Les méningiomes sont des tumeurs bénignes extra parenchymateuses développées aux dépens des villosités arachnoïdiennes. Ils tirent leur gravité de leur localisation dans des zones hyperfonctionnelles. Le but de cette étude est d’évaluer la prise en charge des méningiomes intracrâniens depuis la réhabilitation du service de neurochirurgie en 2007. Les auteurs rapportent une série rétrospective portant sur 50 patients admis et opérés d'un méningiome intracrânien d'octobre 2007 à Juin 2013 dans leur service. Ont été inclus les patients ayant un dossier complet. Les patients étaient âgés de 08 à 70 ans avec une moyenne d’âge de 47,3 ans, 68% avaient plus de 40 ans. La sex-ratio était de 0,76. Les manifestations cliniques étaient essentiellement l'hypertension intracrânienne (46%), le déficit moteur (30%) et la comitialité (48%). La tomodensitométrie cérébrale était réalisée chez 41 patients et l'IRM chez 23. Le méningiome était localisé sur la convexité chez 24 patients. L'imagerie postopératoire immédiate était réalisée chez 15 patients. L'exérèse a consisté dans 44% des cas à un Sympson II, et dans 30% des cas à un Sympson III. L'anatomopathologie a conclu à une prédominance du type méningothélial (38%) et 60% des méningiomes étaient de grade I selon la classification de l'O.M.S. Aucun patient n'a bénéficié d'une radiothérapie. La mortalité était de 16%. Les pays d'Afrique subsaharienne continuent d'accuser un retard malgré les efforts réalisés dans les domaines diagnostic et thérapeutique des méningiomes intracrâniens. Le pronostic s'est considérablement amélioré à mesure de l'amélioration du plateau technique dans notre pays.
Introduction: Africa has many untreated neurosurgical cases due to limited access to safe, affordable, and timely care. In this study, we surveyed young African neurosurgeons and trainees to identify challenges to training and practice.Methods: African trainees and residents were surveyed online by the Young Neurosurgeons Forum from April 25th to November 30th, 2018. The survey link was distributed via social media platforms and through professional society mailing lists. Univariate and bivariate data analyses were run and a P-value < 0.05 was considered to be statistically significant.Results: 112 respondents from 20 countries participated in this study. 98 (87.5%) were male, 63 (56.3%) were from sub-Saharan Africa, and 52 (46.4%) were residents. 39 (34.8%) had regular journal club sessions at their hospital, 100 (89.3%) did not have access to cadaver dissection labs, and 62 (55.4%) had never attended a WFNS-endorsed conference. 67.0% of respondents reported limited research opportunities and 58.9% reported limited education opportunities. Lack of mentorship (P = 0.023, Phi = 0.26), lack of access to journals (P = 0.002, Phi = 0.332), and limited access to conferences (P = 0.019, Phi = 0.369) were associated with the country income category.Conclusion: This survey identified barriers to education, research, and practice among African trainees and young neurosurgeons. The findings of this study should inform future initiatives aimed at reducing the barriers faced by this group.
Les kystes arachnoïdiens intrasellaires sont des malformations bénignes. La localisation intrasellaire est extrêmement rare de l’ordre de 3%. Leur physiopathologie est encore mal élucidée. Nous rapportons un cas de kyste arachnoïdien intrasellaire à expansion suprasellaire dont la prise en charge avait consisté en une fenestration endoscopique par voie transsphénoïdale. Les aspects épidémiologiques, cliniques, physiopathologiques, radiologiques, thérapeutiques et évolutifs ont été analysés. Les procédures neuroendoscopiques sont de plus en plus utilisées pour la prise en charge chirurgicale. Leur pronostic est bon, et la récidive fréquente même après plusieurs années d’évolution.
Rationale: Interventional neurovascular procedures are effective in lowering the burden of mortality and complications resulting from aneurysmal subarachnoid hemorrhage (aSAH). Despite the wide uptake of interventional neurovascular procedures in high-income countries, access to care in low- and middle-income countries remains limited, and little is known about accessibility in Africa. In this survey, we decided to assess access to diagnostic tools and treatment of aSAH in Africa.Methodology: A Google form e-survey was distributed to African neurosurgery centers accepting responses from January 4th to March 21st 2021. Data on accessibility to diagnostic tools, treatment methodologies, and interventional neuroradiology personnel in African centers were collected. Ninety five percent confidence intervals were computed for each variable.Results: Data was received from 36 neurosurgical centers in 16 African countries (16/54, 30%). Most centers were public institutions. Ninety four percent of the centers had the necessary resources for a lumbar puncture (LP) and a laboratory for the diagnosis of aSAH. Most centers had at least one computed tomography (CT) scanner, 81% of the centers had access to CT angiography and some had access to conventional angiography. Forty seven percent of the centers could obtain a head CT within 2 h of presentation in an emergency. Sixty one percent of centers provided clipping of intracranial aneurysms whilst only 22% of centers could perform the endovascular treatment. Sixty four percent of centers did not have an endovascular specialist.Conclusion: This survey highlights health inequity in access to endovascular treatment for aSAH. Lack of diagnostic tools to identify an aneurysm and a shortfall of qualified endovascular specialists are prime reasons for this. Our findings can inform health system strengthening policies including the acquisition of equipment and capacity building in Africa.
