Mediastinal collateral arteries are usually present in children with coarctation of the aorta or obstruction of the subclavian artery. These arteries, normally bilateral, connect the subclavian artery, costocervical trunk, or supreme intercostal artery to the descending thoracic aorta. They probably represent hypertrophied preexisting normal vessels of an embryologic origin other than persistence of a dorsal aortic root. Radiologists should be aware of the high frequency of these mediastinal vessels in patients with coarctation of the aorta and subclavian obstruction because they indicate a hemodynamically significant lesion.
纵隔侧支动脉通常存在于患有主动脉缩窄或锁骨下动脉梗阻的儿童中。这些动脉通常为双侧，连接锁骨下动脉、肋颈干或最上肋间动脉与胸降主动脉。它们可能代表了胚胎起源的、预先存在的正常血管肥大，而非背主动脉根部的持续存在。放射科医生应意识到这些纵隔血管在主动脉缩窄和锁骨下动脉梗阻患者中的高发生率，因为它们提示了具有血流动力学意义的病变。
