Выполнен последовательный анализ данных КТА аорты 7-летнего периода наблюдения. Аорта разделялась на 3 сегмента, в каждом сегменте рассчитывались общий объемы аорты (ОА), объем истинного канала (ИК), объем функционирующего просвета ложного канала (ФЛК). Математически вычислялись: объем ложного канала путем разности значений объемов между ОА и ИК, объем тромбированного просвета ЛК (ТЛК) как разность ЛК и ФЛК, коэффициент тромбоза ЛК, степень раскрываемости протеза. Проведена математическая оценка превышения объема протеза.</p></sec><sec><title>Результаты</title><p>Результаты. На клиническом примере проведены моделирование полости аорты и оценка изменений объемов истинного и ложного каналов при длительном наблюдении. Проведен анализ факторов, способствующих развитию синдрома d-SINE. При сравнении объема протеза и объема зоны имплантации выявлено превышение в 234%, раскрытие протеза при этом составило 80% от должного. При использовании референтного метода, основанного на диаметре истинного просвета аорты, превышение было не столь значимым и составило 22% через год после операции и без изменений в последующий период.</p></sec><sec><title>Заключение</title><p>Заключение. Потенциально методика измерения объемов по данным КТА может применяться в качестве дополняющей к общепринятой методике, основанной на измерении диаметров, поскольку не требует дополнительных затрат от здравоохранения и имеет потенциал в плане оценки эффективности проведенного лечения и выявления предикторов осложнений в послеоперационном периоде для определения показаний к повторному оперативному вмешательству.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Purpose</title><p>Purpose. To establish the methods for estimating the volume of the true and false aortic canals applying computed tomography angiography (CTA) to a clinical case with hybrid stent-graft thoracic aorta with distal stent-graftinduced new entry associated (d-SINE) in the long-term follow-up period in comparison with a widely used technique of measuring diameters of the aorta on different levels.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. Sequential analysis of CTA in a 7-year follow-up was performed. Aorta was divided into 3 segments, in each segment total aortic volumes (AV), volume of the true canal (TC), and volume of functional lumen of the false canal (FLFC) were calculated. The following were mathematically calculated: volume of the false canal (FC) via difference in volume between AV and TC, volume of the thrombosed lumen of FC as the difference between FC and FLFC, the coefficient of FC thrombosis, the degree of stent-graft opening. Mathematical assessment of excess volume of the graft was performed.</p></sec><sec><title>Results</title><p>Results. Modelling of aortic cavity, evaluation of changes in the volumes of TC and FC during a long-term follow-up, analysis of the factors inducing the development of the d-SINE syndrome were performed. When comparing the volume of the graft and the volume of the implantation zone, an excess of 234% was found, while the opening of the graft was 80%. When using the reference method based on the diameter of the true lumen of the aorta, the excess was 22% during one-year follow-up period showing no changes subsequently.</p></sec><sec><title>Conclusion</title><p>Conclusion. Potentially, the method of measuring volumes based on CTA results can be used to complement the generally accepted method based on measuring diameters, since it does not require additional financial resources and has the potential to estimate effectiveness of treatment and identify complications predictors in the postoperative period to determine indications for reoperation. </p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>компьютерная томография</kwd><kwd>ангиография</kwd><kwd>замороженный хобот слона</kwd><kwd>анализ объема</kwd><kwd>расслоение аорты</kwd><kwd>d-SINE</kwd><kwd>хирургия дуги аорты</kwd><kwd>гибридная хирургия аорты</kwd></kwd-group><kwd-group xml:lang="en"><kwd>computer tomography</kwd><kwd>angiography</kwd><kwd>“frozen elephant trunk”</kwd><kwd>volume analysis</kwd><kwd>aortic dissection</kwd><kwd>d-SINE</kwd><kwd>aortic arch surgery</kwd><kwd>hybrid aortic arch surgery</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Благодарим директора Института экспериментальной биологии и медицины ФГБУ “НМИЦ им. акад.
