Previously, after the unsuccessful drug treatment, surgical ligation was the primary treatment option. However, according to clinical studies, the Amplatzer Piccolo Occluder was approved for PDA closure for patients \u2265700 g. In our country, percutaneous PDA embolization has not been performed yet. Case Presentation: We present three premature infants with hemodynamically significant patent ductus arteriosus (hsPDA) in whom percutaneous occlusion was performed using the Amplatzer Piccolo Occluder (APO). The average gestational week (GW) was 27 \u00b1 1, while body weight was 1030 \u00b1 60 g. All patients had respiratory deterioration, with dilatation of the left heart chambers, and renal failure. The second developed a severe form of broncho-pulmonary dysplasia. Transthoracic echocardiography (TTE) examinations revealed a hemodynamically significant PDA (LA\/Ao 1.8\u20132.2) and medical closure was unsuccessfully carried out. Due to the hemodynamically significant PDA maintenance in all neonates, transvenous PDA closure was performed using the APO (APO 9-PDAP-04-02-L, 9-PDAP-04-04-L, 9-PDAP-05-054L, respectively). The entire devices, with both retention discs, are implanted within the duct. TTE pointed out adequate device position without descending aorta, left pulmonary artery obstruction, residual shunt, and reverse remodelling of the left ventricle and left atrium. The first newborn was weaned from mechanical ventilation three days after the procedure and discharged three weeks after. The second patient was extubated 2 weeks after the procedure, and even the severe BPD, X-ray showed improvement. The third patient\u2019s renal failure completely resolved, weaned from inotropic drug support and mechanical ventilation. Conclusions: Due to a significantly lower complication rate than surgical ligation, we will strive to make percutaneous PDA occlusion a new standard for treatment in newborns, especially preterm newborns, in our country.<\/jats:p>","DOI":"10.3390\/reports8020097","type":"journal-article","created":{"date-parts":[[2025,6,18]],"date-time":"2025-06-18T05:30:42Z","timestamp":1750224642000},"page":"97","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["The First Percutaneous Closures of Patent Ductus Arteriosus in Premature Neonates in Serbia: A Case Report Series"],"prefix":"10.3390","volume":"8","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3007-5631","authenticated-orcid":false,"given":"Stasa","family":"Krasic","sequence":"first","affiliation":[{"name":"Cardiology Department, Mother and Child Health Institute of Serbia, 11070 Belgrade, Serbia"},{"name":"Faculty of Medicine, University of Belgrade, 11000 Belgrade, Serbia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Branislav","family":"Mojsic","sequence":"additional","affiliation":[{"name":"Anesthesiology Department, Mother and Child Health Institute of Serbia, 11070 Belgrade, Serbia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vladislav","family":"Vukomanovic","sequence":"additional","affiliation":[{"name":"Cardiology Department, Mother and Child Health Institute of Serbia, 11070 Belgrade, Serbia"},{"name":"Faculty of Medicine, University of Belgrade, 11000 Belgrade, Serbia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,6,18]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"e20201209","DOI":"10.1542\/peds.2020-1209","article-title":"Patent Ductus Arteriosus of the Preterm Infant","volume":"146","author":"Hamrick","year":"2020","journal-title":"Pediatrics"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"63","DOI":"10.1093\/pch\/pxab085","article-title":"Management of the patent ductus arteriosus in preterm infants","volume":"27","author":"Mitra","year":"2022","journal-title":"Paediatr.
