Two illustrative cases of traumatic intracranial cerebral artery dissection in children.

Traumatic intracranial cerebral artery dissection (ICAD) in the pediatric population is relatively rare. We report two traumatic ICAD cases in children. Case 1: A 13-year-old boy presented with headache and left hemiparesis after body contact while playing basketball.

Treatment of aneurysmal subarachnoid hemorrhage in subacute phase; retrospective comparison of treatment in sub- and hyper-acute phases.

Objective: As soon as possible treatment initiation for aneurysmal subarachnoid hemorrhage (aSAH) is recommended. However, some patients require treatment in "subacute" phase of aSAH, defined in this study as "more than one day after the onset". To establish an optimal treatment strategy for these patients, we retrospectively analyzed the clinical experience of treating ruptured aneurysm with either clipping or coiling in subacute phase.

Successful treatment with urgent revascularization and parent artery occlusion for a ruptured intratumoral aneurysm following prior meningioma surgery: illustrative case.

Background: An intratumoral aneurysm encased within the associated intracranial tumor is rare, and hemorrhage caused by its rupture is even more rare. While urgent and adequate surgical treatment is important, the treatment can be difficult given the limited understanding of this rare condition.

Observations: A 69-year-old man who had undergone meningioma surgery 30 years prior presented with a disturbance in consciousness.

Clinical characteristics of endovascular treatment for acute ischemic stroke with atherosclerotic etiology: Factors associating its clinical outcome.

Objective: Clinical characteristics of endovascular treatment (EVT) for acute ischemic stroke (AIS) secondary to atherosclerosis are not fully delineated. An optimal treatment strategy with considerations of stroke etiology has not yet been established. Here-in, we performed retrospective analysis of EVT for atherosclerotic AIS.

Characteristics of MRI Findings after Subarachnoid Hemorrhage and D-Dimer as a Predictive Value for Early Brain Injury.

Background: The pathological mechanisms of early brain injury (EBI) have remained obscure. Several studies have reported on the neuroradiological findings of EBI. However, to our knowledge, no study has attempted to explore the mechanism of EBI after subarachnoid hemorrhage (SAH).

Acute systematic inflammatory response syndrome and serum biomarkers predict outcomes after subarachnoid hemorrhage.

Subarachnoid hemorrhage (SAH) can trigger immune activation sufficient to induce systematic inflammatory response syndrome (SIRS). Serum inflammatory biomarkers and SIRS can predict a poor outcome. The relationship between surgical stress and inflammatory response is well known but described in few reports in the neurosurgical population.

[Dural Arteriovenous Fistulae in the Tentorium Manifesting as Dementia].

Background: Tentorial dural arteriovenous fistula(dAVF)is a relatively rare disease which accounts for about 4.8% of all types of dAVF reported in Japan. Approximately 12.

Superficial Temporal Artery-Superior Cerebellar Artery Bypass with Anterior Petrosectomy.

Background: Superficial temporal artery (STA) to superior cerebellar artery (SCA) bypass is associated with a relatively high risk of surgical complications, such as hematoma and/or edema caused by temporal lobe retraction. Therefore, the right side is typically used to avoid retraction of the left temporal lobe. In this report, we present a case of left STA-SCA bypass with anterior petrosectomy to avoid retraction of dominant-side temporal lobe and describe the surgical technique in detail.

Impact of Antiplatelets and Anticoagulants on the Prognosis of Intracerebral Hemorrhage.

Background: Intracerebral hemorrhage (ICH) associated with antithrombotic therapy (AT) is becoming more common as the use of those medications increases in the aging population.

Methods: This study included 490 consecutive patients hospitalized for nontraumatic ICH in a single center during an 8-year period, which was subdivided into former (2008-2011) and latter (2012-2015). Patients were classified into those with no antithrombotic drugs (NATs) and those with AT.

Treatment of Recurrent Intracranial Aneurysms After Clipping: A Report of 23 Cases and a Review of the Literature.

Objective: There are no established treatment strategies for aneurysms that recur after clipping. In this study, we present cases of patients who experienced recurrent aneurysms after clipping and subsequently underwent surgical intervention.

Methods: Between 2004 and 2015, we surgically treated 23 aneurysms that recurred at a previously clipped site.

Idiopathic fourth ventricle outlet obstruction successfully treated by endoscopic third ventriculostomy: a case report.

Introduction: Fourth ventricle outlet obstruction (FVOO) is a rare cause of obstructive hydrocephalus. We describe a case of idiopathic FVOO that was successfully treated with endoscopic third ventriculostomy (ETV).

Case Report: A 3-year old boy without any remarkable medical history presented with a headache and vomiting.

[Metronidazole-Induced Encephalopathy during Brain Abscess Treatment:Two Case Reports].

Metronidazole is a widely used antibiotic against anaerobic bacteria and protozoa. We report two cases of metronidazole-induced encephalopathy(MIE)during treatment of a brain abscess with metronidazole. The patients developed mental disturbance, and brain MRI showed reversible signals on DWI, FLAIR, and T2.

Case Report: Trigeminal Neuralgia Caused by a Minute Meningioma with Hyperostosed Suprameatal Tubercle.

Cerebellopontine angle tumors might occasionally provoke trigeminal neuralgia but are usually large enough to be diagnosed radiographically. We present a case of trigeminal neuralgia caused by a very small meningioma covering the suprameatal tubercle that displayed hyperostosis at the entrance of Meckel's cave and was not obvious on routine magnetic resonance (MR) images. A 72-year-old woman with intractable trigeminal neuralgia in the left V3 territory was referred to our institution.

[Rapid spontaneous resolution of acute epidural hematoma in an infant:a case report].

Resolution of acute epidural hematoma (AEDH) usually takes several weeks. The authors present an infantile case of AEDH that rapidly decreased within a day and review the literature. A 7-month-old boy fell from a height of approximately one meter and sustained a head injury.

[Reversible cerebral vasoconstriction syndrome associated with stroke: three case reports].

Reversible cerebral vasoconstriction syndrome(RCVS)is characterized by severe headache and diffuse segmental constriction of cerebral arteries that resolves spontaneously within a few months. Although manifestations of stroke are not included in diagnostic criteria of RCVS, it is known that some cases may be associated with stroke, including intracerebral hemorrhage, subarachnoid hemorrhage, or cerebral infarction. We present three cases of RCVS associated with various types of stroke, and then review the literature.

Basilar trunk aneurysm surgically treated with anterior petrosectomy and external carotid artery-to-posterior cerebral artery bypass: technical note.

Objective: We discuss a detailed surgical technique, its indications, and potential pitfalls in its use.

Methods: A surgical procedure combining Kawase's anterior petrosectomy and external carotid artery-to-posterior cerebral artery high-flow bypass was performed for the treatment of a patient with a fusiform basilar trunk aneurysm.

Results: Follow-up angiography revealed the successful obliteration of the aneurysm and that the graft was functioning well.
