Transcatheter closure of patent ductus arteriosus in children weighing 10 kg or less: Initial experience at Sohag University Hospital

Aim: to assess the challenges,feasibility,and efficacy of device closure of patent ductus arteriosus (pda) in small children weighing ≤10 kg for different types of devices used in an initial experience at sohag university hospital. methods: between march 2011 and september 2014,91 patients with pda underwent transcatheter closure in our institute,among whom 54 weighed ≤10 kg. all of these patients underwent transcatheter closure of pda using either a cook detachable coil,pfm nit-occlud,or amplatzer duct occluder. a retrospective review of the treatment results and adverse events was performed. results: successful device placement was achieved in 53/54 small children (98.1%). the median minimum pda diameter was 2.4 mm [interquartile range (iqr,1.8-3.5 mm),median weight 8 kg (iqr,7-10 kg),and median age 10 months (iqr,8-17 months)]. mild aortic obstruction occurred in one case (1.9%),as the device became displaced towards the aorta after release. the device embolized in one case (1.9%) and no retrieval attempt was made. five cases (9.3%) had minor vascular complications. conclusion: with the current availability of devices for pda closure,transcatheter closure of pda is considered safe and efficacious in small children weighing ≤10 kg with good mid-term outcome. the procedure had a low rate of high-severity adverse events even with the initial experience of the catheterization laboratory. © 2015 the authors.
