Abstract
LOPEZ, Alesio E. et al. Implementation of three-dimensional printed models in hepatic surgery. Rev. argent. cir. [online]. 2022, vol.114, n.3, pp.262-268. ISSN 2250-639X. http://dx.doi.org/10.25132/raac.v114.n3.1623.
Three-dimensional (3D) printing is the construction of a solid structure from a digital model. 3D reconstruction was performed using contrast-enhanced computed tomography scan, and 3D-printed models were built based on the main anatomic structures of the liver. 3D-printed models were used in two patients with indication of surgery; one woman with inherited thrombocytopenia and liver metastases from colorectal adenocarcinoma with no response to chemotherapy, and one man with chronic liver infection and hepatocellular carcinoma. The implementation of 3D printing technology was very useful, as it facilitated the understanding of the spatial relationships among the anatomical structures in both cases. In our experience, the use of 3D-printed models was very useful for preoperative planning and for understanding the anatomic landmarks. The model was built in 7 days, with a cost of 380 dollars which is elevated in our environment.
