Major causes of pulmonary hypertension in children
What are some of the major causes of pediatric pulmonary hypertension, and what are the major associated CT features?
Causes of pediatric pulmonary hypertension may include: chronic lung disease of prematurity, CHD, sickle cell disease, chronic pulmonary emboli, and causes of left-sided heart failure (such as pulmonary vein stenosis). Findings on CT include: right ventricular hypertrophy, enlargement of the main pulmonary artery (greater in caliber than the ascending aorta at the same level), and flattening or bowing of the interventricular septum toward the left ventricle.
