摘      要：AIM:To clarify which method has accuracy:2nd gen-eration contrast-enhanced ultrasound or biopsy of portal vein thrombus in the differential diagnosis of portal vein ***:One hundred and eighty-six patients with hepatocellular carcinoma and portal vein thrombosis underwent in blinded fashion a 2nd generation contrast-enhanced ultrasound and biopsy of portal vein thrombus;both results were examined on the basis of the follow-up of patients compared to ***:One hundred and eight patients completed the *** thrombosis on 2nd generation contrast-enhanced ultrasound was characterised by progressive hypoenhancing of the thrombus;in malignant portal vein thrombosis there was a precocious homo-geneous enhancement of the *** follow-up there were 50 of 108 patients with benign thrombosis:all were correctly diagnosed by both *** were 58 of 108 patients with malignant thrombosis:amongst these,52 were correctly diagnosed by both methods,the remainder did not present malignant cells on portal vein thrombus biopsy and showed on 2nd generation contrast-enhanced ultrasound an inho-mogeneous enhancement pattern.A new biopsy during the follow-up,guided to the area of thrombus that showed up on 2nd generation contrast-enhanced ultra-sound,demonstrated an enhancing pattern indicating malignant ***:In patients with hepatocellular carcinoma complicated by portal vein thrombosis,2nd generation contrast-enhanced ultrasound of portal vein thrombus is very useful in assessing the benign or malignant nature of the *** biopsy of thrombus is usually accurate but presents some sampling errors,so,when pathological results are required,2nd generation contrast-enhanced ultrasound could guide the sampling needle to the correct area of the thrombus.
