Abstract:

OBJECT Over the last decade, image guidance systems have been widely adopted in neurosurgery. Nonetheless, the evidence supporting the use of these systems in surgery remains limited. The aim of this study was to compare simultaneously the effectiveness and safety of various image guidance systems against that of standard surgery. METHODS In this preclinical, randomized study, 50 novice surgeons were allocated to one of the following groups: 1) no image guidance, 2) triplanar display, 3) always-on solid overlay, 4) always-on wire mesh overlay, and 5) on-demand inverse realism overlay. Each participant was asked to identify a basilar tip aneurysm in a validated model head. The primary outcomes were time to task completion (in seconds) and tool path length (in mm). The secondary outcomes were recognition of an unexpected finding (i.e., a surgical clip) and subjective depth perception using a Likert scale. RESULTS The time to task completion and tool path length were significantly lower when using any form of image guidance compared with no image guidance (p < 0.001 and p = 0.003, respectively). The tool path distance was also lower in groups using augmented reality compared with triplanar display (p = 0.010). Always-on solid overlay resulted in the greatest inattentional blindness (20% recognition of unexpected finding). Wire mesh and on-demand overlays mitigated, but did not negate, inattentional blindness and were comparable to triplanar display (40% recognition of unexpected finding in all groups). Wire mesh and inverse realism overlays also resulted in better subjective depth perception than always-on solid overlay (p = 0.031 and p = 0.008, respectively). CONCLUSIONS New augmented reality platforms may improve performance in less-experienced surgeons. However, all image display modalities, including existing triplanar displays, carry a risk of inattentional blindness.

Abstract:

Current resorbable membranes are generally from animal origin, like collagen, and are largely used in dentistry or orthopaedic for TGR (Tissue Guided Regeneration), in neurosurgery for Dura matter healing and others. Calcium alginates are generally used for wound dressing (external uses). The purpose of this study was to evaluate the osteogenic property of meshes realized with calcium alginate fibers. Membrane meshes were implanted in critical size defect of rabbit femoral epiphysis during 3 and 6 weeks. Micro CT and histological analysis demonstrated biocompatibility of calcium alginate meshes in bony area. Calcium alginate meshes have no osteogenic and osteoconductive properties, however calcium alginate meshes could be a good candidate for replacement of dacron balloon used in vertebroplasty.

Abstract:

Сraniotomy is an integral part of modern elective neurosurgery which involves cutting a free bone flap to provide access to pathological intracranial structures with its reimplantation at the end of surgery.Bone flap grafting in the trepanation window with various fixation methods in the end of elective neurosurgery in the absence of severe cerebral edema or cancer-induced bone destruction is a standard procedure that restores the skull shape, cerebrospinal fluid dynamics and cerebral perfusion.According to the literature, the incidence of aseptic inflammation with subsequent resorption of the bone flap after craniotomy in elective neurosurgery is not clearly defined.An analysis of medical publications in the PUBMED database showed few reports of bone flap resorption after elective craniotomy, and no reports were found after the search in the eLibrary database.Thus, the number of reports on the bone flap resorption after craniotomy in elective neurosurgery is limited, and the pathophysiology of this process remains unclear.However, the described complication of craniotomy can lead to the dislocation of a bone flap, the development of a local pain syndrome, a cosmetic defect, and disturbances in cerebrospinal fluid dynamics.The article describes an example of partial resorption of a bone flap after craniotomy for the removal of meningioma in the middle third of the superior sagittal sinus, which required a number of repeated neurosurgical interventions. The treatment was finished with the removal of a partially resorbed bone flap and implantation of an individual titanium mesh implant.

Abstract:

AbstractSchizophrenia is a chronic and disabling psychiatric disease that can be refractory to conventional treatment. The present study aims to gather information about the circuitry related to schizophrenia to describe possible surgical targets, and to establish whether psychosurgery can be a safe and effective treatment option for refractory schizophrenia. A systematic review of the literature was conducted and reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. An electronic search was performed in the Pubmed and BVSalud databases using medical subject headings (MeSH) combined with Boolean operators. Out of the 724 studies retrieved, 13 were included in the review. Regarding leucotomy without a stereotactic approach, we found side effects such as irritability, nervous excitement, cases of disinhibition, and compromised normal social control. In other stereotactic procedures, there was some improvement, mainly regarding aggressiveness and positive symptoms; an anterior capsulotomy had an efficacy rate of 74% according to the Clinical Global Impression (CGI) rating scales. The only deep brain stimulation (DBS) case report found in our study described a significant improvement in the positive and negative symptoms. The use of a stereotactic approach enables psychosurgery to be a safe and effective treatment option in cases of refractory schizophrenia, improving the quality of life and the symptoms. Cognitive and negative symptoms remain a challenge in the treatment of schizophrenia, revealing that more targets in the circuitry must be surgically explored. Furthermore, more clinical trials are needed to compare these many surgical techniques and targets, using a standard evaluation parameter. The results show that DBS has a promising future in the treatment of refractory schizophrenia.

