The prevalence of spontaneous reversal of flow in the portal venous system was non invasively evaluated by Doppler ultrasound in 228 patients with liver cirrhosis and portal hypertension. Reversed flow was detected in the portal vein in 7 patients (3.1%), in the splenic vein in 7 patients (3.1%), and in the superior mesenteric vein in 5 patients (2.1%),(More)
OBJECTIVE The objective of our study was to prospectively compare the diagnostic value of sonography and contrast-enhanced sonography with CT for the detection of solid organ injuries in blunt abdominal trauma patients. SUBJECTS AND METHODS Sonography, contrast-enhanced sonography, and CT were performed to assess possible abdominal organ injuries in 69(More)
An increase in splanchnic blood flow in both arterial and venous beds has been demonstrated in inflammatory bowel disease (IBD) by means of angiographic and scintigraphic studies. Doppler ultrasound (US) enables a non-invasive evaluation of splanchnic arterial inflow in the superior mesenteric artery (SMA) and of venous outflow in the portal vein. The aim(More)
The authors compared the Doppler ultrasonographic pattern of hepatic veins (HVs) in a group of 60 patients affected by liver cirrhosis and in 65 healthy subjects comparable for sex and age to (a) detect possible differences in HV waveform in the two groups and (b) investigate the relationship of these differences with the severity of the disease (according(More)
OBJECTIVE Our study assessed the feasibility of detecting and measuring by sonography the diameter of the thoracic duct in healthy subjects and in patients with cirrhosis and portal hypertension. We also evaluated the relationship of thoracic duct size with age and with clinical, endoscopic, and sonographic signs of portal hypertension. SUBJECTS AND(More)
To establish the sensitivity and specificity of the mean portal flow velocity in the diagnosis of portal hypertension, a population of 304 consecutive cirrhotic patients, in whom 246 abdominal Doppler examinations were performed, was prospectively analysed between June 1988 and December 1990. To avoid equipment-related variability only examinations(More)
OBJECTIVE The aim of this study was to identify the most common patterns of various common liver lesions at real-time contrast-enhanced ultrasonography with second-generation contrast agents and their role in the differentiation of malignant from benign lesions. PATIENTS AND METHODS The enhancement pattern in the arterial phase and its modifications in(More)
BACKGROUND Hepatocellular carcinoma (HCC) is a major cause of death in cirrhotic patients. This neoplasm is associated with liver cirrhosis (LC) in more than 90% of cases. Early diagnosis and treatment of HCC are expected to improve survival of patients. AIMS To assess the cost effectiveness of a surveillance programme of patients with LC for the early(More)
We analyzed the growth pattern of tumor masses and the survival of 39 asymptomatic Italian patients with a total of 59 small (less than or equal to 5 cm in diameter) hepatocellular carcinomas arising from cirrhosis. The total length of the observation period ranged from 90 to 962 days, with an average of 364 +/- 229 (mean +/- S.D.). Doubling time ranged(More)
The effect of a standard Italian meal on portal hemodynamics was evaluated in 12 normal subjects, in 11 patients with chronic active hepatitis and in 11 patients with liver cirrhosis using duplex Doppler ultrasound, which allows a noninvasive assessment of portal blood flow. In the fasting state, the portal vein caliber was significantly higher in patients(More)
