Utilizing 3 Dimensional Print of The Liver in Living Donor Liver Transplantation for Preoperative Evaluation

Abstract

Objectives: To obtain a liver prototype by using a 3 dimensional printer for preoperative evaluation of vascular structures hepatic artery, portal vein, hepatic vein based on living donor candidate’s angiographic computed tomography data in living donor liver transplantation.Materials and Methods: First, we obtained angiographic computed tomography data with a stereolithography extension of the living donor candidate. Then, we made this data suitable for the 3 dimensional printer by using a special software. We used a J750 Stratasys 3 dimensional printer to create the model.Results: In the three-dimensional model, macroscopic liver structure and vascular structures were obtained as planned hepatic artery, portal vein, hepatic vein and in accordance with angiographic computed tomography data.Conclusion: Before living donor liver transplantation, models obtained from 3 dimensional printers can be used to evaluate the anatomic structure of the donor candidate’s liver. Similarly, prior to complicated liver resections, this model can provide surgeons with a different perspective for more effective preoperative planning and assessment for safer surgery
