Twin pregnancy acardio anceps (das. k.1902). Presentation of a case

The TRAP (reverse arterial perfusion sequence) is a series of complications in monochorionic twin pregnancy in which the affected twin (fetus with cardia) is perfused backwards by the ''pumping'' twin through a large arterio-arterial (A-A) and veno-venous (V-V) anastomosis in which the twin with cardiac arrest is born with a somewhat developed body and limbs but a partially formed head and face due to a reduced supply of oxygen and nutrients; with severe malformations an abnormal lack of development that in 50% of cases the normal twin dies because of heart failure and prematurity. We present a case of acardio anceps fetus (Das K.1902) female for the first time for the Department of Sucre Colombia S.A.; product of a multiple pregnancy of a mother of 23 years from Centro Alegre Tuchin Cordoba referred by a gynaecological specialist in Asplejo.
