  • Title: [Spontaneous portasystemic shunt in liver cirrhosis: imaging with color-coded duplex ultrasonography].
    Author: Riehl J, Bongartz D, Nguyen H, Sieberth HG.
    Journal: Ultraschall Med; 1997 Dec; 18(6):272-6. PubMed ID: 9491495.
    Abstract:
    PURPOSE: To demonstrate the usefulness of B-scan ultrasonography and color Doppler ultrasonography (CCDS) in the diagnosis of lumbal and splenorenal collateral veins in patients with liver cirrhosis. METHOD: 46 patients with histologically proven liver cirrhosis were examined by means of B-scan ultrasonography. CCDS was used to demonstrate the vascular character of mass-like lesions or tortuous tubular structures. Esophageal varices were demonstrated in 23 (50%) and ascites in 6 patients (13%). RESULTS: In 5 out of 46 patients (10.9%) we demonstrated lumbal and splenorenal portosystemic venous collaterals by B-scan- and CCDS. In 2 patients localized venous collaterals were demonstrated. No ascites was found in patients with accessory portosystemic shunts. CCDS showed the patency of these spontaneous portosystemic shunts. CONCLUSION: 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.
