Abstract
Acardiac twin is an extremely rare and bizarre complication of monochorionic twin pregnancy occurring at an incidence of 1 in 34,600 deliveries or 1 % monozygotic twins [1]. It is also referred to as TRAP Sequence (Twin Reversed Arterial Perfusion) where as a result of arterial–arterial and venous–venous anastomoses without any arterial–venous connection, the acardiac (since it has no heart of its own) thrives as a parasite by getting blood supply from the donor hydropic twin [2]. Acardius is commonly associated with acephaly and failure of development of most of the thoracic organs and upper limbs. We present a case report of Acardius acephalic twin which was retrospectively diagnosed following twin delivery of an unbooked pregnant woman admitted to our hospital.
