非梗阻性先天性主动脉弓畸形的增强MR血管造影和心血管造影诊断

目的 报道115例非梗阻性先天性主动脉弓畸形，评估心血管造影和增强磁共振血管造影术（CE MRA）等影像诊断方法的价值。方法 115例先天性主动脉弓畸形单经心血管造影诊断106例，单经CE MRA诊断2例，经上述2种方法诊断7例。结果 115例中，双主动脉弓5例，右位主动脉弓迷走左锁骨下动脉45例，左位主动脉弓迷走右锁肌下动脉33例，右弓孤立左锁骨下动脉11例，右弓左降7例，左弓右降4例，颈主动脉弓4例，其他6例。7例同时做了心血管造影与CE MRA检查的患者2种方法诊断结果均相互符合。2例只做了MRA的病例中有1例为颈主动脉弓，另1例为右位主动脉弓迷走左锁骨下动脉。结论 造影增强MRA是可靠的非创伤性诊断手段。

Congenital aortic arch anomalies: contrast enhancement MRA and DSA diagnosis

Objective To report 115 cases of congenital aortic arch anomalies, and to evaluate the imaging diagnostic techniques. Methods One hundred and fifteen patients with congenital aortic arch anomalies underwent angiocardiography and(or)contrast enhancement magnetic resonance angiography (CE MRA). Results In this 115 cases, double aortic arch was seen in 5 cases, right aortic arch with aberrant left subclavian artery in 45 with isolated left subclavian artery in 11, left aortic arch with aberrant right subclavian artery in 33, right aortic arch with left descending aorta in 7, left aortic arch with right descending aorta in 4, cervical aorta in 4, and others in 6. Conclusion CE MRA is a reliable noninvasive imaging diagnostic method.
