Rosette-forming glioneuronal tumour (RGNT) of the fourth ventricle is one of the newly described primary tumours of the central nervous system. These tumours have two components of both neurocytic and glial areas but usually the glial component of the tumour predominates. They have biphasic cytoarchitecture with two elements; neurocytic rosettes resembling Homer-Wright rosettes, and astrocytic ...

Left ventricular (LV) untwisting starts early during the isovolumic relaxation phase and proceeds throughout the early filling phase, releasing elastic energy stored by the preceding systolic deformation. Data relating untwisting, relaxation, and intraventricular pressure gradients (IVPG), which represent another manifestation of elastic recoil, are sparse. To understand the interaction between...

PURPOSE OF REVIEW Pleural effusions have a major impact on the cardiorespiratory system. This article reviews the pathophysiological effects of pleural effusions and pleural drainage, their relationship with breathlessness, and highlights key knowledge gaps. RECENT FINDINGS The basis for breathlessness in pleural effusions and relief following thoracentesis is not well understood. Many existi...

BACKGROUND Heart transplantation in patients supported with ventricular assist devices (VADs) entails a high risk of injury at resternotomy. Prior femorofemoral bypass is the preferred approach in these patients, but poor venous drainage may restrict arterial flow rate. PATIENTS AND METHODS We compared bypass parameters, transfusion requirements and postoperative outcome in 33 consecutive pat...

Background and Purpose: The objective was to analyze the feasibility of an External Ventricle Drainage (EVD) for an obstructive hydrocephalus in patients with severe ventricular hemorrhage. Methods: In this retrospective study, from October 2012 to January 2014 in our department, 23 patients received an EVD for obstructive hydrocephalus. The duration of required EVD, risk factors, and therapeut...

OBJECTIVE To evaluate hemodynamics in patients with severe traumatic brain injury (TBI) after cerebral perfusion pressure (CPP) management using cerebrospinal fluid (CSF) drainage. METHODS Twenty-six patients with TBI (Glasgow Coma Score = 8 or less) were investigated. Mean arterial blood pressure, CPP, cardiac index (CI), systemic vascular resistance index (SVRI), and central venous pressure...

Placement of external ventricular drainage (EVD) catheters is the gold standard for managing acute hydrocephalus, but the range of complications varies in different studies. The objective of this present single institute study is to analyze iatrogenic factors, which may influence the EVD device placement and the patient's outcome. A total of 137 EVD placements in 120 patients at the University ...
