[Asynchronous twin births. Case report and obstetric management review].

BACKGROUND

The incidence of multiple pregnancy has increased in the last years. These pregnancies are associated with more obstetric complications regarding single pregnancies, one of the most important is prematurity. In extremely rare cases premature delivery of one fetus may occur, being retained in the uterine cavity the second fetus until birth later, producing the so-called delayed delivery of twins.

CASE REPORT: We report the case of a double twin pregnancy with delayed delivery of the second fetus after birth of the first one within 22.6 weeks of gestation and the second one birth at at 24 weeks of gestation, eight days later after the first one. A review of cases published in the literature is performed and the obstetric management of delayed delivery discussed.
