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.
对9例单侧肺动脉缺如的患者进行了心导管检查。血管造影显示,在主动脉弓与缺如肺动脉位于相反侧的6例患者中,有5例无名动脉存在憩室。提示该憩室表明胎儿期通过第六主动脉弓远端向患侧肺提供体循环血液供应,第六主动脉弓远端由导管组织构成,出生后闭塞,在导管与无名动脉连接处留下憩室。
