Background and Objectives: Arteriovenous malformations (AVMs) are abnormal connections between arteries and veins, lacking a normal capillary network. Seizures are a common clinical manifestation in patients with brain AVMs, ranking as the second most frequent presentation. The objective of this study was to evaluate the dynamics of seizure activity in patients with brain AVMs following surgical treatment. Materials and Methods: This study included 27 patients with brain AVMs who underwent microsurgical AVM resection for symptomatic epilepsy. All surgical interventions were performed at JSC “National Centre for Neurosurgery” between 2008 and 2020. Results: Over an average follow-up period of 98.07 ± 45.6 months, 82 patients with brain AVMs underwent open microsurgical resection at the National Centre for Neurosurgery. Among them, 27 patients presented with seizures and had complete follow-up information, qualifying them for inclusion in this study. The participants had a mean age of 32.59 ± 9.06 years, with 13 of them being women. The Spetzler–Martin grading system was used to classify the AVMs: 6 patients had grade 1, 13 had grade 2, 7 had grade 3, and 1 had grade 4. More than half of the patients experienced generalized seizures. Microsurgical removal of the AVMs resulted in seizure remission for all patients. Only one patient experienced postoperative hemorrhage during the follow-up period. Additionally, one patient developed acute postoperative anemia, which resolved with a favorable outcome. Conclusions: Microsurgical resection of brain AVMs, when performed with careful patient selection, leads to a significant reduction in seizure activity. It is a safe and effective treatment option for symptomatic epilepsy associated with brain AVMs.

Background: Rupture of intracranial aneurysms (RIA) leads to subarachnoid hemorrhage (SAH) with severe consequences. Although risks for RIA are established, the results vary between ethnic groups and were never studied in Kazakhstan. This study aimed to establish the risk factors of RIA in the Kazakh population. Methods: Retrospective analysis of 762 patients with single IAs, who attended the neurosurgical center from 2008 until 2018, was conducted. Demographic characteristics, such as age, sex, smoking status, and hypertension were considered. Descriptive and bivariate analyses were performed. A multivariable logistic regression model was built to identify factors correlated with RIA. Results: The mean age of participants was 48.49 ± 0.44 years old. The majority (68.37%) of IAs have ruptured. Of the ruptured aneurysms, 43.76% were < 6 mm, and 38.39% were located on the anterior cerebral and anterior communicating arteries (ACA). Logistic regression model indicates younger age group (16–40 years), smoking, having stage 3 hypertension, smaller IA size and its location on ACA increase the odds of rupture. Conclusions: This study has revealed that younger, smoking patients with stage 3 arterial hypertension are at higher risk for RIA. Small aneurysms (< 6 mm) and location on ACA had increased odds of rupture, while larger aneurysms on internal carotid arteries had lower odds.

Neurosurgery education in Kazakhstan has 55 years of history. The first neurosurgery department was established in 1964 in the city of Almaty, South Kazakhstan (the former capital of Kazakhstan). The department was headed by the pioneer of Kazakhstani neurosurgeons, Prof. Yevgeniya Azarova. A new neurosurgery education system was adopted after a while. To date, 4 medical universities and 1 neurosurgical center in Kazakhstan have a neurosurgery department that prepares around 10 neurosurgeons annually. The country’s populations are currently served by more than 300 neurosurgeons. However, isolated regions lack neurosurgical services and a specialized medical workforce. Urbanization results in inequality of receiving medical care among rural and regional inhabitants. To develop and strengthen the neurosurgery services, the National Center for Neurosurgery was opened in the heart of the country. The center has placed great importance on the development of neurosurgery and neurosurgical education in Kazakhstan. The World Federation of Neurosurgical Societies, European Association of Neurosurgical Societies, Asian Congress of Neurosurgeons, and International Society for Pediatric Neurosurgery have held many international meaningful events on neurosurgery at the center. Opened in 2008, the neurosurgery center has prepared 41 neurosurgeons in the residency program. This article seeks to provide readers with an understanding of the state of neurosurgery education in Kazakhstan and its development history.
