RESUMEN

Meningiomas are benign, slow-growing tumors originating from arachnoid gap cells. They constitute 15%-20% of all intracranial tumors in adults and 04%-4% in the pediatric age group. Meningiomas in the posterior fossa in the pediatric period do not initially come to mind. In the case presented here, there was a cystic meningioma showing heterogenous contrast and obstructive hydrocephaly was observed associated with 4th ventricle pressure. the tumor was totally removed, then the ventriculo peritoneal shunt was applied.

RESUMEN

BACKGROUND: Magnetic resonance myelography (MRM) with three-dimensional (3D) T2-weighted (T2W) turbo spin echo (TSE) sampling perfection with application-optimized contrasts using different flip angle evolution (SPACE) may be a guide to the etiology of low back pain. PURPOSE: To research the efficiency of a 3D T2W TSE SPACE MRM sequence for visualization of anatomic details of spinal nerve root at the spinal canal and lateral recess levels in the patients with low back pain. MATERIAL AND METHODS: Lumbar spinal MRM 3D T2W TSE SPACE was performed in a total of 70 patients (median age 46 years). Patients were imaged while lying in a supine position with straightened legs. According to the degree of facet arthropathy findings, patients were divided into four separate subgroups in our retrospective cross-sectional study. Spinal nerve root angle was measured within the spinal canal and at lateral recess level, and facet joint angle and lumbar lordosis measurements were measured by two radiologists, independently. RESULTS: Lumbar level was strongly negatively correlated with facet joint angle (r = -0.95) as well as nerve root angle within the spinal canal (NRASC) (r = -0.857) and at the lateral recess level (NRALR) (r = -0.947). Intracanal decline of the spinal root angle caused by spinal stenosis findings was also observed (P < 0.05). For the measurements of NRASC and NRALR, inter-observer correlation was 0.85 and 0.82 for the spinal canal and at lateral recess level, respectively. CONCLUSION: 3D T2W SPACE in NRASC and NRALR provided high resolution images for evaluation. Therefore, this method may be a qualitative guide for the clinician and the surgeon in terms of root anatomy before any intervention.

RESUMEN

PURPOSE: Spinal Cord Society (SCS) and Spine Trauma Study Group (STSG) established a panel tasked with reviewing management and prognosis of acute traumatic cervical central cord syndrome (ATCCS) and recommend a consensus statement for its management. METHODS: A systematic review was performed according to the PRISMA 2009 guidelines. Delphi method was used to identify key research questions and achieve consensus. PubMed, Scopus and Google Scholar were searched for corresponding keywords. The initial search retrieved 770 articles of which 37 articles dealing with management, timing of surgery, complications or prognosis of ATCCS were identified. The literature review and draft position statements were compiled and circulated to panel members. The draft was modified incorporating relevant suggestions to reach consensus. RESULTS: Out of 37 studies, 15 were regarding management strategy, ten regarding timing of surgery and 12 regarding prognosis of ATCCS. CONCLUSION: There is reasonable evidence that patients with ATCCS secondary to vertebral fracture, dislocation, traumatic disc herniation or instability have better outcomes with early surgery (< 24 h). In patients of ATCCS secondary to extension injury in stenotic cervical canal without fracture/fracture dislocation/traumatic disc herniation/instability, there is requirement of high-quality prospective randomized controlled trials to resolve controversy regarding early surgery versus conservative management and delayed surgery if recovery plateaus or if there is a neurological deterioration. Until such time decision on surgery and its timing should be left to the judgment of physician, deliberating on pros and cons relevant to the particular patient and involving the well-informed patient and relatives in decision making.

