摘要
目的:研究原发性肝癌(PLC)在肝静脉、下腔静脉、右心房内生长的影像学诊断。方法:采用两维超声、彩色多普勒超声、CT、MRI、血管造影,重点观察PLC患者的肝静脉、下腔静脉与右心房内瘤栓。结果:20例PLC患者中,弥漫型1例,结节、肿块型19例,主瘤灶最大径7～18(12.3±3.1)cm,肝静脉瘤栓19例,下腔静脉瘤栓19例,右心房瘤栓11例,呈肝静脉-下腔静脉-右心房瘤栓11例、肝静脉-下腔静脉瘤栓7例、下腔静脉-右心房瘤栓与肝静脉瘤栓各1例。结论:对于PLC在肝静脉、下腔静脉与右心房内生长,及时而正确的诊断依赖于影像学检查。瘤栓多为肝动脉源性供血,血管造影对诊断有重要意义。
Objective To study the image diagnosis of the extension of hepatic vein （HV）,inferior vena cava （IVC） and right atrium（RA） primary liver carcinoma（PLC）. Methods Twenty PLC cases in whose HV,IVC and RA there were tumor extension were detected by two-dimensional ultrasound,CT,MRI and angiography. Results The tumor embolus（TE） manifested as HVTE-IVCTE-RATE in 11 cases, HVTE-IVCTE in 7 cases, IVCTE-HVTE and HVTE in 1 case, respectively. Conclusions The right and duly diagnosis of the tumor embolus grown into HV,IVC and RA in the PLC patients depended upon imaging examination. Angiography maybe plays an important role in the tumor embelus for its blood supply coming from hepatic artery.
