Abstract

Authors investigate in a retrospective study obstetrical and genetical data in 20 years period of 149 pregnancies of patients turning to genetical counselling because of haemophilia A and B. In case of heterozygote mother there have been fetal determination of sex, and in case of male fetus, there have been DNA examination in 23 of the 35 cases. In case of sick male fetus the couple made a decision on keeping the pregnancy or not, knowing well the genetical risk. Haemophilia A occurred in case of 135 pregnancies (98 pregnancies of 55 heterozygote mothers, and 37 pregnancies from 20 sick fathers). Haemophilia B occurred in case of 14 pregnancies (9 pregnancies of 3 heterozygote mothers, and 5 pregnancies from 4 sick fathers). In case of haemophilia A heterozygote pregnant women there were 32 proven male fetuses, and in 22 cases there have been DNA examinations. In 16 cases there have been artificial abortions (in 10 cases proven disease by DNA examination), and 4 sick male newborns were born from the 16 deliveries (the disease was proven during pregnancy by DNA examination). One male newborn (healthy) was born from the 3 proven male fetuses of haemophilia B heterozygote pregnant women, in 2 cases there have been artificial abortions (in one case on the basis of DNA diagnostics). In cases of heterozygote mothers (haemophilia A and B altogether) the ration of the spontaneous abortions was 13.1%. The rations of the premature deliveries (8.2%) and the Caesarean sections (8.2%) were not higher than the national average. The ration of the bleeding complications during pregnancy was 18.7%, in 2.7% of the cases transfusion was necessary. In case of sickness of the father (in heterozygote female fetuses the haemostasis may change from the fetal side) the ration of the bleeding complications during pregnancy was 18.2%. In connection with delivery, obstetrical bleeding complications occurred in 12.2%, atonia in 2%, abrasion after delivery in 4.1, transfusion in 10.2% in cases both of haemophilia A and B heterozygote mothers. From the neonatological complications in one case there was cerebral haemorrhage, and in one case bleeding from the umbilical stump. (Both newborns were male with haemophilia.) In connection with delivery there was no haematoma developing on the skull of the newborns, there was no need of giving transfusion. In case of sickness of the fathers the ration of the instrumental uterine examination was 6.7%, there were no neonatological and other obstetrical complications.
