Abstract
Objective To study the blood perfusion characteristics of different kinds of liver cancer lesions and portal vein tumor thrombosis(PVTT) by color Doppler ultrasound(CDUS) and contrast-enhanced ultrasound(CEUS).Methods The blood perfusion characteristics and hemodynamics change of 437 leisons in 369 patients with liver cancer and included PVTT comfirmed by clinical data were analyzed by CEUS and CDUS.Results The blood perfusion characteristics of liver cancer lesions were varied: ①72.8%(318/437) were mainly hepatic artery type;16.7%(73/437) were hepatic artery and portal vein blood supply type;8.2%(36/437) were hepatic artery and portal vein blood supply combined arteriovenous fistula type;2.3%(10/437) were mainly portal vein type.②The blood perfusion characteristics of PVTT were hepatic artery or double blood supply type.③The initial enhanced shape of CEUS was closely correlated with vascular distribution of tumor.Conclusion CEUS can identify the blood perfusion characteristics of liver cancer and PVTT,which be valuable to diagnosis and treatment of liver cancer.
