| The ductus arteriosus usually closes within 24 hours of birth and is obliterated anatomically in 1-8 weeks. |
| The duct contained in the ring joins the ductus pancreaticus near the duodenum. |
| These anomalies include patent ductus arteriosus, vascular ring, and coarctation of aorta. |
| Before birth, a large artery called the ductus arteriosus lets the blood bypass the lungs because the fetus gets its oxygen through the placenta. |
| The UVC courses from umbilical vein to left portal vein to ductus venosus to either hepatic vein or IVC and then into right atrium. |
| In most centres, surgical ligation is reserved for instances where the ductus remains open despite pharmacological treatment. |
