Hepatopulmonary syndrome associated with autoimmune liver cirrhosis.
2001
A 46-year-old woman presented for evaluation of liver dysfunction and dyspnoea. Laboratory examination showed high levels of γ-globulin, immunoglobulin (Ig)G, and antinuclear antibodies. Laparoscopy demonstrated hepatic cirrhosis. Despite normal spirometry, hypoxaemia (which was worse in standing position) and a low diffusing capacity were present. The shunt ratio calculated using arterial blood gas was 6.4%, but was 40% when measured using 99mTc-macroaggregated albumin scanning. The discrepancy between the ratios indicated that hypoxaemia was caused by intrapulmonary vascular dilatation. The patient was diagnosed with hepatopulmonary syndrome associated with autoimmune liver cirrhosis.
