Since its introduction, ETV has been a safe alternative to ventriculoperitoneal shunt (VP shunt), which has a high complication rate with significant socio-economic consequences. The authors report the results of ETV performed in the neurosurgical department of FANN teaching hospital in Dakar. <strong>Methods: </strong>This retrospective study presents the results of ETV performed in 513 patients with hydrocephalus of various etiologies, ranging from February 2010 to February 2018. We have included in our series from 2010 to 2016, all patients with clinically revealed non-communicating hydrocephalus followed by a brain computed tomography (CT) scan or brain magnetic resonance imaging (MRI) and who have benefited from an ETV, in which the ETV Success Score was evaluated. <strong>Results:</strong> The mean age of our patients was 14.10 years, with 298 (58%) males. The clinical symptomatology varied in both children and adults and manifested in children as macrocrania in 67.8% of the patients, while in adults, it manifested as raised intracranial pressure (ICP) in 87.5% of patients. A brain CT scan was performed in 461 (89.86%) of patients. The causes of hydrocephalus were dominated in 49% of patients by malformative pathologies, followed by tumors in 41% of patients, infections in 2.33% of patients, and normal-pressure hydrocephalus in 3.8% of patients. During the postoperative period, we found 21.41% of various complications. <strong>Conclusions:</strong> The findings in our series were compared to those in the literature and were satisfactory, thus proving the effectiveness and safety of ventriculocisternostomy in our department. In resource-limited countries, ETV can be performed with good results and less mortality and morbidity.展开更多

The authors report in a developing country a case of immunocompetent patient with left unilateral frontal headache, associated with left eye ptosis. The Brain CT Scan revealed frontal sinus aspergillosis. She underwent surgery followed by itraconazole cure. The outcome is successful after a period of 14 months with resolution of symptomatology. Anatomopathological examination confirmed aspergillosis. They share their experience of management of this disease in a country where neurosurgery is very young specialty and where molecules against aspergillosis are not available.展开更多

This study will discuss the epidemiological, clinical, biology and radiology assessment, the etiologies, the therapeutic and evolutionary aspects of this condition in children in Senegal. Patients and Methods: 113 children aged between 15 months and 18 years were managed in a 10 years period (from January 2005 to July 2015) for a non-traumatic spinal cord compression (average 8.3 years). Results: There was 66 males (58%) and 47 females (42%) with sex ratio of 1.40. The main reasons for consultation were spinal deformity (90 %). The syndrome was complete in 52 patients (46%) and incomplete in 61 patients (54%). Plain radiography performed in 63 patients. The CT scan was performed in 21 patients and myelography performed in 4 patients. MRI was performed in 22 patients. There was intradural extramedullary process (33.33%), the extradural lesions (14.28%) and intramedullary process (28.57%). Dorsal lesions were predominant (46%) followed by the lumbar spine (27%). The majority of the etiology was Pott’s disease (80%) followed by tumors (17%). Spondylitis to banal germs (2%) and parasitic spinal cord compression (1%) were rare. The histology of 6 patients was revealed 5% neurofibroma Type II, 5% extramedullary intradermal arachnoid cyst, 5% intramedullary arachnoid cyst with cytochemistry of the CSF—like content, 5% Anaplastic pilocytic astrocytoma, 5% ganglioneuroma I terminal cone and 5% meningothelial meningioma. Pott’s disease has been cured by TB chemotherapy associated with a corset in 88.89% of cases. 2 patients of this group had benefited fixation after laminectomy. 68% of the patients had a favorable recovery, and 20% had completely recovered after an average of 7 months of treatment and three (3) patients had died. The compression by bilharzias is be cured by myelotomy and praziquantel with a favorable outcome. We have 94.74% decompressive laminectomy or laminotomy with tumor resection and four (4) Patients of this group benefited fixation;the patients who had intramedullary tumor benefited myelotomy and tumor resection;3 patients in this group had benefited fixation after laminectomy 58% of patients had good recovery and 1 pateint had died. Conclusion: In Africa, particularly in the tropics, Pott’s disease remains the first etiology followed by vertebra-medullary tumors for no traumatic spinal cord compression of child.展开更多

The objective of this study was to determine the frequency and report the modalities of management. Methodology: This study on lumbosciatic disc disease was carried out in the neurosurgery department of the University Hospital Center (CHU), la Renaissance in N’Djamena. It covered a period of 12 months (from September 2019 to August 2020). A descriptive and an analytical approach were used. The variables studied were epidemiology, clinic, radiology and therapy. Results: the results showed that LSD represented 14.7% of the reasons for consultation in neurosurgery. The average age was 45.8, and to some extent, it ranges between 18 and 76. Lifting was the main reason behind lumbosciatic disc disease with 35.9% of cases, followed by a sedentary life style which represents 30.8%. Lumbosciatica L5 was noted in 49.4%. Obesity and overweight were significant risk factors (P = 0.02) reported in 59% of cases. Motor and sensory deficits were observed in 14.8% and 17.3% of cases, respectively. CT of the lumbar spine was performed in 91% and MRI in 28.9%. The L4-L5 disc herniation represented 74.3% of cases, with a lateral location in 44.2% and L5 radicular impingement in 30.8%. Conservative treatment was instituted in 87.2% and surgical treatment in 12.8% of cases. Conclusion: LSD is caused by a sedentary lifestyle, physical work and overweight. Surgery deals with complicated cases and cases not responding to conservative treatment.展开更多

This work aims to report the experience the of Fann’s neurosurgery department in treating certain spinal pathologies by vertebroplasty and kyphoplasty. Methods: During a 3-year period from July 1, 2019 to July 31, 2022, we conducted a retrospective, descriptive and analytical study, including patients who underwent vertebroplasty or kyphoplasty for dorsolumbar spinal pathology. Results: The mean age of the 13 patients in our study was 51.61 years. Female gender was predominant in 62% (n = 8). The context of spontaneous onset was found in six patients. Nine patients had a VAS (visual analogue scale) ≥ 8 (69.23%). On clinical examination, all patients had a syndrome without neurological deficits. 84.61% of patients had a CT scan (n = 11). The dorsolumbar hinge was most affected with 53.85% of cases. Seven patients had a vertebral compression of between 25% and. The average degree of kyphosis was 8˚ and seven patients had a degree of kyphosis ≥ 10˚. Tumour aetiology accounted for 46.15% of cases. Kyphoplasty was performed in 61.53% (n = 9) of the cases and vertebroplasty was performed in 38.47% (n = 4) of the patients. Kyphoplasty was associated with biopsy in two cases and with osteosynthesis in one patient. Vertebroplasty was always associated with a biopsy. The evolution was favourable with a significant reduction in pain and vertebral kyphosis. The mean VAS decreased from 8.15 to 0.69 three months after treatment and the mean kyphosis decreased from 8˚ to 2˚. Conclusion: Kyphoplasty and vertebroplasty as percutaneous techniques allow consolidation of the vertebral body and pain relief. Kyphoplasty alone not only reduces pain but also restores the height of the compacted vertebral body.展开更多
