Global Neurosurgical Challenges: A Focus on Central Asia.

OBJECTIVE: To evaluate the current state of neurosurgical care in Central Asia, identify the challenges and advancements, and propose recommendations to improve neurosurgical capabilities and access in Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, and Uzbekistan. METHODS: A comprehensive review of the neurosurgical infrastructure, availability of neurosurgeons, technological advancements, and healthcare policies in the five Central Asian countries. Analysis included published literature, healthcare reports, and expert opinions to assess the state of neurosurgical care and identify areas for improvement. RESULTS: Significant variation in neurosurgical care was observed across the region. Kazakhstan showed notable advancements, including an increased number of neurosurgeons and progress in specialized fields such as vascular neurosurgery and brain tumor management. Other countries, like Uzbekistan, Tajikistan, and Kyrgyzstan, made strides in improving neurosurgical care but still faced substantial challenges. Common issues included a shortage of neurosurgeons, limited facilities, and inadequate access to modern technology. The lack of research data further highlighted the need for urgent intervention. CONCLUSIONS: To enhance neurosurgical care in Central Asia, a multipronged approach involving targeted investments, policy reforms, international collaborations, and knowledge sharing is recommended. This includes establishing specialized neurosurgical training programs and fellowships, investing in infrastructure and technology, fostering international collaborations for training and research, introducing early neurosurgery education in medical schools, improving access to online education resources, and promoting telemedicine for consultations and follow-up care. These measures are necessary to expand access to essential neurosurgical care and improve outcomes in the regions.

Advocacy for Epilepsy Surgery in Africa: Moroccan Experience of 132 Cases.

BACKGROUND: In Africa, epilepsy is a real burden. Temporal lobe epilepsy is the most common drug-resistant focal epilepsy disorder, and temporal lobectomy is the most common effective treatment for patients with drug-resistant epilepsy. OBJECTIVE: We aim to highlight the Moroccan experience in epilepsy surgery and to ascertain its long-term outcome. Through the results of surgical treatment in our series, we hope to raise awareness of the need for epilepsy surgery in Africa and contribute to its development. METHODS: We present a retrospective study of 132 patients who underwent surgery for epilepsy from January 2005 to December 2021 at our institution. The presurgical evaluation was based on clinical screening, interictal electroencephalography, video-electroencephalography, neuropsychological tests, magnetic resonance imaging, and positron emission tomography in some cases. Data are presented as the median and ranges. For all analyses, P values <0.05 were considered statistically significant. RESULTS: Our series includes 132 patients (69 males; 52.27%); the median age at surgery was 24 years (range, 1-64). One hundred and fifteen patients (87%) were operated on for temporal lobe epilepsy, of whom 98 (85%) had anterior temporal lobectomy and 17 (15%) had lesionectomy. Seventeen patients (13%) were operated on for extratemporal epilepsy, of whom 4 had lesionectomy, 7 functional hemispherotomy, and 5 Gamma Knife stereotactic radiosurgery. Our postoperative outcomes 3 months after surgery found 113 patients (85.6%) seizure-free (Engel class I), 16 with Engel class II (12.1%), and 3 with Engel class III (2.3%) in temporal lobe epilepsy. In extratemporal lobe epilepsy, 12 patients (70.5%) showed Engel class I, seizure-free, 4 Engel class II (23.5%), and 1 Engel class III (6%). CONCLUSIONS: These results confirm that most patients with drug-resistant epilepsy may benefit from surgical treatment without submitting to preoperative invasive explorations. This finding should help develop epilepsy surgery widely in Africa.

Persistent flow inside the Woven EndoBridge at angiographic follow-up: A multicenter study.

BACKGROUND: The occurrence of persistent intra-device filling (BOSS 1, using the Bicêtre Occlusion Scale Score (BOSS)) in aneurysms treated with a Woven Endobridge (WEB) device is infrequent based on angiographic follow-up. To date, three monocentric case series were published studying BOSS 1 cases. Through a multicenter retrospective study, we aimed to report the incidence, and risk factors of intra-WEB persistent filling. METHODS: We reached out to European academic centers that treat patients using WEB devices and requested de-identified data of patients treated with a WEB device and underwent angiographic follow-up, at least 3 months after embolization, to assess the BOSS 1 occlusion score. We compared baseline characteristics, treatment modalities, and aneurysm data of the included BOSS 1 patients with those of a control group consisting of non-BOSS 1 patients (n = 116) who had an available angiographic follow-up. Univariable and multivariable models were employed for analysis. RESULTS: Among the pooled sample of 591 aneurysms treated with WEB, the rate of persistent flow (BOSS 1) at angiographic follow-up was 5.2% (n = 31 out of 591), performed after an average of 8.7 ± 6.3 months. In the multivariable-adjusted analysis, dual antiplatelet therapy in the postoperative period (adjusted odds ratio [aOR] 4.3 [95% CI 1.3-14.2]), and WEB undersizing (aOR 10.8 [95% CI 2.9-40]) were independently associated with a BOSS 1 persistent flow result. CONCLUSION: Persistent blood flow within the WEB device during angiographic follow-up (BOSS 1) is an uncommon occurrence. Our findings indicate that post-procedural dual antiplatelet therapy and undersizing of the WEB device are independently associated with the presence of BOSS 1 at follow-up.

State of Neurosurgical Education in Africa: A Narrative Review.

BACKGROUND: There is no comprehensive report of neurosurgery postgraduate education in Africa. This narrative review aimed to map out the landscape of neurosurgery training in Africa and highlight similarities and differences in training. METHODS: The keywords "neurosurgery," "education," and "Africa" were searched on PubMed and Google Scholar from inception to January 17, 2021. Next, a complementary hand search was conducted on Google using the keywords "neurosurgery," "residency," and the individual African countries in English and official languages. The relevant data were extracted and compiled into a narrative review. RESULTS: A total of 76 African training programs that recruit more than 168 trainees each year were identified. Less than half (40.7%, n = 22) of African countries have at least 1 neurosurgery training program. Egypt (n = 15), Algeria (n = 14), and Nigeria (n = 10) have the highest number of training programs, whereas Algeria (0.33), Egypt (0.15), and Libya (0.15) have the highest number of training programs per 1 million inhabitants. The College of Surgeons of East, Central, and Southern Africa has 16 programs in 8 countries, whereas the West African College of Surgeons has 17 accredited programs in 3 countries. The duration of training varies between 4 and 8 years. There is limited information available in the public domain and academic literature about subspecialty fellowships in Africa. CONCLUSIONS: This review provides prospective applicants and African and global neurosurgery stakeholders with information to advocate for increased investment in African neurosurgery training programs.
