The causes and risk factors of symptomatic spontaneous pneumothorax in term newborns are not completely understood. In the present study, our aim was to investigate the risk factors for and clinical and laboratory characteristics of term newborns with spontaneous symptomatic pneumothorax and to evaluate the outcome of management in this condition. A total of 11 term newborns admitted to the newborn intensive care unit with a diagnosis of symptomatic spontaneous pneumothorax were included during a 22-month period. Female to male ratio was 4:7, mean gestational age was 39.5 weeks, and 63% were delivered with a cesarean section, 18% of patients had renal and 55% had congenital cardiac anomalies. Rate of cardiac anomalies was more frequent in the study group compared to control group. Echocardiography in addition to renal ultrasonography may also be needed in term newborns with spontaneous symptomatic pneumothorax and further studies may be warranted to evaluate this association.
Diameters of thoracic vascular structures increase with age. The consistent vertebral to vessel ratios can be useful in evaluation of chest CT of pediatric patients.
