Changes in hepatic hemodynamics due to primary liver tumours
1Department of Surgery, Semmelweis University of Medicine & St. John Hospital Budapest, Hungary.
Summary
Hepatocellular carcinoma alters liver blood flow, increasing hepatic artery flow and decreasing portal vein flow. This ratio change may offer diagnostic insights using Doppler ultrasound.
Area of Science:
- Hepatology
- Vascular Surgery
- Diagnostic Imaging
Background:
- Afferent circulation data in hepatocellular carcinoma (HCC) patients is debated.
- Understanding liver blood flow dynamics is crucial for HCC management.
Purpose of the Study:
- To quantify hepatic arterial and portal venous flow in HCC patients.
- To investigate the ratio of hepatic arterial to portal venous flow.
- To assess the impact of resection on liver hemodynamics.
Main Methods:
- Intraoperative transit time ultrasonic volume flowmetry was used.
- Hepatic arterial and portal venous blood flow were measured.
- Flow measurements were compared between HCC patients and controls.
Main Results:
- Hepatic artery flow increased significantly (p < 0.01) in HCC patients.
- Portal venous flow decreased significantly (p < 0.01) in HCC patients.
- The ratio of hepatic arterial to portal venous flow doubled in HCC patients, remaining unchanged post-resection.
Conclusions:
- HCC significantly alters liver afferent circulation patterns.
- The elevated hepatic arterial to portal venous flow ratio in HCC may be a valuable diagnostic marker.
- Doppler ultrasound assessment of this ratio could provide diagnostic information.
