Abstract
ABSTRACT Twin-twin transfusion syndrome (TTTS) is a complication unique to monochorionic twin pregnancies, in which the two twins share a common placenta and unequal blood exchange from one twin (donor) to the cotwin occurs through placental arterovenous anastomoses. The diagnosis is posed with the sonographic detection of oligohydramnios in the donor's sac, as a consequence of hypovolemia, and polyhydramnios in the recipient's sac, resulting from hypervolemia. The severity of TTTS is assessed according to Quintero staging system, which is based on five stages that range from visualization of the donor's bladder to intrauterine demise of one or both twins. Because laser therapy has revealed the optimal treatment for TTTS, management of twins affected with TTTS consists in preoperative and postoperative assessment of the twins by ultrasound examination. The aim of this review was to describe the diagnosis and management of TTTS and discuss controversies and limitations of current literature. How to cite this article Rossi AC, D'Addario V.
