RESUMO
Objective To explore the value of medical three-dimensional visualization technology in preoperative precise assessment for hepatocellular carcinoma (HCC).Methods The clinical data of 24 HCC patients were analyzed retrospectively from Jan 2015 to Dec 2016 in our department.Thin-layer 320-slice CT scaning was performed and data stored in the form of DICOM.Three dimensional reconstruction and simulated hepatectomy were conducted,and correlation test analysis was performed.Results The volume of simulated resected liver was (565 ± 296)ml,while the actual liver resection volume was(523 ± 252)ml.There was no significant difference between the predicted and the actual values (t =1.734,P ＞ 0.05).The actual liver resection volume was positively correlated with the predicted liver resection volume (r =0.920,P ＜ 0.05).The stimulated resection margin was (1.2 ± 0.6)cm,while the actual resected tumor margin was (1.0 ± 0.5) cm.There was no significant difference between the predicted and the actual values (t =1.853,P ＞0.05).The actual margin was positively correlated with the predicted one (r =0.956,P ＜ 0.05).Conclusion The three-dimensional visualization technology has a certain degree of clinical value in the preoperative evaluation of HCC.
