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 vasodilatation, 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.

Duodenal varices are a rare site of hemorrhage in patients with portal hypertension, but their rupture is a serious and often fatal event. We report a 65-year-old woman who presented with hematemesis and melena. She was admitted to our department because of prolonged shock, despite having received transfusion of a large volume of blood. Upper gastrointestinal endoscopy revealed nodular varices with active bleeding in the second portion of the duodenum. Endoscopic injection sclerotherapy (EIS) was performed using a tissue adhesive agent, alpha-cyanoacrylate monomer, with only temporary benefit. However, anemia continued to progress after the procedure. Therefore, we combined transileocolic vein obliteration (TIO) with balloon-occluded retrograde transvenous obliteration (B-RIO), using 5% ethanolamine oleate with iopamidol to obliterate the varices. Complete hemostasis was achieved without complications. Neither recurrence of varices nor further bleeding has occurred for over 3 years. We conclude that combined TIO and B-RTO, which can obstruct both the feeding and the draining vessels of duodenal varices to retain the sclerosing agent completely in the varices, is a safe and effective hemostatic measure for ruptured duodenal varices, when EIS has failed to accomplish complete hemostasis.

BACKGROUND The current study was designed to determine the usefulness of pretreatment tumor pressure as a new prognostic factor in patients with small hepatocellular carcinoma (HCC; 3 cm or smaller in diameter). METHODS The study included 39 patients with small HCC in whom tumor pressure was determined. They underwent percutaneous ethanol (with Lipiodol) injection therapy (Lp‐PEI) or transcatheter arterial embolization (TAE) of the hepatic artery. Tumor pressure was determined percutaneously under ultrasonographic guidance. The factors analyzed were age, gender, mean blood pressure, the presence/absence of antibody to hepatitis C virus (anti‐HCV), alcohol abuse, Child's classification, the presence/absence of esophagogastric varices, serum α‐fetoprotein (AFP) level, tumor size, number of tumors, degree of tumor differentiation, the presence/absence of tumor capsule, tumor pressure, and the method of treatment. Multivariate analysis using Cox proportional hazards model was conducted on the factors that may have affected prognosis (P < 0.25) according to the univariate analysis using a proportional hazards model. RESULTS The rates of local and distant recurrence were higher (P < 0.01, P < 0.01, respectively) and the survival rate was lower (P = 0.03) in patients with high tumor pressure than in those with low tumor pressure. Multivariate analysis revealed that tumor pressure (P < 0.01), AFP level (P = 0.01), and age (P = 0.01) were significant predictive factors associated with local recurrence. Tumor pressure (P < 0.01) and AFP level (P < 0.01) were both significantly associated with distant recurrence. The only significant predictive factor associated with survival rate was tumor pressure (P < 0.04). CONCLUSIONS The current study revealed that tumor pressure was associated significantly with survival rates after Lp‐PEI or TAE in patients with small HCC. There were also significant predictive factors associated with local recurrence, these being tumor pressure, AFP level, and age, and with distant recurrence, namely, tumor pressure and AFP level. Tumor pressure measured before the initial treatment of patients with small HCC may be a useful new prognostic factor. Cancer 2002;95:596–604. © 2002 American Cancer Society. DOI 10.1002/cncr.10690

The aim of this study was to determine whether endoscopic variceal sclerotherapy affects systemic or splanchnic hemodynamics.Wemeasured hemodynamic parameters before and after the first course of sclerotherapy in 35 patients with cirrhosis. Following sclerotherapy, there was a significant decrease in cardiac index and a significant increase in systemic vascular resistance. Changes in hepatic venous pressure gradient varied from patient to patient with no statistically significant change in the group overall. However, all 20 patients with a decline in the hepatic venous pressure gradient had a concomitant decrease in cardiac index and/or a large extravariceal shunt. The multivariate analysis disclosed that the decrease in cardiac index was a statistically significant contributor for the decline in hepatic venous pressure gradient. Weconclude that the obliteration ofesophageal varices by sclerotherapy significantly reverses the hyperdynamic circulatory state in patients with cirrhosis. Spontaneous changes in systemic hemodynamicsand the interaction with hepatic hemodynamics must be taken into account when evaluating hepatic hemodynamics in patients undergoing variceal sclerotherapy.