RESUMEN

OBJECTIVEEnhanced recovery after surgery (ERAS) is a multimodal approach that aims to improve perioperative surgical outcomes. The aim of this study was to evaluate the benefits of ERAS in terms of cost-effectiveness and postoperative outcomes in single-level lumbar microdiscectomy.METHODSThis study was a single-center retrospective comparing costs and outcomes before and after implementation of the ERAS pathway. Data were collected from the electronic medical records of patients who had undergone single-level lumbar microdiscectomy during 2 time periods-during the 2 years preceding implementation of the ERAS pathway (pre-ERAS group) and after implementation of the ERAS pathway (ERAS group). Each group consisted of 60 patients with an American Society of Anesthesiologists (ASA) Physical Status Classification of class 1. Patients were excluded if their physical status was classified as ASA class II-V or if they were younger than 18 years or older than 65.Groups were compared in terms of age, sex, body mass index (BMI), perioperative hemodynamics, operation time, intraoperative blood loss, intraoperative fluid administration, intraoperative opioid administration, time to first oral intake, time to first mobilization, postoperative nausea and vomiting (PONV), difference between preoperative and postoperative visual analog scale (VAS) scores, postoperative analgesic requirements, length of hospital stay, and cost of anesthesia.RESULTSThe ERAS and pre-ERAS groups were comparable with respect to age, sex, and BMI. Operation time, intraoperative blood loss, intraoperative opioid administration, and intraoperative fluid administration were all less in the ERAS group. First oral intake and first mobilization were earlier in the ERAS group. The incidence of PONV was less in the ERAS group. Postoperative analgesic requirements and postoperative VAS scores were significantly less in the ERAS group. The length of hospital stay was found to be shorter in the ERAS group. The ERAS approach was found to be cost-effective.CONCLUSIONSERAS had clinical and economic benefits and is associated with improved outcomes in lumbar microdiscectomy.

RESUMEN

OBJECTIVE: Transoral odontoidectomy and ventral C1-2 stabilization are important surgical procedures, performed to decompress ventral spinal cord, and to stabilize craniovertebral junction. These procedures require knowledge regarding surgical anatomy of neurovascular structures ventral to the C1-2 complex. The aim of this study is to evaluate the relationships between neurovascular structures and bony landmarks in ventral atlantoaxial complex. MATERIALS AND METHODS: This study was performed on six formaldehyde fixed cadaveric head and neck specimens. Relevant anatomical parameters, including distances from the midsagittal line to internal carotid arteries (ICA), vertebral arteries (VA), and hypoglossal nerves (HN), were measured using electronic calipers. RESULTS: The mean distance between ICA and midsagittal line was observed as 26.13 mm at the level of axis and 24.67 mm at the level of the atlas. The mean distance between VA and midsagittal line was observed as 15.38 mm at the level of axis and 26.54 mm at the level of the atlas. The mean distance between HN and midsagittal line was observed as 33.27 and 33.58 mm at the level of the atlas and axis, respectively. CONCLUSION: This study confirmed that ICA and HN proceeded ventrally or laterally along the lateral aspect of the C1 lateral mass; therefore, the area located ventrally along the medial components of the C1 lateral mass was the safe zone for anterior surgical approach.

RESUMEN

INTRODUCTION: Lumbar foraminal inner zone herniations are challenging cases, for which there are variety of approaches. However, there is no information about the distance between these herniations and the edges of the respective lamina. The aim of this study was to measure the distance between the inferomedial aspect of lumbar pedicles and laminar edges. MATERIALS AND METHODS: The lumbar CT images of 30 cases were reviewed. The distances between the edges of the lamina and the inferomedial aspects of the respective pedicles were measured. The study was performed on L3, L4, and L5 lumbar vertebrae on both sides. RESULTS: The mean distance between the upper edge of the lamina and the inferomedial aspect of the respective pedicle was found to be 10.8 ± 3.5, 11.6 ± 2.4, and 14.1 ± 2.3 mm on the left side, and 11.1 ± 4.4, 12.0 ± 2.5, and 13.8 ± 3.2 mm on the right side of L3, L4, and L5 vertebrae. The mean distance between the inferior edge of the lamina and the inferomedial aspect of the respective pedicle was found to be 23.8 ± 4.2, 19.3 ± 3.5, and 11.6 ± 2.9 mm, on the left side, and 23.9 ± 3.2, 19.1 ± 3.7, and 12.4 ± 2.8 mm on the right side of L3, L4, and L5 vertebrae. There was no statistically significant difference between values of the left and right sides (p > 0.05). CONCLUSION: This study revealed that distance between the inferomedial aspect of lumbar pedicles and the superior edge of the same lamina was shorter than the distance between the inferomedial aspect of lumbar pedicles and the inferior edge of the same lamina at L3 and L4 level. It was concluded that this shorter distance could be taken into consideration during surgery on inner zone 1 foraminal herniations.

