[Primary aldosteronism. A risk factor for aortic dissection?].

Aortic dissection is a rare but severe disease. Numerous risk factors have been reported, all leading to an alteration of arterial structures, particularly extracellular matrix. Aortic dissection is a complication of arterial hypertension, whatever its origin. Primary aldosteronism, frequent cause of secondary arterial hypertension, is associated with arterial structural alterations, indirectly by a pressure factor, and directly by aldosterone, which modifies collagen contents and elastin/collagen ratios. In addition to the three previously reported cases, the three cases reported in the present paper lead to the hypothesis of a causal relationship between aldosteronism and aortic dissection. The need for hypertension screening and diagnosis of its potential causes, namely primary aldosteronism, is highlighted.
