基于计算机辅助手术系统的儿童肝脏肿瘤与门静脉关系的影像学分析
Digital imaging analysis of relationship between liver tumors and portal veins based on computer-assis- ted surgery system
摘要
Abstract
Objective To analyze the relationship between liver tumors and portal veins and explore the clinical value of Hisense computer-assisted surgery system (CAS) during pediatric liver surgery.Methods The clinical data of 56 cases with liver tumors from January 2015 to December 2016 was analyzed.There were 30 boys and 16 girls with an age range of 1 month to 12 years.There were hepatoblastoma (n = 42),hepato-cellular carcinoma (n = 5),hemangioendothelioma (n = 5),mesenchymalhamartoma (n = 1),undifferentiat-ed sarcoma (n = 1) and hepatic metastases of teratoma (n = 2).Hisense CAS was used for three-dimensional reconstructing based upon thin-layer computed tomography (CT).Contrast operation planning was based on common CT imaging along with three-dimensional reconstructing results.Residual liver volume was measured after virtual tumor resection.Results In left lobe of liver (n = 7),tumors invaded left portal vein trunk (secondary branches of portal vein) (n = 6) and the third branches of portal vein (n = 1); in right lobe of liv-er (n = 40),tumors involved the right portal vein trunk (secondary branches of portal vein) (n = 33) and the third or forth branches of portal vein (n = 7); in medial lobe of liver (n = 8),tumors infiltrated right or left portal vein trunk (secondary branches of portal vein) (n = 5) and right or left portal vein trunk (secondary branches of portal vein) (n = 3); diffuse liver tumor (n = 1).Six cases had no chance of one-stage surgery.Conclusion Hisense CAS can delineate distinctly vascular system and adjacent relationship of tumor so as to improve the accuracy and safety during pediatric liver surgery.关键词
