PULMONARY-HYPERTENSION ASSOCIATED WITH PO RTAL-HYPERTENSION - 2 CASESREPORTS

The authors report the cases of two patients with pulmonary hypertensi on associated with portal hypertension. This is a rare association wit h a reported prevalence ranging from 0.25 to 0.73 %. The diagnosis of portal hypertension preceded that of pulmonary hypertension by several years. The physiopathological mechanism of the latter is not well kno wn although several hypotheses have been proposed. Treatment is only s ymptomatic. The prognosis is usually poor, the causes of death being r elated to complications of liver failure and/or portal hypertension or to those of pulmonary hypertension.
