Abstract

 

Aim: Bovine jugular vein graft is one of the conduits used in the reconstruction of the right ventricular outflow tract obstructions. It is frequently preferred since it is easy to provide, and the graftis available in different sizes and easy to manipulate. In some cases late term aneurysmal dilatation may occur.

Material and method: 9 year-old boy had a history of complete repair of tetralogy of Fallot, including closure of ventricular septal defect and placement of an 18-mm Contegra conduit between the right ventricle and pulmonary artery. In the fourth postoperative year, a routine follow up echocardiography showed increase of right ventricle pressure also severe pulmonary valve insufficiency and gradient across the valve was detected. An aneurysmatic dilatation was detected at the Magnetic Resonance angiography examination.

Conclusions: The aim of this report is to present our experience with this late term complication and to provide some suggestions to avoid this unfavorable outcome.
