INTRODUCTION
Monochorionic twin pregnancies, by virtue of vascular anastomoses, are at risk of unique complications. These include Twin-To-Twin Transfusion Syndrome (TTTS), Selective Intrauterine Growth Restriction (sIUGR), and Twin Reverse Arterial Perfusion (TRAP) sequence. Vascular anastomoses are present in every monochorionic placenta; these represent a state of imbalance in the shunting of blood, or an abnormality in the nature of anatomising vessels, which forms the basis for these unique clinical entities. The extreme circumstances of these complications eventually lead to single foetal demise in such twins. The intra-uterine demise of one fetus results in the acute transfer of intravascular volume from the co-twin to
