Portosystemic shunts in a large cohort of patients with liver cirrhosis: detection rate and clinical relevance.

Background: This study aimed to determine the detection rate and clinical relevance of portosystemic collaterals.

Methods: We studied 326 cirrhotics. Portosystemic collaterals, portal vein diameter, and splenic area were evaluated by color Doppler sonography; esophageal varices were detected by endoscopy.

Postmeal portal flow variations in HCV-related chronic hepatitis and liver cirrhosis with and without hyperdynamic syndrome.

Background: Doppler ultrasonography (US) of portal blood flow and portal flow volume (PFV) are useful to define changes in portal hemodynamics of patients with chronic liver diseases. The meal test with postmeal PFV measurements is generally accepted as a reproducible noninvasive test to evaluate the severity of portal hypertension. The aim of this study was to evaluate whether monitoring PFV changes after ingestion of a standard meal would be useful to characterize patients with chronic hepatitis or liver cirrhosis in the presence or absence of hyperdynamic syndrome (HS) characterized by elevated PFV, splenomegaly, systemic hypotension and/or increased cardiac output.

Pancreatitis after percutaneous ethanol injection into HCC: a minireview of the literature.

Deaths after percutaneous ethanol injection (PEI) into hepatocellular carcinoma (HCC) may occur within a few hours to a few days following the procedure because of hemoperitoneum and haemorrhage from oesophageal varices or hepatic insufficiency. Pancreatitis has been recently reported as a rare lethal complication of intra-arterial PEI, another modality for treating HCCs. In this minireview, we analyze the literature concerning the development of acute pancreatitis after PEI.

Portal diameter in the diagnosis of esophageal varices in 266 cirrhotic patients: which role?

The aim was to evaluate the predictability of portal diameter (PD) in the diagnosis of esophageal varices (EV) and of large size EV (F3EV) in a large series of patients with cirrhosis. Two-hundred sixty-six persons with cirrhosis (M:F = 153:113; mean age 65.4 +/- 10 y) were studied by abdominal sonography and upper endoscopy.

An unusual post-traumatic case of extrahepatic bile duct compression.

Jaundice and cholestatic disease by external bile duct compression may be caused by several conditions, including pancreatic masses, portal cavernoma, Ormond's disease, metastases from gallbladder cancer, neurinomas, and hydronephrotic kidney. We report a case of bile duct compression in a 56-year-old man with a known small (28 mm) right renal cyst and crossed, fused renal ectopia. The patient had a history of recent abdominal trauma due to a motorcycle accident and recurrent septic-type fever and jaundice.

[Glucagon test for Doppler sonography measurement of portal flow in chronic HCV infections].

Purpose - To evaluate whether Doppler sonography measurement of portal flow velocity (PFV) after glucagon injection can be useful in assessing the severity of liver damage in chronic HCV infection. Methods - Forty-five patients (32 males and 13 females; mean age 54.1 14.

Liver focal lesions and hepatocellular carcinoma in cirrhotic patients: from screening to diagnosis.

This short review aims at pointing out the role of ultrasonography (US) as a valuable means for an early detection of liver focal lesions in cirrhotic patients. Among these lesions which may be benign and malignant, hepatocellular carcinoma (HCC) finds its place with an incidence in cirrhotic patients becoming higher as the time passes from the onset of cirrhosis. US is of fundamental importance in the regular screening of subjects with viral cirrhosis because of its sensitivity in evaluating focal lesions (79-82%); however, it is not yet the most valuable method for the diagnosis of HCC for which other diagnostic techniques are needed such as CT (Computerized Tomography), MR (Magnetic Resonance) and the US-guided fine-needle biopsy.
