Background and Objective Cerebral vasospasm (CV) is a serious complication of subarachnoid hemorrhage (SAH) with high morbidity and mortality rates. The mechanism of CV has not been determined. There are many theories related to this unsolved issue, one of which supports CV as a two-stage phenomenon from a pathophysiologic perspective. The first stage consists of inhibition of neuronal nitric oxide synthase by oxyhemoglobin, which results in a decrease of nitric oxide (NO) production. The second stage consists of an increase in the levels of asymmetric dimethylarginine through bilirubin oxidation products (BOXes), which are oxidized by-products of hemoglobin metabolism...

Background and Objective Superficial temporal artery (STA)-middle cerebral artery (MCA) bypass is a procedure to reconstruct cerebral blood flow in the MCA territory. In some cases, the STA wall is thickened and the size discrepancy between STA and MCA is apparent. In such a situation, STA-MCA bypass is challenging. We present two patients who underwent STA-MCA bypass using STA in which a thickened intima was removed. We discuss the usefulness of this rescue technique. Patients and Results A patient with an atherosclerotic MCA occlusion and another with an occluded internal carotid artery are included...

Introduction Several different surgical techniques have been used in the treatment of patients with symptomatic Arnold-Chiari malformation type 1 (ACM-1) with or without syrinx. Endoscope-assisted decompression of the posterior fossa has been found to be safe and effective. We report our initial experience of endoscopic management of ACM-I. Material and Methods This was a prospective study of 15 symptomatic patients. Pre- and postoperative clinical status and computed tomography and magnetic resonance imaging findings were recorded...

Background and Study Aims Bronchogenic carcinoma is the cancer that most commonly metastasizes to the brain. The standard treatment schedule for these patients is still unclear, although recommendation level 1 class I advocates for surgical resection together with postoperative whole-brain radiotherapy for patients with good Karnofsky performance status (KPS). We performed a study to identify prognostic factors for the long-term survival of patients with brain metastases from non-small cell lung cancer (NSCLC)...

We report a case of a 66-year-old woman with a malignant transformation of a growth hormone (GH)-producing pituitary adenoma that was mainly located in the clivus. The patient originally presented with left oculomotor and abducens nerve palsies. Magnetic resonance imaging revealed a clival tumor separated from the normal pituitary gland, and the patient subsequently underwent transsphenoidal surgery. Analysis of the resected clival tissue revealed proliferation of tumor cells with slightly irregular nuclei but no mitosis...

The workshop of scientific medical faculties (Arbeitsgemeinschaft wissenschaftlicher medizinischer Fakultäten [AWMF]) of Germany has asked societies of specific medical disciplines to jointly publish guidelines on the treatment of diseases and injuries. On behalf of the Deutsche Gesellschaft für Neurochirurgie, its commission on guidelines initiated an interdisciplinary approach to publish guidelines on the treatment of head injury in adults. These guidelines were published in German by the AWMF in late 2015...

Kyung-Chul Choi, Jung Hyun Lee, Jin-Sung Kim, Dong Chan Lee, Choon Keun Park
Background and Study Aims The technique and instrumentation of percutaneous endoscopic lumbar diskectomy (PELD) have significantly improved. Thus its indications have been gradually expanding. Down-migrated disk, in particular, is regarded inaccessible by rigid instrumentation due to poor visualization and limited accessibility. We introduce a combination of transforaminal and interlaminar PELD for extensive down-migrated disk herniation at the L4-L5 level. Patients and Methods In the first case, a 48-year-old man had left L5 radicular pain...

Background and Objective To evaluate the impact of blood clearance mechanisms on neurologic damage and functional outcomes after intracerebral hemorrhage (ICH) in rats. Methods A rat model of ICH was established through pre-cannulation and injection of autologous arterial blood into the caudate nucleus. Blood was supplemented with 6-amino-caproic acid (a procoagulant), low-molecular-weight heparin (an anticoagulant), or vehicle. Relationships between hematoma volume and edema size and neurologic damage were assessed at different times...

The classical term "pituitary apoplexy" (PA) describes a clinical syndrome usually characterized by abrupt onset of headache accompanied by neurologic and/or endocrinologic deterioration due to sudden expansion of a mass within the sella turcica as a result of hemorrhage or infarction within a pituitary tumor and adjacent pituitary gland. PA is a medical emergency and a difficult diagnosis to establish. Thus this article reviews the presenting symptoms of PA patients to help clinicians recognize or at least suspect this critical condition early on...

Objective Infection following surgery is a serious complication, especially in neurosurgery. The aim of the study is to report the change of incidence rates of infection in patients undergoing elective neurosurgical procedures at a university hospital in South China as well as the risk factors. Material and Methods The medical records and postoperative courses for patients undergoing 1,033 neurosurgical procedures from 2008 to 2014 were reviewed retrospectively to determine the incidence of neurosurgical infection, the identity of the offending organisms, and the factors associated with infection...

Sushil Patkar
Cerebrospinal fluid (CSF) pathway studies have revealed that the CSF secreted from the choroid plexus of the ventricles after egressing from the fourth ventricle reaches the basal suprasellar cistern and ultimately the sylvian cisterns. From the sylvian cistern, the CSF travels over the cerebral convexity subarachnoid space to reach the superior sagittal sinus and enters the bloodstream. Diverting CSF from the lateral ventricle with a shunt catheter to the sylvian cistern can be an option to treat obstructive hydrocephalus...

Background Type I Chiari malformation presents without an associated hydromyelia in 30 to 70% of cases, yet there is no agreement regarding the optimal surgical treatment for these patients. We review our experience for treating symptomatic adult type I Chiari malformation without hydromyelia using a suboccipital bone decompression of the hindbrain and no duraplasty in 12 adult patients. Outcome was measured according to the Chicago Chiari Outcome Scale (CCOS). Results Nine of 12 patients were female; average age at surgery was 34...

Background Acute stroke causes intense and significant changes in the immune system as well as in the number and the ratio of various immune cells. Material and Methods Several large-scale studies have shown that ischemic stroke leaves the human body in a state of immunodepression. The regulatory T (Treg) cells may be strongly associated with a change of immune status. In this trial, we collected venous blood from a cohort of patients who were diagnosed with acute ischemic stroke within the last 24 hours (n = 139)...

Background Some patients under thalamic deep brain stimulation (DBS) for essential tremor (ET) experience habituation of tremor reduction. The nucleus ventralis intermedius (Vim) is the current main target side for ET in DBS. However, the dentatorubrothalamic tract (DRTT) is considered the relevant structure to stimulate. We investigated the distance between the active contact of the DBS electrode and the DRTT and compared this distance in patients with habituation of tremor reduction and good responders...
