Localizing intrapulmonary shunt in hepatopulmonary syndrome by transesophageal echocardiography

Transesophageal echocardiography combining with peripheral injection of agi tated saline solution is a useful diagnostic tool to detect the intrapulmon ary shunt.(1,2)) We performed transesophageal contrast echocardiography in a case of hepatopulmonary syndrome with normal pulmonary angiography to def ine the intrapulmonary right-to-left shunt bilaterally.
