Isolated neonatal ductus arteriosus aneurysm

Abstract

There is a higher incidence of DAA with a good outcome in our series compared with previous reports. We speculate that the presence of DAA may be a normal variant of the ductal bump and part of a normal process of spontaneous ductal closure in full-term neonates.

Symptomatic aneurysm of ductus arteriosus in neonates

“…[4–7] It is rare for symptomatic DAA to manifest within 24 hours of birth,[23] and the symptoms are commonly due to complications like spontaneous rupture, thromboembolism, infection, erosion into airways, or compression of adjacent thoracic structures. [235–7] But in our series, all the four neonates had presented a few hours after birth with stridor and feeble cry on account of compression of adjacent thoracic structures by a large DAA; their giant size (maximum internal mean diameter of 15.9 ± 3.5 mm) probably is the reason for the early presentation. Although all four neonates presented with symptoms within 24 hours after birth, only one required surgery.…”

“…Thrombus formation was noted in 30% of cases in the series of Jan et al . [5] CT scan and magnetic resonance imaging (MRI) are useful tools to delineate the extent of DAA and degree of compression of the surrounding structures. [5] Two of the cases in our study group underwent CT scan of the thorax which demonstrated compression of left main bronchus in one and thrombus formation in the other.…”

“…In the initial 24–48 hours, a small eccentric jet producing left to right shunt was commonly demonstrable through the patent ductus arteriosus (PDA) [Figure 1]. The suprasternal and high parasternal views showed the typical echocardiographic features termed the “triple star sign”[5] constituted by the ductus aneurysm, the ascending aorta and the main pulmonary artery (PA) [Figure 2]. The maximum internal diameter of DAA ranged from 12.5 to 20 mm.…”

Pulmonary Stenosis Caused by Ductus Arteriosus Aneurysm: A Case Report

“…A ductus arteriosus aneurysm is a congenital cardiac abnormality with an 8.8% reported incidence among full-term neonates. 1 ) Ductus arteriosus aneurysms diagnosed in the neonatal period are often asymptomatic and have a benign natural course, resulting in spontaneous regression and disappearance in most cases. 1 , 2 ) Rarely, a ductus arteriosus aneurysm may present with symptoms requiring medical attention.…”

Reported symptoms include thromboembolism, infection, compression of an adjacent structure, and spontaneous rupture.…”
