A tubular
aortopulmonary window: An embryological curiosity.
4D CT revealed single solid lesion in the left thyroid and 2 solid lesions in the
aortopulmonary window, suggestive of parathyroid nodes.
It consists of creating an
aortopulmonary window and the flow between the RCA ostium and the aorta is established using an intrapulmonary tunnel [8, 14, 15].
Contrast enhancement chest CT, performed in the portal venous phase as our usual staging protocol, reveals that the left upper pulmonary vein presents an anomalous route: it first runs under the left pulmonary artery, then goes up medially to it, runs via the
aortopulmonary window, and finally joins the left brachiocephalic vein, describing on the whole a curved line with superior concavity (Figures 1 and 3).
Most cases of type B were actually
aortopulmonary window defects, and as such type B classification is no longer used [4].
Aortopulmonary window with severe nonreactive pulmonary hypertension
Closure of nonrestrictive
aortopulmonary window in an infant by the transcatheter approach.
The
aortopulmonary window is filled in, and there is peripheral pruning suggestive of pulmonary hypertension.
Aortopulmonary window lymph nodes were negative for tumor.
ARCAPA may be associated with other congenital and acquired heart diseases, including
aortopulmonary window, truncus arteriosus, anomalous subclavian artery, tetralogy of Fallot, constrictive pericarditis, bicuspid aortic valve, and mitral regurgitation [7, 9-15].
Some reports have found its association with tetralogy of Fallot, complete atrioventricular septal defect, and
aortopulmonary window, which arises secondary to failure of septation in the aorticopulmonary trunk.
Aortopulmonary window (APW) is a relatively rare congenital disease consisting of a septal defect between the ascending aorta and the pulmonary artery, creating a left-to-right shunt (1-4).
