History And Admission Findings:
During evaluation for a liver transplantation in a 45-year-old man with alcoholic liver he complained of exertional dyspnea. He had grade 3 chronic obstructive pulmonary disease (COPD) after nicotine abuse of 50 pack-years. One and a half years earlier the patient had been treated for tuberculosis.
Investigations:
The diagnostic procedures showed a respiratory insufficiency with a PO(2) of 52 mm Hg. Notable was a missing improvement of oxygenation after the supply of 100 % oxygen. Lung perfusion scintigraphy showed a shunt of about 14 %, a contrast-medium echocardiography demonstrating a right-to-left shunt. These findings indicated that the patient had a hepatopulmonary syndrome.
Treatment And Course:
The only causal therapy of a hepatopulmonary syndrome was a liver transplantation. However, the tuberculosis diagnosed one and a half years earlier had not been treated adequately, so that an antituberculotic therapy was essential before starting an immunosuppression. Therefore the only option of treatment was to continue the long-term oxygen therapy. As a matter of differential diagnosis and because of the intrapulmonary shunt, a pulmonary venous disconnection for a shunt caused by tuberculous cavities or by the COPD had to be taken into account.
Conclusion:
Treating patients with advanced liver cirrhosis and dyspnea a hepatopulmonary syndrome must be taken into consideration. Typically there will be found a right-left-shunt. In addition, coexistent comorbidities as a reason for dyspnea have to be excluded.

Symptoms of COPD can be classified as primary or systemic. Primary symptoms relate to reduced airflow, while systemic or extrapulmonary symptoms relate to COPD's broader impact on the body.
