| Popis: | Background. Valve-sparing aortic root replacement with aortic valve reimplantation is a rapidly developing method of treatment of ascending aortic aneurysm. The improvement of the results of this method is inextricably linked with the understanding of the relationships between the initial functional and planimetric characteristics of the valvular-aortic complex, the technical aspects of the reimplantation procedure and the results obtained.Objective. To search and analyze previously little-studied factors — the planimetric characteristics of the aortic valve and the aortic root.Design and methods. High-precision assessment of the planimetry of the aortic flaps requires precision visualization methods and subsequent creation of virtual three-dimensional models. The creation of high-precision reconstructions became possible due to the introduction of specialized computer-aided design environments into clinical practice. Due to the technical complexity, none of the known methods has previously been used to accurately measure all the structures of the aortic root in a large group of patients. Simplification, acceleration of reconstruction construction, as well as scaling of this technique remain unresolved tasks.Results. The main result of this work is the development of an algorithm of segmentation of the aortic root and the construction of a high-precision three-dimensional model of the aortic valve, as well as the practical implementation of an algorithm for determining main planimetric parameters of the aortic root with the possibility of scaling to a large group of patients.Conclusion. The method makes it possible to construct a high-precision three-dimensional reconstruction of the internal structures of the aortic root within a few hours and is valuable both for determining the tactics and technical features of surgical treatment of the patient, and for studying the effect of the anatomy of the aortic root on the development of recurrence of aortic insufficiency after valve-sparing surgery. |
