[A case of complex cardiac anomalies with high pulmonary blood flow treated successfully by PDA banding].
A patient with complex cardiac anomalies who developed severe respiratory insufficiency due to high pulmonary blood flow from a giant PDA was treated successfully by PDA banding. PDA-dependent heart disease causes a reduction in pulmonary blood flow in many patients and is often treated by palliative shunt operation. Although the present patient had PDA-dependent heart disease, heart failure occurred due to increased pulmonary blood flow through PDA and required surgical treatment. We performed PDA banding, because it is technically simple and allows adjustment of the postoperative pulmonary blood flow according to the degree of constriction. The degree of constriction was determined according to the PaO2 value. SO2 levels of 60-70% have been used as an index of the extent of banding, but PaO2 is considered to be equally appropriate.
