Outcome of monochorionic twin pregnancy with selective intrauterine growth restriction according to umbilical artery Doppler flow pattern of smaller twin: systematic review and meta‐analysis

“…Among the 610 MC twin pregnancies included, 39 18 Pasquini (2015) 19 Liao (2014) 20 Zuckerwise (2015) 21 Visentin (2013) 22 Yinon (2014) 23 Lopriore (2012) 24 Ishii (2011) 25 Weisz (2011) 26 Chang (2010) 27 Machado (2014) 28 Ishii (2009) 29 Gratacós (2007) 6 Only first author of each study is given. The study can be awarded a maximum of one star for each numbered item within selection and outcome categories and a maximum of two stars for comparability.…”

Monochorionic Pseudomonoamniotic Twin Pregnancy Revealing Fetal Demise. A Unique Case

“…Focusing on pathophysiologic evaluation, an impediment in the growth of one twin greatly impacts the well-being of the other. Shared fetal circulation, consists in many cases the pathologic etiology of many complications [10]. Monitoring monochorionic twin fetuses, the deceased fetus may draw blood from living fetus (acute transfusion), associating with severe cerebral injury, due to decreased cerebral blood circulation.…”

Prevalence of umbilical artery Doppler waveform abnormality during the early second trimester and the subsequent variation of waveforms in monochorionic diamniotic twin pregnancies: A prospective cohort study

“…The assessment of UA Doppler waveforms in high‐risk pregnancies is recognized as a useful tool to reduce the risk of perinatal death 4 . Besides, the classification according to the end‐diastolic waveforms of UA Doppler in the smaller twin is useful to predict the prognosis of MCDA twins complicated with selective intrauterine growth restriction (sIUGR) 5–15 . Abnormal UA could be observed in more than half of the entire sIUGR cases 9,14,15 and in uncomplicated MCDA twins 16,17 .…”
