Abstract

A 25 year-old pregnant woman (G2P1) was diagnosed with fetal ductus arteriosus aneurysm (DAA) at 38 weeks of gestation. Patients have been referred to our hospital with the diagnosis of oligohydramnios. The three-vessel view of the heart and the sagittal view of the ductal arch showed a 12-mm fusiform dilatation of the ductus arteriosus. Turbulent flow was detected in it by color Obstetrics Doppler. DAA was confirmed by postnatal fetal echocardiography. Congenital DAA, usually developed in the third trimester, is potentially fatal due to the possible complications such as spontaneous rupture, dissection, and thromboembolism.
