GALVEZ, María L et al. A case report and review of the literature regarding umbilical artery Doppler with intermittent reversed flow in monochorionic biamniotic twin pregnancy with selective IUGR. Rev Colomb Obstet Ginecol [online]. 2008, vol.59, n.2, pp.155-162. ISSN 0034-7434.
Objective: this article presents a review of the existing literature on selective intrauterine growth restriction (sIUGR) in monochorionic biamniotic twin pregnancies, umbilical artery Dopplers characteristics, the pathophysiology of its typical wave forms and its implications as a prognostic factor of foetal well-being and management. A case of intermittently reversed Doppler of the umbilical artery is presented in a monochorionic biamniotic twin pregnancy discordant growth restricted foetus. Discussion: the literature review revealed that monochorionic pregnancies have different vascular connections between the foetuses, thereby making umbilical artery Doppler waves reveal a clear representation of communication patterns. There is an important correlation between Doppler wave type, clinical evolution and pregnancy outcome; however, insufficient evidence was produced here to support such findings and establish definitive umbilical artery Doppler patterns as a prognostic factor.
