Abstract
Objective: to establish the characteristics of location for cerebral aneurysms according to ethnicity in the population of Yakutia.Patients and methods. A total of 433 patients with aneurysmal hemorrhagic stroke (AHS) who had been admitted consecutively to the regional vascular center (Yakutsk) were examined. Group 1 included representatives of the indigenous ethnic groups of the Asian race in Yakutia (n=331; 33.8% of men); Group 2 comprised patients of the Caucasian race (n=102; 45.1% of men). The diagnosis was made by digital subtraction cerebral angiography (77.6%) and multislice computed tomography angiography (22.4%).Results. A total of 433 ruptured saccular aneurysms, including the latter in the anterior cerebral and anterior communicating arteries (ACAAcoA) (33.8%), middle cerebral artery (MCA) (38.7%), internal carotid artery (ICA) (21.6%), and vertebrobasilar arteries (5.8%), were diagnosed. In Group 1, the most common location for aneurysms was MCA (41.1 and 39.7% in men and women, respectively); in Group 2, that was ACA-AcoA (52.2%) in men and ICA (42.8%) in women. The ethnic groups showed significant differences in the incidence of MCA aneurysms (40.2 and 26.4% in Groups 1 and 2; respectively (p=0.014)); (odds ratio (OR = 1.866; 95% confidence interval (CI), 1.111–3.146). In Group 1, the incidence of MCA aneurysms was higher in women than in those in Group 2 (p=0.012) (OR=2.417; 95% CI, 1.155–5.141).Conclusion. The location for cerebral aneurysms differs according to ethnicity. In Yakutia among AHS patients, the most frequent location for aneurysms is MCA among indigenous Asians, while that is ACA-AcoA in Caucasian men and ICA is in Caucasian women. The incidence of MCA aneurysms is significantly higher in indigenous Asian women than in Caucasian ones.

Summary
In Yakutia among AHS patients, the most frequent location for aneurysms is MCA among indigenous Asians, while that is ACA-AcoA in Caucasian men and ICA is in Caucasian women. При изучении госпитальной стуктуры 1078 случаев инсульта установлено, что доля кровоизлияний в результате разрыва церебральной аневризмы у представителей коренных этносов Якутии значимо выше, чем у пациентов белой расы [8]. Цель исследования – установить особенности локализации аневризм сосудов головного мозга в зависимости от этнической принадлежности в популяции Якутии.
