title: Biliary complications after transplantation in children: role of imaging modalities.
abstract: Among a series of 140 liver transplantations in children, 21 biliary complications (BC) (15%) are reported. BC were identified from 2 days to 3 months after LT. Positive US findings were present in 20 cases. Cholangiography was obtained by opacification of a surgical drain in 3 cases, per-operatively in 3 and by PTC in 15. Drainage was placed in 9 and balloon dilatation performed in 2. Causes of BC include hepatic artery (HA) thrombosis in 7, HA stenosis in 1, anastomosis stricture in 7, anastomosis kink in 3, mucocele of cystic duct remnant in 2 and sludge in 1. Treatment was surgical in all, but 2 cases were treated percutaneously. There is a great difference in severity of prognosis between complications secondary to HA thrombosis and isolated BC. Role of US in diagnosis and of PTC and interventional radiology in treatment are emphasized.