RESUMEN

OBJECTIVE: To review the diagnoses and surgical approach characteristics of giant spinal schwannomas (GSS) patients. METHODS: We reviewed the preoperative and postoperative radiological and clinical data, and the surgical aspects of 18 GSS patients who underwent surgery in the Department of Neurosurgery, Umraniye Teaching Hospital and Research State Hospital, Istanbul, Turkey between January 2008 and December 2013. RESULTS: There were 15 (83.3%) female and 3 (16.6%) male patients. The age range was 16-70 years (average: 45.8). Average symptom duration was 1.5 months (range: 1-48). There was local pain in 15 cases, and radicular pain in 6 cases. The GSSs were most frequently located in the lumbosacral area (11 cases, 61.1%). An extraforaminal surgical approach was employed in 7 cases, a posterior approach was employed in 6 cases, a combined anterior transabdominal and posterior approach was employed in 2 cases, a combined posterior and extraforaminal approach was employed in 2 cases, and a retroperitoneal approach was applied in one case. The tumors were completely excised in all cases. The mean follow-up period was 38.5 months (range: 20-68). CONCLUSION: Giant spinal schwannomas exhibit unique diagnostic and surgical factors. The selection of an appropriate approach significantly influences the success of the treatment.

RESUMEN

The aim of this article is to introduce the 19th century neurosurgery books to reveal their contributions to modern neurosurgery. Methods In this study, 29 books were accessed, and reviewed, and the resources from the late 18th century and early 20th century were included. However, neurology or general surgery books that included neurosurgical subjects or chapter were excluded unless there were revolutionary ideas in their relevant chapters. The books of this period observed to have some common differences from the books that were written in the previous century. Parallel to the concept of cerebral localization, which started to develop in this period, neurosurgery evolved from skull surgery to brain surgery. Due to the advancements in patient care, anesthesia and sterile techniques, surgical medical branches showed rapid development in the 1800s. During this period, cerebral localization concept changed the comprehension and approach in neurosurgery and opened the gate of a new era in the field of neurological surgery unlike other branches and helped to establish modern neurosurgery. 19th century surgeons became able to operate on more complex cases with more advanced techniques. Knowledge of published pioneer papers and books help understanding of emergence of neurological surgery as a separate discipline.

RESUMEN

BACKGROUND: The estimation of survival is extremely important for metastatic disease in the spine. The aim of this study was to determine the factors affecting the outcome of patients with spinal metastasis, primarily the character of neurologic deficit and the histopathology of the tumor. METHOD: A retrospective examination was made of 158 patients with spinal metastasis who were followed up in our clinic between 2010 and 2020 and underwent surgical intervention. The patients were examined in respect of demographic characteristics, the primary tumor, comorbidities, preoperative-postoperative visual aAnalog scale scores, preoperative-postoperative neurologic examinations and neurologic deficit if present and ambulation status, postoperative survival duration, tumor localization, characteristics of the surgeries, complications, the Karnofsky Performance Scale, revised Tokuhashi, and Tomita scores. RESULTS: Spinal metastasis was seen more frequently in males (72.8% male, 27.8% female). Male gender, multiple level involvement, intradural localization, and Karnofsky Performance Scale <70 were seen to cause a shorter survival time. Patients with a primary focus of hematologic malignancy, breast cancer, and lymphoma had a longer survival. The revised Tokuhashi and Tomita scores were observed to be successful in the prediction of survival. A decrease in postoperative visual analog scale score had a positive effect on functional survival. The absence of preoperative neurological deficit and the patient's ability for preoperative and postoperative ambulation affected survival positively. The overall survival period decreased in patients who were mobilized in the early postoperative period but became nonmobile in the late period, and in those who were nonmobile in both the early and late postoperative periods. CONCLUSIONS: The neurologic and ambulatory status, the Tomita and Tokuhashi scores, intradural localization, and gender are the factors with a significant effect on prognosis.

