OBJECTIVE: A pseudomeningocele and an incisional cerebrospinal fluid leak are considered frequent complications following neurosurgical operations. The rate of these complications especially increases following neurosurgical procedures on the posterior cranial fossae. According to some publications, the rate of pseudomeningoceles has been reported as high as 40%, whereas that of incisional cerebrospinal fluid leaks is up to 17%. For the purposes of reducing the risk of these complications after a midline suboccipital craniotomy, we propose suturing the arachnoid membrane of the cisterna magna...

BACKGROUND: Cranioplasty is considered a low-risk operation in the field of neurosurgery following decompression craniectomy (DC). Well-known complications after cranioplasty, such as infection, seizure, and titanium plate exposure, may not threaten the lives of patients. Unfortunately, there are many fatal complications that are under reported. In this study, we report a case and perform a literature review to introduce malignant cerebral swelling, which is regarded as a devastating complication...

BACKGROUND: Intraosseous vascular anomalies (IOVA) are rare in the craniofacial skeleton and present a diagnostic and therapeutic challenge. This study aims to describe the clinical management based on a large case series. METHODS: A retrospective chart review was performed and 9 IOVA were identified over a 15-year period. Data on demographics, diagnostic features, clinical management, and outcomes were reviewed. RESULTS: Five frontal bone IOVA and 4 orbital IOVA were identified...

OBJECTIVE: This study aimed to explore relevant factors of hemorrhagic contusions following decompressive craniotomy (DC) in traumatic brain injury (TBI), and create an artificial neural network (ANN) prediction model of the risk factors of hemorrhagic contusions. METHODS: This study analyzed 425 patients with TBI who underwent DC in the Neurosurgery Department of Shaoxing People's Hospital between 2009 and 2014.

BACKGROUND: Merkel cell carcinoma (MCC) is a rare neuroendocrine skin tumor, which may be related to sun exposure. It can metastasize to lungs, liver and bone, leading to severe morbidity and mortality. Vertebral metastases from MCC are rare. The authors report the tenth case in the literature, a 59-year-old patient with MCC, which was primarily localized in the scalp, and later provoked distant metastasis to the thoracic spinal column. CASE DESCRIPTION: A 59-year-old woman was admitted at our Unit of Neurosurgery with a 4-month history of progressive and severe dorsal back pain, without neurological signs...

BACKGROUND: Poor outcomes of surgical treatment for complex cerebral aneurysms due to the development of cerebral ischemia were the cause to use cerebral revascularization surgery for this pathology. OBJECTIVE: the study objective was to master a high-flow extracranial-intracranial (EC-IC) artery bypass technique and evaluate its application in surgical treatment of complex and giant cerebral aneurysms as well as complex lesions of the brachiocephalic arteries. MATERIAL AND METHODS: Fifty two patients underwent high-flow IC-EC bypass surgery; of these, 34 patients had complex cerebral aneurysms, and 18 patients had complex stenotic occlusive lesions of the brachiocephalic arteries...

OBJECTIVE During the last 3 decades, robotic technology has rapidly spread across several surgical fields due to the continuous evolution of its versatility, stability, dexterity, and haptic properties. Neurosurgery pioneered the development of robotics, with the aim of improving the quality of several procedures requiring a high degree of accuracy and safety. Moreover, robot-guided approaches are of special interest in pediatric patients, who often have altered anatomy and challenging relationships between the diseased and eloquent structures...

BACKGROUND: Bone wax is a hemostatic agent well used by neurosurgeons to prevent bleeding from bone. However, several complications involving bone wax have been reported, such as ptosis, infection, paraplegia, osteohypertrophy, edema, pain, granuloma formation, allergic reaction, and thrombosis. CASE DESCRIPTION: A 47-year-old female patient presented to our neurosurgery department complaining of headache and vomiting. Subarachnoid hemorrhage from a ruptured aneurysm was detected on computed tomography (CT), and we performed emergent clipping of the ruptured aneurysm...

Surgical excision of meningioma is often complicated by significant blood loss requiring blood transfusion with its attendant risks. Although tranexamic acid is used to reduce perioperative blood loss, its blood conservation effect is uncertain in neurosurgery. Sixty adults undergoing elective craniotomy for meningioma excision were randomized to receive either tranexamic acid or placebo, initiated prior to skin incision. Patients in the tranexamic acid group received intravenous bolus of 20mg/kg over 20min followed by an infusion of 1mg/kg/h till the conclusion of surgery...

OBJECTIVE The authors investigated whether the presence of intradiscal vacuum phenomenon (IVP) results in greater correction of disc height and restoration of segmental lordosis (SL). METHODS A retrospective chart review was performed on every patient at the University of South Florida's Department of Neurosurgery treated with lateral lumbar interbody fusion between 2011 and 2015. From these charts, preoperative plain radiographs and CT images were reviewed for the presence of IVP. Preoperative and postoperative posterior disc height (PDH), anterior disc height (ADH), and SL were measured at disc levels with IVP and compared with those at disc levels without IVP using the t-test...

BACKGROUND: Not less than 50% of all ischaemic strokes appear to occur resulting from pathology of extracranial arteries. Occlusions and stenoses are more commonly encountered in carotid arteries, with the incidence of occlusion of the internal carotid artery (ICA) ranging from 5 to 10% within the structure of all lesions of brachiocephalic arteries (BCA). AIM: The study was aimed at assessing the results of a surgical procedure of extra-intracranial microanastomosis (EICMA) performed in patients presenting with occlusive and stenotic lesions of BCA at the Neurosurgical Department...

Aim To analyze the relationship between timing of surgery and outcome in patients with cauda equina syndrome caused by lumbar disc herniation. Methods A retrospective, non-randomized clinical study included 25 consecutive patients with cauda equina syndrome (CES) caused by lumbar disc herniation. All patients were operated within 24 hours after hospitalization at the Department of Neurosurgery, Cantonal Hospital Zenica, Bosnia and Herzegovina, between January 2000 and December 2010. All patients were evaluated before surgery on the basis of complete history, neurological examination and neuroimaging evaluations using CT (computed tomography)and MRI (magnetic resonance imaging)...

OBJECTIVE Contemporary theories of the pathophysiology of movement disorders emphasize abnormal oscillatory activity in basal ganglia-thalamocortical loops, but these have been studied in humans mainly using depth recordings. Recording from the surface of the cortex using electrocorticography (ECoG) provides a much higher amplitude signal than depth recordings, is less susceptible to deep brain stimulation (DBS) artifacts, and yields a surrogate measure of population spiking via "broadband gamma" (50-200 Hz) activity...
