However, in very small premature infants, aortic arch repair has a relatively high mortality and morbidity rate. Bailout stenting is an alternative method that can be performed safely and effectively with low morbidity.<\/jats:p>\n               <jats:p>We present a case of severe CoA in a premature baby, a monochorionic twin with selective intrauterine growth restriction. The patient was born at 31 weeks of gestation with a birth weight of 570\u2009g. Seven days following her birth, she experienced anuria due to critical neonatal isthmic CoA. She underwent a stent implantation procedure at term neonatal, weighing 590\u2009g. She had good dilatation of the coarcted segment with no complications. Follow-up at infancy showed no CoA recurrence. This is the world\u2019s smallest case of stenting for CoA.<\/jats:p>","DOI":"10.1136\/bcr-2023-255215","type":"journal-article","created":{"date-parts":[[2023,6,9]],"date-time":"2023-06-09T10:01:22Z","timestamp":1686304882000},"page":"e255215","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":2,"title":["Successful
