The effects of vaso-active agents on hepatic function and splanchnic oxygenation were studied in 17 patients with cirrhosis and portal hypertension. Eight patients received vasopressin (0.3 iu/min) and nine patients received nitroglycerin (50 micrograms/min). Both drugs caused a significant reduction in the portal venous pressure gradient. Vasopressin infusion significantly decreased intrinsic clearance of indocyanine green (-23%, P less than 0.01). This may be due to a decreased hepatic perfusion (-28%, P less than 0.01) and portal venous oxygenation (-15% in portal venous oxygen tension, P less than 0.05). In contrast, no changes in hepatic perfusion and portal venous oxygenation were observed after nitroglycerin infusion. Nitroglycerin did not decrease intrinsic clearance of indocyanine green. These results suggest that vasodilators, rather than vasoconstrictors, might be welcome in the treatment of patients with cirrhosis and portal hypertension. 相似文献

Although hepatic blood flow (HBF) has been measured in patients with liver disease for many years, the results of these studies have not provided clear information concerning the usefulness of this measurement. Hepatic blood flow was measured in 392 patients with either cirrhosis (n= 356) or hepatic fibrosis (n= 36). The control group included 59 subjects with normal liver architecture. Hepatic clearance of indocyanine green (ICG) was markedly reduced in patients with cirrhosis and hepatic fibrosis compared with controls (182±5, 276±22 and 421±25 mL/min, respectively). In patients with cirrhosis, ICG clearance and extraction were significantly correlated, but were not correlated to HBF. Although HBF did not differ between patients with cirrhosis and controls (1.26±0.04 vs 1.35±0.07 L/min, respectively), patients with hepatic fibrosis had lower HBF (1.04±0.07 L/min; P< 0.05). In patients with cirrhosis, no correlation was observed between HBF and cardiac output, mean arterial pressure, azygos blood flow, the hepatic venous pressure gradient or Pugh's score. However, a significant difference in HBF was observed in patients with and without hepatic encephalopathy (1.00±0.09 vs 1.28±0.03 L/min, respectively; P<0.05). In conclusion, the present study shows that, in patients with cirrhosis, HBF is normal and is not related to other haemodynamic values or liver tests. These results discourage the measurement of HBF in the evaluation of patients with cirrhosis. 相似文献

Effects of nifedipine on hepatic venous pressure gradient and portal vein blood flow in patients with cirrhosis 总被引:1,自引:0,他引:1
KAZUHIRO OTA HIROSHI SHIJO HIROSHI KOKAWA KATSUHIKO KUBARA TETSUHIRO KIM NOBUO AKIYOSHI MASANORI YOKOYAMA MAKOTO OKUMURA 《Journal of gastroenterology and hepatology》1995,10(2):198-204
Abstract We investigated the effects of nifedipine on splanchnic haemodynamics in 13 patients with cirrhosis and portal hypertension, and in 10 control subjects using hepatic venous catheterization and pulsed Doppler ultrasound. There were no significant changes in systemic or splanchnic haemodynamics in control patients. In contrast, systemic vascodilatation, evidenced by significant decreases in mean arterial pressure and systemic vascular resistance, was observed in patients 20 min after sublingual application of 10 mg nifedipine. Moreover, hepatic venous pressure gradient and portal vein blood flow significantly increased after nifedipine administration. There was a significant correlation between the percentage increases in portal vein blood flow and in hepatic venous pressure gradient. However, no correlation was found between the percentage change in cardiac output and that in portal vein blood flow. Thus the increase in portal vein blood flow appears to be related to splanchnic arterial vasodilatation by nifedipine. Consequently, nifedipine has deleterious effects on portal haemodynamics in patients with cirrhosis. As nifedipine may potentially increase the risk of variceal haemorrhage in patients with less advanced varices, this drug should be used with caution in patients with chronic liver disease. 相似文献

