The effect of sildenafil on pleural and peritoneal effusions after the TCPC operation.

Background: We evaluated whether the administration of sildenafil in children undergoing the TCPC operation shortened the interval from the operation to the removal of the pleural and peritoneal drains.

Methods: We retrospectively reviewed the data of 122 patients who had undergone the TCPC operation between 2004 and 2014. Patients were divided into two groups on the basis of their treatments.
