Transradial Mechanical Thrombectomy Using a Radial-specific Neurointerventional Guiding Sheath for Anterior Circulation Large-Vessel Occlusions: Preliminary Experience and Literature Review.

Background: Transradial mechanical thrombectomy (MT) is increasingly used because it is associated with a low incidence of vascular access site complications. However, transradial carotid cannulation can be technically challenging to perform in patients with an unfavorable supra-aortic takeoff. In this study, the feasibility and safety of a new transradial MT system with a radial-specific neurointerventional guiding sheath-6F Simmons guiding sheath was evaluated-in patients with anterior circulation large-vessel occlusions.

Delayed Detection of Hydrocephalus following Mildly Traumatic Subarachnoid Hemorrhage in Corticobasal Degeneration: A Case Report.

A 65-year-old woman presented with slowly progressive aphasia with gait disturbance associated with parkinsonism. She experienced a fall that resulted in a brain trauma. Brain imaging revealed a small amount of subarachnoid hemorrhage (SAH) with intraventricular bleeding.

Pseudohypoxic brain swelling and secondary hydrocephalus with pseudomeningocele after lumbar surgery: a case report.

Background: Postoperative intracranial complications are rare in spine surgery not including cranial procedures. We describe an uncommon case of pseudohypoxic brain swelling (PHBS) and secondary hydrocephalus after transforaminal lumbar interbody fusion (TLIF) presenting as impaired consciousness and repeated seizures.

Case Presentation: A 65-year-old man underwent L4-5 TLIF for lumbar spondylolisthesis and began experiencing generalized seizures immediately postoperatively.

Very small vestibular schwannoma as the source of fatal subarachnoid hemorrhage: a case report.

Background: Subarachnoid hemorrhage (SAH) is commonly caused by an aneurysm, trauma, other vascular diseases, and infrequently by a metastatic tumor or glioma. SAH due to a benign intracranial tumor, such as a vestibular schwannoma (VS), is rare. We report a case in which a very small (1 mm) VS caused fatal SAH.

Inter-capsular resection of cervical vagus nerve schwannoma.

Cervical vagus nerve schwannoma is rare and its surgical procedure is controversial. The tumor is in general benign and slowly growing without causing symptoms, and therefore it should be advised to remove the tumor while preserving neural function. We operated on two patients with cervical vagus nerve schwannoma with the inter-capsular resection technique proposed by Hashimoto et al.

Acetyl-l-carnitine enhances myelination of regenerated fibers of the lateral olfactory tract.

It is well known that acetyl-l-carnitine (ALC) has various neuroprotective effects against neurodegenerative diseases. In addition, it has been reported that ALC facilitates myelination of regenerated axons after peripheral nerve injuries. We previously reported that spontaneous regeneration of the lateral olfactory tract (LOT), the main fiber tract of the central olfactory system, consistently occurred in newborn rats and a majority of these regenerated fibers were unmyelinated in neonatally LOT-transected young adult rats.

Morphological analysis of regenerated bulbar fibers in relation to neonatal olfaction.

It was revealed that regeneration of the lateral olfactory tract (LOT) occurred in developing rats and the regenerated olfactory system was functional 4 weeks after transection. The aim of this study was to determine the earliest onset of functional recovery in LOT-injured rats and to quantify regenerated nerve components with functional correlation. Neonatal rats on postnatal day (P) 2 were subjected to unilateral transection of the left LOT and underwent unilateral removal of the right olfactory bulb on P11.

Two specific tongue regions receive bilateral hypoglossal innervation: a study in neonatal rat pups.

Objective: The purpose of this study was to investigate the functional role of bilateral hypoglossal (XII) nerve innervation of the tongue.

Materials And Methods: The possibility of bilateral innervation of XII nerve in the tongue was examined using postmortem fibre tracing in normal neonatal rats. In addition, immunohistochemical testing for synaptophysin or vesicular acetylcholine transporter (VAChT) was carried out in unilaterally XII nerve-resected neonatal rats.

Subtemporal transtentorial approach for recurrent trigeminal neuralgia after microvascular decompression via the lateral suboccipital approach: case report.

Microvascular decompression (MVD) via lateral suboccipital craniotomy is the standard surgical intervention for trigeminal neuralgia (TN). For recurrent TN, difficulties are sometimes encountered when performing reoperation via the same approach because of adhesions and prosthetic materials used in the previous surgery. In the present case report the authors describe the efficacy of the subtemporal transtentorial approach for use in recurrent TN after MVD via the lateral suboccipital approach.

A case of presumably Rathke's cleft cyst associated with postoperative cerebrospinal fluid leakage through persisting embryonal infundibular recess.

Persisting embryonal infundibular recess (PEIR) is a rare anomaly of the third ventricular floor. Only eight cases have been published. In this report, a case of presumably Rathke's cleft cyst associated with cerebrospinal fluid leakage caused by PEIR is described.

Surgical strategy and results of treatment for dumbbell-shaped spinal neurinoma with a posterior approach.

Objective: Total removal of neurinomas is generally an achievable goal that yields good results; however, dumbbell-shaped neurinomas often present challenges for complete resection. Some extensive surgical approaches for complete removal have been reported to lead to severe complications. Therefore, the surgical strategy for dumbbell-shaped neurinomas is controversial.

Pontine infarction caused by medial branch injury of the basilar artery as a rare complication of cisternal drain placement.

We present a rare complication of cisternal drain placement during aneurysm surgery. A ruptured anterior communicating artery aneurysm was clipped through a right pterional approach. A cisternal drain was inserted from the retro-carotid to the prepontine cistern.

Hydrocephalus associated with cystic dilation of the foramina of Magendie and Luschka.

Cystic malformations in the posterior cranial fossa result from developmental failure in the paleocerebellum and meninges. The authors present the case of an infant with hydrocephalus associated with cystic dilation of the foramina of Magendie and Luschka. This 7-month-old female infant presented with sudden onset of tonic-clonic seizures.
