Yapicioglu-Yildizdas H, Ece Ü, Sucu M, Yurdakul G, Simsek H, Özlü F. Twin reversed arterial perfusion syndrome in a monochorionic monoamniotic twin pregnancy. Turk J Pediatr 2017; 59: 724-727. Twin reversed arterial perfusion syndrome is mostly seen in monochorionic diamniotic twin pregnancies with an estimated incidence of 1/9500-11000 pregnancies. One of the twins is acardiac with various abnormalities especially with upper part of the body, and mortality is 100%. The other twin functions as a pump twin and mostly has polyhydramnios and heart failure; and mortality rate is high due to prematurity and heart failure. Herein we report a TRAP syndrome and the prognosis of pump twin who was born at 30 weeks gestational age.
