XXXX after liver transplantation.

@entity1 @entity715 @entity450
When @entity715 occurs after liver transplantation, another transplantation is required to ensure the @entity1 's survival. Because of the importance of establishing this diagnosis, we reviewed the results of duplex sonography in 37 angiographically or surgically proved cases of @entity715 after liver transplantation. There were 20 @entity1 and 17 adults. Ten of the 20 @entity1 had angiographically documented hepatopetal arterial collaterals. Such collaterals were not seen in the adult @entity1 . This subset of @entity1 was evaluated separately to determine if intrahepatic arterial blood flow reestablished by collaterals after @entity715 was a cause of false-negative Doppler studies. Thirty-four (92%) of the 37 cases of @entity715 were correctly identified by Doppler. A Doppler pulse was not identified in any of the @entity1 with arterial collaterals. We conclude that duplex sonography is sensitive in detecting @entity715 after liver transplantation. Furthermore, the presence of blood @entity450 does not cause false-negative examinations.
