heart. Twin reversed arterial perfusion (TRAP) sequence occurs when an acardiac twin receives all of the blood supply from the normal "pump" twin. This only occurs in monochorionic twins. Blood enters the acardiac twin in a reversed perfusion manner. Blood enters this fetus via an umbilical artery and exits via the umbilical vein. The excessive demands on the normal "pump" twin can cause cardiac failure in that twin. • Twin-to-twin transfusion syndrome: This syndrome occurs in monochorionic/monoamniotic or monochorionic/diamniotic twins. Vascular anastomoses in the monochorionic placenta result in transfusion of blood from one twin (ie, donor) to the other twin (ie, recipient). One classification scheme separates TTTS into severe, moderate, and mild forms. o Severe TTTS presents early in the second trimester (16-18 weeks' gestation). A difference of more than 1.5 weeks' gestational size between twins occurs. Severe TTTS has a 60-100% mortality rate. Polyhydramnios develops in the sac of the recipient twin because of volume overload and increased fetal urine output. Oligohydramnios develops in the sac of the donor twin because of hypovolemia and decreased urine output. Severe oligohydramnios can result in the stuck twin phenomena in which the twin appears in a fixed position against the uterine wall. o Moderate TTTS develops later at 24-30 weeks' gestation. Although a fetal size discrepancy of more than 1.5 weeks' gestation occurs, polyhydramnios and oligohydramnios do not develop. The donor twin becomes anemic, hypovolemic, and growth retarded. The recipient twin becomes plethoric, hypervolemic, and macrosomic. Either twin can develop hydrops fetalis. o Mild TTTS develops slowly in the third trimester. Polyhydramnios and oligohydramnios usually do not develop. Hemoglobin concentrations differ by more than 5g/dL. Twin sizes differ by more than 20%. Polycythemic twins can develop hyperviscosity syndrome and hyperbilirubinemia after birth. • Conjoined twins: Incomplete late division of monozygotic twins produces conjoined twins. Conjoined twins are connected at identical points and are classified according to site of union. o Thoracopagus - Joined at chest (40%) o Xiphopagus/omphalopagus - Joined at abdomen (34%) o Pygopagus - Joined at buttocks (18%) o Ischiopagus - Joined at ischium (6%) o Craniopagus - Joined at head (2%) • Intrauterine growth retardation: Birth weights of twins, triplets, etc. are smaller than weights of corresponding singletons. However, when combined, birth weights of twins are greater than weights of corresponding singletons. Most of the deficit of birth weight occurs in the final 8-11 weeks of pregnancy. Average birth weights are similar between twins and singletons until 32 weeks of gestation. Average birth weights are similar between triplets and singletons until 29 weeks of gestation. Birth weight discrepancies of more than 20-25% are considered discordant. Discordant birth weights occur in 10% of twins. The cause of discordant birth weights among twins is the difference between each twin's placental surface area or TTTS. Discordant birth weights among triplets are more common than discordant birth weights between twins. Approximately 30% of pregnancies with triplets have a birth weight discordance of more than 25%. Prognosis: • The prognosis of infants born from multiple gestations depends upon the complications that develop. Some studies have reported that the risks of death, chronic lung disease, and grade III/IV intracranial hemorrhage were similar in twins and singletons. Other studies have reported a higher prevalence of complications such as necrotizing enterocolitis, retinopathy of prematurity, and patent ductus arteriosus in infants from multiple gestation versus singletons.
MISCELLANEOUS Section 7 of 9 Medical/Legal Pitfalls: Most problems that could result in medical legal action against the health professional involve prenatal and intrapartum care issues. Special Concerns: Multiple births have significant economic implications. Twins and triplets have more frequent and longer duration hospitalizations than singletons. Multiple births contribute disproportionately to inpatient hospital costs in the first 5 years of life. PICTURES Section 8 of 9 Picture 1. Diamniotic, dichorionic placentation. Picture 2.
