Перспективным методом хирургического лечения аневризмы корня и восходящей аорты (ВА) при неизмененных створках аортального клапана (АК) является протезирование корня и ВА с реимплантацией АК (операция Дэвида). До настоящего времени не сформулированы однозначные критерии, позволяющие сделать выбор в пользу клапаносберегающей либо клапаноуносящей операции. Главными критериями остаются результаты визуальной ревизии и выбор метода лечения на основании опыта хирурга. Цель. В эксперименте разработать прототип и методику применения устройства позиционирования створок АК, которое позволит упростить и cтандартизировать клапаносохраняющее протезирование корня аорты, улучшить результаты и повысить воспроизводимость данных операций. Материалы и методы. Трехмерное (3D) моделирование компонентов устройства выполнено в параметрической среде автоматизированного проектирования с открытым исходным кодом FreeCAD 0.20.1. Двумерные эскизы преобразовывались в трехмерные модели и экспортировались в виде файлов формата stl для 3D-печати. Твердые компоненты модели изготавливались из полимолочной кислоты (PLA-пластик), эластичные — из резиноподобного фотополимера (Dropstil F556 10 shore A) также методом 3D-печати по технологии SLA. Результаты. Устройство представляет собой 2 одинаковых кольца-измерителя переменного диаметра, соединенных между собой тремя стойками переменной длины. В верхней части каждого из креплений стоек к дистальному кольцу имеются T-образные вырезы для временного закрепления нитей-держалок, проведенных через комиссуры створок АК. Для проксимальной фиксации протеза аорты и проксимального кольца-измерителя используются 3 П-образных шва, проведенных изнутри кнаружи через фиброзное кольцо АК, проксимальную часть сосудистого протеза и взятых в турникеты. Диаметры колец-измерителей могут бесступенчато меняться в диапазоне 25–40 мм путем вращения червячного привода. С внутренней стороны устройства помещается сосудистый протез, швы-держалки, фиксированные к вершинам комиссур, фиксируются в Т-образных вырезах в верхних частях стоек. Устройство позволит менять положение точки коаптации створок, площадь коаптации и выполнять гидравлические пробы в условиях разных позиций створок, а также переменных диаметров на уровне фиброзного кольца АК и синотубулярного соединения (25–40 мм). При достижении целевой позиции точки коаптации, площади коаптации и удовлетворительного результата гидравлической пробы створки с комиссурами фиксируются внутри протеза, устройство удаляется. Заключение. Создано новое устройство для облегчения выполнения, воспроизводимости и стандартизации клапаносохраняющего протезирования АК. Полученные результаты позволят облегчить и ускорить выполнение клапаносохраняющего протезирования корня и ВА, повысить воспроизводимость методики, снизить риски осложнений.</p></abstract><trans-abstract xml:lang="en"><p>Background. A promising method of surgical treatment of aneurysms of the root and ascending aorta (AA) with unchanged aortic valve (AV) cusps is aortic valve-sparing root replacement (VSRR) with AV reimplantation (David procedure). To date, there are no clear indications to make a choice in favor of valve-replacing or valve-sparing intervention. The result of visual evaluation and the choice of treatment method based on the surgeon’s experience remains the main criteria. Objective. In the experiment to develop a prototype and method of application of the device for positioning of AV cusps, which will simplify and standardize aortic valve-sparing root replacement, improve the results and increase the reproducibility of these operations. Design and methods. Three-dimensional (3D) modeling of the device components was performed in the parametric open-source computer-aided design environment FreeCAD 0.20.1. Two-dimensional sketches were converted into three-dimensional models and exported as stl files for 3D printing. Solid components of the model were made of polylactic acid (PLA-plastic), elastic components were made of rubber-like photopolymer (Dropstil F556 10 shore A) also by 3D printing using SLA technology. Results. The device consists of 2 similar ring-sizers of variable diameter connected by three struts of variable length. In the upper part of each of the struts fastenings to the distal ring represents T-shaped cutouts for temporary locking of the suture-holders passed through the commissures of the AV cusps. For proximal locking of the aortic graft and the proximal ring-sizer, 3 U-shaped sutures are used, passed from inside to outside through the AV ring, the proximal part of the graft and taken in the tourniquets. The diameters of the ring-sizers can be varied between 25–40 mm by rotating a worm drive. A graft is placed on the inner side of the device, the suture-holders attached to the tops of the commissures are locked in the T-shaped notches in the upper parts of the struts. The device will allow changing the position of the coaptation point, coaptation square and performing hydraulic tests in different positions of the cusps, as well as variable diameters at the level of the AV ring and sinotubular junction (25–40 mm). When the target position of the coaptation point, coaptation area and satisfactory hydraulic test result are achieved, the cusps with commissures are locked inside the graft and the device is removed. Conclusion. A new device has been developed to facilitate, reproduce, and standardize VSRR. The results obtained will facilitate and accelerate the performance of VSRR, increase the reproducibility of the technique, and reduce the risks of complications.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>аневризма</kwd><kwd>аортальный клапан</kwd><kwd>воспроизводимость результатов</kwd><kwd>грудная аорта</kwd><kwd>клапаносохраняющий</kwd><kwd>реимплантация</kwd><kwd>технология</kwd><kwd>трехмерная печать</kwd></kwd-group><kwd-group xml:lang="en"><kwd>aneurysm</kwd><kwd>aortic valve</kwd><kwd>reimplantation</kwd><kwd>reproducibility of results</kwd><kwd>technology</kwd><kwd>thoracic aorta</kwd><kwd>three-dimensional printing</kwd><kwd>valve-sparing</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках плановой темы государственного задания «Разработка устройства для клапаносохраняющей коррекции аортальной недостаточности», номер ЕГИСУ 123021000152-9.</funding-statement><funding-statement xml:lang="en">The work was performed within the framework of the planned topic of the state task “Development of a device for valve-sparing correction of aortic insufficiency”, EGISU number 123021000152-9.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Хубулава Г.Г., Марченко С.П., Старчик Д.А. и др.
