“…Recent advances in 3D printing technology have led to the development of new resources, making the use of a wide variety of materials from plastic to metals possible. It is possible to directly 3D print hollow flexible models, which is a one-step process; therefore, it is faster and more accurate than the commonly used lost wax technique [27]. The choice of the 3D printer depends on the application.…”

The endovascular technique has led to a revolution in the care of patients with vascular disease; however, acquiring and maintaining proficiency over a broad spectrum of procedures is challenging. Three-dimensional (3D) printing technology allows the production of models that can be used for endovascular training. This article aims to explain the process and technologies available to produce vascular models for endovascular training, using 3D printing technology. The data are based on the group experience and a review of the literature. Different 3D printing methods are compared, describing their advantages, disadvantages and potential roles in surgical training. The process of 3D printing a vascular model based on an imaging examination consists of the following steps: image acquisition, image post-processing, 3D printing and printed model post-processing. The entire process can take a week. Prospective studies have shown that 3D printing can improve surgical planning, especially in complex endovascular procedures, and allows the production of efficient simulators for endovascular training, improving residents’ surgical performance and self-confidence.

“…In planning surgical procedures, a 3D model conveys key anatomical relationships to surgeons in a way that 2D (two-dimensional) images on a computer currently do not. 1–9 In addition to surgical planning, 3D printing technology has also been used to create patient-specific implantable scaffolds for biological grafts. 10–11 …”

Purpose Three dimensional (3D) printing of anatomic models for complex surgical cases improves patient and resident education, operative team planning, and guides surgery. Our group intends to describe two additional dimensions. Description The process of 5-dimensional printing was developed for surgical planning. Pretreatment computed tomography and positron emission tomography scans were reformatted and fused. Selected anatomy from these studies along with post treatment computed tomography and magnetic resonance images were co-registered and segmented. This fused anatomy was converted into stereolithography files for 3D printing. Evaluation A patient presenting with a complex thoracic tumor was selected for 5-dimensional printing. 3D and 5-dimensional models were prepared to allow surgical teams to directly evaluate and compare the added benefits of information provided by printing in 5dimensions. Conclusions Printing 5-dimensional models in patients with complex thoracic pathology facilitates surgical planning, selecting margins for resection, anticipating potential difficulties, teaching for learners, and education for patients.
