PDA varies according to gestational age and birth weight; it is more frequent among girls too. According to some series, about 30% of preterm infants with a birth weight below 1,500 g present a hemodynamically significant PDA (HS-PDA) in the first days of life.
Clinical course: On day 25 (D25) of life, a fluoroscopic exam confirmed the diagnosis of left hemidiaphragmatic paralysis. Due to the increase of the respiratory work despite support with NCPAP for 18 days and X-ray repetition, we decided to perform the plication. She had a good recovery after surgery and came out of respiratory support after 4 days. She was discharged off the NICU on D63. A comparative image showed the left hemidiaphragm in a neutral position. She maintains follow-up in Neonatology and Cardiology Outpatient Department, with a favourable clinical evolution.
