Among a series of 90 pediatric liver transplantations, 9 cases of hepatic artery thrombosis (HAT) in 8 patients are reported. All cases were diagnosed in the first two weeks and confirmed angiographically and surgically. Clinical presentation was often unreliable with only 2 cases showing the typical pattern of massive hepatic necrosis. Five cases presented with biliary complications and in 2 cases, HAT was discovered fortuitously on duplex sonography. The role of imaging modalities is emphasized. Duplex sonography is the best non-invasive screening method and we recommend a routine daily examination in the first 2 weeks. CT is the most useful method to assess the extension of liver infarction. PTC remains necessary to evaluate biliary complications and to plant the best therapeutic approach in this devastating event. Two patients died, 2 had to be retransplanted (one patient twice) and are doing well, 2 are on a waiting list for re-transplantation and one underwent an emergency surgical arterial desobstruction and is completely asymptomatic.
