It has not been described in the West African Medical literature. A case was recorded in a twin delivery at the labour ward four years ago in the same hospital but the underlying diagnosis was not made.
Objective: To describe a rare case of twin reversed arterial perfusion sequence occurring in a triplet pregnancy and review the current literature.
Methods: A case was evaluated at the delivery ward,Department of Obstetrics and the Neonatal unit of the Korle Bu Teaching Hospital upon information from the obstetric team that a monster had been born from a triplet set. Full documentation was done.
Results: The case documented was a twin reversed arterial perfusion sequence in a triplet pregnancy.
Conclusion: This rare condition has been well characterized and Obstetricians and Paediatricians should now be able to make an accurate diagnosis.
