Key result
In a rare case of TRAP syndrome, a 38-year-old woman delivered a live donor twin vaginally at 26 weeks who survived after intensive care, while the acardiac twin required cesarean delivery.
Why the study?
Twin reversed arterial perfusion (TRAP) sequence is a rare and serious complication in monochorionic twin pregnancy that warrants description of diagnostic and delivery management.
Case Report (n=1)
This case highlights the complex obstetric management of TRAP syndrome, requiring emergency cesarean section for the acardiac twin following vaginal delivery of the pump twin due to severe bleeding.

Vaginal delivery may be viable for the donor twin in TRAP syndrome; leaves open prospective evaluation of perinatal outcomes.
Тwin reversed arterial perfusion (TRAP) sequence is a rare complication in monochorionic twin pregnancy. It is the most serious type of transfusion syndrome (ТТТS). One twin has serious malformations, and due to the fact that the heart is almost always missing, it is often called acardiacus. TRAP sequence is present in less than 1% of monochorionic pregnancies, while the incidence compared to normal pregnancies is one in 35,000 pregnancies. This paper presents the diagnostics, evaluation, and completion of pregnancy in a primipara with twin pregnancy complicated by the ТRAP syndrome.

Paunović et al. (2019) conducted a case report in Twin reversed arterial perfusion (TRAP) syndrome (n=1). Vaginal delivery and cesarean section was evaluated on Maternal and fetal survival. In a rare case of TRAP syndrome, a 38-year-old woman delivered a live donor twin vaginally at 26 weeks who survived after intensive care, while the acardiac twin required cesarean delivery.