RESUMEN

AIM: To define a new approach for primary vertebral tumors by discussing them in the light of 2020 World Health Organization (WHO) classification of bone tumors. MATERIAL AND METHODS: In this study, we have discussed primary vertebral tumors in light of the 2020 Updated WHO Classification of Soft Tissue and Bone Tumors. RESULTS: Chondroblastoma and chondromyxoid fibroma has been classified in the benign category, while synovial chondromatosis has been moved from the benign category to the intermediate category. In the updated classification, grade I chondrosarcoma has been classified in the malignant category with grade II?III chondrosarcomas. Minor amendments have been made for osteosarcoma subtypes. Neoplasms of undetermined origin, such as aneurysmal cysts, simple bone cysts, fibrosis dysplasia, and osteofibrous dysplasia, have been classified as neoplastic lesions. Chordomas have been classified into ?not otherwise stated,? poorly differentiated chordomas, and dedifferentiated chordomas. Ewing?s sarcomas have been classified in a separate section for undifferentiated, small, round cell sarcomas of the bone and soft tissue. In this section, three distinct subsets different from Ewing?s sarcoma have been discussed. CIC-rearranged sarcoma, BCOR-rearranged sarcoma, and round cell sarcomas with EWSR1 gene fusion with non-ETS family members. CONCLUSION: In this study, we have reviewed the new classifications and discussed their effect on decision making in spinal oncologic surgery.

RESUMEN

AIM: To retrospectively evaluate the relationships between morphometric measurements in craniovertebral junction, and the possible genetic basis of the disease in Chiari 1 malformation patients undergoing surgical treatment. MATERIAL AND METHODS: We included patients who underwent surgical treatment for Chiari 1 malformation with unknown etiology between 2013-2018 in the Neuosurgery Clinic of Eskisehir Osmangazi University. Morphometric and volumetric measurements of the posterior fossa from cranial and cervical radiological imagings of patients with Chiari 1 malformation were performed by a single experienced observer. The results were independently reviewed by two experienced observers who supervised the process and verified the calculations. RESULTS: It was observed that basal angle was greater in the group of patients with Chiari 1 malformation (125.29° ± 9.522° Vs. 112.33° ± 9.09°), and a significant difference was observed (p=0.000). In patient group, it was also found that the basion-dens distance (3.51 mm ± 1.695mm Vs. 5.27 ± 1.695 mm) (p=0.000), and cerebellar hemispher height were shorter (58.47 ± 5.143 mm Vs. 52.05 ± 5,008 mm) (p=0.000). Tentorium angle was greater in the patient group (97.95° ± 11.321° vs. 87.79° ± 9.891°) (p=0.034). In patient group, dens height was found to be longer (13.9 ± 2.46 mm vs. 14.79 ± 1.631mm) (p=0.041). Sella volume was found to be smaller (41.4 mm3 Vs. 53.3 mm3) in the patient group compared to the control group (p=0.034), and foramen magnum plane was larger (64.6° vs. 31.1°) (p=0.000). CONCLUSION: It is concluded that many parameters including BA, FMP, BDD, CHH, TA, DH, and cellar volume are abnormal, suggesting the need for focussing to the hormonal metabolism - related synchondral changes.

RESUMEN

BACKGROUND: Spinal meningiomas are benign and slow-growing intradural tumors. Surgery is the choice of treatment. In this retrospective study, results of minimally invasive Simpson grade 2 resection and its impact on recurrence in 44 spinal meningiomas are reviewed. METHODS: Clinical data of 44 cases who underwent surgery for spinal meningiomas between 2010 and 2020 have been reviewed retrospectively. Demographics, preoperative and postoperative clinical states, pathologic type, location of the meningioma relative to the spinal cord, resection amount of the tumor according to Simpson's grading scale, postoperative complications, recurrence rate, and correlation between preoperative and intraoperative data and recurrence were analyzed. RESULTS: The tumor was located in the thoracic spine in 31 cases, in the cervical spine in 12 cases, and in the lumbar spine in one case. Dural attachment of tumor was ventral to the spinal cord in 15 cases, lateral to the spinal cord in 15 cases, and posterior to the spinal cord in 14 cases. All cases underwent microsurgical Simpson grade 2 resection. Two cases were recurrent and reoperated. Recurrences were observed in cases younger than 18 years old, in cervical spines and in cases with long dural tails. CONCLUSIONS: Simpson grade 2 resection is safe and effective in spinal meningiomas. Patients younger than 18 year old, and those with cervical location and long dural tail may be under risk of recurrence after Simpson grade 2 resection.

