Application Value Of There-dimensional Computerized Tomography Reconstruction And Hepatic Volume Measurement In Giant And Complicated Liver Tumors In Children

Objective To assess the role of three-dimensional reconstruction with spiral CT and hepatic volume measurement for the guidance of operation in giant and complicated liver tumors in children.Methods Clinical data of 25 cases with giant and complicated liver tumors during the last 8 years were retrospectively analyzed.All of them were examined by the there-dimensional reconstruction using 64 slice spiral CT.The hepatic artery,portal vein and hepatic vein images were reconstructed and total liver volume and resected liver volume were measured.The postoperatve hepatic volume with hepatic volume standardized by body surface was acquired.Results There-dimensional computerized tomography reconstructionin could render anatomic details of hepatic artery,portal vein and hepatic vein from varied points of view.And relationship between the adjacent vessels and tumors were clearly demonstrated by the three-dimensional computed tomography reconstruction in the 25 patients.21 patients accepted operations,4 patients did not perform operations.During the 21 patients,the average postoperative residual hepatic volume was 182.55cm~3.The minimal postoperative residual hepatic volume was 62.26cm~3.The average relative ratio(the ratio between postoperative and standardized hepatic volume) was 44.69%.The minimal relative ratio was 20.16%.Conclusions There-dimensional computerized tomography reconstructional imaging can provide high quality images of the tumors and clearly demonstrate the relationship between tumor and the adjacent blood vessels.There-dimensional computerized tomography reconstructional imaging and the ratio between postoperative and standardized hepatic volume would play an important role in the guidance for resection of giant and complicated liver tumors in children.
