Abstract

|
Twin-to-twin transfusion syndrome (TTTS) is a severe complication of monochorionic twin pregnancies, characterized by the development of unbalanced chronic blood transfer from one twin, defined as donor twin, to the other, defined as recipient, through placental anastomoses. The incidence of TTTS in monochorionic diamniotic gestations is approximately 10% to 20%. The natural history of severe TTTS is well established with mortality approaching 80% to 100% if left untreated, especially when it presents at less than 20 weeks’ gestation. This review presents overview of what is known about the pathophysiology and the diagnosis of TTTS, the markers for early detection of TTTS, treatment options available for TTTS, and complications of treatment for TTTS.
