Coincidence of Tethered Cord, Filum Terminale Lipoma, and Sacral Dural Arteriovenous Fistula: Report of Two Cases and a Literature Review.

Spinal dural arteriovenous fistula (SDAVF) is the most common vascular malformation of the spine in adults. However, the coincidence of tethered cord syndrome, lipoma, and SDAVF on the sacral level is exceptionally rare. We describe two patients, probably the fifth and sixth ever reported.

Levels of selected pro- and anti-inflammatory cytokines in cerebrospinal fluid in patients with hydrocephalus.

Importance of Radiological Evaluation of Global Spinal Balance Together with Lower Limb Alignment in Planning Lumbar Spine Deformity Surgery - Illustrative Case Presentation.

Background: The presented case illustrates the critical role of a detailed preoperative radiological evaluation in complex spine surgery.

Case Report: A 49-year-old patient was admitted for a revision surgery after L3-L5 fusion. Preoperative assessment showed preserved sagittal balance, coronal imbalance and valgus knee deformity.

Executive functioning pattern as a prognostic indicator for shunt implantation surgery in patients with normal pressure hydrocephalus - A preliminary report.

The problem of executive functions in patients with normal pressure hydrocephalus (NPH) was investigated in the study. Executive function parameters were assumed to be among factors that may differentiate the clinical pattern in NPH. Two major indicators of executive functioning, i.

Decompressive craniectomy in trauma: when to perform, what can be achieved.

Subject: The goal of the study was to evaluate the effectiveness of the decompressive craniectomy (DC) concerning its various parameters.

Material And Methods: Forty-five patients were studied (6 female, 39 male, mean age 53 years). All patients were treated because of severe traumatic brain injury.

The impact of Pleurotus ostreatus on organic matter transformation processes.

This study showed the effect of Pleurotus ostreatus on the external organic matter (OM) transformation processes. The kinetics of these changes were determined. The experiment was conducted as 42-day pot experiment done in four combinations (with four replications).

Cerebrovascular reactivity evaluated by transcranial doppler sonography in patients after aneurysmal subarachnoid haemorrhage treated with microsurgical clipping or endovascular coiling technique.

Objective: To examine cerebrovascular reactivity in patients after subarachnoid haemorrhage (SAH) during long-term follow-up, using Acetazolamide test and transcranial Doppler (TCD) monitoring of blood flow velocities (BFVs), to compare of CO(2) reactivity between patients after SAH treated with three different methods: surgical (clipping), endovasculary (coiling) and conservative.

Methods: The study was performed in a group of 24 patients treated for SAH. Cerebrovascular reactivity (CVR) has been evaluated after intravenous administration of 1000 mg of Acetazolamide.

A non-invasive assessment of intracranial volume reserve by measuring cerebrospinal fluid volume with the aid of CT imaging.

Introduction: Monitoring changes in the intracranial volume (ICV) reserve and intracranial pressure (ICP) is one of the key issues in the treatment of intracranial pathologies. The aim of this study is to develop a method of monitoring the ICV reserve by analyzing CSF volume measured using CT in specific regions.

Materials And Methods: A total of 20 patients with cerebral injury were evaluated.

A new CT-based classification of spontaneous supratentorial intracerebral haematomas.

Background And Purpose: In patients with intracerebral haematoma (ICH) secondary to ruptured aneurysm or arteriovenous malformation (AVM), conservative therapy and follow-up without angiographic evaluation is associated with a risk of recurrent bleeding. It is necessary for a clinician to identify a subgroup of patients with spontaneous supratentorial ICH who are likely to harbour high-flow vascular malformations that require specific treatment - neurosurgical or neuroradiological. A new CT-based classification for supratentorial ICH aimed at a close correlation between ICH localization and occurrence of high-flow vascular malformations diagnosed on angiography is presented.

Early cerebral hemodynamic alternations in patients operated on the first, second and third day after aneurysmal subarachnoid hemorrhage.

Surgery timing after aneurysmal subarachnoid hemorrhage (SAH) may influence the risk of vasospasm after early surgical procedure and is correlated with SAH extensiveness. A group consisting of 127 patients with aneurysmal SAH was studied. The changes of mean flow velocity (MFV) were measured in middle cerebral artery (MCA) and in anterior cerebral artery (ACA) by transcranial Doppler sonography (TCD) in three groups of patients divided according to the surgery timing (on the first, second and third day after SAH).

[Diagnostic difficulties due to atypical symptoms in normal pressure hydrocephalus. A case report].

This paper presents a case of a female patient with unusual symptoms of diagnosed hydrocephalus. Symptoms demonstrated by the patient were initially diagnosed as immature personality, after that she was diagnosed with reactive depressive disorders. For those reasons she was treated for over 20 years in different psychiatric outpatient clinics and psychiatric hospitals.

Cerebrospinal fluid free-radical peroxidation products and cognitive functioning patterns differentiate varieties of normal pressure hydrocephalus.

The aims of the study were as follows: first, to verify the hypothesis that free radical peroxidation may be one of the factors implicated in pathophysiology of normal pressure hydrocephalus (NPH) and, second, to find out whether these biochemical characteristics together with neuropsychological cognitive deficits can differentiate between various types of NPH. This provides prognostic criteria for selection of patients for shunt surgery. Lipid peroxidation was measured in terms of thiobarbituric acid-reactive material (TBAR) and protein sulphydryl (SH) groups were measured as CSF content.

[The first system of image transmission and neurosurgical telecommunication in Poland].

Objective: The goal was to develop a fast and efficient neurosurgical teleconsulting network to improve acute neurosurgical patient care, to reduce transport costs and unnecessary occupation of neurosurgical beds.

Methods: Modems with 56 kilobits/s data transmission speed are used. CT images are transmitted straight from CT scanner via modem/telephone lines to receiving personal computer in Department of Neurosurgery.
