Severe portopulmonary hypertension in congenital hepatic fibrosis

Portopulmonary hypertension is a rare complication of portal hypertension. Although epoprostenol infusion, nitric oxide inhalation, isosorbide-5-mononitrate, nitroglycerin, and calcium channel blockers may reduce pulmonary artery pressure in patients with portopulmonary hypertension, the prognosis remains poor. We present a case of congenital hepatic fibrosis associated with pulmonary hypertension. A 42-year-old man with congenital hepatic fibrosis visited our hospital with syncope. The man had suffered from breathlessness on exertion for 2 weeks before the episode of syncope. He also had a history of portal hypertension with documented gastric cardiac varices at the age of 28 years. Despite undergoing intensive care, the patient died 1 week after admission owing to severe right-sided heart failure. Autopsy revealed dilatation of the right atrium and right ventricle grossly and plexogenic pulmonary arteriopathy microscopically. Accurate diagnosis of portopulmonary hypertension requires awareness of the disease and a high index of suspicion when examining patients with portal hypertension and dyspnea.
