title: [A case of rapidly progressive pulmonary pulmonary hypertension in a 14-year-old girl].
abstract: A 14-year-old girl was admitted with chief complaints of edema and chest pain. She had hepatomegaly, but did not have heart murmur and accentuation of the pulmonary component of the second heart sound. The electrocardiogram showed right axis deviation, negative T wave in V3,4 and ST depression in III, aVF. But right ventricular hypertrophy was not dominant. Chest radiography showed a cardiothoracic ratio of 54% and a slight prominence of proximal pulmonary arteries. The edema was soon diminished only by the diuretics, but it appeared again without the diuretics. At the cardiac catheterization 3 months after the onset of symptoms, the pulmonary arterial pressure was 150/85 mmHg and the pulmonary resistance was 3,232 dyn/sec/cm5. The right atrial pressure was 9.5 mmHg and oxygen saturation at the pulmonary artery was 31.0%. Prostaglandin E1 reduced the pulmonary artery pressure only a little, but raised the systemic pressure. The patient was treated with several vasodilators, but her condition deteriorated rapidly and she developed severe right ventricular failure. She died only 8 months after the onset of symptoms and 5 months after the catheterization. At autopsy, histological examination demonstrated intimal fibrotic thickening of the small-sized pulmonary arteries and organizing thrombus. But there was not plexiform lesion. Heart failure was easily improved when she was first admitted. But after 3 months the cardiac catheterization revealed that her condition was already severe. Several vasodilators was not effective to such a rapidly progressive primary pulmonary hypertension.
