Sonographic Evaluation of Portal Vein Thrombosis in Hepatocellular Carcinoma and Liver Metastasis
肝細胞癌及肝轉移癌門靜脈栓塞之超音波檢查
摘要
Sonography was performed in 68 cases of liver tumors to evaluate the incidence of portal vein thrombosis (PVT). Thirty four of these cases had also received angiography. Thirty one of them were performed adequately and were used for evaluating the accuracy of sonographic examinations. There was a good correlation (93.5%, 29/31) between the two examinations. Pvt was discovered in 34(72.3%) of 47 cases of hepatocellular carcinoma (HCC) and in 1 (4.8%) of 21 cases of liver metastasis by sonography. The incidence of PVT is much higher in the HCC group than in the liver metastasis group (p＜0.001). Because only 1 of 35 (2.8%) cases with PV thrombosis was related to liver metastasis, the presence of PVT in liver tumors is highly diagnostic for HCC. Its sensitivity, specificity, positive predictive value, negative predictive value and accuracy, are 72.3%,95.2%,97.2%,60.6% and 79.4% respectively.
