If an insufficient blood circulation of the blood vessels supplying the uterus is diagnosed as a result of the obstetric ultrasonography, we will speak of a pathological duplex result. A conspicuous finding in the blood vessels supplying the uterus, and thus also the afterbirth and the child, can mean that the child is not adequately supplied during pregnancy. This slows the growth of the child during the pregnancy, sometimes it does not grow at all anymore. We then speak of an intrauterine growth retardation, the risk of which is approximately 30% probable at this stage. Depending on how early this occurs during pregnancy and how strongly it is pronounced, this can have serious consequences for the child. Often, these children must be born earlier. In many cases, the physicians have to recommend a cesarean section as the child is no longer able to withstand the stress of a natural birth as a result of the undersupply. In extremly seldom, and extremly severe cases, the child may even die in the mother's body.

Now it is the case, that physicians have not scientifically yet fully understood why it comes to such inappropriate nourishments. Many medicines have been tested in recent decades and it has been shown that an improvement can be achieved with Pentalong®.A small study by the University Women 's Clinic in Jena has shown that in this situation the patient was able to achieve a significant improvement in the further pregnancy. It was found that the children of the women who took Pentalong® were less severely affected by a growth delay and their consequences.

In addition, it could be shown in this connection that the use of the drug is well tolerated during pregnancy and the drug can not pass over the afterbirth to the child.

Additional informationen about the PETN study can also be found at the german clinical trial register.
