摘要
目的评价超声在原发性肝癌患者伴发肝动静脉瘘(HAVF)的应用价值。方法超声观察83例临床确诊原发性肝癌患者门静脉、肝动脉、肝静脉、肝周以及肿瘤周围和内部血管走行及血流状态,对疑为HAVF的病例与数字减影血管造影(DSA)结果对照,确定HAVF存在的真实性。结果本组83例原发性肝癌患者超声检出HAVF 25例,准确率88%,假阳性率12%。结论彩色多普勒超声可作为检测原发性肝癌HAVF的有效方法。
Objective To investigate the ultrasonographic characteristics and hemodynamics of hepatocellular carcinoma-associated hepatic arteriovenous fistula(HAVF) and evaluate the capability of two dimensional and doppler ultrasonography in detection of HAVF.Methods Eighty-three patients diagnosed as hepatocellular carcinoma were enrolled in thes study.The portal and hepatic veins,hepatic arteries and vessels around and inside the tumor were detected by color doppler.The results of HAVF patients from doppler were compared with those from digital substraction angiography(DSA).Results Twenty-five HAVF were detected by doppler.The accuracy rate was 88%,false-positive rate was 8%.Conclusion Color doppler could be used for diagnosing HAVF.
