The application of coarctation stenting has grown in paediatric and adult practice in recent years. Stent and delivery sheath technology has improved; however, we remain technically limited when implanting small calibre stents through small sheaths in small children, which then have the potential to be dilated to adult size as time passes. We describe the first reported use of the Valeo Biliary Pre-mounted Re-dilatable Stent (Edwards Life Sciences, California, USA) in aortic coarctation with 1 year follow-up including cross-sectional imaging. This 14 kg 3-year-old girl presented following an intracerebral haemorrhage secondary to severe systemic hypertension. Despite implantation through a 7-French sheath, this stent can be postdilated up to 20 mm, and therefore provides an important new addition to the interventional armamentarium.
近年来，缩窄支架植入术在儿科和成人临床实践中的应用有所增加。支架及输送鞘技术已有改进；然而，在通过小鞘管为小儿植入小口径支架时，我们在技术上仍存在限制，不过随着时间推移这些支架有可能扩张至成人尺寸。我们报告首例使用Valeo胆道预安装可再扩张支架（美国加利福尼亚州爱德华兹生命科学公司）治疗主动脉缩窄的病例，并进行了为期1年的随访，包括横断面成像。这名14公斤重的3岁女孩因严重系统性高血压继发脑出血前来就诊。尽管是通过7法国鞘管植入的，但该支架可后扩张至20毫米，因此为介入治疗器械库增添了一项重要的新设备。
