Complications arising in twin pregnancy: findings of prenatal ultrasonography.

Kim JA, Cho JY, Lee YH, Song MJ, Min JY, Lee HJ, Han BH, Lee KS, Cho BJ, Chun YK - Korean J Radiol (2003 Jan-Mar)

Bottom Line: Multifetal gestations are high-risk pregnancies involving higher perinatal morbidity and mortality, and are subject to unique complications including twin oligohydramnios-polyhydramnios sequence, twin-to-twin transfusion syndrome, acardiac twins, conjoined twins, co-twin demise, and heterotopic pregnancies.The purpose of this study is to describe the prenatal ultrasonographic and pathologic findings of these complications.

Sonographic findings of monochorionic diamniotic twins with co-twin demise.A. Ultrasonogram obtained at gestational age 14 weeks shows a fairly-well visualized (short arrow) but preserved (arrowheads) thin intertwin membrane with a single placenta, and intrauterine fetal death of one fetus with diffuse soft tissue edema (arrows).B. Ultrasonogram obtained at gestational age 23 weeks depicts an enlarged umbilical cord (arrow) in the surviving fetus.C. Cardiomegaly with thickened biventricular walls (arrows) developed in the surviving fetus.

Mentions: Single fetal death during the first trimester is relatively common and the course of the pregnancy is usually not impaired. The incidence of spontaneous single fetal loss after the second trimester is 2.6-6.8% (12), while that of perinatal mortality and morbidity of the second twin varies. In monochorionic pregnancies the risk of these is greater (Fig. 5), and repots have described increased risk of neurologic injury including cerebral necrotic lesion due to thromboembolic material, hemodynamic change such as anemia or hypotension in TTTS, and premature delivery (13).
