Clinical Significance of the Cerebral Perforating Arteries.

There is scarce data in the contemporary literature regarding the correlation of the microanatomy of the perforating arteries, their atherosclerosis, and the ischemia in their territory. In order to examine, at least partially, those parameters, the perforating arteries of 12 brains were microdissected or their vascular casts were obtained. In addition, 30 specimens of the perforators were used for a histological and immunohistochemical study.

Decapitation in reality and fine art: A review.

The aim of our study was to examine all types of decapitation from forensic literature, including our own case, and to analyze the presentation of beheading in fine art, popular literature, and music. To do this, over 200 scientific articles in regard to decapitation were analyzed, as well as more than 10,000 artworks, and several hundreds of literary works and music pieces. In addition, a macroscopic examination of a decapitated victim was performed.

Comparative analysis of the animal model and results of the clinical research of the aneurysm inclination angle as the predisposing factor for the occurrence of rupture.

Introduction: Natural course of aneurysms that occur on blood vessels of the brain singles out the need for understanding the mechanism of the occurrence of aneurysm wall rupture and identification of anatomic characteristics as predictive factors for hemorrhage to occur.

Objective: In this study we comparatively present results of our researches and experimental models on animals.

Methods: We made a comparative analysis of anatomical characteristics of blood vessels of the brain and aneurysms obtained on the basis of digital subtraction angiography and intraoperative finding.

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.

[Comparative results of operative and endovascular treatment of intracranial aneurysms].

Therapeutic protoclol for intracranial aneurysm treatment is very complex. In depand od patient status and anviografic founding we determinate modality and time of treatment. Analysis included 137 patients who were treated in Neurosurgical clinic CCS because sponatenus subarachnoid haemorrhage rigine from aneurysm belading.

Natural course of the arteriovenous malformations of the brain initially presented by hemorrhage: analysis of a clinical series of 39 patients.

Aim: AVM because of outstanding tendency toward bleeding, even though 20 times more rare then aneurysm on the blood vessels of the brain and her own specific anatomical structure even today represents big neurosurgical challenge.

Material And Methods: Series which is shown here consists of 39 patients which were hospitalized in the institute for neurosurgery of the Clinical Center of Serbia in the period between 1995 and 2004. This group was exposed to symptomatic therapy or it was estimated that surgery, embolization and radio surgery.

Vasculature and neurovascular relationships of the trigeminal nerve root.

Background: Specific microanatomical characteristics of the trigeminal nerve root (TNR) blood supply and close neurovascular relationships with surrounding vessels as well as their possible clinical significance were the main reasons for this study.

Method: The vasculature of 25 adult and four fetal TNRs were microdissected and examined under the stereoscopic microscope, after injecting their arteries with India ink.

Results: The trigeminal vessels, which varied between two and five in number, arose from two or three of the following arteries: the superolateral pontine (92%), anterior inferior cerebellar (AICA) (88%), inferolateral pontine (72%), and superior cerebellar (SCA) (12%).

A retrospective analysis of anesthesiologic complications in pediatric neurosurgery.

Background And Objective: Different clinical and surgical factors can influence the occurrence of anesthesiologic complications in pediatric neurosurgery. Preoperative knowledge of these factors is of great importance in the application of safe anesthetics and a favorable surgical outcome. The objective was to establish the importance of clinical and surgical risk factors on the frequency of anesthesia complications in pediatric neurosurgery.

[The relation between the thickness of retrobulbar part of the optic nerve, measured by ultrasound, and the degree of prominence of the optic disc in stasis of the optic nerve].

Introduction: The etiology of the noninflamed edema of the optic disc, or the stasis of the same, is related to a large number of various illnesses which result in the increased intracranial pressure. When examining fundus, an edema of the optic disc is found which can be quantitatively expressed in diopters, while retrobulbar part of the optic nerve can be measured by ultrasonography.

Objective: The objective of our [Serbian characters: see text] is to explore the relation of the optic disc prominence and the degree of thickness of retrobulbar part of the optic nerve.

[Significance of the spatial reconstruction based on mathematical modeling in the surgical treatment of giant intracranial aneurysms].

Background: The use of computer models for the 3-dimensional reconstruction could be a reliable method to overcome technical imperfections of diagnostic procedures for the microsurgical operation of giant intracranial aneurysms.

Case Report: We presented a case of successfully operated 52-year-old woman with giant intracranial aneurysm, in which the computer 3-dimensional reconstruction of blood vessels and the aneurysmal neck had been decisive for making the diagnosis. The model for 3-dimensional reconstruction of blood vessels was based on the two 2-dimensional projections of the conventional angiography.

Combined treatment modality for anaplastic oligodendroglioma and oligoastrocytoma: a 10-year update of a phase II study.

Purpose: To provide updated outcome data (10 years) of a Phase II study of combined surgery, postoperative radiotherapy, and adjuvant chemotherapy in patients with anaplastic oligodendroglioma and oligoastrocytoma.
