Noninvasive ultrasound technique for assessment of liver fibrosis and cardiac function in Fontan-associated liver disease: diagnosis based on elastography and hepatic vein waveform type

Hepatic and portal vein Doppler ultrasounds in assessing liver inflammation and fibrosis in chronic HBV infection with a normal ALT level

Aims

To discuss the clinical value of hepatic and portal vein Doppler ultrasounds in assessing liver inflammation and fibrosis in patients with chronic hepatitis B virus (HBV) infection, and a normal alanine transaminase (ALT) level.

Methods

94 patients with chronic HBV infections who had undergone ultrasound-guided liver biopsies were enrolled and grouped by the liver tissue pathological results. Analyzed the differences and correlation between parameters of the hepatic and portal vein Doppler ultrasounds are discussed across different degrees of liver inflammation and fibrosis.

Results

There were 27 patients with no significant liver damage and 67 patients with significant liver damage, there were significant differences in the parameters of the hepatic and portal vein Doppler ultrasounds between them (p < 0.05). As liver inflammation was aggravated, the inner diameter of the portal vein increased, and the blood flow velocities of the portal and superior mesenteric veins decreased (p < 0.05). When liver fibrosis became more severe, the inner diameter of the portal vein increased, while the blood flow velocities of the portal, superior mesenteric, and splenic veins decreased, and the Doppler waveforms of hepatic veins became unidirectional or flat (p < 0.05). The receiver operating characteristic (ROC) curve showed the assessment efficacy of hepatic and portal vein Doppler ultrasounds was superior to abdominal Doppler ultrasound alone in assessing liver fibrosis, and the combination of the two examination techniques outperformed any technique used alone.

Conclusion

The hepatic and portal vein Doppler ultrasounds have important clinical value for assessing liver fibrosis in patients with chronic HBV infection, to aid improve the diagnosis of liver fibrosis.

Robust Effect of Hepatic Arterial Infusion Chemotherapy and Radiation Therapy on Hepatocellular Carcinoma Arising from Fontan-associated Liver Disease

Fontan-associated liver disease (FALD) caused by long-term systemic venous congestion following the Fontan procedure may eventually lead to hepatocellular carcinoma (HCC). Treatment strategies for HCC due to FALD (FALD-HCC) remain unclear. We herein report a 35-year-old man with FALD-HCC that was well controlled by 3 cycles of continuous infusion of 5-fluorouracil and low-dose cisplatin (low-dose FP therapy) combined with 60 Gy of radiation therapy. However, the patient ultimately died of extrahepatic metastases. A pathological autopsy revealed more than 90% necrosis in the primary HCC lesion. This case suggests that low-dose FP therapy might be effective in FALD-HCC.
