Twin Twin Transfusion Syndrome
Renal Artery Dopplers in Twin Twin Transfusion Syndrome
Twin-twin transfusion syndrome (TTTS) is a complication affecting 10-15% of monochorionic, diamniotic (MCDA) twin pregnancies. Unevenly distributed blood flow across a shared placental circulation results in a volume-restricted…
