ABSTRACT
OBJECTIVE@#To study the clinical features and prognosis of bronchopulmonary dysplasia (BPD) complicated by pulmonary hypertension (PH) in preterm infants.@*METHODS@#A retrospective analysis was performed on the clinical data of 191 preterm infants with BPD.@*RESULTS@#In the 191 preterm infants with BPD, 37 (19.4%), all with moderate or severe BPD, developed PH beyond 36 weeks' corrected age. The incidence rates of PH in infants with moderate and severe BPD were 5.7% (5/87) and 47.8% (32/67) respectively. Gestational age and birth weight were lower in infants with PH than in those without PH (P<0.01). Infants with PH had higher incidence rates of small for gestational age (SGA), severe BPD, surgical ligation of patent ductus arteriosus (PDA), neonatal respiratory distress syndrome, hemodynamically significant PDA, and pneumonia than those without PH (P<0.01). Durations of oxygen therapy, intubation, and positive pressure ventilation were longer in infants with PH than in those without PH (P<0.01). Infants with PH had higher incidence rates of retinopathy of prematurity and extrauterine growth retardation, a higher mortality, and a longer length of hospital stay compared with those without PH (P<0.01). In the 37 infants with PH (6 with mild PH, 14 with moderate PH, and 17 with severe PH), those with mild or moderate PH all survived; 15(88%) out of 17 infants with severe PH died.@*CONCLUSIONS@#The incidence of PH is high in preterm infants with moderate or severe BPD. Regular screening of pulmonary artery pressure is recommended for infants with BPD. Infants with low gestational age and birth weight, SGA, and severe BPD are more likely to develop PH. Infants with BPD complicated by PH have relatively high incidence rates of complications, high mortality, and poor prognosis.
