The angiocardiograms of 17 patients with aortic arch interruption are reviewed to emphasize the variations in arch interruption and origin of the brachiocephalic vessels, and collateral circulation to the descending aorta. Depending on the anatomical type and subtype of arch interruption, collateral flow to the descending aorta in the presence of a stenotic or closed ductus will be dependent on the development of intercostal collaterals and/or the presence of retrograde flow in all brachiocephalic vessels arising from the descending aorta. Familiarity with the potential pathways for collateral circulation may permit differentiation into types and subtypes on chest radiograph. Patients with Type I interruption may have bilateral rib notching if the right subclavian artery originates normally from the innominate artery, but will have rib notching confined to the left side if the origin of the right subclavian artery is aberrant. Type II or Type III interruption patients will have rib notching confined to the right side if the right subclavian has a normal origin, but no rib notching if the origin of the right subclavian artery is aberrant.
回顾了17例主动脉弓中断患者的心血管造影，以强调主动脉弓中断的变异、头臂血管的起源以及降主动脉的侧支循环。根据主动脉弓中断的解剖类型和亚型，在存在狭窄或闭合动脉导管的情况下，降主动脉的侧支血流将取决于肋间侧支的发育和/或所有发自降主动脉的头臂血管中逆行血流的存在。熟悉侧支循环的潜在途径可能有助于在胸部X线片上区分类型和亚型。I型中断的患者，如果右锁骨下动脉正常发自无名动脉，可能会出现双侧肋骨切迹，但如果右锁骨下动脉起源异常，则肋骨切迹仅限于左侧。II型或III型中断的患者，如果右锁骨下动脉起源正常，肋骨切迹将仅限于右侧，但如果右锁骨下动脉起源异常，则无肋骨切迹。
