Pineal Tumor Surgery-The Choice of the Approach Related to Tumor Characteristics and Posterior Fossa Anatomy.

Objective: This research aimed to determine whether an adequate surgical approach can be chosen based on clearly defined values of anatomical landmarks (tentorial angle) and tumor size and extension.

Methods: We conducted a retrospective analysis of patients operated on because of pineal tumors. The cohort was divided depending on the surgical approach.

Reconstruction of Moderately and Severely Atrophic Scalp-A Multicentric Experience in Surgical Treatment of Patients Irradiated for Tinea Capitis in Childhood and Surgical Algorithm.

: Before the introduction of griseofluvin, the use of X-ray radiation was the treatment of choice for tinea capitis. More than half a century later various types of tumors have been found to be associated with childhood irradiation due to tinea capitis, most commonly cancers of the head and neck, as well as brain tumors. The often unusually aggressive and recurrent nature of these tumors necessitates the need for repeated surgeries, while the atrophic skin with an impaired vascular supply due to radiation often poses an additional challenge for defect reconstruction.

Transorbital hybrid approach for endovascular occlusion of indirect carotid-cavernous fistulas-Case report and systematic literature review.

Carotid-cavernous fistulas (CCF) are vascular malformations characterized by an aberrant shunt between one or more sources of arterial inflow and the cavernous sinus (CS). They are subdivided into direct and indirect fistulas. This last one, called dural CCF involve dural fistulous connections between branches of the internal carotid artery or the external carotid artery.

Effects of subchronic methionine stimulation on oxidative status and morphological changes in the rat ileum.

This study was conducted to explore the effects of sulfur containing amino acids on redox status and morphological parameters in the rat ileum tissue. Male Wistar albino rats were randomly divided into the following groups: Group K (saline (1 ml/day, i.p.

Determination of Predictive Anatomic Parameters for Bleeding of Brain Arteriovenous Malformations by Multidetector CT Angiography.

Patients with brain arteriovenous malformation (AVM) have a certain risk to bleed, and the goal of this study was to examine the effect of radiological and clinical predictive characteristics of AVM hemorrhage using multidetector computed tomographic (MDCT) angiography. The study included a series of 57 patients, mean age 35.46 years, who were diagnosed during their hospitalization at Clinical Department of Neurosurgery, Clinical Center of Serbia, in the period from January 2008 to March 2016.

Suppression of methionine-induced colon injury of young rats by cysteine and N-acetyl-L-cysteine.

Changes in the methionine metabolism can cause a state called hyperhomocysteinemia, inducing oxidative stress in the gut. The production of free radicals is important in the colon damage caused by methionine. This study aimed at evaluating the effect of the use of L-cysteine and N-acetyl-L-cysteine on the colon morphometry of young rats treated with methionine.

Adult Brainstem Gliomas: Retrospective Analysis of 51 Patients.

Aim: Brainstem gliomas (BSG) constitute less than 2% of brain tumors in adults. Therapeutic options are limited and BSG are associated with a high morbidity and mortality.

Material And Methods: We reviewed the records of 51 patients with BSG treated at the Institute of Neurosurgery, Clinical Center of Serbia in Belgrade between 1998 and 2012.

GLIOBLASTOMA MULTIFORME BRAIN TUMORS LOCATED IN THE MOTOR CORTEX--SPECIFIC FINDINGS IN COMPARISON WITH LOW GRADE GLIOMAS OF THE SAME LOCALIZATION: ANALYSIS OF A SIXTY PATIENT SERIES.

The verified presence of a glioblastoma multiforme (GBM) tumor in the motor area of the brain, in a patient lacking preoperative neurological deficit, offers no certainty that the tumor can be radically removed without the possibility of causing postoperative motor deficit. We present a series of 60 patients hospitalized at the Clinical Department of Neurosurgery, Clinical Center of Serbia in Belgrade between October 2011 and February 2015, harboring tumors located within and in the vicinity of the motor zone of the brain. By using Karnofsky's index (KI), the pre- and postoperative conditions of the patients were evaluated.

Assessing the quality of angiographic display of brain blood vessels aneurysms compared to intraoperative state.

Background/aim: Aneurysms in brain blood vessels are expanding bags composed of a neck, body and fundus. Clear visibility of the neck, the position of the aneurysm and surrounding structures are necessary for a proper choice of methods for excluding the aneurysm from the circulation. The aim of this study was to evaluate the reliability of spatial reconstruction of blood vessels of the brain based on the original software for 3D reconstruction of the equipment manufacturer and a personal computer model developed earlier in the Clinic for Neurosurgery, Clinical Center of Serbia, Belgrade, compared to intraoperative identification of these aneurysms.

Surgical treatment problems of hydrocephalus caused by spontaneus intraventricular hemorrhage in prematurely born children.

Aim: The aim of this study was to identify the most appropriate method of surgical treatment of hydrocephalus in preterm infants that is caused by spontaneous intraventricular hemorrhage (IVH) and to identify predictive factors of poor perioperative outcomes.

Material And Methods: We present a series of 60 patients with IVH and hydrocephalus, to whom a VP shunt or subcutaneous (Omaya) reservoir was placed, during the period from March 2006 to March 2011.

Results: Predictors of poor outcome with VP shunt placement were: gestational age (t=2.

Application of the Ommaya reservoir in the treatment of hydrocephalus in prematurely born children: correlation with animal results.

Introduction: Intraventricular hemorrhage occurs in almost one fifth of prematurely born children. Due to present complications, such as hydrocephalus and neurological deficit, it endangers the child's life, therefore there is the need for understanding and prevent risk factors as well as the need for finding most optimal methods of treatment.

Objective: The aim of the study was to point out the current therapeutic modalities of the treatment of posthemorrhagic hydrocephalus in prematurely born children.

The results of treatment of primary brain tumors in children.

During the period of 2009-2011 in UCH in Belgrade, we treated 22 patients with brain tumors. Treatment included the diagnosis and therapy that included surgery and postoperative neuroradiological follow-up of all patients regardless of whether radiotherapy was conducted with or without chemotherapy. The most frequent were low grade astrocytomas and medulloblastomas.
