Hepatopulmonary syndrome is characterized by hypoxemia induced by intrapulmonary vascular dilatations associated with hepatic diseases. We evaluated the frequency and case presentations revealed by general screening before liver transplantation. Sixty-one patients underwent arterial blood gas analysis in both upright and supine positions. Of these, 27 patients (44%) showed Pa02 <80 mmHg and AaD02 >15 mmHg, reflecting intrapulmonary shunting. Four patients exhibited Pa02 < 70 mmHg and orthodeoxia, defined as a fall in Pa02 >5% or 4 mmHg in an upright position. Finally, two patients showed hepatopulmonary syndrome, with positive findings on perfusion lung scanning. Both patients with hepatopulmonary syndrome had liver cirrhosis type C with habitual alcohol drinking and smoking. Potential pulmonary shunt patients with Pa02 < 80 mmHg and AaD02 >15 mmHg exhibited higher model for end-stage liver disease scores. Care should be taken regarding hepatopulmonary syndrome during liver cirrhosis management in Japanese patients.