Triglycyl-lysin-vasopressin is a long-acting vasopressin derivative which is under consideration for the treatment of acute variceal bleeding in cirrhosis. However, its splanchnic hemodynamic effects have not been investigated thoroughly. In 11 patients with alcoholic cirrhosis, systemic and splanchnic hemodynamics were evaluated before and 20–40 min after intravenous administration of 2 mg triglycyl-lysin-vasopressin. Following the drug administration, heart rate decreased by 10% and cardiac index by 22% on the average, respectively; mean arterial pressure increased by 14% and systemic vascular resistence index by 48%. Hepatic venous pressure gradient showed a marked and persistent fall, averaging 31%. Hepatic and splenic blood flow decreased by 31% and 56%, respectively. A significant correlation was found between the decrease in hepatic venous pressure gradient and in splenic blood flow. By contrast, the decrease in the hepatic venous pressure gradient was not significantly correlated to the decrease in hepatic blood flow or in cardiac index. We conclude that in patients with alcoholic cirrhosis, triglycyl-lysin-vasopressin decreases portal pressure as well as hepatic and splenic blood flows. The decrease in portal pressure was due to the decrease in splanchnic blood inflow and not to the decrease in cardiac index.This work was supported in part by a grant from the Italian Ministry of Education (National Project Liver Cirrhosis). 相似文献

Comparison of Doppler ultrasonography and the hepatic venous pressure gradient in assessing portal hypertension in liver cirrhosis 总被引:1,自引:0,他引:1

BACKGROUND AND AIM: This prospective study aimed to determine whether Doppler ultrasonography can represent the hepatic venous pressure gradient (HVPG) as an assessment of the severity of portal hypertension and the response to terlipressin, which reduces the portal pressure in liver cirrhosis. METHODS: The HVPG and the Doppler ultrasonographic parameters, such as the portal venous velocity and the splenic venous velocity, the pulsatility and the resistive index of the hepatic, splenic and renal arteries were measured in 138 patients with liver cirrhosis. The changes in the HVPG and the portal venous velocity after administering terlipressin were evaluated in 43 of the 138 patients. The patients who showed a reduction in the HVPG of more than 20% of the baseline were defined as responders to terlipressin. RESULTS: None of the Doppler ultrasonographic parameters correlated with the HVPG. Both the HVPG (28.0 +/- 19.8%) and the portal venous velocity (29.7 +/- 13.2%) showed a significant reduction after terlipressin administration. However, the portal venous velocity decreased significantly, not only in the responders (31.0 +/- 12.0%) but also in the non-responders (25.2 +/- 16.4%). CONCLUSIONS: Doppler ultrasonography does not represent the HVPG, and is therefore not suitable for replacing HVPG as a means of assessing the severity of portal hypertension and the response to drugs which reduce the portal pressure in liver cirrhosis. 相似文献

Background/Aims: Endocannabinoids include anandamide (AEA) and 2‐arachidonoylglycerol (2‐AG). Endocannabinoid‐related molecules like oleoyl‐ethanolamine (OEA) and palmitoyl‐ethanolamine (PEA) have also been identified. AEA contributes to the pathogenesis of cardiovascular alterations in experimental cirrhosis, but data on the endocannabinoid system in human cirrhosis are lacking. Thus, we aimed to assess whether circulating and hepatic endocannabinoids are upregulated in cirrhotic patients and whether their levels correlate with systemic haemodynamics and liver function. Methods: The endocannabinoid levels were measured in peripheral and hepatic veins and liver tissue by isotope‐dilution liquid chromatography‐atmospheric pressure chemical ionization‐mass spectrometry. Systemic haemodynamics were assessed by the transthoracic electrical bioimpedance technique. Portal pressure was evaluated by hepatic venous pressure gradient. Results: Circulating AEA and, to a greater extent, PEA and OEA were significantly higher in cirrhotic patients than in controls. PEA and OEA were also increased in the cirrhotic liver tissue. AEA, OEA and PEA levels were significantly higher in peripheral than in the hepatic veins of cirrhotic patients, while the opposite occurred for 2‐AG. Finally, circulating AEA, OEA and PEA correlated with parameters of liver function, such as serum bilirubin and international normalized ratio. No correlations were found with systemic haemodynamics. Conclusions: The endocannabinoid system is upregulated in human cirrhosis. Peripheral AEA is increased in patients with a high model of end‐stage liver disease score and may reflect the extent of liver dysfunction. In contrast, the 2‐AG levels, the other major endocannabinoid, are not affected by cirrhosis. The upregulation of the endocannabinoid‐related molecules, OEA and PEA, is even greater than that of AEA, prompting pharmacological studies on these compounds. 相似文献

