[Aneurysm of arterial duct associated to aortic arch interruption].
Aneurysm of the arterial duct is an infrequent finding, which is very rarely detected prenatally. A case of antenatal diagnosis in a pregnant patient (33 weeks) is reported. The fetus presented an aneurysmatic dilation of the arterial duct with uniformly enlarged diameter, inserting into the descending aorta, which was interrupted. The neonate was born by cesarean section and was kept on postaglandins till the 9th day of life, when he was sent to surgery. During the surgical procedure, the baby died as a result of biventricular failure. This is the first report of prenatal association of aneurysm of the ducts anteriosus with other cardiovascular malformations and emphasizes that this finding does not always have a benign course.
