Vestibular schwannoma
Abstract
The state of the art of vestibular schwannoma management is reviewed with discussion of pertinent literature to bring out the current results and controversies in this field. Microsurgery results from four major series are discussed along with data from those using gamma knife or linear accelerators to treat these tumors. (Source: Critical Reviews in Neurosurgery)

Radiosurgery for metastatic brain tumors
Abstract
Since the life span of patients with metastatic brain tumors is quite limited, the aim of the treatment is to prolong their useful quality of life with minimally invasive therapeutic modalities. Although gamma knife radiosurgery (GKR) is widely used and accepted as a standard therapeutic modality for treating metastatic brain tumors today, there are still several problems to be clarified. The indication of GKR for metastatic brain tumors is based on the size, number of metastases, the state of primary cancer, systemic metastases, general condition of the patient, the radiosensitivity of primary...

Diffuse axonal injury: its role in diffuse brain injury and its significance for severe disability and vegetative state
Abstract
Diffuse traumatic brain injury and combinations of diffuse with focal impact traumatic brain injury can cause widespread diffuse axonal injury (DAI) to the white matter. DAI is often the main reason for a persistent vegetative state or a persistent dementia after acute brain damage and may be responsible for a poor outcome after neurosurgical interventions. In the last few years, amyloid precursor protein (APP) has attracted interest as an early marker of DAI staining only injured axons, whereas background uninjured axons are not stained, in contrast to the more traditional demonstration of DAI...

Interventional neuroradiology
Abstract
In this review, papers have been selected with the object of informing the reader about research developed by interventional neuroradiologists to improve the quality of materials, to further knowledge of their performance and use, to search for new items, and to follow-up and check therapeutic results. Animal models, in-vitro models, and special applications of technical possibilities are described and discussed with interesting and promising results. (Source: Critical Reviews in Neurosurgery)

Concussion confusion
Abstract
The literature on concussion contains elements of confusion in that the word is used for cases in which there is obviously permanent neuronal damage. In turn, this leads to confusion regarding the prognosis and immediate management of cases where a blow to the head is the primary injury. If we adhere to the classic definition of concussion, “a transient disturbance of neurologic function with no structural damage”, a lot of this confusion will disappear, including that surrounding prolonged post-concussion syndrome (PPCS), second impact syndrome (SIS), and predisposition to become concussed...

Cervical spinal trauma
Abstract
Over the past years, significant advances have taken place in basic research, imaging, and in the treatment of cervical spine injuries. The pathophysiological understanding of spinal cord injury has been considerably improved by basic research. Spinal cord damage occurs as a result of primary mechanical insult of secondary ischemic and biochemical tissular alterations. Twenty percent of patients with a major spine injury will have a second spine injury at another level. Such lesions include arterial dissections. These patients often suffer simultaneous but unrelated chest or abdominal injuries....

Deep brain stimulation for Parkinson ’s disease: how to select candidates for pallidal or subthalamic stimulation
This article presents a review of recent reports that describe follow-up results and double-blind studies on the signs for r elief of each type of parkinsonian symptom, following GPi or STN stimulation. It also includes a discussion of how further research should be organized in order to identify whether GPi or STN stimulation exerts the greatest effect on particular kinds of parkinsonian symptoms. < /p > (Source: Critical Reviews in Neurosurgery)

Anterior cervical discectomy for one- and two-level cervical disc disease: the controversy surrounding the question of whether to fuse, plate, or both
In conclusion, a general statement regarding the optimal surgical treatment for cervical disc herniations using anterior approaches is difficult to make with this limited review. Surgeons ’ experience and familiarity with a particular approach are probably the most important factors in ensuring successful outcomes. (Source: Critical Reviews in Neurosurgery)

Prerequisites for fetal neurosurgery: management of central nervous system anomalies toward the 21st century
AbstractWith the dramatic technical advances in neuroimaging, it has become possible to diagnose central nervous system (CNS) anomalies in the fetus in utero with more precise morphological analysis. A new technique, high-resolution magnetic resonance (MR) imaging using heavily T2-weighted fast spin echo sequences, has been reported to solve motion artifact of the fetus. However, it has also been recognized that the morphological fetal CNS findings detected in early development are not always the final features: occasionally they may not be determined in diagnosis and may change developmentally or chronologically during th...

Interstitial irradiation with stereotactically implanted I-125 seeds for the treatment of cerebral glioma
AbstractOwing to its low rate of side effects and its high efficacy, interstitial irradiation with low-activity seeds should be the first therapeutic step in small (maximal diameter 40 mm), well-circumscribed, lowgrade gliomas affecting the brain stem, other midline structures, or eloquent cerebral areas. In anaplastic gliomas, a therapeutic schedule using low-activity seeds and combining interstitial irradiation with radiotherapy (reduced boost dose of 1530 Gy) seems to be more effective than interstitial irradiation alone. Compared with interstitial irradiation with high-activity seeds, this combined irradiation schedule...

Endovascular treatment of intracranial aneurysms: saccular aneurysms and posttraumatic pseudoaneurysms
AbstractThe endovascular treatment of intracranial aneurysms is gaining a definite place in neurosurgery. This is particularly true for using the Guglielmi detachable coil (GDC). “Endovascular treatment or direct surgery?” is a common discussion nowadays. The following papers raise some important issues with respect to this argument. This review also includes several papers that deal with posttraumatic pseudo aneurysms. One of the papers clearly suggests that endovascula r treatment could also play an important role in treatment treating pseudoaneurysms. (Source: Critical Reviews in Neurosurgery)
