Purpose The aim of the study was to evaluate the usefulness of color Doppler sonography in the detection of spontaneous portosystemic shunts and abnormal blood flow direction in the portal vein in patients with cirrhosis. Methods Patients were 67 men and 42 women (mean age, 53 ± 14 years) with cirrhosis confirmed by liver biopsy. All patients underwent abdominal gray‐scale and color Doppler sonographic evaluations to detect the presence of spontaneous portosystemic shunts and to analyze portal vein blood flow direction. Results Spontaneous portosystemic shunts were found in 41 patients (38%), most often as splenorenal shunts (21%) and patent umbilical veins (14%). Less frequent were gastric collaterals, gallbladder varices, collaterals to thrombotic portal veins, mesoiliac shunts, and portorenal shunts to the right kidney. The presence of shunts was associated with that of esophageal varices (p < 0.01), ascites (p < 0.01), and inversion of portal flow (p < 0.001) but not with splenomegaly. The direction of portal venous flow was normal (hepatopetal) in 80 patients (73%), hepatofugal in 10 (9%), and bidirectional in 7 (6%); 12 patients (11%) had partial portal vein thrombosis. Conclusions Portosystemic shunts and the direction of portal venous flow are important features in the sonographic diagnosis of portal hypertension. © 2000 John Wiley & Sons, Inc.

Purpose: To identify changes in vascular morphology on magnetic resonance imaging (MRI) in patients with cirrhosis and to compare these findings to liver donors. Materials and Methods:Patients undergoing liver transplantation with biopsy-proven cirrhosis (n ϭ 74) and liver donor candidates (n ϭ 85) underwent dynamic gadoliniumenhanced 3D MR at 1.5T. Vessel diameters were measured independently by three radiologists and features of cirrhosis were identified and correlated with cirrhosis.Results: Hepatic veins were smaller in patients with cirrhosis (4.9, 4.5, and 5.0 mm for right, middle, and left vs. 9.9, 7.6, and 8.9 mm in donors, P Ӷ 0.001) and were negatively correlated with cirrhosis (P Ͻ 0.001). Right hepatic vein (RHV) Ͻ5 mm diagnosed cirrhosis with 59% sensitivity and 99% specificity; the sensitivity and specificity were 88% and 85% for RHV Ͻ7 mm. Main portal vein was minimally larger in cirrhosis, 14 versus 12 mm (P Ͻ 0.001) in donors. Right portal veins were smaller in cirrhotic patients, 6.5 and 6.2 mm compared to 8.4 and 7.6 mm (P Ӷ 0.001), respectively, in donors. Conclusion:Vascular features of cirrhosis include small hepatic veins, minimally enlarged main portal vein, and small intrahepatic portal veins; these features may facilitate identification of cirrhosis.

Spontane portosystemische Shunts bei Leberzirrhose: Darstellung durch farbkodierte Duplexsonographie

Abstract: In patients with chronic liver disease CCDS is a noninvasive method to demonstrate spontaneous portosystemic shunts due to portal hypertension. The method provides information concerning patency and flow direction of the collateral veins.
