The ductus arteriosus holds major functional importance within the fetal circulation, and anomalies within the ductus arteriosus may interfere with the integrity of the fetal circulation. Ductus arteriosus aneurysm, previously considered a rare lesion, is now a well-reported finding in infancy with some reports describing this finding in the prenatal period. Postnatally, most ductus arteriosus aneurysms resolve spontaneously; however, a small group of infants show complications such as connective-tissue disorders, thrombo-embolism, compression of surrounding thoracic structures and life-threatening spontaneous rupture requiring surgical correction. As such, postnatal assessment in this group is recommended.
动脉导管在胎儿循环中具有重要的功能意义，动脉导管的异常可能会干扰胎儿循环的完整性。动脉导管瘤以前被认为是一种罕见的病变，现在在婴儿期是一种报道较多的发现，一些报告描述了在胎儿期的这一发现。出生后，大多数动脉导管瘤会自发消退；然而，一小部分婴儿会出现并发症，如结缔组织疾病、血栓栓塞、周围胸部结构受压以及危及生命的自发破裂，需要手术矫正。因此，建议对这组婴儿进行出生后评估。
