複雑な大動脈の異常の三次元印刷

Executive Industry Relevance

Complex congenital aortic anomalies present significant challenges in pre-operative planning due to limitations in 2D imaging for accurate anatomic localization. Three-dimensional (3-D) printing transforms volumetric DICOM imaging data into anatomically realistic physical models, enabling surgeons to identify vessel locations and reduce the risk of unpredictable tissue injury during complex aortic surgery. This approach supports predictive confidence in surgical decision-making and enhances translational continuity from discovery to clinical application.
