We compared the two methods with respect to various demographic, obstetric and perinatal outcome variables.<\/jats:p><\/jats:sec>Results<\/jats:title>Fifty\u2010three selective terminations in complicated MC<\/jats:styled-content> twin gestations were performed, 36 by RFA<\/jats:styled-content> and 17 by BPC<\/jats:styled-content>. Each technique resulted in a similar overall survival rate of the remaining twin (88.9% vs<\/jats:italic> 76.5%, P<\/jats:italic>\u2009=\u20090.25). Likewise, the mean procedure\u2010to\u2010delivery interval, the rate of spontaneous preterm delivery <\u200937, <\u200934, <\u200932 and\u2009<\u200928 weeks and the rate of preterm prelabor rupture of the membranes did not differ between the groups. However, among patients in the BPC<\/jats:styled-content> group, there was a trend towards earlier gestational age at delivery (31.3 vs<\/jats:italic> 35.0\u2009weeks, P<\/jats:italic>\u2009=\u20090.09) compared with in the RFA<\/jats:styled-content> group. There was selective reduction by RFA<\/jats:styled-content> due to selective intrauterine growth restriction (sIUGR<\/jats:styled-content>) in 19 cases, 17 (89.5%) of which survived perinatally, with delivery at a median gestational age of 37 weeks. There were no significant differences in perinatal outcome, irrespective of whether the procedure was performed pre\u2010 or post\u2010viability. All post\u2010viability reductions, most of which were by RFA<\/jats:styled-content>, resulted in perinatal survival.<\/jats:p><\/jats:sec>Conclusions<\/jats:title>Perinatal outcome of complicated MC<\/jats:styled-content> twin gestations undergoing selective feticide seems to be similar regardless of whether termination is by BPC<\/jats:styled-content> or RFA<\/jats:styled-content>. Nevertheless, RFA<\/jats:styled-content> appears to be particularly useful in MC<\/jats:styled-content> twins complicated by sIUGR<\/jats:styled-content> and in cases requiring selective reduction beyond the age of viability.
