Analysis of prognostic factors and the role of epilepsy in neurosurgical patients with brain metastases.

Background: Brain metastases (BMs) represent the most frequent brain tumors in adults. The identification of key prognostic factors is essential for choosing the therapeutic strategy tailored to each patient. Epilepsy can precede several months of other clinical presentations of BMs.

Haemostatic technique in malignant gliomas.

Introduction: Haemostasis in brain surgery is mandatory to avoid postoperative re-bleeding and a poor outcome. Postoperative intra-cavity haemorrhage is a frequent complication, especially in surgery of malignant gliomas because of the fragility of pathological vessels.

Material And Methods: In this technical note, we describe our 'compression' technique used to achieve haemostasis in adult patients who underwent surgery for supratentorial malignant gliomas (GBM) at our Institute from January 2019 to January 2022.

Pre-operative hematological markers as predictive factors for overall survival and progression free survival in glioblastomas.

Introduction: Several hematological factors, such as neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), prognostic nutrition index (PNI) and albumin-to-globulin ratio (AGR), have been highlighted as systemic worse prognostic parameters for the outcome in gliomas. The aim of this study is to identify some pre-operative routinely blood tests as predictive parameters for the Overall Survival (OS) and Progression Free Survival (PFS) in glioblastoma (GBM).

Materials And Methods: From January 2013 to April 2019, 124 patients operated for glioblastoma were analyzed.

Laminectomy versus open-door laminoplasty for cervical spondylotic myelopathy: A clinical outcome analysis.

Background: Cervical spondylotic myelopathy (CSM) is one of the most common diseases in the geriatric population. Decompressive laminectomy or laminoplasty is the predominant surgical procedure of choice, but there remains debate as to which procedure is optimal for managing CSM.

Methods: Here, we retrospectively analyzed 64 patients with CSM undergoing laminectomy (39 patients) versus laminoplasty (25 patients).

Sixth Cranial Nerve Palsy and Craniocervical Junction Instability due to Metastatic Urothelial Bladder Carcinoma.

Metastases involving the clivus and craniocervical junction (CCJ) are extremely rare. Skull base involvement can result in cranial nerve palsies, while an extensive CCJ involvement can lead to spinal instability. We describe an unusual case of clival and CCJ metastases presenting with VI cranial nerve palsy and neck pain secondary to CCJ instability from metastatic bladder urothelial carcinoma.

Coil Extrusion into the Naso- and Oropharynx Ten Years after Internal Carotid Artery Pseudoaneurysm Embolization: A Case Report.

Coil migration and extrusion outside the cranial compartment after embolization of cerebral aneurysms represents a very rare complication of the endovascular procedures and few cases are reported in the literature. Instability of the vascular malformation wall and the resolution of the intramural hematoma, especially in pseudoaneurysm, might generate extravascular migration of the coils in the first months after embolization. However, to the best of our knowledge, an extrusion of coil 10 years after embolization has never been reported.

New or Blossoming Hemorrhagic Contusions After Decompressive Craniectomy in Traumatic Brain Injury: Analysis of Risk Factors.

The development or expansion of a cerebral hemorrhagic contusion after decompressive craniectomy (DC) for traumatic brain injury (TBI) occurs commonly and it can result in an unfavorable outcome. However, risk factors predicting contusion expansion after DC are still uncertain. The aim of this study was to identify the factors associated with the growth or expansion of hemorrhagic contusion after DC in TBI.

Risk factors for post-traumatic hydrocephalus following decompressive craniectomy.

Background: Post-traumatic hydrocephalus (PTH) is one of the main complications of decompressive craniectomy (DC) after traumatic brain injury (TBI). Then, the recognition of risk factors and subsequent prompt diagnosis and treatment of PTH can improve the outcome of these patients. The purpose of this study was to identify factors associated with the development of PTH requiring surgical treatment in patients undergoing DC for TBI.

Decompressive Craniectomy for Traumatic Brain Injury: The Role of Cranioplasty and Hydrocephalus on Outcome.

