Diagnostic evaluation of hepatopulmonary syndrome in Egyptian children with chronic liver disease.

Unlabelled: There are few data on prevalence of hepatopulmonary syndrome (HPS) in children with chronic liver disease (CLD). This prospective study evaluated the prevalence and diagnostic procedures of HPS in Egyptian children with CLD. One hundred twenty (120) children with CLD were subjected to room-air pulse oximetry in supine and upright position, contrast enhanced echocardiography (CEE) and technetium-99m-labeled macroaggregated albumin (99mTc-MAA) perfusion lung scan.
