“…Selective intrauterine growth restrictions (sIUGR) occurs in about 12% of twin pregnancies (Sebire et al, 1997;Gaziano et al, 2000;Gratacos et al, 2004), an incidence rate similar to dichorionic and monochorionic pregnancies (Gratacos et al, 2004). Monochorionic twins with sIUGR have a higher incidence of respiratory and neurological complications than dichorionic pregnancies (Gonzalez- Quintero et al, 2003;Fick et al, 2006;Costa-Rojas et al, 2007).…”

Objective: To investigate whether perioperative fetal hemodynamic changes in twinto-twin transfusion syndrome (TTTS) are associated with neurodevelopmental impairment (NDI) at two years.Methods: Doppler parameters of three sonograms (day before, first day after and 1 week after laser surgery for TTTS) were assessed for correlation with neurodevelopmental outcome at two years (2008)(2009)(2010)(2011)(2012)(2013)(2014)(2015)(2016). NDI was defined as: cerebral palsy, deafness, blindness, and/or a Bayley-III cognitive/motor developmental testscore > 2SD below the mean.Results: Long-term outcome was assessed in 492 TTTS survivors. NDI was present in 5% (24/492). After adjustment for severe cerebral injury (present in 4%), associated with NDI were: middle cerebral artery peak systolic velocity (MCA-PSV) >1.5 multiples of the median (MoM) 1 day after surgery (odds ratio [OR] 4.96; 95% confidence interval [CI]:1.17-21.05, P = .03), a change from normal umbilical artery pulsatility index (UA-PI) presurgery to UA-PI >p95 postsurgery (OR 4.19; 95% CI: 1.04-16.87, P = .04), a change from normal to MCA-PSV >1.5MoM (OR 4.75; 95% CI: 1.43-15.77, P = .01). Conclusion: Perioperative fetal hemodynamic changes in TTTS pregnancies treated with laser are associated with poor neurodevelopmental outcome. Prospective research on the cerebrovascular response to altered hemodynamic conditions is necessary to further understand the cerebral autoregulatory capacity of the fetus in relation to neurodevelopmental outcome.

“…Beyond the 20th week of gestation even normal twin fetuses may show smaller biometric measurements than singletons and, therefore, specially adapted growth curves should be used. 16 Doppler assessment of the fetal circulation may help to distinguish between these two conditions. In small-for-gestational age fetuses, the benefits of Doppler ultrasound should be used.…”
