Living donor liver transplantation in situs inversus totalis with a patient‐specific three‐dimensional printed liver model

We utilized patient‐specific 3D liver models based on preoperative computed tomography images as intraoperative navigation and describe our experience. A 1‐year and 10‐month‐old girl with situs inversus totalis underwent living donor liver transplantation for biliary atresia. Information on the hepa...

Description
Summary:We utilized patient‐specific 3D liver models based on preoperative computed tomography images as intraoperative navigation and describe our experience. A 1‐year and 10‐month‐old girl with situs inversus totalis underwent living donor liver transplantation for biliary atresia. Information on the hepatic artery, portal vein, inferior vena cava, and liver parenchyma was extracted and segmented from computed tomography images using liver analysis software. Laser lithography produced each 3D part of the liver from these data. The 3D models of each part of the liver were molded from polyurethane resin using different colors for each part and combined together, resulting in a patient‐specific liver model. The industrial computed tomography scan of the patient‐specific 3D liver model revealed that the gaps between the liver model and the original data were
