INCREASED RISK FOR ABNORMAL PLACENTATION IN WOMEN AFFECTED BY MYOTONIC-DYSTROPHY

The obstetric histories of 26 women with myotonic dystrophy, who had a total of 66 life births, mere reviewed by means of questionnaires and medical reports. Six patients (23%) each had one pregnancy complicate d by placenta praevia (affecting 9% of all completed pregnancies), poi nting toward a susceptibility to abnormal placentation in this disorde r. As involvement of the genitourinary tract is common in myotonic dys trophy, an increased risk for placenta praevia has to be considered in the antenatal care of these patients.
