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 evaluate the value of ultrasound in the treatment of hepatic arteriovenous fistula (HAVF) in patients with primary liver cancer. Methods The portal vein, hepatic artery, hepatic vein, peripheral and internal blood vessels in 83 patients with primary hepatocellular carcinoma were observed by ultrasonography. The pathological changes and blood flow status of the patients with suspected HAVF and digital subtraction angiography (DSA) Control, to determine the existence of HAVF authenticity. Results Totally 83 HAVF patients were detected by ultrasonography in 25 cases of HCC in this group, with an accuracy of 88% and a false positive rate of 12%. Conclusion Color Doppler ultrasound can be used as an effective method to detect HAVF in primary liver cancer.
