Atorvastatin combined with dexamethasone in chronic subdural haematoma (ATOCH II): study protocol for a randomized controlled trial.

Background: Chronic subdural haematoma (CSDH) is a common condition in the elderly that often requires neurosurgical management. For small CSDH, evidence has emerged that statins may reduce haematoma volume and improve outcomes, presumably by reducing local inflammation and promoting vascular repair. We wish to extend this evidence in a study that aims to determine the efficacy and safety of atorvastatin combined with low-dose dexamethasone in patients with CSDH.

Using a New Landmark of the Most External Point in the Embolization of Distal Anterior Choroidal Aneurysms: A Report of Two Cases.

There are landmarks on the course of the anterior choroidal artery (AChoA), such as the original point (OP) and the plexal point (PP), as documented in previous articles. In these previous articles, the AChoA was the terminal branch of the internal carotid artery (ICA), which had two segments throughout its course. The first cisternal segment began from the origin and ended at the point where the artery reached the choroidal fissure (the PP).

Use of a compact high-definition two-dimensional exoscope in surgical treatment of large vestibular schwannoma.

Background: Extra-corporeal video telescope operating monitor system provides a necessary instrument to perform high-precision neurosurgical procedures that could substitute or supplement the traditional surgical microscope. The present study was designed to evaluate a compact high-definition two-dimensional exoscope system for assisting in surgical removal of large vestibular schwannoma (VS), as an alternative to a binocular surgical microscope.

Methods: Patients with Koos grade 3 and grade 4 VS undergoing surgery were enrolled in this prospective cohort study between January 2013 and June 2018.

Risk factors for corticosteroid insufficiency during the sub-acute phase of acute traumatic brain injury.

Hypothalamic-pituitary-adrenal axis dysfunction may lead to the occurrence of critical illness-related corticosteroid insufficiency. Critical illness-related corticosteroid insufficiency can easily occur after traumatic brain injury, but few studies have examined this occurrence. A multicenter, prospective, cohort study was performed to evaluate the function of the hypothalamic-pituitary-adrenal axis and the incidence of critical illness-related corticosteroid insufficiency during the sub-acute phase of traumatic brain injury.

Electrical stimulation improved cognitive deficits associated with traumatic brain injury in rats.

Introduction: Cognitive deficits associated with traumatic brain injury (TBI) reduce patient quality of life. However, to date, there have been no effective treatments for TBI-associated cognitive deficits. In this study, we aimed to determine whether electrical stimulation (ES) improves cognitive deficits in TBI rats.

Cold water swimming pretreatment reduces cognitive deficits in a rat model of traumatic brain injury.

A moderate stress such as cold water swimming can raise the tolerance of the body to potentially injurious events. However, little is known about the mechanism of beneficial effects induced by moderate stress. In this study, we used a classic rat model of traumatic brain injury to test the hypothesis that cold water swimming preconditioning improved the recovery of cognitive functions and explored the mechanisms.

Effect of ATorvastatin On Chronic subdural Hematoma (ATOCH): a study protocol for a randomized controlled trial.

Background: Chronic subdural hematoma (CSDH) is a common disease that is more prevalent in older people. Surgical intervention is a safe treatment of choice. However, the recurrence rate is relatively high and the outcome is not always satisfactory among surgically treated patients.

[Intraoperative magnetic resonance imaging-guided functional neuronavigation plus intraoperative neurophysiological monitoring for microsurgical resection of lesions involving hand motor area].

Objective: To explore the methods and applications of intraoperative magnetic resonance imaging (iMRI)-guided functional neuronavigation plus intraoperative neurophysiological monitoring (IONM) for microsurgical resection of lesions involving hand motor area.

Methods: A total of 16 patients with brain lesions adjacent to hand motor area were recruited from January 2011 to April 2012. All of them underwent neuronavigator-assisted microsurgery.

[Application of high-field intraoperative magnetic resonance imaging in stereotactic aspiration and drainage of hypertensive hematomas].

Objective: To explore the application values of high-field intraoperative magnetic resonance imaging (MRI) in stereotactic aspiration and drainage of hypertensive hematomas.

Methods: During a period of August 2011 to January 2012, 11 patients with hypertensive hemorrhage were examined preoperatively by conventional MRI and diffusion tensor imaging (DTI) with 1.5T intraoperative MRI system (Signa HDi, GE, USA) at Tianjin Medical University General Hospital.

Primary granulomatous hypophysitis: a case report and literature review.

Primary granulomatous hypophysitis (PGH) is a rarely occurred inflammatory disease of unknown etiology. We retrospective review a case of PGH treated by microsurgical transsphenoidal approach and review the appropriately documented cases of PGH collected from the literatures. The patient was a 56-year-old female who presented with 4 months history of headache and 2 months history of polyuria and polydipsia.

[Stereotactic resection of small intracerebral lesions in motor cortex using blood oxygen level depended functional magnetic resonance imaging and diffusion tensor imaging fusion guidance].

Objective: To explore the effect of stereotactic resection of small intracerebral lesions located in the motor cortex using blood oxygen level depended functional magnetic resonance imaging (BOLD-fMRI) and diffusion tensor imaging (DTI) fusion guidance.

Methods: Fifteen patients with lesions in posterior frontal lobe to anterior central gyrus, 1.5-3 cm in diameter, underwent combined three-dimensional (3D) enhancement MRI with BOLD-fMRI, and DTI.
