Abstract

Background: The arterial switch operation (ASO) is standard treatment for D-transposition of the great arteries, and neo-aortic dilation is common afterward. Its behavior during pregnancy remains uncertain, especially the risk of dissection.

Case: We describe a 30-year-old woman (G6P0A5) with neo-aortic dilation (44 mm) during her first pregnancy, which remained stable on beta blockers until an uncomplicated caesarean delivery. In her subsequent pregnancy, an initial measurement of 47 mm raised concern. Expert review highlighted the challenges of accurately measuring asymmetric neo-aortas post-ASO and confirmed that the neo-aorta was stable (43 mm). The pregnancy continued without complications under beta-blocker therapy.

Discussion: No neo-aortic dissections have been reported after ASO, and progression above 2 mm was reported only in a few (2/131). Preconception evaluation, standardized measurement techniques, and trimester-based surveillance are essential. Mode of delivery should be individualized; caesarean delivery may be reasonable when dilation exceeds 45 mm.

大动脉完全转位后妊娠期新主动脉根扩张。

背景：动脉转换手术（ASO）是大动脉d转位的标准治疗方法，术后新主动脉扩张很常见。其在怀孕期间的行为仍不确定，特别是剥离的风险。病例：我们描述了一名30岁的女性（G6P0A5）在第一次怀孕期间出现新主动脉扩张（44毫米），在使用受体阻滞剂后病情保持稳定，直到剖宫产。在她随后的怀孕中，最初测量的47毫米引起了关注。专家评论强调了aso后准确测量不对称新主动脉的挑战，并确认新主动脉稳定（43 mm）。在受体阻滞剂治疗下，妊娠持续无并发症。讨论：ASO后没有新主动脉夹层的报道，只有少数（2/131）报告了超过2mm的进展。孕前评估、标准化测量技术和孕期监测至关重要。交付方式应个性化；剖宫产可能是合理的，当扩张超过45毫米。
