CONFECÇÃO DE BIOMODELOS PARA PACIENTES RECÉM-NASCIDOS E CRIANÇAS MAIORES COM COARCTAÇÃO DA AORTA

Abstract

Coarctation of the aorta (CoA) is a congenital disease in which there is narrowing of the aorta in its descending thoracic portion. There are procedures that are less-invasive such as balloon dilation, which is the insertion and insufflation of a device into the aorta to open the vessel, and stent implantation in which it is possible to keep the vessel opened in a certain diameter, the most commonly used procedure. There are factors that must be taken into account when selecting the stent model to be used, as well as: the implant mechanism; the geometry; the type of mesh formed by the metal rods; their structural design and their metallic composition. The applications of additive manufacture or 3D printing, focusing on the development of "physiological models" from DICOM files from computerized tomography of patients with congenital CoA generate biomodels as close as possible to the patient's anatomy. With this, the surgeons can discuss in detail which will be the best treatment to that patient. The analysis of the region with malformation before the intervention can significantly reduce future complications.
