Introduction: Studies on age differences of arterial trauma (AT) carry significant methodological differences in terms of selection of the most appropriate age classification. Aim: This study aims to verify the most optimal age classification when comparing clinical patterns of the civil AT. Material and methods: 222 AT patients were identified from the Lviv Clinical Regional Hospital. In each case the following clinical patterns were identified: patient age, etiology, mechanism, AT type, topography, diagnostics mode, treatment type. Patients were distributed using six age classifications (Erikson 1950, UN 1989, Quinn 1994, Craig 2000, WHO physical activity recommendations 2010, by decades of life). Generalized linear models (GLMs) were created, with age distributions as predictors and clinical patterns as dependent factors. Akaike information criterion (AIK) was used to compare the quality of statistical sets. Results and discussion: Six GLMs were obtained, in each age of them age classifications were compared using the AIK. Rating list of age classifications was developed (starting with the most appropriate and ending with the least appropriate): E. Erikson (1950) → V. Quinn (1994) → G. Craig (2000) → UN (1989) → Decades → WHO (2010). Conclusions: Human development classifications may be preferable in assessing the age differences of AT in patients of wide range.
Objective(s). To create a normal heart virtual model and visualize the anatomical position of the right and left chambers. Methods. The material for the investigation was cardiac CT scan results of a young healthy man. From these data, a three-dimensional heart model was created and anatomical position of the right and left chambers investigated. Results. Three-dimensional model of a normally formed, normally located heart was created. Segmentation, rotation of the virtual model, virtual horizontal dissection at the level of the middle of the interventricular septum were carried out, the created model was rotated in virtual reality. It was found that in the anatomically correct position the right chambers of the heart are located in front, and the left chambers are located behind. Conclusion. Virtual heart reconstruction reproduces digital data taken from a living person, so virtual reality shows the functioning structure of the heart and its chambers. In the anatomical position of the heart, the right atrium and ventricle are located ventrally, and the left atrium and ventricle are located dorsally. It is advisable for morphologists, cardiologists, and surgeons to take into account the identified discrepancies between the terms and the actual location of the heart chambers.
Цель работы -оценить возможности физикальных методов диагностики травм артерий (ТА) у больных разного возраста. Материалы и методы.Проанализированы данные стационарных карт 222 пациентов разного возраста с ТА, находившихся на лечении в отделении сосудистой хирургии Львовской областной клинической больницы в 1992-2019 гг. В зависимости от возраста пациентов поделили на 7 групп: младенцы (≤2 года, 4,05 %), раннее детство (3-6 лет, 0,9 %), детство (7-12 лет, 4,05 %), подростки (13-18 лет, 11,3 %), молодежь (19-40 лет, 48,6 %), зрелый возраст (41-65 лет, 24,8 %), пожилой возраст (≥66 лет, 6,3 %). Повреждение артерии диагностировали на основании абсолютных (пульсирующее кровотечение, отсутствие пульсации дистальнее места травмы, растущая гематома, дрожание или шум над местом травмы, признаки
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
