ABSTRACT
Background: Ruptured cerebral artery aneurysms (RCAA) are devastating diseases with high morbidity and mortality rates if not promptly managed. In Nigeria, access to timely neurosurgical services remains a challenge and aneurysm coiling is still not possible in virtually all centres in Nigeria. The aim of this study is to report on our 9 years' experience with clipping of cerebral aneurysm and on the attendant clinical outcomes. Methodology: A retrospective analysis of all consecutive operated RCAA between March 2012 and June 2021 was conducted. Patients' demographic parameters, World Federation of Neurosurgical Societies (WFNS) grade, Hunt and Hess (HH) grade, aneurysm location, timing of surgery and outcome were analysed. Outcome was measured using Glasgow Outcome Scale (GOS) score. Results: A total 29 were included in the study. The most common age group affected was between 50-59 years. RCAA were mainly in the region of the middle cerebral artery and posterior communicating artery (PComA) territories. All the patients presented after 24 hours of the ictus. Two (6.9%) patients had multiple aneurysms. Early clipping (<72hours after presentation) was possible in 8 (27.6%) patients. At least one episode of a rebleed occurred in 19 (65.5%) patients prior to surgery. Mortality rate was 17.2%. None of the patients with PComA aneurysm died. The patients' pre-operative WFNS and HH grades were significantly associated with GOS. Conclusion: Modifiable factors like under diagnoses, delayed referral, cultural belief and financial challenges may account for the low number of patients presenting for neurosurgical care. The possibility of a sizeable number of patients dying due to these factors is a strong possibility for the low number of patients presenting for neurosurgical care.
ABSTRACT
OBJECTIVES: Monitored conscious sedation combined with spinal anaesthesia (MCSS) to repair myelomeningocoele (MM) has received little attention in the literature. It has the potential of rapid postoperative recovery, minimal perioperative morbidity and probable reduced cost of management. The objective of this study was to prospectively analyze the safety and effectiveness of MCSS during repair of MM in infants. MATERIALS AND METHODS: This series consists of a prospective study of the clinical features, anaesthetic technique and perioperative outcome of 30 infants who underwent repair of MM under MCSS. The procedure was considered safe and effective if no event occurred during anaesthesia resulting in the procedure being aborted or postoperative complication related to the anaesthetic technique. RESULTS: There were 19 males and 11 females. The median age of the patients was 3 months ranging from 2 days to 12 months. The study included patients with lumbar (four patients), lumbosacral (23 patients) and sacral (three patients) MM. None of the cases needed to be converted to general anaesthesia. The mean duration of surgery was 56.4 min (median = 55 min; range of 40-85 min). There was no significant perioperative morbidity or mortality. CONCLUSIONS: The prevailing adverse socioeconomic status, health undermining religious belief, paucity of neurosurgeons/neuroanaesthetists and inadequate facilities in sub-Saharan Africa delay the presentation and surgical intervention of patients with MM. This technique is useful if the exclusion criteria are adhered to and should be considered as one of the armamentarium in economically challenged environments as it is probably cheaper than general anaesthesia.
