“…Previous studies have highlighted that cardiac 3D printed models reduce the risk of perioperative complications because potential challenges can be anticipated through simulating procedures on the model, such as transcatheter aortic valve replacement 9, 11. 3D printed models also allow for increased procedural efficiency, as well as improved anatomical understanding and intraoperative orientation 8, 12…”

IntroductionThe aim of this study was to assess if the complex anatomy of aortic aneurysm and aortic dissection can be accurately reproduced from a contrast‐enhanced computed tomography (CT) scan into a three‐dimensional (3D) printed model.MethodsContrast‐enhanced cardiac CT scans from two patients were post‐processed and produced as 3D printed thoracic aorta models of aortic aneurysm and aortic dissection. The transverse diameter was measured at five anatomical landmarks for both models, compared across three stages: the original contrast‐enhanced CT images, the stereolithography (STL) format computerised model prepared for 3D printing and the contrast‐enhanced CT of the 3D printed model. For the model with aortic dissection, measurements of the true and false lumen were taken and compared at two points on the descending aorta.ResultsThree‐dimensional printed models were generated with strong and flexible plastic material with successful replication of anatomical details of aortic structures and pathologies. The mean difference in transverse vessel diameter between the contrast‐enhanced CT images before and after 3D printing was 1.0 and 1.2 mm, for the first and second models respectively (standard deviation: 1.0 mm and 0.9 mm). Additionally, for the second model, the mean luminal diameter difference between the 3D printed model and CT images was 0.5 mm.ConclusionEncouraging results were achieved with regards to reproducing 3D models depicting aortic aneurysm and aortic dissection. Variances in vessel diameter measurement outside a standard deviation of 1 mm tolerance indicate further work is required into the assessment and accuracy of 3D model reproduction.

“…Some recent studies have shown the applications of 3D printing in cardiovascular disease, such as coronary artery disease, aortic and pulmonary venous valve disease 8, 9, 10, 11, 12. 3D printing technology also allows for the production of individualised cardiac stents to reduce the rate of in‐stent re‐stenosis 1…”

“…3D printed models have been used for surgical training and education (6), creation of custom airway implants (7), surgical planning for congenital heart disease (8,9), and for aortic aneurysm repair (1). Unfortunately, these applications used proprietary software (1,7,8) or expensive on-site printers and printing services (6)(7)(8)(9).…”

Using 3D printed models for planning and guidance during endovascular intervention: a technical advance

T hree-dimensional (3D) printed vascular models have been manufactured for the heart and aorta and used preoperatively for planning and testing prior to surgery (1). Creation of intracranial vessel models has been described using 3D printing indirectly to create a scaffold, which aided in creation of hollow models using a manual painting process (2). Direct manufacture of hollow small vessel models using 3D printing has not been described, and it is unknown if it is possible with existing technology, or of any clinical utility.In a complex case of multiple splenic artery aneurysms, 3D printed vascular models were successfully created using free software and low-cost Internet 3D printing services, and were used for preoperative planning and intraoperative guidance. Two models were created. The first was a hollow model of the splenic artery. The second was a solid model of the splenic artery lumen. Both models were full-size, anatomically accurate, and derived from computed tomography (CT) scan data. The models enabled a complex endovascular procedure to be practiced and refined before the actual procedure on the patient, leading to a success that preserved the patient's spleen. Case backgroundA 62-year-old female presented with multiple asymptomatic splenic artery aneurysms that had been incidentally detected on a CT scan performed during a workup for a urinary tract infection. She was asymptomatic and had no known risk factors, including portal hypertension, liver cirrhosis, or current or past pregnancy. A contrast-enhanced CT scan revealed a significantly tortuous splenic artery, having a 360° loop followed by three 180° hairpin turns. Two 2 cm aneurysms were present, located at the second and third 180° hairpin turns, respectively (Fig. 1a, 1b). A smaller, low-risk 5 mm aneurysm was also present and located in the proximal artery. Because the distal-most aneurysm was at the splenic hilum, infarction of the spleen was likely if treated with conventional transcatheter embolization (3). The patient declined conventional treatment, including splenic artery embolization and surgical splenectomy, desiring to preserve splenic function. Flow-sparing aneurysm embolization and stent-graft placement were considered, but a consensus of three board-certified interventional radiologists and a board-certified vascular surgeon determined it was ABSTRACT Three-dimensional (3D) printing applications in medicine have been limited due to high cost and technical difficulty of creating 3D printed objects. It is not known whether patient-specific, hollow, small-caliber vascular models can be manufactured with 3D printing, and used for small vessel endoluminal testing of devices. Manufacture of anatomically accurate, patient-specific, small-caliber arterial models was attempted using data from a patient's CT scan, free open-source software, and lowcost Internet 3D printing services. Prior to endovascular treatment of a patient with multiple splenic artery aneurysms, a 3D printed model was used preoperatively to test catheter equipmen...
