Spontaneous septostomy in a monochorionic diamniotic twin pregnancy is a rare phenomenon. We present a case of monochorionic diamniotic twin pregnancy with an intact dividing membrane seen in the 1st half of the pregnancy. At 26 weeks, when she was assessed for preterm contractions, the dividing membrane was not documented, which suggested spontaneous septostomy. There had been no invasive proc...
OBJECTIVE To evaluate whether a history of preterm birth or small for gestational age (SGA) in a singleton pregnancy is associated with an increased risk of recurrence of the same condition in a subsequent twin pregnancy. METHODS Retrospective cohort study of twin pregnancies delivered in one maternal-fetal medicine practice from 2005 to 2014. Patients with a history of singleton preterm birt...
The common management in most centers in cases of multiple pregnancies with preterm premature rupture of membranes (PPROM) before 22 weeks of gestation is termination of the pregnancy or the expectant approach. Expectant management of previable PPROM in twin pregnancies results in an increased rate of fetal and neonatal morbidity and mortality of both twins. Selective fetocide of the twin with ...
It is well established that the death of one fetus in a monochorionic twin pregnancy places the surviving twin at significant risk for neuro-developmental delay or death. Although the early 1st trimester "vanishing twin" has not traditionally been considered a major risk, the precise gestational threshold beyond which a surviving twin is at risk remains uncertain. Most experts recommend serial ...
A case report of primary twin ovarian pregnancy is presented. A 36 year old woman, gravida 4 para 3, was admitted to the hospital for suspected ectopic pregnancy, with vaginal bleeding at 11 weeks after her last menstrual period, associated with pelvic pain. An endovaginal ultrasonography led to the diagnosis of twin ovarian right ectopic pregnancy with two dead fetuses associated with a compar...
Retrospective assessment of maternal smoking or substance use during pregnancy is sometimes unavoidable. The unusually close relationship of twin sister pairs permits comparison of self-report data versus co-twin informant data on substance use during pregnancy. Information about smoking during pregnancy has been gathered from a series of mothers from an Australian volunteer twin panel (576 wom...
A chromosomal abnormality in one of the fetuses of a monozygotic twin pregnancy is a rare phenomenon. In the prenatal unit of our cytogenetics laboratory we have recently come across two such heterokaryotypic twin pregnancies. In both cases ultrasound abnormalities were detected in one fetus of each twin pair. Chromosomal analysis showed that one twin pregnancy was discordant for trisomy 21 and...
