Application of 3D reconstruction for surgical treatment of hepatic alveolar echinococcosis

Figure 1 3D reconstruction and anatomical analysis. A: Diagnosis of giant hepatic alveolar echinococcosis (HAE) by computed tomography; B: 3D reconstruction model of a liver showing the lesion (red arrow) and normal liver (black arrow); C: Real-time correction between the 3D model and 2D image; D: 3D reconstruction model of a liver showing the lesion as well as intrahepatic biliary and vascular networks. 1: Lesion; 2: Right kidney; 3: Hepatic vein (deep blue); 4: Portal vein (light blue); 5: Abdominal aorta (red).

Figure 2 Liver. A: 3D model of a liver showing virtual surgery and the remnant liver (red arrow); B: Remnant liver volume calculated in virtual surgery (1090 cm³); C: Actual surgery showing the lesion (the lesion and normal liver are marked by a white and a black arrow, respectively); D: Remnant liver in actual surgery (1145 g).
