Long-term venous complications after full-size and segmental pediatric liver transplantation.

Objective: To assess the long-term incidence of venous complications, including portal vein and hepatic vein stenoses, in both whole cadaveric and reduced-size cadaveric and living related liver transplants in a pediatric population, and to assess the therapeutic modalities in the treatment of these lesions.

Summary Background Data: A shortage in appropriate-sized liver grafts for pediatric patients led to the use of segmental liver grafts, which became the predominant graft used in 325 of 600 (54%) transplants at the authors' institution. To assess the long-term impact of this strategy, the authors examined the incidence of late (>90 days) venous complications and the efficacy of all therapeutic interventions.

Thrombocytopenia in children with severe iron deficiency.

Purpose: Thrombocytopenia has been reported in some children with severe iron deficiency anemia, but the validity of the association and the mechanism of the thrombocytopenia are not well established. Six children with severe iron deficiency and thrombocytopenia are described, and the literature is reviewed.

Patients And Methods: Clinical, hematologic, and morphologic data were collected and analyzed for six patients referred for evaluation of severe microcytic anemia and thrombocytopenia.
