center, Department of Neurosurgery, Brigham and Women's Hospital, Harvard Medical School, Boston, MA, 02115, USA.
    Background: Microscopic transsphenoidal surgery (mTSS) is a well-established method to address adenomas of the pituitary gland. Endoscopic transsphenoidal surgery (eTSS) has become a viable alternative, however. Advocates suggest that the greater illumination, panoramic visualization, and angled endoscopic views afforded by eTSS may allow for higher rates of gross total tumor resection (GTR). Read More
