#1
Suat Erol Çelik, Yavuz Samancı, Ferdi Özkaya, Olgün Peker
PURPOSE: Thoracic disk herniation (TDH) is relatively uncommon. The surgical approach differs from lumbar or cervical disk herniations because serious complications are associated with the posterior approach in TDH. Various different approaches have been tried for the surgical removal of TDH, but most of them are cumbersome surgeries such as thoracotomy or thoracoscopic or anterior approaches with or without instrumentation. The requirement for a simplified, familiar, and less morbid surgery has motivated some new approaches...

BACKGROUND:  Insertion of a frontal external ventricular drain (EVD) is a common emergency procedure in neurosurgery. Malpositioning of the EVD and/or triggering a new intracerebral or intraventricular hemorrhage (nICVH) are typical complications. The standard procedure (SP) uses a tape measure to identify the Kocher's point for placement of a frontal burr hole. A faster alternative to determine the correct position is the freehand technique (FHT). This study compared both techniques with regard to the correct positioning of the EVD tip and the induction catheter-induced nICVH...

BACKGROUND:  Paraplegia due to spinal combined subdural/subarachnoid hemorrhage is an extremely rare complication following percutaneous spinal augmentation procedures. METHODS:  A 63-year-old male patient presented with severe neurologic decline (paraplegia with sensory and autonomic dysfunction) resulting from a multilevel spinal subarachnoid hemorrhage shortly after bilateral kyphoplasty. RESULTS:  Reduction of intrathecal pressure via multiple dural and arachnoidal incisions and removal of the hematoma resulted in a good neurologic recovery with surgical decompression even though evacuation was performed with a significant delay after the onset of neurologic worsening...

Although deep brain stimulation (DBS) has been used for > 25 years in the treatment of movement disorders, no report has been published on the management of DBS pulse generators implanted in the anterior chest in patients with breast cancer who require mastectomy, radiotherapy, and future imaging studies.We describe a 62-year-old female patient with advanced Parkinson's disease (PD) who was dependent on bilateral subthalamic nucleus (STN) DBS. She was diagnosed with cancer in her left breast. To avoid difficulties in imaging studies, surgery, and radiotherapy related to the breast cancer, bilateral pulse generators for STN DBS previously implanted in the anterior chest wall were repositioned to the anterior abdominal wall with replacement of long extension cables...

BACKGROUND:  Intracranial chondromas are extremely rare and represent only 0.2% of all intracranial primary neoplasms. The histologic appearance lacks nuclear atypism and mitoses, and it usually shows low growth potential, although these benign features do not necessarily imply a good prognosis. CASE DESCRIPTION:  A 44-year-old man was referred to our institution with a subarachnoid hemorrhage (SAH). He had a history of SAH 5 years previously that was diagnosed as unknown etiology at another hospital...

BACKGROUND:  Although intraoperative motor-evoked potential (MEP) monitoring is widely performed during neurosurgical operations, evaluating its results is controversial. STUDY AIMS:  The cutoff point of MEP monitoring should be determined not only to predict but also to prevent postoperative neurologic deficits. MATERIAL AND METHODS:  MEP monitoring was performed during 484 neurosurgical operations for patients without definitive preoperative motor palsy including 325 spinal operations, 102 cerebral aneurysmal operations, and 57 brain tumor operations, all monitored by transcranial stimulation, and 34 brain tumor operations monitored under direct cortical stimulation...

BACKGROUND: Dissection and division of tissues are widely performed in microscopic neurosurgery, especially in brain tumor resection. Dissection maneuvers can be divided into two types: sharp dissection with microscissors and blunt dissection using a dissector. It is essential to use the appropriate method according to the intraoperative situation and conditions. Therefore, specific tools for each type of dissection maneuver are required. We developed an ultrasonic microdissector, a newly designed tool that functions as both microscissors and dissector to further advance brain tumor surgery...

Jiro Hirayama, Masayuki Hashimoto
BACKGROUND:  With effective preoperative planning, percutaneous endoscopic diskectomy (PED) via an interlaminar approach (PED-IL) can reduce the need for partial laminectomy. Our aim was to assess the clinical outcomes of PED-IL, planned using three-dimensional fusion of computed tomography and magnetic resonance (3D CT/MR) images. MATERIAL AND METHODS:  Our retrospective analysis was based on data from 102 patients (66 were men) treated by PED-IL. Preoperative planning was based on the positional relationship between the nerve root and the lumbar disk herniation, visualized on 3D CT/MR fusion images through a simulated IL window...

Transethmoidal encephalocele is a rare condition in adult patients. It is usually diagnosed during childhood by cerebrospinal fluid (CSF) rhinorrhea, meningitis, a nasal mass, or seizures. We present a case of an adult woman with CSF rhinorrhea following resection of an occipital meningioma. The cribriform plate defect containing the encephalocele was diagnosed by computed tomography and magnetic resonance imaging. Transcranial surgery using a patch was performed successfully. We also discuss the possible pathophysiologic mechanisms of encephalocele and treatment options...

Lhermitte-Duclos disease is a rare condition with less than 250 cases reported in the literature. It was considered a neoplastic or hamartomatous growth in the cerebellum. It commonly presents with symptoms of high intracranial pressure or obstructive hydrocephalus. Surgical resection is often curative. The lesion is associated with PTEN gene mutation, and it is considered to be one of the diagnostic criteria of Cowden's syndrome. Vascular tumors are reported in this syndrome, including glioblastomas and meningiomas...

OBJECTIVES:  Ventriculoperitoneal (VP) shunting is commonly used to treat pediatric hydrocephalus, but failure rates are high. VP shunt failure in children is mostly caused by infection and/or proximal/distal shunt obstruction. However, to our knowledge, no previous reviews have discussed this topic using only clinical studies when age-related data could be obtained. This systematic review aimed at reevaluating what is already known as the most common causes of shunt failure and to determine the incidence and causes of VP shunt failure during the first 2 years of life as a step to establish solid evidence-based guidelines to avoid VP shunt failure in infants...

Seyho Cem Yucetas, Necati Ucler
Alkaptonuria is a rare metabolic disease caused by deficiency of homogentisic acid oxidase and characterized by bluish-black discoloration of cartilages and skin (ochronosis). Defective production of this enzyme results in the accumulation of homogentisic acid (HGA), a tyrosine degradation product, in the bloodstream. Accumulation of HGA and its metabolites in tissues causes ochronosis. The word ochronosis refers to the dark bluish-black discoloration of connective tissues including the sclera, cornea, auricular cartilage, heart valves, articular cartilage, tendons, and ligaments...

BACKGROUND: Superficial temporal artery to middle cerebral artery (STA-MCA) bypass is a treatment option for hemodynamic insufficiency in the anterior cerebral circulation. Complications associated with extracranial-intracranial bypass surgeries are ischemic strokes caused by bypass failure, wound-healing disorders, and further issues from cerebrospinal fluid (CSF) leakage. CSF leakage can provide pathways for infection. It is well known in general neurosurgery that watertight closure of the dura mater is necessary to prevent such complications...

BACKGROUND AND STUDY AIMS:  Computed tomography (CT) and magnetic resonance image (MRI) data have been widely used to for navigation in various neurosurgical operations. However, delicate intracranial structures cannot be displayed using only one imaging method. Navigation with multimodality imaging was developed to better visualize these structures in glioma removal, but whether it is useful in endoscopic transsphenoidal surgery is unknown. We describe our clinical experience using multimodality imaging for navigation in endoscopic transsphenoidal surgeries...
