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)
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)
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.
AIM The authors compared the incidence of radiologically documented and/or symptomatic adjacent segment degeneration in and between patients who underwent anterior or posterior single-level, simple discectomy. MATERIAL AND METHODS 79 patients were clinically and radiologically examined for adjacent segment degeneration (ASD). The results were compared to(More)
Retroclival arachnoid cysts are rarely reported. A 40-year-old woman had a sudden onset of occipitocervical pain. Magnetic resonance imaging (MRI) revealed a cystic mass lesion located in the retroclival region and complicated with intracystic haemorrhage. At operation, by a right lateral suboccipital approach, an old, intracystic haemorrhage was aspirated(More)
Non-traumatic multiple saccular aneurysms of the middle meningeal artery are extremely rare lesions. In our case the patient was a 51-year-old woman admitted with complaints of progressive headache. Magnetic resonance imaging showed a dilatation of the vein of galen malformation. Cerebral angiography revealed multiple saccular aneurysms of the middle(More)
