Аннотация
Six cases of cyanosis and digital clubbing caused by liver cirrhosis were reported. The mean levels of PaO2 and PaCO2 were 6.4 +/- 0.8 kPa (48.3 +/- 6.2 mmHg) and 3.9 +/- 0.8 kPa (29.5 +/- 6.1 mmHg) respectively. The cause of cyanosis and digital clubbing in liver cirrhosis was discussed. Abnormal intrapulmonary shunting (IPS), which was proved in 4 cases by whole-body radionuclide scanning with 99mTc-MAA, is suggested as the major cause of cyanosis in liver cirrhosis. Clinically IPS is usually associated with debilitating conditions characterized by hyperventilation, abnormality of lung diffusion and orthodeoxia or platypnea. The authors suggest that whole-body radionuclide scanning with 99mTc-MAA may be performed for establishing IPS if liver cirrhosis is highly suspected to be the cause of severe hypoxemia.
