Abstract
We report a case of renal transplantation in a child who developed pericardial effusion perioperatively. A 10-year-old girl was scheduled to undergo ABO-incompatible kidney transplantation. She underwent a preoperative plasma transfusion. Perioperative blood loss was over 1,500ml and a large quantity of blood was required. Perioperative transesophageal echocardiography revealed pericardial effusion expanding in a short time about 4 hours after the operation started. The authors consider that in the present case, pericardial effusion expanded due to severe blood loss and a large blood transfusion, in addition to the influence of the preoperative plasma exchange. In the present case, TEE was a useful monitor for detecting pericardial effusion.
