UNASSIGNED: A 3D model of the donor liver with hepatic venous structures printed within it was prepared using image acquisition data. The model was used for a simulated cut preoperatively, to mimic the donor hepatectomy based on the venous structures seen through the transparent material used for making the liver model. The volume of the graft measured by volume displacement in the actual surgery was compared with the volume of the model after the simulated cut.
UNASSIGNED: The calculated volume of the graft was 359 ml as per the preoperative simulation, and the observed weight/volume was 380 gm/310 ml.
UNASSIGNED: Three-dimensional printing of liver models using imaging data can help predict the actual size of the graft after donor hepatectomy, in patients undergoing living donor liver transplantation.
■使用图像采集数据制备其内印有肝静脉结构的供体肝脏的3D模型。该模型用于术前模拟切口,根据通过用于制作肝脏模型的透明材料看到的静脉结构来模拟供体肝切除术。将实际手术中通过体积位移测量的移植物体积与模拟切割后的模型体积进行比较。
■根据术前模拟计算的移植物体积为359ml,观察到的重量/体积为380gm/310ml。
■使用成像数据对肝脏模型进行三维打印可以帮助预测供体肝切除术后移植物的实际大小,在接受活体肝移植的患者中。
