Prenatal ductal constriction and closure usually are related to maternal intake of
prostaglandin receptor inhibitors during late gestation but may occur spontaneously. This …

Pathognomonic features of in utero premature restriction/closure of the ductus arteriosus
(DA) are increased right ventricular afterload, impaired right ventricular function, and …

Patency of the ductus arteriosus (DA) is maintained during gestation by locally produced
and circulating prostaglandins (PGE's). As gestation proceeds, the ductus becomes less …

OBJECTIVE: Closure of the fetal ductus arteriosus, which is usually due to nonsteroidal
antiinflammatory agents, may be detrimental. Therefore prenatal and postnatal clinical and …

Idiopathic intrauterine constriction/closure of the ductus arteriosus, which is distinct from that
secondary to maternal exposure to non-steroidal anti-inflammatory drugs, such as …

In utero isolated ductal closure is uncommon and can lead to fetal hydrops and death if not
recognized. Five fetuses were diagnosed prenatally by echocardiography. The reasons for …

Antenatal closure of the ductus arteriosus has been considered as a potential risk factor for
the development of hydrops fetalis and persistent fetal circulation of the newborn. We …

Constriction of the fetal ductus arteriosus in utero can be caused by pharmacological agents
or can occur spontaneously. The spontaneous constriction and closure of the ductus …

Antenatal stenosis or closure of the ductus arteriosus unrelated to either congenital heart
defects or prostaglandin inhibitors is considered to be uncommon, but may result in …

Objective. Prenatal constriction of the ductus arteriosus associated with maternal drug
ingestion was reported several decades ago. There are fewer reports of the complete …