Abstract:

Purpose: When scalp infection occurs after craniectomy and cranioplasty, it tends to be recurrent and fatal. The infection can spread to the underlying tissue when the skull is not present to act as a barrier, eventually leading to epidural abscesses and encephalitis. In such cases of widespread infection, reconstruction of scalp and skull defect after surgical debridement of infected tissue is a great challenge for plastic and neurosurgeons.Methods: Six patients with infection of forehead, scalp, and underlying dura were referred to our clinic for the control of repeated infection. Features and duration of infection, the presence of foreign bodies, bacterial culture tests, types of free flaps, and postoperative complications were investigated.Results: All cases were intracranial infections after neurosurgery and the duration of infection was 4.3±2.6 months. Foreign bodies (artificial bone, titanium mesh, plate, and screw) were present in three cases. Antibiotic-resistant bacteria were cultured in five cases (methicillin-resistant Staphylococcus aureus, methicillin-resistant coagulase-negative staphylococci, carbapenem-resistant Acinetobacter baumannii). For the control of infection, removal of foreign body and free tissue transfer was performed. The infection was controlled successfully during follow-up periods (59.3±42.0 months). Conclusion: Intracranial infections after neurosurgery on the skull can be fatal and lead to long-term sequelae. For the control of intracranial infection with antibiotic-resistant bacteria, well-vascularized free tissue transfer followed by foreign body removal is recommended. After infection control through free tissue transfer, secondary operations such as cranioplasty with titanium mesh or fat injection can be performed safely without recurrence of infection.

Abstract:

Calvarial bone defects are due to cranial bone removal at the end of the surgery (decompressive craniectomy), either because of bone involvement of the tumor or as a method to relieve intracranial pressure caused by important cerebral edema secondary to large tumors or traumas. With the progress of biomedical technology, new materials are available for use by surgeons. The titanium mesh implant is a plating platform with a matrix design and MRI compatibility that can be easily shaped, cut, and bent by the surgeon according to the bone defect. It is locked in place by several screws tapped into the bone. Although may different type of materials are currently available there is no consensus for the best method to be used. The aim of this study was to report our experience with titanium mesh implants for cranial repair and reconstruction of bone anatomy.Twenty four patients with decompressive craniectomies that required reconstruction of the calvarial bone defect for which a titanium mesh cranioplasty was used, operated in our Neurosurgery Department between January 2013 and April 2016 where included in this retrospective study. Of the 24 patients, only one had a localized infection complication for which the patient was re-operated and the implant removed with no other complications. No other neurological, infectious and functional complications were observed during or after surgery. All other patients had excellent anatomic and functional results with a positive feedback for the aesthetic aspects of the implant. The use of these bio-compatible materials is a viable, safe and reliable solution for the management of cranial bone defects offering the surgeon a large array of options for the benefit of the patient. It has a proven cost-effectiveness when compared to other customized prosthetics with the same outcomes. The MRI compatibility was proven very useful, especially for neoplasm patients who required frequent cranial imaging follow-ups, and reduced operating time was particularly beneficial to elderly patients.

Abstract:

abstract BACKGROUND AND IMPORTANCE: Subgaleal drains are commonly used in neurosurgery. Rare complications attributed to these drains have been described. We present a rare complication of hemodynamic collapse and multiple epidural hematomas attributed to intracranial hypotension induced by a subgaleal drain connected to suction during wound closure. CLINICAL PRESENTATION: A 3.5-year-old boy underwent an uneventful occipital lobectomy and titanium mesh cranioplasty for resection of a recurrent choroid plexus carcinoma. The child had undergone 2 uneventful previous resections and cranial irradiation. During skin closure, a subgaleal drain was connected to suction to keep the surgical bed dry. Immediately after completion of the subgaleal layer closure, there was an acute hemodynamic collapse, accompanied by bradycardia and a drop in the hematocrit. After successful resuscitation, the child underwent a brain computed tomography scan that showed a large bifrontal epidural hematoma and multiple additional small epidural hematomas. The large hematoma was surgically evacuated, and the child had an uneventful recovery. CONCLUSION: Acute negative intracranial hypotension may cause bradycardia, epidural hematomas, and hemodynamic collapse. Subgaleal drains should not be connected to suction systems, and care should be taken when these drains are connected to vacuum bulbs in high-risk cases such as after cranial irradiation, large resections, and mesh cranioplasties.

Abstract:

Pyogenic vertebral osteomyelitis (PVO) is still a rare pathology. However, its incidence is on the rise. This is due to an increasing population with predisposing factors. Also, the availability of more effective diagnostic tools has brought it increasingly to the surgeon’s attention. In this study the patients were treated in the Neurosurgery Division of the Department of Neurological Sciences and Psychiatry of the Sapienza University of Rome, between 2001 and 2009. They had thoracolumbar pyogenic spondylitis. This study was undertaken in order to identify the correct diagnostic and therapeutic treatment needed in such cases. From the cases studied here, it is evident that spinal infections can be extremely insidious and that diagnosis tends to be reached late. Surgery, along with the antibiotic treatment, allows for eradication of the causes of the pathology by the reclamation of the affected region. Surgery is also fundamental in helping to recover vital functions and in restoring as much as possible the correct curvature of the rachises. The use of an anterolateral approach is dictated by the necessity of obtaining 360° stability as well as by the need to clear away extensive infections, which are not always reachable using a posterior approach.
