Study Design
This study was a retrospective chart review of all infants with a
diagnosis of chylothorax at Texas Children’s Hospital (TCH) who received
sirolimus as treatment between January 1st 2009 and
December 31st 2020. Institutional Review Board
approval was obtained through the Baylor College of Medicine prior to
undertaking this study. Informed consent and authorization were waived
as the chart review was completed retrospectively and no direct patient
contact was required for study completion.
