Abstract
BACKGROUND: This is a report on percutaneous closure of patent ductus arteriosus (PDA) using Amplatzer Duct Occluder type two additional sizes (ADO II AS) in patients under 6 kg. METHODS: Prospective data were collected and a review of Patients' records was conducted. Demographics, and angiographic and clinical outcomes are reported in this article. RESULTS: During the period June 2011 to June 2017, of the 92 patients who underwent closure of the PDA using the ADO II AS device, 59 were under 6 kg. The median weight of the cohort at closure was 3.6 kg (range: 900 g - 5.8 kg). The median ductal diameter was 1.9 mm (range: 1.0-3.4 mm). Three embolisations in the cohort were all retrieved percutaneously. Two PDAs were closed percutaneously and one surgically. Four premature infants required blood transfusions. The closure rate was 96.6% before discharge. CONCLUSIONS: PDA closure using ADO II AS in small infants is feasible, effective and has few complications.
