[The case of an acardiac headless twin, review of the literature].
BACKGROUND
Monochorial twin pregnancies are characterized by the presence of vascular connections between the twins. These connections can be at the origin of pathologies such as the transfused/transfuser syndrome or the TRAP syndrome which is defined as the association of a headless, acardiac twin with a healthy twin, which is the subject we will study and then review the literature.
The case of an acardiac, headless twin which was not diagnosed during pregnancy and was discovered at birth.


CONCLUSIONS
The TRAP syndrome is a very rare phenomenon. Yet, it is crucial to diagnose it as early as possible during pregnancy so as to offer adequate supervision. It is associated to a high death rate in the healthy twin caused by anemia and heart failure. There are therapeutic means to stop vascular anostomoses between the twins so as to perform a selective feticide.
