The radiographic findings of post-transplantation lymphoma in 15 patients are demonstrated. Variations in patterns from those of lymphomas in nonimmunosuppressed patients, etiologic factors, histologic features, and differential diagnosis are discussed. The common finding of central lucency of masses seen on CT scans correlated with necrosis seen at histologic examination. In the post-transplant patient, single or multiple masses, particularly if centrally lucent, should suggest post-transplantation lymphoma. Histologic proof with anatomic localization is important, however, to determine appropriate therapy.
Blood component use during orthotopic liver transplantation (OLT) was evaluated after an initial 23-month experience with 37 consecutive transplant procedures. Blood component support of OLTs in 24 adult and 13 pediatric patients was reviewed. Adult procedures required intraoperatively a mean of 24.5 units of red cells (RBCs), 38.7 units of fresh-frozen plasma (FFP), 26.1 random-donor platelets (RDP), and 12.2 units of cryoprecipitate (Cryo); pediatric procedures required 4.8 units of RBCs, 5.8 of FFP, 3.9 of RDP, and 1.2 of Cryo. RBC salvage constituted 17 percent of the RBCs transfused intraoperatively. Intraoperative support in adult and pediatric OLT patients accounted for the majority of the total components required for the entire hospital stay. OLT blood component use constituted 1.3, 7.0, 3.6, and 8.1 percent of hospital-wide use of RBC, FFP, RDP, and Cryo, respectively, during the period of the study.
Approximately 6,000 to 7,000 orthotopic liver transplantation (OLT) procedures are performed annually, which require the administration of large volumes of blood products. Thus liver transplantation can significantly strain local and regional blood resources at a time when transfusion practices are changing dramatically, in large part because of anxiety caused by the human immunodeficiency virus. Intraoperative autologous transfusion has been proposed as a means of both reducing transfusion demands and lessening the hazards of allogeneic transfusion. However, the cost effectiveness of intraoperative blood salvage has not been unequivocally determined. We retrospectively examined the cost of intraoperative autologous transfusion during OLT for a 2-year period at the University of Cincinnati Hospital.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
