ABSTRACT
Over a period of 22 years, 154 fetuses were treated with 270 intra-uterine intraperitoneal transfusions. The patients were divided into three groups, according to the period they were treated. The overall percentage of surviving infants increased from 33% during the first period to 58% in the last period. In the group of infants that were not hydropic at the time of the first transfusion, the survival rate increased from 35 to 83%. In the group of children that were hydropic during the first transfusion, the survival rate during the first and last period was 24 and 42%, respectively. The percentage of fetuses that needed their first transfusion before the 26th week of pregnancy increased from 15 to 32% during the study period. Only 13% of these children survived. Lately, the intravascular approach has been introduced. Intravascular transfusions seem to be very effective, especially in early pregnancies and in hydropic fetuses. Application of the two techniques each in the most appropriate situation might offer optimal results for the near future.
