Case report-fetal major anomaly-human cyclops fetus acardia

Abstract

Twin Reverse Arterial Perfusion Sequence (TRAP), refers to a rare, unique complication of mono-chorionic twin pregnancy in which a twin with an absent or a nonfunctioning heart (acardiac twin) is perfused by its co-twin (pump twin) via placental arterial anastomoses. The acardiac twin usually has a poorly developed heart, upper body and head. The pump twin is at risk of heart failure and problems related to preterm birth. Early diagnosis of acardiac twin by ultrasonography and color Doppler is essential for timely management and preventing complications like preterm delivery, cardiac failure and intrauterine fetal death of ‘pumpco-twin’. This case report presents an antenatally diagnosed mono-chorionic twin pregnancy, resulting in preterm delivery of a healthy, normal twin along with an acardiac co-twin.