RESUMEN

Background: The treatment of Chiari malformations generally consists of posterior fossa decompression. C1 laminectomy is required in selected cases. However, cases of iatrogenic anterior arch fractures at C1 without high-energy trauma have been reported. Developing theoretical models of atlas C1 bones that have undergone a laminectomy can help researchers identify the regions where fractures may occur as a result of sudden loads. Methods: In this study, we created a detailed three-dimensional solid finite element model of the human atlas bone (C1) using geometric data. The loadings of the laminectomy dimension were evaluated on the basis of three groups. Group I comprised atlas bones that had not undergone a laminectomy. For Group II, the lateral border of the laminectomy was determined as the projection of the lateral mass medial border on the lamina. For Group III, the bilateral sulcus arteriosus was determined as the border for the lateral border of the laminectomy. The analysis results, which are in good agreement with those of previous reports, showed high concentrations of localized stress in the anterior and posterior arches of the atlas bone. Results: The analysis results showed that the stress increased in the laminectomy models. The maximum stress observed was consistent with the clinical observations of fracture sites in previous studies. Conclusion: In the treatment of patients with Chiari malformations, C1 laminectomy is often required. The width of this laminectomy can lead to iatrogenic anterior arch fractures. This is the first study to evaluate C1 laminectomy width using finite element modeling.

RESUMEN

Background The treatment of spinal schwannomas, which is the most common nerve sheath tumor, is total microsurgical resection. The localization, size and relationship with the surrounding structures of these tumors are crucial in terms of preoperative planning. A new classification method is presented in this study for the surgical planning of spinal schwannoma. Methods All patients who underwent surgery for spinal schwannoma between 2008 and 2021 were reviewed retrospectively, along with radiological images, clinical presentation, surgical approach, and postoperative neurological status. Results A total of 114 patients, 57 male, and 57 females were included in the study. Tumor localizations were cervical in 24 patients, cervicothoracic in one patient, thoracic in 15 patients, thoracolumbar in eight patients, lumbar in 56 patients, lumbosacral in two patients, and sacral in eight patients. All tumors were divided into seven types according to the classification method. Type 1 and Type 2 groups were operated on with a posterior midline approach only, Type 3 tumors were operated on with a posterior midline approach and extraforaminal approach, and Type 4 tumors were operated on with only an extraforaminal approach. While the extraforaminal approach was sufficient in type 5 patients, partial facetectomy was required in 2 patients. Combined surgery including hemilaminectomy and extraforaminal approach was performed in the type 6 group. A posterior midline approach with partial sacrectomy/corpectomy was performed in Type 7 group. Conclusion Effective treatment of spinal schwannoma depends on preoperative planning, which includes correctly classifying tumors. In this study, we present a categorization scheme that covers bone erosion and tumor volume for all spinal localizations.

RESUMEN

AIM: To propose a treatment algorithm, and to assess spinal instability in patients diagnosed with spinal lymphoma. MATERIAL AND METHODS: Demographics, symptoms, tumor level and location, and presence of spinal instability were reviewed in 22 patients with spinal lymphomas. Each patient's neurological state was reviewed using the American Spinal Injury Association and modified McCormick scale scores, and spinal instability was assessed using the Spinal Instability Neoplastic Score (SINS). RESULTS: Initially, percutaneous biopsy was performed in 16 patients, and open biopsy was performed in 6 patients. Eight of the patients who underwent percutaneous biopsy were followed up with hematological examination alone, as they had no additional complaints. The SINS was used to evaluate the presence of spinal instability, and the type of surgery to be performed was decided accordingly. In the second surgery, decompression and stabilization were performed in 5 of the remaining 8 patients, and only decompression was performed in 3 of them. Neurological improvement was observed in 6 of 7 patients with acute neurological deficit. CONCLUSION: Percutaneous biopsy for tissue diagnosis is the first step in the management of spinal lymphomas. Patients without neurological deficit should be referred for hematological examination. Those with acute neurological deficit require emergency surgery, and those with chronic symptoms must undergo operation for decompression and/or stabilization. This study confirmed the safety of the SINS in the evaluation of spinal instability in spinal lymphoma cases.

