Iatrogenic Narrowing of Inferior Vena Cava after Atrial Septal Defect Closure: The Role of Intraoperative Echocardiography

Abstract

ABSTRACT Single-patch closure of a superior sinus venosus atrial septal defect (SVASD) may be complicated with narrowing of inferior vena cava (IVC). If the pressure gradient across the narrowed portion of superior vena cava (SVC) exceeds 6 mm Hg, widening of SVC lumen is considered. No such guidelines are available in literature for narrowing of inferior vena cava in cardiac surgical patients. We describe an incident of inferior narrowing of inferior vena cava in a 10-year-old girl, who was operated for closure of an inferior type of ostium secundum ASD (OSASD). There was hepatic venous dilatation accompanied with gradient of 3 mm Hg at the junction of inferior vena cava and right atrium (RA). The cardiopulmonary bypass was reestablished and the surgical closure of the septal defect was revised to rectify the problem.
