Abstract：
BACKGROUND: The use of three-dimensional(3D) printing is broadly across many medical specialties. It is an innovative, and rapidly growing technology to produce custom anatomical models and medical conditions models for medical teaching, surgical planning, and patient education. This study aimed to evaluate the accuracy and feasibility of 3D printing in creating a superficial femoral artery pseudoaneurysm model based on CT scans for endovascular training.
METHODS: A case of a left superficial femoral artery pseudoaneurysm was selected, and the 3D model was created using DICOM files imported into Materialise Mimics 22.0 and Materialise 3-Matic software, then printed using vat polymerization technology. Two 3D-printed models were created, and a series of comparisons were conducted between the 3D segmented images from CT scans and these two 3D-printed models. Ten comparisons involving internal diameters and angles of the specific anatomical location were measured.
RESULTS: The study found that the absolute mean difference in diameter between the 3D segmented images and the 3D printed models was 0.179±0.145 mm and 0.216±0.143mm, respectively, with no significant difference between the two sets of models. Additionally, the absolute mean difference in angle was 0.99±0.65° and 1.00±0.91°, respectively, and the absolute mean difference in angle between the two sets of data was not significant. Bland-Altman analysis confirmed a high correlation in dimension measurements between the 3D-printed models and segmented images. Furthermore, the accuracy of a 3D-printed femoral pseudoaneurysm model was further tested through the simulation of a superficial femoral artery pseudoaneurysm coiling procedure using the Philips Azurion7 in the angiography room.
CONCLUSIONS: 3D printing is a reliable technique for producing a high accuracy 3D anatomical model that closely resemble a patient\'s anatomy based on CT images. Additionally, 3D printing is a feasible and viable option for use in endovascular training and medical education. In general, 3D printing is an encouraging technology with diverse possibilities in medicine, including surgical planning, medical education, and medical device advancement.

摘要：
背景：三维（3D）打印的使用广泛涉及许多医学专业。这是一种创新，以及快速发展的技术，以生产用于医学教学的定制解剖模型和医疗条件模型，手术计划,和病人的教育。本研究旨在评估3D打印在建立基于CT扫描的股浅动脉假性动脉瘤血管内训练模型中的准确性和可行性。
方法：选择1例左股浅动脉假性动脉瘤，使用导入MaterialiseMimics22.0和Materialise3-Matic软件的DICOM文件创建3D模型，然后使用大桶聚合技术打印。创建了两个3D打印模型，并在CT扫描的3D分割图像和这两个3D打印模型之间进行了一系列比较。测量了涉及特定解剖位置的内径和角度的十次比较。
结果：研究发现，3D分割图像与3D打印模型之间的直径绝对平均差为0.179±0.145mm和0.216±0.143mm，分别,两组模型之间没有显著差异。此外,角度的绝对平均差为0.99±0.65°和1.00±0.91°，分别,两组数据之间的绝对平均角度差异不显著。Bland-Altman分析证实了3D打印模型和分割图像之间的尺寸测量高度相关。此外，通过在血管造影室使用PhilipsAzurion7模拟股浅动脉假性动脉瘤盘绕手术,进一步检验了3D打印股动脉假性动脉瘤模型的准确性.
结论：3D打印是一种可靠的技术，可以根据CT图像生成与患者解剖结构非常相似的高精度3D解剖模型。此外,3D打印是用于血管内训练和医学教育的可行和可行的选择。总的来说,3D打印是一项令人鼓舞的技术，在医学领域具有多种可能性，包括手术计划,医学教育,和医疗器械的进步。
