[Association of primary pulmonary hypertension and portal hypertension. Review of the literature and description of 2 further cases].

Previous studies have shown that the association between primary pulmonary hypertension and portal hypertension is not merely coincidental. Pathogenesis of this rare combination is unclear, and several hypotheses have been advanced. In the present article, we reviewed the literature on this topic. Two new cases of this syndrome, recently admitted to our hospital, are described. Clinical and laboratory findings of our patients agree with data of the previous case reports.
