[Stored autologous blood from a pregnant woman showing a considerable amount of agglutinates].
A 30-year-old woman was admitted to our hospital to undergo simultaneous cesarean section and radical hysterectomy when the pregnancy became 30 weeks. An ultrasonic examination had found hypoechoic region at the cervix uteri. Because she wished autologous blood transfusion, 100 ml each of her own blood was obtained 3 times preoperatively. All the stored blood was returned to the patient through a filtering system (40 microm in the pore size) during surgery. However, we found paste-like agglutinates floating in the bags. We transfused the blood carefully while confirming that there were no agglutinates in the reservoir below the filter. The paste-like agglutinates were also found on the filter. By microscopic observation fibrin-like substances attached by blood cells were detected. When the autologous blood from pregnant women is returned, special care should be taken because the blood is likely to form agglutinates even though the blood test data are within normal ranges.
