Histologic examination of a pulmonary biopsy at two years of age and tissue obtained at autopsy at three years of age showed obstructive pulmonary vascular disease. The question as to whether the organic pulmonary vascular lesions are secondar...

OBJECTIVES To determine the case incidence of ductus arterious aneurysm among our neonates, and to report on our experience in the presentation, echocardiographic features, management and outcome of this condition. METHODS Retrospective review of cases diagnosed within a 1-year period from 1 July 1998 to 30 June 1999. RESULTS Eight cases of neonatal ductus arteriosus aneurysm (DAA) were dia...