Objective: After severe traumatic brain injury (sTBI) associated with uncontrollable high intracranial pressure (ICP), today the main challenge for neurosurgeons remains to identify who may obtain benefit from decompressive craniectomy (DC) and which factors after DC influence the prognosis of these patients. The aim of this paper was to identify the pre- and postoperative determinants of outcome after DC.

Methods: This retrospective study included all patients undergoing DC for sTBI from 2003 to 2011.

Prognostic Factors in Glioblastoma: Is There a Role for Epilepsy?

The prognostic relevance of epilepsy at glioblastoma (GBMs) onset is still under debate. In this study, we analyzed the value of epilepsy and other prognostic factors on GBMs survival. We retrospectively analyzed the clinical, radiological, surgical and histological data in 139 GBMs.

Endoscopic Endonasal Odontoidectomy with Anterior C1 Arch Preservation in Rheumatoid Arthritis: Long-Term Follow-Up and Further Technical Improvement by Anterior Endoscopic C1-C2 Screw Fixation and Fusion.

Objective: To examine the long-term outcomes (minimum of 4.5 years) of endoscopic endonasal odontoidectomy (EEO) with preservation of anterior C1 ring to treat irreducible ventral bulbo-medullary compressions in rheumatoid arthritis (RA) and to illustrate a novel technique of anterior pure endoscopic craniovertebral junction (CVJ) reconstruction and fusion. In fact, long-term clinical studies are still lacking to elucidate the effective role of EEO and whether it can obviate the need for posterior fixation.

Supraorbital subfrontal trans-laminar endoscope-assisted approach for tumors of the posterior third ventricle.

Background: Different surgical approaches have been developed for dealing with third ventricle lesions, all aimed at obtaining a safe removal minimizing brain manipulation. The supraorbital subfrontal trans-lamina terminalis route, commonly employed only for the anterior third ventricle, could represent, in selected cases with endoscopic assistance, an alternative approach to posterior third ventricular lesions.

Methods: Seven patients underwent a supraorbital subfrontal trans-laminar endoscope-assisted approach to posterior third ventricle tumors (two craniopharyngiomas, one papillary tumor of the pineal region, one pineocytoma, two neurocytomas, one glioblastoma).

Endoscopic Transnasal Odontoidectomy With Anterior C1 Arch Preservation and Anterior Vertebral Column Reconstruction in Patients With Irreducible Bulbomedullary Compression by Complex Craniovertebral Junction Abnormalities: Operative Nuance.

Background: During the past decades, the transoral transpharyngeal approach has been advocated as the standard route for the removal of odontoid causing an irreducible symptomatic neural compression. However, it may be potentially associated with a significant built-in morbidity because of the splitting of the soft palate for an adequate working angle, tracheostomy, and incision of the oral mucosa, causing exposure to a higher risk of infection by oral flora.

Objective: To describe our experience with the minimally invasive pure endoscopic transnasal odontoidectomy in patients with bulbomedullary compression affected by complex anterior craniovertebral junction abnormalities.

Treatment of unstable thoracolumbar junction fractures: short-segment pedicle fixation with inclusion of the fracture level versus long-segment instrumentation.

Background: The surgical management of thoracolumbar burst fractures frequently involves posterior pedicle screw fixation. However, the application of short- or long-segment instrumentation is still controversial. The aim of this study was to compare the outcome of the short-segment fixation with inclusion of the fracture level (SSFIFL) versus the traditional long-segment fixation (LSF) for the treatment of unstable thoracolumbar junction fractures.

Posterior Titanium Screw Fixation without Debridement of Infected Tissue for the Treatment of Thoracolumbar Spontaneous Pyogenic Spondylodiscitis.

Study Design: Retrospective study.

Purpose: The aim of our study was to analyze the safety and effectiveness of posterior pedicle screw fixation for treatment of pyogenic spondylodiscitis (PSD) without formal debridement of the infected tissue.

