Three-way tie: The umbilical cord insertion site was different for each member of a set of triplets

Abstract

Baxi. Three-way tie. Am J Obstet Gynecol 2013. Case notes A 26-year-old woman, gravida 3, para 2, gave birth to spontaneous monochorionic triamniotic female triplets at 36 weeks and 1 day. They were delivered by a scheduled—and uncomplicated—cesarean section. One week earlier, ultrasonography indicated concordant growth with estimated fetal weights ranging from the 32-35th percentiles despite eccentric cord insertion for triplet A and velamentous cord insertion for triplet B. The latter was diagnosed at 19 2/7 weeks’ gestation. In fact, the weights of neonates A, B, and C were 5 lb 1 oz (2295 g), 4 lb 11 oz (2120 g), and 5 lb 12 oz (2610 g), placing them in the 7th, 3rd, and 28th weight percentiles, respectively. The largest neonate weighed 18.8% more than the smallest.
