Feto acardio en gestación gemelar monocorial biamniótica. Síndrome de perfusión arterial inversa gemelar

Multiple gestations involve an exacerbation of the signs and own symptoms of the pregnancy, and suppose a situation of risk for the mother as for the fetuses.One of these complications is the twin reverse arterial perfusion (TRAP), a very rare process (1% of the multiple gestations) or 0,3/10000 borned alive, that consists of the coexistence of a normal fetus (called “pump”) and an acardiac fetus.The abnormal fetus, displays, in most of the cases, incomplete development of the cephalic pole, heart, superior members and numerous organs. The lower members are relatively well conserved although the foot is usually bad conformed as well as the anomalies in the toes are frequent. Is frequent the edema in superior half of the fetus.We displayed an agreed case about this matter occurred in our hospital.
