| Objective：To explore the clinical application value of the three–dimensionalreconstruction system of liver and virtual surgery planning in the treatment of thehepatic alveolar echinococcosis.Methods：(1) the object of study: select the qinghaiuniversity affiliated hospital during2012.102014.03hospitalized patients21cases;(2)collect three periods of patients with liver dynamic thin layer CT scan images, importdigital liver liver in DICOM format three–dimensional reconstruction software(EDDA company authorized by the United States), three-dimensional imagingoperation simulation, calculation parameters, the design scheme of virtual surgerysurgical removal of the lesions, weigh the actual resection of liver tissue volume, thestatistical analysis, draw the conclusion.Results：Virtual surgery in patients with21patients underwent resection of the hepatic design, measured for resection of livervolume (47.75-2191.78) ml, the average（761.94±505.77）ml. To remove the livervolume accounts for liver volume (1.20-52.54)%, the average（27.70±16.68）%.21patients with routine liver resection, intraoperative actual resection of liver volume(105-2350) ml, the average (756.19±501.78) ml;Surgical removal of the liver volumeaccounts for liver volume (6.67-64.53)%, the average（38.95±16.99）%. The datameasured and virtual surgery to remove data are basically identical.Conclusion：Thethree–dimensional reconstruction and the virtual surgery planning system of liver... |
