Simultaneous and Consecutive Drainage of Bilateral Chronic Subdural Hematoma: A Randomized Controlled Trial.

Chronic subdural hematoma (CSDH) is one of the most common types of intracranial hemorrhage, particularly in elderly individuals. Although most patients present with unilateral CSDH, bilateral involvement is not rare. Furthermore, bilateral CSDHs are associated with rapid deterioration and poorer outcomes because of a higher risk of brain herniation than unilateral hematomas.

A case of rare lumbar intradural tumor: paraganglioma.

Lumbar paragangliomas are rare neuroendocrine neoplasms arising from specialized neural crest cells in the cauda equina/filum terminale region. They are difficult to diagnose radiologically and can be difficult to treat surgically if they secrete catecholamines. A 38-year-old woman presented with three and a half years of increasing lower back and sacrum discomfort.

Dexamethasone Addition Impairs the Therapeutic Effects of Nimodipine for Subarachnoid Hemorrhage: An Experimental Animal Study.

Aim: To evaluate the effects of the combination of nimodipine and dexamethasone in subarachnoid hemorrhage (SAH).

Material And Methods: In this study, 35 female adult Wistar Albino rats were randomly assigned to four groups: Sham (n=8), SAH with no treatment (n=9), SAH with nimodipine (n=9, oral gavage, 12 mg/kg, BID) treatment, and SAH with combined therapy with nimodipine and dexamethasone (n=9, intraperitoneally, 1mg/kg, BID). The "cisterna magna double injection of autologous blood" model was used.

Women in Neurosurgery: Turkey's Yıldız Yalçınlar.

Background: Severalreports have been published on the history of pioneering women pursuing neurosurgery. Women in Turkey started receiving neurosurgery specialty training later than men, as was the case in other parts of the world. However, compared to other countries, Turkey saw the admission of women in neurosurgery sooner, with Aysima Altınok who obtained her specialization in 1959.

A True Percutaneous Anterior Odontoid Screw Fixation: The Results of 42 Cases by a Single Surgeon.

Objective: This study aimed to analyze a clinical series of odontoid fractures treated with true percutaneous anterior odontoid screws. The technique we used is different from the traditional approach of using blunt dissection to arrive at the anterior surface of the vertebral body.

Methods: Between 2004 and 2021, forty-two patients underwent anterior screw fixation of the odontoid process using the true percutaneous technique without dissection among the fascial planes.

Evaluation of Incidentally Detected Pathology Results of Patients with Vertebral Fracture Treated by Vertebroplasty and Kyphoplasty: A Retrospective Study.

Background: Vertebroplasty and kyphoplasty are minimally invasive techniques used to treat vertebral compression fractures. The etiology of vertebral compression fractures varies among patients. Although osteoporosis and trauma are major etiologic factors in patients with a vertebral compression fracture, unexpected results were found in 11 patients in the present study.

Double-layer appearance after evacuation of a chronic subdural hematoma.

Objective: To investigate the reason for and the course of the double-layer appearance in the postoperative computed tomographies (CTs) of chronic subdural hematoma (CSDHs).

Methods: We reviewed CSDH cases that were operated on during the last 3 years, between January 2008 and December 2010. We checked the preoperative, early postoperative, and late postoperative CTs of these patients.

Prevention of anterior scar formation following discectomy with a MediShield adhesion barrier: randomized experimental trial.

Aim: To investigate whether carboxymethylcellulose/polyethylene oxide (CMC/PEO) gel has a protective effect against epidural scar formation anterior to the dura following discectomy.

Material And Methods: A barrier gel comprised of CMC and PEO (MediShield) was studied as a material to reduce anterior epidural scar formation in a rabbit laminotomy and discectomy model. After laminotomy and disc puncture, the surgical side was either treated with MediShield or used as a surgical control, as determined by random allocation.

Brucellar spondylodiscitis: comparison of patients with and without abscesses.

Brucellosis is an important cause of spondylodiscitis in endemic areas. Brucellar spondylodiscitis is a serious complication because of its association with abscess formation. Prospective studies comparing patients with and without abscesses are lacking.

