目的分析探讨肝血管瘤的彩超表现,提高肝血管瘤的临床诊断率。方法回顾性分析本院64例肝血管瘤患者的临床资料,用彩色多普勒超声进行检查并详细记录,分析肝血管瘤切面的超声特征性表现、血管形态表现、血流动力学参数等。结果 64例肝血管瘤经手术或穿刺活检病理证实,彩超诊断58例为肝血管瘤(确诊率90.6%)、6例诊断为原发性肝癌(误诊率9.4%);本组64例中有9例为低回声型(占14.1%),50例为高回声型(占78.1%),5例混合回声型(占7.8%);大部分小于3cm的肿块内部及周边未发现明显的血流信号,少部分小肝血管瘤内部可有斑点状红色或蓝色血流信号,阻力指数约0.50～0.55。结论彩超诊断肝血管瘤具有操作简便、耗时短、干扰小的优点,结合CT扫描、MRI等影像学手段可提高肝血管瘤的诊断率。
Objective To analyze the color Doppler echocardiography of hepatic hemangiomas and to improve the clinical diagnosis rate of hepatic hemangiomas. Methods The clinical data of 64 patients with hepatic hemangioma in our hospital were retrospectively analyzed. The color Doppler ultrasound was used to examine and record the characteristics of the hepatic hemangioma in detail. The morphological features of blood vessels and hemodynamic parameters were analyzed. Results 64 cases of hepatic hemangioma confirmed by surgery or biopsy, color Doppler ultrasound diagnosis of 58 cases of hemangiomas (diagnosis rate of 90.6%), 6 cases of diagnosis of primary liver cancer (misdiagnosis rate of 9.4%); 64 cases in this group 9 cases were hypoechoic (14.1%), 50 cases were hyperechoic (78.1%) and 5 cases were mixed echoes (7.8%). In most cases less than 3 cm, no obvious blood flow was found in and around the tumor Signal, a small part of small hepatic hemangioma may have speckled red or blue blood flow signal, resistance index of about 0.50 ~ 0.55. Conclusion The diagnosis of hepatic hemangiomas by color Doppler ultrasonography has the advantages of simple operation, short time-consuming and less interference. Combined with CT and MRI, hemangiomas can be diagnosed.
