RESUMO
BACKGROUND: Neuroendoscopic surgeries require specialized equipment, which may not be universally available or equitably distributed in most neurosurgical units of resource-limited healthcare systems. This review reports on the use of locally available resources to perform safe ventricular endoscopic surgeries in patients with hydrocephalus and cystic craniopharyngioma in a resource-limited healthcare system. METHODS: This study described the use of locally available resources to perform intraventricular endoscopic surgeries and retrospectively reviewed a 3-year outcome of these surgeries. A 24F, 2-way Foley catheter was used as an endoscopic working sheet. A transparent 9-mm nasotracheal tube served as a retractor and a peel-away sheath. An intravenous fluid administration set was used for irrigation. Finally, a metallic stylet of an external ventricular drain was used for third ventricular floor or cyst wall fenestration. RESULTS: There were 21 intraventricular endoscopic surgeries performed consisting of endoscopic third ventriculostomy (ETV), septostomy, cystostomy, and intraventricular biopsy. Four patients died, with 1 death directly related to intraoperative hemorrhage. Most (3/21) of the complications were postoperative cerebrospinal fluid leakage and partial wound dehiscence. Of the 17 surviving patients, the ETV success rate was 82.4% (14/17). Logistic regression analysis revealed that patient age, etiology, Endoscopic Third Ventriculostomy Success Score, and procedure performed were not predictive of ETV success or mortality. CONCLUSIONS: Patients accessing neurosurgical care in resource-limited healthcare systems can benefit from safe and successful intraventricular endoscopy. However, this may require the innovative use of locally available resources that can be adapted to local neurosurgical needs.
RESUMO
Background/Objectives: Spinal cord injury is a devastating condition and has been recognised so since antiquity with evolving pattern of presentation and outcome. This study aimed to review the clinical profile and determinants of early outcome in patients with traumatic spinal cord injury (TSCI) in Jos, Nigeria. Materials and Methods: This retrospective cohort study, reviewed the health records of all patients with TSCI that were managed, based on the neurosurgical unit protocol for the management of TSCI in our institution from 2011 to 2021. Relevant data were retrieved into a preformed pro forma, analysis was done for determinants of outcome using SPSS and presented in tables and figure. Results: A total of 296 patients, aged 20-39 years, with male to female ratio of 5.2:1 were studied. The median time from injury to presentation was 96 h, and the cervical spine was the most (139, 47.0%) affected region. Most of the patients (183, 61.8%) had complete injury (ASIA A) at presentation, the average, first week mean arterial blood pressure (MAP) of 89.98 ± 8.86. Mortality was 73 (24.7%) at 6 weeks post injury and complete TSCI, cervical spinal cord segment and the average "first week" MAP were, independent predictors of mortality. The admission ASIA impairment scale (AIS) and injury to presentation interval were predictive of AIS improvement at 6 weeks and length of hospital stay (LOHs). Conclusions: We also found that AIS at admission, level of spinal cord affected and the average first week MAP were early predictors of mortality, while the injury to presentation interval and admission AIS, predicted improvement of AIS at 6 weeks. The LOHs was seen more in patients with severe AIS at admission and those who had delayed presentation.
RESUMO
Background and Objective: Intramedullary tuberculoma (IMT) of the conus medullaris is an extremely rare tumour that constitutes a diagnostic and management challenge in a resource-limited setting. We report a case of conus medullaris, IMT in a young immunocompetent, patient with no prior clinical features of pulmonary or extra-pulmonary tuberculosis. Case Summary: The patient presented with six months history of progressive and persistent mid back pain and slight weakness of both lower limbs of 3 months duration. Physical examination revealed a well-nourished man with power of 3/5 and hyperreflexia on both lower limbs. Chest radiograph and other investigations for tuberculosis were negative. Magnetic resonance imaging (MRI) of the lumbosacral spine showed fusiform expansion of the conus medullaris, with a well circumscribed, ring enhancing, intramedullary mass straddle between T12 and L1. Patient had gross total resection with no intraoperative monitoring assistance and no post-operative worsening of neurological function. Histology showed granulomatous lesion with central caseation in keeping with a tuberculoma. Patient was commenced on post-operative anti-tuberculous therapy with physiotherapy, with full motor recovery at six months post-surgical intervention and anti-tuberculous therapy. Conclusion: Intramedullary tuberculoma can be considered as one of the differential diagnoses of intradural, intramedullary tumour of the conus, even in immunocompetent individual with no clinical features of tuberculosis.
