Abstract: | Summary Cardiac catheterization was performed in nine patients with unilateral absence of a pulmonary artery. Aortography revealed
a diverticulum of the innominate artery in five of six patients in whom the aortic arch and absent pulmonary artery were on
opposite sides. It is suggested that the diverticulum indicates fetal systemic blood supply to the affected lung through the
distal part of the sixth aortic arch, which—consisting of ductal tissue—obliterated after birth, leaving the diverticulum
where the ductus joins the innominate artery. |
