title: [Primary pulmonary arterial hypertension. Effects of vasodilators apropos of a case with a pulmonary biopsy].
abstract: A patient with primary pulmonary artery hypertension diagnosed by pulmonary arterial catheterisation, angiography and lung biopsy was the subject of several therapeutic trials of vasodilators. The short term and long term results over the next four years were on the whole disappointing. The type of study protocole used is discussed, as are the risks and cost.
