Exclusive complication of monochorionic twins-

Ans. is 'b' i.e., Twin to twin transfusion Complications of mcinochor ionic twinsTwin to twin transfusion:-o It is a clinicopathological state, exclusively occurring in monozygotic twins, where one twin appears to bleed into other through placental vascular anastomosis. As a result receptor twin becomes larger with hvdramnios, polycythemic, hypertensive and hypervolemic at expense of donor twin who becomes smaller with oligohydramnios, anaemic, hypotensive and hypovolemic.Dead fetus syndrome:-o Death of one twin is associated with poor outcome of the co-twin.Twin reversed arterial perfusion (TRAP) :-o Characterized by acardiac perfused twin having blood from co-twin via large arterial to arterial or vein to vein anastomosis. In majority co-twin dies (in perinatal period) due to high output cardiac failure.MonoamniocityConjoined twins
