- Patent Ductus Arteriosus: Facts
- Connects the proximal descending aorta, immediately distal to the origin of the left subclavian artery, with the proximal left pulmonary artery at the junction of the main pulmonary artery
- Closes functionally 18-24 hours after birth and anatomically at one month
- If it is patent after 3 months it is a PDA "Multidetector CT is an alternative tool helpful in establishing the primary diagnosis, defining anatomic landmarks and their relationships, and identifying associated cardiovascular anomalies. It is also an adjunct in the evaluation of complications during follow-up"

- If it is patent after 3 months it is a PDA "CT is feasible to assess lumen narrowing of pediatric vascular stents at a wide range of tube settings."
