There are no uniform guidelines for it. Given this, we planned to study the comparative outcome between EVD drainage with intermittent clamping versus EDV followed by Ommaya reservoir.\u0000 Material and Methods The present retrograde observational study was conducted from July 2018 to March 2021 in the department of neurosurgery with 67 patients who developed hydrocephalus following SAH after aneurysm rupture. We divided the patients into two groups. Group 1 had only EVD placed for CSF drainage with intermittent clamping before the placement of the ventriculoperitoneal (VP) shunt, and, in group 2, an Ommaya reservoir was placed after EVD before the shunt.\u0000 Result There were 38 patients in group 1 and 29 in group 2. They were age-matched, with a mild male predominance in group 1. Shunt dependency was significantly reduced in group 2 patients (p = 0.011), along with reduced length of stay in ICU (p = 0,001) and length of stay in Hospital (p = 0.019). We found improved Glasgow outcome score in group 2 patients (p = 0.006) together with reduced incidence of infarct (p = 0.0095).\u0000 Conclusion We may infer from the present study that continuous drainage through EVD, initially, in hydrocephalus induced by SAH following aneurysm rupture, increases cerebral perfusion pressure (CPP) and decreases intracranial pressure (ICP) leading to decreased infarct rate and intermittent drainage through Ommaya following EVD reservoir, decreases shunt dependency, reduces ICU and hospital stay, with improved Glasgow outcome score on follow-up, but these findings need to be validated in a prospective randomized control trial.","PeriodicalId":42205,"journal":{"name":"Brazilian Neurosurgery-Arquivos Brasileiros de Neurocirurgia","volume":"500 1","pages":""},"PeriodicalIF":0.1,"publicationDate":"2022-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76842572","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Endoscopic third ventriculostomy (ETV) is indicated for the treatment of obstructive hydrocephalus, with a reported efficacy between 50% and 76%. Reduced efficacy of the procedure has been demonstrated in communicating hydrocephalus due to multifactorial pathogenesis, and, in patients with myelomeningocele, its efficacy ranges from 15% to 20% at birth. The present study aims to compare the efficacy of ETV in the treatment of congenital obstructive hydrocephalus (COH) and acquired obstructive hydrocephalus (AOH) in the pediatric population.\u0000 Methods A retrospective study of 169 endoscopic surgeries performed by the senior author in two institutions, one public (Hospital João XXIII, Belo Horizonte, Minas Gerais) and another private (Hospital Felício Rocho, Belo Horizonte, Minas Gerais), in the period from 2003 a 2020. From the selection of 169 patients, only 77 cases fit the age profile ≤12 years of the present study. Of these, 46 were male, and the age range ranged from 10 days to 12 years. The study included multiple etiologies, which were divided into 2 groups, 34 related to COH, and 43 to AOH.\u0000 Results Regarding the cases of COH, 22 were submitted to ETV as the main treatment, with 14 (63.63%) effective and 8 (36.36%) ineffective procedures.

Due to the significant frequency rate of traumatic cervical spinal cord injuries (TCSCI), the possible association between imaging findings and clinical outcome is not yet clear. In this study, we quantified maximum spinal cord compression and maximum cord swelling following TCSCI and determined the relevance of imaging findings to clinical outcome in patients.\u0000 Materials and Methods This retrospective cohort comprises 20 patients with TCSCIs (C3-C7), classified as complete, incomplete, and no SCI, who were treated at the Poursina Hospital, Iran, from 2018 to 2020, and underwent spinal surgery. Patients with penetrating injuries and multiple trauma were excluded. Imaging findings revealing spinal cord compression, swelling, and canal stenosis, based on the American Spinal Injury Association (ASIA) Impairment Scale (AIS) grades of patients from hospital admission (up to 48 hours after injury) and improvement of postoperative neurological symptoms (6–12 months) were evaluated.\u0000 Results Cord compression (p = 0.05) and cord swelling (p = 0.02) were significantly related to predictive neurological outcomes in all cases.

The present report addresses an uncommon complication in the abdominal cavity, in which the catheter caused extrinsic compression of the gastric wall.\u0000 Case report A 30-year-old man presented a decreased level of consciousness, associated with severe headache and vomiting. He had a history of congenital neurotoxoplasmosis and VP shunt insertion at 7 years of age. Imaging exams demonstrated the formation of an encapsulated retrogastric pseudocyst and extrinsic compression of the gastric wall by a VP shunt catheter. Through videolaparoscopy, decompression of the gastric wall and removal of the pseudocyst were performed, with the reestablishment of the drainage of cerebrospinal fluid. An analysis of the distal fragment of the removed catheter revealed obstruction by fibrotic material. The patient was discharged with a reestablished baseline after four days of hospitalization.\u0000 Comments The literature shows that ∼ 47% of the complications presented by patients are related to the distal end of the catheter, and 8.2% of these come from migration to the abdominal cavity. However, there is an extreme paucity of studies that demonstrate extrinsic compression of the gastric wall by a VP shunt catheter. Therefore, we suggest that further studies on complications involving the VP shunt be performed to improve diagnostic and therapeutic results, in addition to complementing the literature on this complication.","PeriodicalId":42205,"journal":{"name":"Brazilian Neurosurgery-Arquivos Brasileiros de Neurocirurgia","volume":"18 1","pages":""},"PeriodicalIF":0.1,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78241796","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The condition evolved with walking difficulty and neck pain that was exacerbated by swallowing and mobilizing the neck. During her ocular melanoma follow-up, lesions suggestive of metastasis in the central nervous system were not evidenced until this moment. The physical examination did not show significant findings, and a cranial computed tomography scan was performed. The image showed a hyperdense lesion with postcontrast enhancement inside the vertebral canal, at the level of C1-C2. Spinal decompression and subtotal resection were performed.
