Aneurysm of the ductus arteriosus may be either spontaneous or acquired as a complication of surgical closure of a patent duct. Patients may be asymptomatic or present with a wide spectrum of symptoms, including hoarseness, respiratory symptoms, aortic or pulmonary thrombosis or embolism, or rupture of the aneurysm. We present the first report of prenatal ultrasonographic diagnosis of isolated ductus arteriosus aneurysm. The aneurysm presented at 39 weeks as an enlarged, dilated, vascular structure 15 mm in diameter, which began at the bifurcation of the main pulmonary artery and ended in the descending aorta. Doppler imaging demonstrated turbulent flow in this lesion. Following spontaneous delivery, a bidirectional shunt in the ductus arteriosus was found on the 1st day, but the caliber of the vessel was normal. An almost completely functionally closed ductus was found on the 2nd day. Spontaneous resolution of the lesion was confirmed by magnetic resonance imaging at 4 weeks of age.
动脉导管瘤可能是自发形成的，也可能是作为动脉导管未闭手术闭合的并发症而获得的。患者可能无症状，或表现出各种各样的症状，包括声音嘶哑、呼吸道症状、主动脉或肺血栓形成或栓塞，或动脉瘤破裂。我们首次报告了产前超声诊断孤立性动脉导管瘤。该动脉瘤在孕39周时表现为一个直径15毫米的增大、扩张的血管结构，起始于主肺动脉分叉处，终止于降主动脉。多普勒成像显示该病变内有湍流。自然分娩后，出生第1天发现动脉导管存在双向分流，但血管口径正常。出生第2天发现动脉导管几乎完全功能性闭合。在4周龄时通过磁共振成像证实病变已自然消退。
