MENDEZ, Lupo et al. Pulmonary sequestration an uncommon cause of persistent pulmonary hypertension in the newborn case report. Salud, Barranquilla [online]. 2017, vol.33, n.3, pp.532-537. ISSN 0120-5552.

Persistent pulmonary hypertension of the newborn (PPHN) is a common feature in neonatal intensive care units (NICUs), but some of its causes go unnoticed due to their low frequency and low association with this pathology. A case in our NICU, in a term neonate who presented PPHN secondary to a pulmonary malformation, rarely associated with this pathology in this age group, since it was found more disposition to factors of the birth, and maternal noxas. The patient presented respiratory difficulty hours after birth, with evolution and persistence of their symptoms, which required different diagnostic methods to establish their etiology. It is important to note that the first Doppler echocardiogram did not show any anatomical or functional alterations, which were normal; With subsequent clinical worsening of the neonate, so that an echocardiographic control is ordered, evidencing an estimated pulmonary pressure of 71 mmHg; The etiological study was followed with complementary images, in this case, a contrast-enhanced chest tomography, and finally it was corroborated with cardiac catheterization, allowing, in turn, therapeutic management and correction of structural abnormality of pulmonary vessels.