To examine the degree of influence of the hepatic artery on microcirculation in the liver, microscopic observation of blood flow in the hepatic minute blood vessels and the sinusoids and pressure measurements at key points in hepatic vascular pathways in vivo were performed before and after hepatic artery ligation in normal and cirrhotic rats. In normal rats, portal vein pressure (109 mmH2O) fell 10 mmH2O after hepatic artery ligation, but the pressures of the terminal portal venule, the terminal hepatic venule and the inferior vena cava did not change. In cirrhotic rats, portal vein pressure (206 mmH2O) and terminal portal venule pressure (106 mmH2O) fell 23 and 10 mmH2O after hepatic artery ligation respectively: the pressures in the terminal hepatic venule and the inferior vena cava did not change. These results suggests that the pressure transmitted from the hepatic artery was mostly supplied to the intrahepatic portal vein in normal rats and both to the intrahepatic portal vein and to the sinusoids in cirrhotic rats. In both normal and cirrhotic rats, however, the pressure transmitted from the hepatic artery was about 10 per cent of the initial portal vein pressure, and the blood flow in minute vessels and sinusoids did not change after hepatic artery ligation. Accordingly, it is believed that the hepatic artery plays only a small role in the haemodynamics of the liver in both normal and cirrhotic rats, irrespective of the distribution and manner of the hepatic arterial termination. 相似文献

ABSTRACT— We examined the oxygen content in the hepatic arterial, hepatic venous and portal venous blood to evaluate the oxygen supply to the liver and hepatic oxygen extraction in cirrhosis. The arterial-portal venous difference of the oxygen content was within the normal range in cirrhosis patients, although the oxygen content of the hepatic artery and portal vein was lower than in the control patients. The hepatic venous oxygen content was normal in the cirrhosis patients. The oxygen tension and saturation were always higher in the splenic vein than in the other branches of the portal system. Oxygen was supplied chiefly by the hepatic artery, and arterial oxygen extraction was normal in cirrhosis. In addition, there was no change in arterial extraction during oxygen inhalation by cirrhosis patients. Portal venous oxygen extraction was decreased in cirrhosis and was increased by oxygen inhalation. These findings indicate the autoregulation of hepatic oxygen through a mutual relationship between the hepatic arterial and the portovenous oxygen supply. 相似文献

Portal hypertension is a predictor of liver‐related clinical events and mortality in patients with hepatitis C and cirrhosis. The effect of interferon‐free hepatitis C treatment on portal pressure is unknown. Fifty patients with Child‐Pugh‐Turcotte (CPT) A and B cirrhosis and portal hypertension (hepatic venous pressure gradient [HVPG] >6 mm Hg) were randomized to receive 48 weeks of open‐label sofosbuvir plus ribavirin at Day 1 or after a 24‐week observation period. The primary endpoint was sustained virologic response 12 weeks after therapy (SVR12) in patients who received ≥1 dose of treatment. Secondary endpoints included changes in HVPG, laboratory parameters, and MELD and CPT scores. A subset of patients was followed 48 weeks posttreatment to determine late changes in HVPG. SVR12 occurred in 72% of patients (33/46). In the 37 patients with paired HVPG measurements at baseline and the end of treatment, mean HVPG decreased by ‐1.0 (SD 3.97) mm Hg. Nine patients (24%) had ≥20% decreases in HVPG during treatment. Among 39 patients with pretreatment HVPG ≥12 mm Hg, 27 (69%) achieved SVR12. Four of the 33 (12%) patients with baseline HVPG ≥12 mm Hg had HVPG <12 mm Hg at the end of treatment. Of nine patients with pretreatment HVPG ≥12 mm Hg who achieved SVR12 and completed 48 weeks of follow‐up, eight (89%) had a ≥20% reduction in HVPG, and three reduced their pressure to <12 mm Hg. Patients with chronic HCV and compensated or decompensated cirrhosis who achieve SVR can have clinically meaningful reductions in HVPG at long‐term follow‐up. (EudraCT 2012‐002457‐29). 相似文献

