Abstract

Background: The arterial switch operation (ASO) is the preferred surgical procedure used to correct dextro-transposition of the great arteries. A known complication of the ASO is branch pulmonary arteries (PAs) stenosis, which may require reintervention. Our goal is to determine the frequency of reintervention after the ASO and any factors associated with reintervention.

Methods: This was a single center, retrospective study of infants who underwent the ASO from June 6, 2011 to February 21, 2021. The primary outcome was the prevalence of reintervention on the PAs following the ASO.

Results: Sixty-eight infants were analyzed; 9 (13%) patients had 10 reinterventions. The mean age at time of the ASO was 6.52 ± 6.63 days; weight was 3.34 ± 0.57 kg. Those with a reintervention had a longer bypass time (P = .047). Mean age at reintervention was 0.80 ± 0.72 years; mean time from the ASO to reintervention was 0.799 ± 0.717 years. Six surgical procedures, two stent placements, and four balloon angioplasties were performed on a total of 13 branch PAs. There was no increased risk for reintervention on the right versus left PA. After reintervention, there was an improvement in the minimal PA diameter and echo gradient. There were no adverse events or mortality related to the reintervention. Mean follow-up was 6.17 ± 2.94 years.

Conclusion: The prevalence of branch PA reintervention following the ASO in our cohort was 13%. There is an association between longer cardiopulmonary bypass time and reintervention. After reintervention, there was an increase in PA diameter and a decrease in echo gradient.

动脉转换手术后肺动脉分支再介入的发生率
背景:动脉转换手术(ASO)是用于矫正大动脉右移的首选手术方法。ASO的一个已知并发症是肺动脉分支(PA)狭窄,可能需要再次介入治疗。我们的目标是确定 ASO 后再次介入的频率以及与再次介入相关的任何因素:这是对 2011 年 6 月 6 日至 2021 年 2 月 21 日期间接受 ASO 的婴儿进行的一项单中心回顾性研究。主要结果是ASO后再次干预PA的发生率:对 68 名婴儿进行了分析;9 名(13%)患者进行了 10 次再干预。ASO时的平均年龄为(6.52 ± 6.63)天;体重为(3.34 ± 0.57)公斤。再次干预的患者旁路时间更长(P = .047)。再次介入时的平均年龄为(0.80 ± 0.72)岁;从ASO到再次介入的平均时间为(0.799 ± 0.717)年。共对 13 个 PA 分支进行了 6 次手术、2 次支架植入和 4 次球囊血管成形术。与左侧 PA 相比,右侧 PA 再次介入的风险并没有增加。再次介入后,PA 的最小直径和回声梯度均有所改善。没有发生与再介入相关的不良事件或死亡。平均随访时间为(6.17 ± 2.94)年:结论:在我们的队列中,ASO 后再介入 PA 分支的发生率为 13%。心肺旁路时间延长与再介入之间存在关联。再介入后,PA 直径增大,回声梯度减小。
