Letter: Frequency of Hepatopulmonary Syndrome (HPS) Among Patients With Liver Cirrhosis: A Letter to Editor

Dear editor, hepatopulmonary syndrome (hps) is a complication of liver disease. it is most frequently related to portal hypertension (with or without cirrhosis), although chronic liver disease of almost any etiology could be related to hps. moreover, some acute liver diseases are related to hps, such as ischemic hepatitis. hps can be diagnosed when the following disorders have been approved; liver disorder, impaired oxygenation, intrapulmonary vascular anomalies, referred to as intrapulmonary vascular dilatations (ipvds) and lack of intrinsic cardiopulmonary problem. hps patients finally develop dyspnea on exertion, at rest, or both, commonly after years of liver disease. dyspnea may be accompanied by pulmonary findings that are more specific for hps such as platypnea and orthodeoxia. the frequency of hepatopulmonary syndrome in patients with chronic liver disease is about 4 to 47% regarding the criteria of diagnosis and used methods. the current study evaluated the prevalence of this complication in patients with cirrhosis.
