Masoud Shirvani, Alireza Hajimirzabeigi
Intraventricular cavernomas (IVCs) are extremely infrequent and only occur in 2.8 to 10% of patients with cerebral cavernomas. We describe three IVC cases and briefly review previously documented IVC cases in PubMed. Among 136 IVC cases, the mean age of the patients was 36.5 years; the male-to-female ratio was 0.8. The most frequent location was the lateral ventricle (52.6%), and most of the clinical symptoms (74%) were related to mass effects on adjacent brain tissues. Intraventricular hemorrhage occurred in 22...

Background The main symptoms of degenerative lumbar spinal canal stenosis are progressive back pain, spinal claudication, and, occasionally, sensory and motor deficits. Impairments particularly occur during walking, standing, and sitting. Thus social and vocational activities are increasingly restricted, causing considerable suffering for patients. Surgical therapies are superior to conservative ones. This article studies the outcome of 2-level fenestration versus hemilaminectomy for bisegmental spinal stenosis decompression...

Background and Study Aims It was suggested that emergency operations could represent a risk factor for complications. The purpose of this study was to evaluate whether complication rates are higher in emergency lumbar disk operations compared with elective lumbar disk surgery. Materials and Methods Patient data sets from 575 microscopic lumbar disk surgeries performed within a 5-year period were evaluated in a retrospective study design. There were 498 patients after excluding those who had surgery for recurrent disk herniation...

Background In experimental models of neuronal damage, therapeutic hypothermia proved to be a powerful neuroprotective method. In clinical studies of traumatic brain injury (TBI), this very distinct effect was not reproducible. Several meta-analyses draw different conclusions about whether therapeutic hypothermia can improve outcome after TBI. Adverse side effects of systemic hypothermia, such as severe pneumonia, have been held responsible by some authors to counteract the neuroprotective effect. Selective brain cooling (SBC) attempts to take advantage of the protective effects of therapeutic hypothermia without the adverse side effects of systemic hypothermia...

Background Ameloblastomas are a rare tumor entity accounting for only 10% of all odontogenic tumors. They mostly originate from the mandible. Only a few cases are known to grow aggressively and to invade the orbit, nasal cavity, or even the brain. Patient and Methods/Case Report We present the case of a 57-year-old patient who was admitted with a huge tumor involving the nasal cavity, the left maxilla, and the anterior fossa. Histologic diagnosis was made by biopsy. A combined two-stage neurosurgical maxillofacial approach was planned...

Chaoran Xie, Xuesheng Zheng, Nu Zhang
Background In clinical practice, we noted that the end section of the thecal sac is apparently different in patients with Tarlov cyst compared with that of the normal population. We conducted this clinical study based on magnetic resonance imaging (MRI). Methods Our study included 30 patients with Tarlov cyst and 30 healthy volunteers as the control. The L4, L5 cross-section areas, the L4, L5 anteroposterior diameters, and the terminal length of the thecal sac were measured from the lumbosacral spine MRI...

Introduction Posterior midline laminectomy is associated with risks of postoperative instability, spinal deformity, extensive bilateral subperiosteal muscle stripping, partial or total facetectomy especially in foraminal tumor extension, increased cerebrospinal fluid leakage, and wound infection. Minimally invasive approaches with the help of a microscope or endoscope using hemilaminectomy have been found to be safe and effective. We report our initial experience of 18 patients using the endoscopic technique...

Traumatic aneurysm rupture following a closed head injury is rare. The rupture of a cavernous internal carotid artery (ICA) aneurysm following a head injury presenting as a tentorial subdural hematoma has not been reported in the literature. We discuss a 50-year-old woman with a closed head injury with her initial computed tomography scan showing a tentorial subdural hematoma. Further investigations revealed the presence of a ruptured cavernous ICA aneurysm. We also conducted a literature review of posttraumatic ICA aneurysmal rupture...

Objective Osteochondroma (OC) is the most common benign bone neoplasm. It infrequently occurs in the cranial cavity as a calcified lesion and very rarely presents in the sellar region. The present study summarizes the knowledge about OCs of the sellar region. Methods We searched the literature search for the clinical appearance of OCs and other calcified pathologies occurring in the sellar region. Results A total of 21 English-language articles published from 1961 to 2015 documented cases of calcified lesions in the sellar region including cerebral aneurysm, chondroid chordoma, chondroma, craniopharyngioma, OC, odontome, osteoma, pituitary adenoma, pituitary stone, Rathke cleft cyst, retinoblastoma, schwannoma, and xanthogranuloma...

Spasticity of cerebral or spinal origin severely impairs an individual's functional ability and quality of life. Intrathecal baclofen (ITB) therapy via an implantable pump is indicated for use in patients unresponsive to oral antispasmodics. ITB therapy improves the daily caring for and relief of painful spasms. In Lithuania, ITB therapy was introduced in clinical practice just recently. We share our experience of spasticity management with the ITB pump system in five patients at Vilnius University Hospital Santariskiu Klinikos...

Background The piezo actuator-driven pulsed water jet (ADPJ) system is a novel surgical instrument that enables dissection of tissue without thermal damage. Using the ADPJ system in epilepsy surgery requires prediction of the tissue breaking strength of the epileptic brain. The aim of this study was to elucidate whether magnetic resonance imaging T2 relaxometry could predict the breaking strength. Methods A total of 12 patients with drug-resistant temporal lobe epilepsy who received surgical treatment were included in the study...

Introduction Efficient neurosurgical training is of paramount importance to provide continuing high-quality medical care to patients. In this era of law-enforced working hour restrictions, however, maintaining high-quality training can be a challenge and requires some restructuring. We evaluated the current status of resident training in Germany. Methods An electronic survey was sent to European neurosurgical trainees between June 2014 and March 2015. The responses of German trainees were compared with those of trainees from other European countries...

Introduction Previous studies have suggested relationships between the rupture of intracranial aneurysms and meteorological variables such as season, barometric pressure, and temperature. Our objective was to examine the relationship between the incidence of hospital admissions secondary to aneurysmal subarachnoid hemorrhage (aSAH) and meteorological variables in central New Jersey. Methods The study population consisted of 312 patients who presented to University Hospital in Newark, New Jersey, between January 1, 2003, and December 31, 2008, with aSAH...

We report a misinterpretation of bilateral mydriasis as blown pupils related to elevated intracranial pressure (ICP) under volatile sedation with isoflurane (Anesthetic Conserving Device [AnaConDa], Hudson RCI, Uppland Vasby, Sweden) in a 59-year-old patient with a severe traumatic brain injury with frontal contusion. The patient showed bilateral mydriasis and a missing light reflex 8 hours after changing sedation from intravenous treatment with midazolam and esketamine to volatile administration of isoflurane...

Background The treatment of brain arteriovenous malformations (AVMs) has been studied extensively. With the use of the Spetzler-Martin (S-M) grading system, patients can be informed appropriately about their possible surgical risks. This does not hold true for their neuropsychological sequelae, which have not been studied widely. We evaluated the neuropsychological outcome of our patients treated for brain AVMs. Methods Of 113 patients treated for a brain AVM between 2001 and 2009, 66 patients were enrolled in the study...

Objective The transfemoral approach is a common route for catheterization of the supra-aortic vessels in neuroendovascular therapy. However, in some cases, the patient's anatomy prevents transfemoral catheterization or distal access to the carotid s. In such cases, direct carotid exposure (DCE) for neuroendovascular approaches may be used to treat cerebrovascular diseases. Methods We present 11 cases in which we were unable to perform the distal approach and DCE was the preferred neuroendovascular treatment procedure...
