Journal ArticleDOI
Amniotic Fluid Water Dynamics
TL;DR: The study of amniotic fluid volume regulation may yield important insights into the mechanisms used by the fetus to maintain water homeostasis, and may allow novel treatments for amniotics fluid volume abnormalities with resultant improvement in clinical outcome.
Journal ArticleDOI
Regulation of amniotic fluid volume.
TL;DR: It is hypothesized that aquaporins have a role in regulating water flux across both the amnion and the placenta, and evidence is presented in support of this theory.
Journal ArticleDOI
Placental Characteristics of Monoamniotic Twin Pregnancies in Relation to Perinatal Outcome
K.E.A. Hack,M. J. C. Van Gemert,Enrico Lopriore,A.H.P. Schaap,Alex J. Eggink,Sjoerd G. Elias,J.P.H.M. van den Wijngaard,Frank P.H.A. Vandenbussche,Jan B. Derks,Gerard H. A. Visser,Peter G. J. Nikkels +10 more
TL;DR: The almost ubiquitous presence of compensating AA-anastomoses in MA placentas appears to prevent occurrence of TTTS, and perinatal mortality in MA twins was not related to placental vascular anatomy.
Journal ArticleDOI
Fetoscopic laser treatment of twin-to-twin transfusion syndrome followed by severe twin anemia-polycythemia sequence with spontaneous resolution.
Enrico Lopriore,Kurt Hecher,Frank P.H.A. Vandenbussche,J.P.H.M. van den Wijngaard,Frans J.C.M. Klumper,Dick Oepkes +5 more
TL;DR: A case of twin anemia-polycythemia sequence after laser surgery for twin-to-twin transfusion syndrome which resolved spontaneously is presented.
Journal ArticleDOI
Assessment of feto-fetal transfusion flow through placental arterio-venous anastomoses in a unique case of twin-to-twin transfusion syndrome.
Enrico Lopriore,J.P.H.M. van den Wijngaard,Johanna M. Middeldorp,Dick Oepkes,Frans J. Walther,M. J. C. Van Gemert,Frank P.H.A. Vandenbussche +6 more
TL;DR: Prospective measurements of decreasing haemoglobin levels between the intrauterine transfusion and birth allowed us to assess the net blood flow through the anastomoses as 27.9mL/24h, which may explain the inaccuracy of Doppler flow measurements.
