title: [The echographic aspects of the splenoportal axis in patients with esophageal varices].
abstract: In the present study the A. try to assess the usefulness of ultrasound in detecting blending risk in portal hypertension. Endoscopic and sonographic findings of 35 cirrhotic patients with esophageal varices were compared to a control group of 27 hepatopathy patients without portal hypertension, observed in the same department and in the same interval. The medium caliber of portal vein was 14.64 +/- 2.59 and 11.8 +/- 1.33 mm, respectively in the study and in the control group (p less than 0.01). Statistic correlations were also found in subgroups of patients with varices of different degrees. A portal vein greater than 16 mm was found in 10 of 11 patients with large varices; this pattern provides a sensitivity of 71.4% and a specificity of 94.1%. In our experience this echographic finding should represents a clear indication for close endoscopic follow-up, even in patients without previous bleeding from esophageal varices.
