“…They found that echo-Doppler USG was highly sensitive for the evaluation of postprandial hyperemia [4] . Additionally, several studies have been done to investigate the effects of different drugs on postprandial hyperemia by using echo-Doppler USG [5][6][7][8] . However, to the best of our knowledge, there is no study which compares the hepatic venous catheterization with echo-Doppler USG in the assessment of PPH in patients www.wjgnet.com with cirrhosis.…”

AIM:To assess the role of echo-Doppler ultrasonography in postprandial hyperemia in cirrhotic patients by comparing the results with the hepatic vein catheterization technique. METHODS:Patients with cirrhosis, admitted to the portal hemodynamic laboratory were included into the study. After an overnight fast, echo-Doppler ultrasonography (basal and 30 min after a standard meal) and hemodynamic studies by hepatic vein catheterization (basal, 15 min and 30 min after a standard meal) were performed. Ensure Plus (Abbot Laboratories, North Chicago, IL) was used as the standard liquid meal. Correlation analysis of the echoDoppler and hepatic vein catheterization measurements were done for the basal and postprandial periods. RESULTS: Eleven patients with cirrhosis (5 Child A, 4Child B, 2 Child C) were enrolled into the study. After the standard meal, 8 of the 11 patients showed postprandial hyperemia with increase in portal blood flow, portal blood velocity and hepatic venous pressure gradient. Hepatic venous pressure gradient in the postprandial period correlated positively with postprandial portal blood velocity (r = 0.8, P < 0.05) and correlated inversely with postprandial superior mesenteric artery pulsatility index (r = -1, P < 0.01). CONCLUSION:Po s t p ra n d i a l h y p e r e m i a c a n b e efficiently measured by echo-Doppler ultrasonography and the results are comparable to those obtained with the hemodynamic studies.

“…PV flow (about 15% of the cardiac output) increases significantly following food ingestion and decreases during physical exercise or after the release of stress hormones (104). These physiological events are of relatively short duration, but patients with PH develop more permanent changes (7,69,94). Persistent pressure elevation results in development of numerous collaterals draining blood from the PV to the systemic veins.…”

Rapid development of diagnostic radiological methods during recent decades has been followed by development of new interventional procedures involving portal circulation. The majority of these interventions were developed for treatment of patients with symptoms secondary to portal hypertension (PH). Interventions involving portal vein circulation have an established position in the treatment of PH and other diseases, and further development of these methods can be expected.

“…For example, in partial hepatectomy, in order to accurately control the resection ratio to ensure that the remaining liver after the operation can maintain the normal metabolic activities of the human body, it is necessary to study the relationship among the liver resection ratio, the blood pressure and blood flow of the blood vessels in the liver [2] . In addition, the hemodynamic changes of the liver blood supply relate to the development and deterioration of several liver diseases [5]. Therefore, the hemodynamics of the liver has always been a concern of scientists, physicians and surgeons.…”

The liver has a unique blood supply system and plays an important role in the human blood circulatory system. Thus, hemodynamic problems related to the liver serve as an important part in clinical diagnosis and treatment. Although estimating parameters in these hemodynamic models is essential to the study of liver models, due to the limitations of medical measurement methods and constraints of ethics on clinical studies, it is impossible to directly measure the parameters of blood vessels in livers. Furthermore, as an important part of the systemic blood circulation, livers' studies are supposed to be in conjunction with other blood vessels. In this article, we present an innovative method to fix parameters of an individual liver in a human blood circulation using noninvasive clinical measurements. The method consists of a 1-D blood flow model of human arteries and veins, a 0-D model reflecting the peripheral resistance of capillaries and a lumped parameter circuit model for human livers. We apply the finite element method in fluid mechanics of these models to a numerical study, based on non-invasive blood related measures of 33 individuals. The estimated results of human blood vessel characteristic and liver model parameters are verified from the perspective of Stroke Value Variation, which shows the effectiveness of our estimation method.
