Complex congenital aortic anomalies include diverse types of malformations that may be clinically asymptomatic or present with respiratory or esophageal symptoms. These anomalies may be associated with other congenital heart diseases. It is hard to identify the accurate anatomic vessel location from two-dimensional imaging data, such as computed tomography. As an additive manufacturing method, three-dimensional (3-D) printing can covert the acquired imaging data into 3-D physical models. This protocol describes the procedure for modeling the volumetric DICOM imaging into 3-D data and printing it as an anatomically realistic 3-D model. Using this model, surgeons can identify the vessel location of complex aortic anomalies, which is helpful for pre-operative planning and intra-operative guidance.
复杂先天性主动脉异常包括多种类型的畸形，这些畸形在临床上可能无症状，或表现为呼吸或食管症状。这些异常可能与其他先天性心脏病有关。从二维成像数据（如计算机断层扫描）中很难确定准确的解剖血管位置。作为一种增材制造方法，三维（3-D）打印可以将获取的成像数据转换为三维物理模型。本方案描述了将容积DICOM成像建模为三维数据并将其打印为解剖学逼真的三维模型的过程。使用该模型，外科医生可以确定复杂主动脉异常的血管位置，这有助于术前规划和术中指导。