Abstract Objective. To examine the efficacy of saline-enhanced ultrasound (US) in predicting the X-ray appearance of hepatic venography. Materials and methods. This prospective study consisted of 50 cirrhosis patients (31 males and 19 females; mean age, 64.2 ± 11.1 years). US patterns in the liver, after injection of agitated saline via balloon-occluded catheter, were evaluated with respect to the findings of CO2-enhanced hepatic venogram. Results. US demonstrated two patterns: type I showing positive parenchymal enhancement (40 patients) and type II showing negative parenchymal enhancement with detection of hepatic vein (10 patients). There were also two patterns shown by hepatic venography: type A showing retrograde detection of intrahepatic portal vein (41 patients) and type B showing hepatic venous enhancement via intrahepatic venous–venous communications with no detection of intrahepatic portal vein (9 patients). All patients with type I showed retrograde detection of intrahepatic portal vein via hepatic sinusoid on X-ray venograms (type A). Of the 10 patients with type II, nine showed type B and one showed type A. Sensitivity and specificity of type I US pattern to predict the detection of intrahepatic portal vein on the venogram were 100% and 90%, respectively. There was no significant difference in hepatic venous pressure gradient or wedged hepatic venous pressure between patients with type I and type II. Conclusions. Saline-enhanced US is effective in predicting the findings of hepatic venogram. As type II strongly suggests the shunt-modified venogram, image taking in these cases would be superfluous with the added advantage of avoiding unnecessary radiation exposure. 相似文献

Abstract The relationship between the severity of cirrhosis and systemic and hepatic haemodynamic values was evaluated in 193 patients with cirrhosis, most of whom were diagnosed with post-necrotic cirrhosis. It was found that the hepatic venous pressure gradient and cardiac output in Pugh's A patients (13.6 ± 4.8 mmHg and 6.2 ± 1.6 L/min, mean ± s.d.) were significantly lower than in both Pugh's B (16.8 ± 4.3 mmHg and 7.3 ± 2.1 L/min) and Pugh's C (18.8 ± 5.5 mmHg and 7.4 ± 2.3 L/min) patients ( P < 0.01), respectively. In contrast, the systemic vascular resistance in Pugh's A patients (1232 ± 369 dyn/s per cm5 ) was significantly higher than in both Pugh's B (1016 ± 345 dyn/s per cm5 ) and Pugh's C (935 ± 234 dyn/s per cm5 ) patients ( P < 0.01), respectively. Additionally, not only was there a positive correlation found between Pugh's score and cardiac output and hepatic venous pressure gradient, but a negative correlation was found between Pugh's score and systemic vascular resistance. It was also confirmed that the degree of portal hypertension and the hyperdynamic circulation were more severe in patients with ascites than in those without ascites. However, there were no statistically significant differences in hepatic venous pressure gradient among patients with F1, F2 and F3 esophageal varices (15.7 ± 4.0, 17.0 ± 4.8 and 18.0 ± 4.8 mmHg, respectively). It is concluded that in those patients with cirrhosis, the severity of cirrhosis is closely related to the degree of the hyperkinetic circulatory state and portal hypertension. 相似文献

Umbilical Vein Recanalization (UVR) may occur in patients with long-standing portal hypertension and liver cirrhosis. This study aimed to investigate the clinical significance of UVR.Medical records of a cohort of patients with cirrhosis (n = 247) who were hospitalized at the Digestive Medicine Center of the Second Affiliated Hospital of Nanchang University from January 2012 to October 2015 were accessed. The UVR diagnosis was made by ultrasound examination and was confirmed by computerized tomography scan.The UVR incidence was 20.2% (50/247) in the cohort. The size of UVR was 9.9 ± 4.7 mm (range: 5–26.5 mm) in diameter. The UVR and non-UVR groups showed no difference in grades of hepatic encephalopathy (P = .496), Child-Pugh classification (P = .401), the incidence of moderately severe ascites (26% vs 26%, P = 1), the esophageal variceal bleeding rate (32% vs 39%, P = .402), or portal vein thrombosis (8% vs 12%, P = .580). However, the incidence of cavernous transformation of the portal vein was statistically different, that there was 0 case in the UVR group and 8 cases in the non-UVR group (P < .05).Our results suggested that UVR had little impact on the clinical manifestations of patients with liver cirrhosis, the significance of UVR as an intervention method requires further studies. 相似文献
