Final answer:
Untreated Twin-Twin Transfusion Syndrome can result in serious consequences for both the recipient and donor twins, with the recipient twin at risk of developing the life-threatening condition hydrops fetalis.
Step-by-step explanation:
Twin-Twin Transfusion Syndrome (TTTS) is a condition that can occur in identical twins who share a placenta. In this condition, the blood flow between the twins is unbalanced, with one twin (the donor twin) giving too much blood to the other twin (the recipient twin). If left untreated, TTTS can have serious consequences for both twins.
Outcomes in Untreated TTTS:
If TTTS is left untreated, the recipient twin is at risk of developing a condition called hydrops fetalis. Hydrops fetalis is characterized by an excessive accumulation of fluid in the body, leading to severe swelling and organ failure. It can be life-threatening for the recipient twin. The donor twin, on the other hand, may experience a decrease in blood volume, which can lead to growth restriction and other complications.