Partial spondylectomy for primary leiomyosarcoma of C2 vertebra.

Study Design: A primary leiomyosarcoma located on the left side of the C2 is reported. Left-sided partial spondylectomy and anterior reconstruction with posterior stabilization was performed by a two-staged operation.

Objective: To emphasize the occurrence of primary leiomyosarcoma and the importance of proper stabilization in the upper cervical spine.

Hemifacial spasm in correlation with electrophysiological and radiological findings.

Objective: To investigate the correlation between the electrophysiological and radiological findings of primary hemifacial spasm patients.

Subjects: Patients with primary hemifacial spasm who had had no botulinum toxin treatment previously were included in the study.

Design: In this prospective study patients underwent cerebral magnetic resonance imaging,a magnetic resonance angiography investigation and an electrophysiological examination after informed consent had be given by the patients.

Nasal-subfrontal giant schwannoma.

Subfrontal schwannomas are rare lesions. They can be misdiagnosed as olfactory meningiomas or neuroblastomas. We report a case of giant schwannoma involving the anterior cranial fossa; the frontal and ethmoid sinuses and nasal cavities.

Is it possible to start the treatment based on immediate cytologic evaluation of core needle biopsy of the spinal lesions?

Core needle biopsy is widely used to diagnose spinal lesions. Final histopathological report of the specimen usually can be given after several days. These several days delay may prevent early treatment in some patients.

Can midline brain shift be used as a prognostic factor to predict postoperative restoration of consciousness in patients with chronic subdural hematoma?

Background And Purpose: Our aim was to determine if midline brain shift could be used as a prognostic factor to predict postoperative restoration of consciousness in patients with CSDH. In these patients, we evaluated the relation (1) between midline brain shift as measured on CT and alteration of level of consciousness, and (2) between midline brain shift and restoration of consciousness after the operation.

Methods: Prospectively recorded data of 45 patients with CSDH were evaluated.

Percutaneous computed-tomography-guided biopsy of the spine: 229 procedures.

Objectives: Percutaneous biopsy of the spine is an effective and well-evaluated procedure. Only very few series containing more than a hundred patients have been reported so far and there is no agreement about the factors affecting the diagnostic rate. We aimed to find out if there is any factor influencing the success rate of the spinal biopsy using our biopsy series.

Primary rhabdoid tumor of the brain in an adult.

Rhabdoid tumor (RT) is an uncommon childhood neoplasm that typically arises within the kidney. It is characterized by an aggressive clinical course. Since its description in 1978, several cases of primary extrarenal RT, including a CNS localization, have been reported.

Lumbar disk herniation with contralateral symptoms.

The aim of the study is to determine if leg pain can be caused by contralateral lumbar disk herniation and if intervention from only the herniation side would suffice in these patients. Five patients who had lumbar disk herniations with predominantly contralateral symptoms were operated from the side of disk herniation without exploring or decompressing the symptomatic side. Patients were evaluated pre- and postoperatively.

The value of XYZ/2 technique compared with computer-assisted volumetric analysis to estimate the volume of chronic subdural hematoma.

Background And Purpose: A simple estimation method of intracerebral hematoma volume known as XYZ/2 method has been described previously. This method has also been shown to be valid for the estimation of acute subdural hematoma volume. However, chronic subdural hematomas differ in shape and extension from acute subdural hematomas, which makes the validity of the same method in the estimation of hematoma volume questionable.

Combined approach for otogenic brain abscess.

Otogenic intracranial infections usually require both neurosurgical and otolaryngological surgery. This prospective, non-randomized study investigated the value of combining both surgical procedures. Thirteen patients with otogenic intracranial abscess were treated by mastoidectomy and abscess removal through the same incision between 1993 and 2002.

Computerized tomography-guided percutaneous transforaminodiscal biopsy sampling of vertebral body lesions.

Object: The posterolateral approach is the common route for obtaining percutaneous biopsy samples in lumbar and thoracic vertebral bodies (VBs). This procedure, however, is associated with the risk of complications. Because of this, the authors devised a new method for percutaneous biopsy sampling of VB lesions.
