【摘要】 目的　探讨小肝癌的滋养血管血供特征及其诊断价值。方法　对 3 1例小肝癌进行了彩色多普勒能量图 (CDE)检查 ,并与数字减影血管造影 (DSA)对照。结果　小肝癌动脉肿瘤输入血管检出率90 .3 % ,最大血流速度 (Vmax) (4 5 .3 5± 2 2 .43 )cm/s ,阻力指数 (RI) 0 .69± 0 .13 ;门静脉肿瘤输入血管检出率41.9% ;此外CDE可显示 15例 (4 8.4% )小肝癌有肿瘤输出静脉血管 ,其中 13例 (4 1.9% )为门静脉肿瘤输出血管 ,2例 (6.5 % )为肝静脉肿瘤输出血管。结论　CDE对小肝癌的诊断具有重要意义 ,肝癌肿瘤输出静脉血管可能是肝癌易发生门静脉癌栓及肝内转移的主要因素。更多还原

【Abstract】 Objective To evaluate the patterns of tumor feeding vessels and their value in the diagnosis of small hepatocellular carcinoma(SHCC) by color Doppler energy(CDE).Methods Thirty-one cases with SHCC were investigated by CDE and correlated with findings at digital subtraction angiography(DSA). Results The detecting rate of arterial flow afferent tumor vessel in SHCCs was 90.3 %,the mean maximum blood flow velocity(Vmax) and the resistive index (RI) were ( 45.35 ± 22.43 )cm/s and 0.69 ± 0.13 ,respectively. The detected rate of portal flow afferent tumor vessel in SHCCs was 41.9 %. In addition, PDS revealed a constant flow efferent tumor vessel ( 48.4 %) continuing to a portal branch in 13( 41.9 %) of the 31 SHCCs, to a hepatic vein in 2( 6.5 %) of the 31 SHCCs. Conclusions CDE is of great value in the diagnosis of SHCC. In addition,efferent tumor vessel might be the main factor of portal tumor thrombi and hepatic metastases.更多还原
