Associated malformation and prognosis of AOPA.
| Case | Gestational age (weeks) | Affected PA | Associated with intracardiac malformations | Outcome | Characteristics of the case |
|---|---|---|---|---|---|
| 1 | 25+4 | R | / | Termination, dissection | / |
| 2 | 23+6 | R | / | Termination, dissection | / |
| 3 | 24+6 | L | TOF, right aortic arch with mirrored branches, left innominate vein under the aortic arch | Termination, dissection | The left pulmonary artery emanated from the left side of the aortic root and crossed with the right pulmonary artery to the left lung |
| 4 | 35+4 | R | VSD | Termination, dissection | / |
| 5 | 24+2 | R | Dexiocardia, CoA, IAA, VSD, MA, tricuspid valve dysplasia with severe regurgitation | Termination, dissection | Associated with multiple intracardiac malformations and missed diagnosis in the outer hospital |
| 6 | 23+5 | R | / | Full-term delivery, Apgar 10′. The child is currently 5 years old and has not undergone any treatment | The initial part of the right pulmonary artery originating from the ascending aorta was narrowed and progressively developed into atresia |
| 7 | 23 | R | APW, IAA | Termination, dissection | / |
| 8 | 24+3 | R | Slightly thinner aortic isthmus | Cesarean section at 32 weeks, Apgar 8′. The child is currently 1+ month old and is still being followed | One of the twins of the monochorionic double amniotic sac. The initial part of the right pulmonary artery was narrowed and progressively developed into atresia |
AOPA, anomalous origin of unilateral pulmonary artery; LINV, left innominate vein; VSD, ventricular septal defect; CoA, coarctation of the aorta; IAA, interruption of the aortic arch; MA, mitral atresia; APW aortopulmonary window.
