OBJECTIVE This article shows our experience with fetal and neonatal alloimmune thrombocytopenia (FNAIT) on a particular patient and the difficulties we faced during the hospitalization. METHODS Case report. METHODS Department of Obsterics and Gynecology 1st Faculty of Medicine, Charles University and General Faculty Hospital in Prague. METHODS Our experience with FNAIT therapy. RESULTS According to literature is recommended to use IVIG for FNAIT treatment. Women, who were treated by IVIG have better results, in comparison with women, who had no treatment at all. Our case is not confirming this statement, because first pregnancy of our patient terminated by IUFD, on the other hand second pregnancy was successful and she delivered healthy child. CONCLUSIONS FNAIT is relatively rare disease, but if it appears, it can be dangerous for a fetus or for a new-born baby. In the worst case FNAIT can result in intracranial bleeding or prenatal death. There are limited preventive steps and available therapy produces uncertain results. The only partially accepted treatment substance is IVIG (intravenous immunoglobulins). Unfortunately, this therapy is very expensive and not accepted by some experts. This article shows our experience with FNAIT on a particular patient and the difficulties we faced during the hospitalization.
