Hj. Steinkamp et al., COLOR DUPLEX SONOGRAPHY (CDS) OF LIVER-TR ANSPLANTS - ITS VASCULAR STATUS, RoFo. Fortschritte auf dem Gebiete der Rontgenstrahlen und der neuenbildgebenden Verfahren, 159(3), 1993, pp. 222-228
The present study deals with the value of CDS in liver transplantation
. Between September 1988 and October 1991 CDS of hepatic vessels was c
arried out in 194 liver transplants. Flow direction and flow velocity
in the portal vein could be demonstrated in 97 %. Measurement of flow
velocity indicates the extent of portal hypertension; this can be conf
irmed by determining flow direction in the splenic and superior mesent
eric veins. In 47 of 179 patients venous collaterals were demonstrated
and in 15 of 179 patients there was retrograde flow in the splenic ve
in. In 95 % of patients CDS indicated flow direction in the hepatic ar
tery and in 93 % in the hepatic veins. Thrombosis of liver vessels (po
rtal and hepatic veins) was demonstrated in 11 out of 13 patients by m
eans of CDS.
