Of these, 51 patients required use of the 30\u00b0 fetoscope (study group) and 125 placental locations permitted use of the 0\u00b0 fetoscope (controls).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The two groups had very similar outcomes. The median gestational age at FLC in the study group vs. control group was 21.0 (range, 17.4\u201324.6) weeks vs. 20.6 (range, 15.9\u201324.6) weeks. Both fetuses survived in 58.8% (30\/51) of study patients vs. 66.4% (83\/125) of controls. At least one fetus survived in 84.3% (43\/51) of study patients and 88.8% (111\/125) of controls (<jats:italic>P<\/jats:italic> = 0.45). Study patients delivered at a median of 34.1 (range, 25.0\u201338.4) weeks and controls at 34.0 (range, 25.0\u201340.3) weeks' gestation.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Use of a 30\u00b0 fetoscope for FLC in cases of technically challenging extensive anterior placentation is associated with an outcome that is very similar to that achieved when a 0\u00b0 fetoscope is used in cases of more favorable placental location.