RESUMEN

OBJECTIVE: The aim of this study was to report the results of percutaneous vertebroplasty in managing symptomatic osteolytic cervical spine tumors. METHODS: This study comprised a retrospective examination of patients who received percutaneous vertebroplasty between 2008 and 2020 for the treatment of tumor-induced symptomatic cervical vertebra involvement. The study summarized the demographics, vertebral levels, pain control rates, clinical results, and complications of percutaneous vertebroplasty using an anterolateral approach. RESULTS: The study sample consisted of 6 female and 2 male patients aged between 20 and 56 (mean=41.37) years. Tumors were located at C2 in 6 cases, at C3 in 1 case, and at C5 in another. The mean volume of poly (methyl methacrylate) injected was 1.5 mL (range: 1-2 mL). Biopsy results showed the presence of metastasis in 5 cases and plasmacytoma in 3. No postoperative complications or mortality were observed after the procedure. Preoperative mean 7.75 visual analog scale score decreased to 2.62. Pain control was reported to be 66.2%. CONCLUSION: Anterolateral cervical vertebroplasty seems to be a safe, effective, and helpful therapeutic alternative for the treatment of cervical spine tumors. It reduces the risk of infection compared to the transoral method. LEVEL OF EVIDENCE: Level IV, Therapeutic Study.

RESUMEN

OBJECTIVE: The decision to perform surgery in cases of spinal plasmacytoma (SP) is controversial. This study aimed to evaluate the reliability of the Spinal Instability Neoplastic Score (SINS) in evaluation of spinal instability in patients with SP. METHODS: Clinical and radiological characteristics of 10 patients with SP were retrospectively evaluated. Age, sex, preoperative symptoms, duration of symptoms, pain score, American Spinal Injury Association score, and SINS were analyzed. RESULTS: The 10 patients included 6 men and 4 women. Plasmacytoma was located in the sacrum in 1 patient, in the lumbar spine in 2 patients, in the thoracic spine in 6 patients, and in the cervical spine in 1 patient. Biopsy was performed in 2 patients, biopsy and vertebroplasty were performed in 2 patients, and biopsy and acute decompression and stabilization surgery were performed in 6 patients. SINS was <7 in 1 patient, 7-12 in 5 patients, and >12 in 4 patients. Two patients with a low SINS (<13) underwent only biopsy, and 2 patients underwent biopsy and vertebroplasty. Decompression and stabilization surgery was performed in 2 patients with SINS 7-12 and 4 patients with SINS >12. CONCLUSIONS: Decision making regarding augmentation, decompression, and stabilization in patients with SP is controversial. SINS may play a role during the decision-making process. Augmentation can be performed in patients with painful SPs with osteolytic changes with or without fracture (SINS <13). Decompression and stabilization surgery is the first-choice treatment in patients with SINS >12.

RESUMEN

INTRODUCTION: The surgical treatment of craniovertebral junction (CVJ) lesions remains a difficult process requiring advanced experience. The aim of this study was to present our experience and the clinical results of a posterior and posterolateral approach used for CVJ lesions in our clinic, and to discuss these in light of current literature. METHODS: Clinical, radiologic, and surgical aspects of 30 patients with CVJ tumors were retrospectively evaluated. Age, sex, symptoms, tumor localizations, pre- and postoperative neurologic examinations, performed surgical techniques, postoperative complications, and tumor pathologies were analyzed. The modified McCormick classification was used in the evaluation of the neurologic examination. RESULTS: There were 30 patients (12 men, 18 women; mean age: 41.8 years). Hemilaminectomy was performed in 14 cases, and total laminectomy or laminoplasty in 16 cases; additional suboccipital craniectomy was performed in 6. Postoperative mortality was observed in 1 (3.3%) patient in the early postoperative period following tetraparesis, motor deficit in 2 (6.6%), cerebrospinal fluid leakage in 2 (6.6%), and wound site infection in 1 (3.3%). A tumor rest was detected in 2 patients (6.6%). CONCLUSIONS: A posterior or a posterolateral approach is a safe surgical technique that can provide total tumor resection for CVJ region lesions, including posterior, posterolateral, lateral, and anterolaterally located tumors. Isolated anterior and anterolateral tumors with small lateral extension may require a far lateral or extreme lateral approach combined with other cranial base techniques.
