PP-05 Prenatal diagnosis of S-shaped ductus arteriosus

Objective

S-shaped ductus arteriosus is a variant, but cardiac function must be evaluated at 2-3 week intervals. In this case report; Prenatal diagnosis and management of S-shaped ductus arteriosus is discussed.

Case

The patient was referred to our clinic due to an abnormal view of the three-vessel trachea at 32 weeks. We identified an S-shaped ductus arteriosus, but there is no tricuspid valve regurgitation observed, and the right heart function appears normal.

Discussion

The DA can be classified as straight, mildly curved (C-shaped banding) markedly curved, or S-shaped . During middle gestation, percentage of S-shaped ductus arteriosus can increase.After 32 weeks, the S-shaped ductus arteriosus can cause tricuspid valve insufficiency and dysfunction of the right heart.

Conclusion

When an S-shaped ductus arteriosus is diagnosed, it is important to avoid using ductal constricting agents. S-shaped ductus arteriosus is a variant, but cardiac function must be evaluated at 2-3 week intervals.
