BACKGROUND The incidence of chronic hydrocephalus requiring shunt placement is a well-known and common complication of aneurysmal subarachnoid hemorrhage (aSAH). It was suggested that fenestration of the lamina terminalis (LT) during microsurgery for aSAH may be associated with a reduced rate of shunt-dependent chronic hydrocephalus (SDCH). We analyzed(More)
INTRODUCTION We retrospectively evaluated computed tomography angiography (CTA) and perfusion imaging (CTP) of patients with aneurysmal subarachnoid hemorrhage (SAH) for any correlation between degree of vasospasm and perfusion deficit. MATERIALS AND METHODS Sequentially performed CTP and CTA of 41 patients at least at the third day of postbleeding were(More)
BACKGROUND Intraventricular hemorrhage and posthemorrhagic hydrocephalus are common causes of neonatal morbidity and mortality among preterm and low-birth weight infants (PT-LBWIs). Clinical management of posthemorrhagic hydrocephalus (PHH) is difficult and not well standardized. In this study, we aimed to determine the incidence of hydrocephalus after(More)
One of the aims of neuroanesthesia is to provide early postoperative recovery and neurologic examination in patients undergoing supratentorial surgery. Our aim was to investigate the role of using the bispectral index (BIS) in recovery from anesthesia and altering drug administration in patients undergoing craniotomy. Fifty American Society of(More)
Decompressive surgery or craniectomy (DC) is a treatment option, which should be considered when the intracranial pressure (ICP) cannot be treated by conservative methods. The purpose of this study was to evaluate the benefits of decompressive craniectomy in patients with intractable posttraumatic intracranial hypertension and to evaluate the patient(More)
The most common site of cerebrospinal fluid (CSF) leakage is through the floor of the anterior fossa, which communicates with the ethmoid or frontal sinuses or with the nasal fossa. The sphenoid sinus is rarely implicated as a source of spontaneous CSF fistula. Transclival meningocele is an extremely rare lesion. A 36-year-old woman with a 1-year history of(More)
Temporal meningocele is a rarely encountered pathology. It is caused by communication between the subarachnoid space of the middle fossa and lateral extension of the sphenoid sinus. Cerebrospinal fluid (CSF) pressures and the hydrostatic pulsatile forces may lead to the development of pitholes on the middle fossa at the sites of arachnoid villi with(More)
AIM Debate continues as to whether decompressive craniectomy (DC) is an effective treatment for severe traumatic brain injury (STBI). DC is mostly used as a second tier treatment option. The aim of this study was determined whether early bilateral DC is effective as a first tier treatment option in patients with STBI. MATERIAL AND METHODS The study(More)
BACKGROUND After surgery for ruptured anterior communicating artery (ACoA) aneurysm, several patients who have achieved a favorable neurological outcome yet have been observed to suffer from a poor cognitive outcome. The aim of this study was to explore the possible effects of temporary clip applications on frontal lobe functions in the patients with(More)
Intradural spinal lipomas of thoracic cord are quite rare. It is known that lipomas are hamartomas, which change their size with alterations of body fat. An 18-year-old male patient, with a thoracic intradural lipoma showing spontaneous decrease in the size of a residual lipoma and tethering of the cord 4 years after surgery, is presented in this report.