Overview Of Literature: Posterior titanium screw fixation without formal debridement of the infected tissue and anterior column reconstruction for the treatment of PSD is still controversial.

Paradoxical Brain Herniation After Decompressive Craniectomy Provoked by Drainage of Subdural Hygroma.

Background: Paradoxical brain herniation (PBH) is a rare and potentially life-threatening complication of decompressive craniectomy (DC) and results from the combined effects of brain gravity, atmospheric pressure and intracranial hypotension causing herniation in the direction opposite to the site of the DC with subsequent brainstem compression. To date, the cases of PBH reported in literature are spontaneous or provoked by a lumbar puncture, a cerebrospinal fluid (CSF) shunt, or ventriculostomy.

Case Description: We present an uncommon case of PBH provoked by percutaneous drainage of a huge subdural hygroma (SH) ipsilateral to the decompressive craniectomy causing mass effect and neurologic deterioration.

Calvarial bone cavernous hemangioma with intradural invasion: An unusual aggressive course-Case report and literature review.

Introduction: Cavernous hemangioma of the skull is a rare pathological diagnosis, accounting for 0.2% of bone tumors and 7% of skull tumors. Usually calvarial bone cavernous hemangioma are associated with a benign clinical course and, despite their enlargement and subsequent erosion of the surrounding bone, the inner table of the skull remains intact and the lesion is completely extracranial.

Microsurgical endoscopy-assisted anterior corpus callosotomy for drug-resistant epilepsy in an adult unresponsive to vagus nerve stimulation.

Because most of the corpus callosotomy (CC) series available in literature were published before the advent of vagus nerve stimulation (VNS), the efficacy of CC in patients with inadequate response to VNS remains unclear, especially in adult patients. We present the case of a 21-year-old female with medically refractory drop attacks that began at the age of 8 years, which resulted in the patient being progressively unresponsive to vagus nerve stimulation implanted at the age of 14 years. Corpus callosotomy was recommended to reduce the number of drop attacks.

Combined supra-transorbital keyhole approach for treatment of delayed intraorbital encephalocele: A minimally invasive approach for an unusual complication of decompressive craniectomy.

Background: Intraorbital encephalocele is a rare entity characterized by the herniation of cerebral tissue inside the orbital cavity through a defect of the orbital roof. In patients who have experienced head trauma, intraorbital encephalocele is usually secondary to orbital roof fracture.

Case Description: We describe here a case of a patient who presented an intraorbital encephalocele 2 years after severe traumatic brain injury, treated by decompressive craniectomy and subsequent autologous cranioplasty, without any evidence of orbital roof fracture.

Surgical treatment of cervical spine trauma: Our experience and results.

Objective And Background: The objective of this study is to evaluate how the neurological outcome in patients operated for cervical spinal cord injury (SCI) is influenced by surgical timing, admission American Spinal Injury Association (ASIA) grading system, and age.

Materials And Methods: From January 2004 to December 2011, we operated 110 patients with cervical SCI. Fifty-seven of them (44 males and 13 females) with preoperative neurological deficit, were included in this study with a complete follow-up.

Neurological outcome in a series of 58 patients operated for traumatic thoracolumbar spinal cord injuries.

Background: Traumatic thoracolumbar spinal fractures represent approximately 65% of all traumatic spinal fractures and are frequently associated to permanent disability with significant social and economic impact. These injuries create severe physical limitations depending on neurological status, level of fracture, severity of injury, patient age and comorbidities. Predicting neurological improvement in patients with traumatic spinal cord injuries (SCIs) is very difficult because it is related to different preoperative prognostic factors.

Combined endoscopic transforaminal-transchoroidal approach for the treatment of third ventricle colloid cysts.

Colloid cysts are histologically benign lesions whose primary goal of treatment should be complete resection to avoid recurrence and sudden death. Open surgery is traditionally considered the standard approach, but, recently, the endoscopic technique has been recognized as a viable and safe alternative to microsurgery. The endoscopic approach to colloid cysts of the third ventricle is usually performed through the foramen of Monro.
