    Institute of Neurosurgery, Catholic University of Rome, L.go A. Gemelli, 8, 00168, Rome, Italy.
    Background: Vertebral artery (VA) identification within the suboccipital triangle is a key step in craniocervical junction surgery. Often VA exposition at this level is arduous (space-occupying lesions, previous surgery); to identify VA more proximally may prove useful in complex cases. An alternative triangle is present just below the suboccipital one, where VA can be easily controlled; we named it the inferior suboccipital triangle (IST). Read More

    Finger tapping and verbal fluency post-tap test improvement in INPH: its value in differential diagnosis and shunt-treatment outcomes prognosis.
    Acta Neurochir (Wien) 2017 Aug 21. Epub 2017 Aug 21.
    Department of Neurosurgery, University of Athens, Evangelismos Hospital, EKNE Ploutarchou 3 str. Kolonaki, TK. 10675, Athens, Greece.
    Background: Idiopathic normal pressure hydrocephalus (INPH) diagnosis is challenging as it can be mimicked by other neurological conditions, such as neurodegenerative dementia and motor syndromes. Additionally, outcomes after lumbar puncture (LP) tap test and shunt treatment may vary due to the lack of a common protocol in INPH assessment. The present study aimed to assess whether a post-LP test amelioration of frontal cognitive dysfunctions, characterizing this syndrome, can differentiate INPH from similar neurological conditions and whether this improvement can predict INPH post-shunt outcomes.

    Technique for rerouting a bridging vein that hinders the anterior interhemispheric approach: a technical note.
    Acta Neurochir (Wien) 2017 Aug 1. Epub 2017 Aug 1.
    Department of Neurosurgery, Fuji Brain Institute and Hospital, 270-12 Sugita, Fujinomiya City, Shizuoka, 418-0021, Japan.
    Background: The frontal bridging vein, which is the venous drainage route of the frontal cortex into the superior sagittal sinus (SSS), sometimes poses an obstacle in the anterior interhemispheric approach during surgery for anterior cerebral artery aneurysms. Although severe complications including venous infarction or edema due to damage to the bridging vein are well known, only a few reports have discussed how to avoid venous injury when we must sacrifice the bridging vein to obtain an appropriate surgical field. This report describes a microvascular technique performed in two patients who underwent rerouting of the bridging vein to obtain an appropriate anterior interhemispheric surgical corridor to treat a ruptured anterior cerebral artery aneurysm.
