Aim:
Patent Ductus Arteriosus is an important cause of morbidity and mortality in preterms. As birth weight decrease, risks increase. Main aim of our study is to emphasize the effectiveness and safety of percutaneous PDA closure even in extremely low birth infants.
Materials And Methods:
In our center between the dates June 2014-June 2016, PDA of 10 patients less than 1,000 gr were closed percutaneously. To the best of our knowledge this study includes the largest cohort of infants less than 1,000 g in the literature, that PDA of those were percutaneously closed.
Results:
Symptomatic patients, less than 1,000 gr having PDA were included in the study. All have 3 times medical therapy for PDA closure but it did not work. PDA was decided to be contributor of this medical state of them. The mean patient age was 19.5 ± 7.2 days. The median weight was 950 (842-983) gr. Mean gestational age was: 26.3 ± 0.63 weeks. Mean PDA diameter was 1.9 ± 0.41 mm. Morphology of PDA:6 of them were conical and 4 of them were tubular. In all patients ADOII-AS device were used for PDA closure via venous route. No major complications were reported. Left pulmonary arterial stenosis was detected in 1 patient who was resolved in 6 months duration.
Conclusion:
We want to emphasize that in experienced centers percutaneous closure of PDA can be an alternative to surgery even in the extremely low birth weight babies.
