目的探讨肝癌复发灶的超声表现。方法回顾性分析33例肝癌术后肝内复发患者B超表现及临床资料。结果21例规则随访组单个复发灶最大直径平均1.95cm,其中16例表现为低回声;12例不规则随访组复发灶最大直径平均4.81cm,其中8例为低回声结节。全组19例行彩色多普勒血流显像(CDFI)检查者,团块内探及彩色血流信号15例,10例频谱多普勒测及动脉搏动型曲线,平均RI值为0.73。结论超声对肝癌术后复发的诊断有重要作用。
Objective To investigate the ultrasound manifestations of recurrence of liver cancer. Methods We retrospectively analyzed the B ultrasound findings and clinical data of 33 patients with hepatocellular carcinoma after intrahepatic recurrence. Results The maximum diameter of single recurrence in the 21 follow-up groups was 1.95 cm on average, of which 16 cases showed hypoechoicity. The average diameter of recurrence in the 12 cases of irregular follow-up group was 4.81 cm, of which 8 cases were hypoechoic nodules. All 19 patients underwent color Doppler flow imaging (CDFI) examination, intracapsular exploration and color flow signal in 15 cases, 10 cases of spectrum Doppler measurement and arterial pulse curve, the average RI value was 0.73. Conclusion Ultrasound has an important role in the diagnosis of recurrence of liver cancer.
