“…Dickinson et al . reported 2 cases of complex esophageal pathology where extensive 3D-printed models (in one case including esophagus and fistulous tract, spit fistula, stomach, aorta and aortic graft, trachea, veins, diaphragmatic crus, spine and ribs) helped define the surgical approach [76]. In the first patient with left pneumonectomy, aortic bypass and esophageal diversion that required esophageal endomucosal resection and gastroesophageal junction stapling, the model enabled assessment of the proximity of the esophagus to the aortic graft and pre-operative simulation and intraoperative guidance for a hybrid endoscopic-surgical approach that would otherwise not have been attempted.…”

Summary Medical 3D printing is emerging as a clinically relevant imaging tool in directing preoperative and intraoperative planning in many surgical specialties and will therefore likely lead to interdisciplinary collaboration between engineers, radiologists, and surgeons. Data from standard imaging modalities such as CT, MRI, echocardiography and rotational angiography can be used to fabricate life-sized models of human anatomy and pathology, as well as patient-specific implants and surgical guides. Cardiovascular 3D printed models can improve diagnosis and allow for advanced pre-operative planning. The majority of applications reported involve congenital heart diseases, valvular and great vessels pathologies. Printed models are suitable for planning both surgical and minimally invasive procedures. Added value has been reported toward improving outcomes, minimizing peri-operative risk, and developing new procedures such as transcatheter mitral valve replacements. Similarly, thoracic surgeons are using 3D printing to assess invasion of vital structures by tumors and to assist in diagnosis and treatment of upper and lower airway diseases. Anatomic models enable surgeons to assimilate information more quickly than image review, choose the optimal surgical approach, and achieve surgery in a shorter time. Patient-specific 3D-printed implants are beginning to appear and may have significant impact on cosmetic and life-saving procedures in the future. In summary, cardiothoracic 3D printing is rapidly evolving and may be a potential game-changer for surgeons. The imager who is equipped with the tools to apply this new imaging science to cardiothoracic care is thus ideally positioned to innovate in this new emerging imaging modality.

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.

“…Individualized 3D printed models for patient-specific anatomy are often segmented with vibrant colors in order to highlight the visual relationships between vital structures. A potential pitfall of this singular approach to 3D-printed anatomic modeling is the basic philosophy of the construction method:if it looks good, it is good(Bangeas, Tsioukas, Papadopoulos, & Tsoulfas, 2019;Bergquist, Morris, Matsumoto, Schiller, & Kim, 2019;Dickinson et al, 2015;Leng et al, 2017;Martelli et al, 2016). This viewpoint, however, does not consider the function of the structure represented, and may inadvertently provide a misrepresentation of in vivo organiza-…”

The three‐dimensional printing renaissance of individualized anatomical modeling: Are we repeating history?

Three‐dimensional (3D) printing has revolutionized individualized medicine for patient‐specific anatomical modeling and surgical planning. The surge of investigations in model creation for preoperative assessments and patient education has demonstrated improvements in both operative factors and patient satisfaction. In addition, recent technologic advances in 3D printing techniques have provided a resource to create visually pleasing models with chromatic cues for segmentation of adjacent structures. Despite these advances, an important consideration that has yet to be addressed is the quality of representation of the not only the form of structures created, but also the functional relationships of each structure. Jean François Fernel (1497–1558 AD) recognized a similar trend in anatomic innovation over 500 years ago, and sparked a series of texts that challenged the superficial anthropocentric views of the time and led to the foundation of physiologic principles that shaped modern medical philosophy. Accurately generating anatomical structures are directly related to discerning true physiologic function, and a comprehensive understanding of both is essential to hold accountability in fidelity for individualized 3D printing.
