Prenatal diagnosis of ductus arteriosus aneurysm

Abstract

The ductus arteriosus holds major functional importance within the fetal circulation, and anomalies within the ductus arteriosus may interfere with the integrity of the fetal circulation. Ductus arteriosus aneurysm, previously considered a rare lesion, is now a well-reported finding in infancy with some reports describing this finding in the prenatal period. Postnatally, most ductus arteriosus aneurysms resolve spontaneously; however, a small group of infants show complications such as connective-tissue disorders, thrombo-embolism, compression of surrounding thoracic structures and life-threatening spontaneous rupture requiring surgical correction. As such, postnatal assessment in this group is recommended.

Prenatal Diagnosis of Ductus Arteriosus Aneurysm: A Case Report and Literature Review

“…The pregnancy was uneventful, and the infant was asymptomatic after birth. The DAA had spontaneously resolved without complications around the third week after delivery 9]. Similar to report, the DAA was diagnosed prenatally in the third trimester, and the fetus was asymptomatic with an uncomplicated pregnancy.…”

Multiple vascular malformations in a newborn

“…Although the renal duplication and dual renal arteries are not typically seen in the disorder, it is possible that they may be a previously undescribed component. The DAA has also been reported as an isolated finding [ 12 ]. To date, no specific genetic abnormalities have been identified, but the multiplicity of anomalies suggests the possibility.…”
