Alveolar capillary dysplasia and persistent pulmonary hypertension of the newborn
Abstract
Alveolar capillary dysplasia is a rare cause of persistent pulmonary hypertension of the newborn. The diagnosis of this condition is made by histological study of a pulmonary biopsy. Familial forms and associated genitor-urinary and gastrointestinal malformations have been reported. Despite optimal management, the prognosis remains poor. The authors report the case of a neonate who developed cyanosis and cardiogenic shock on the 10th day of life. There was no associated neonatal pathology. Echocardiography showed supra-systemic pulmonary hypertension with normal cardiac structure. Pulmonary vasodilator therapies (inhaled NO, prostacyclin, sildenafil, bosentan) were ineffective and the child died on the 25th day of life. Autopsy revealed alveolar capillary dysplasia.
How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
