Abstract

Perigraft seroma formation following insertion of polytetrafluoroethylene grafts in patients with congenital heart disease is a rare complication.1 These grafts are often used during the Norwood procedure for patients with hypoplastic left heart syndrome (HLHS). Traditionally, the modified Blalock–Taussig–Thomas shunt is used; however, recently there has been a shift toward using right ventricle-to-pulmonary artery (RV-PA) shunts because of their improved short-term mortality.2,3 Little is known about the occurrence or management of RV-PA shunt perigraft seromas. Here, we present 2 cases of giant mediastinal seroma following RV-PA shunt insertion during the Norwood procedure. The institutional review board or equivalent ethics committee of the Children's Healthcare of Atlanta approved the study protocol and publication of data (STUDY00001460, July 18, 2022). Patient written consent for the publication of the study data was waived by the institutional review board, as it was determined to be research not involving human subjects.
