Successful repair of a contained rupture of mycotic aortic aneurysm in an 8-year-old child using polytetrafluoroethylene graft

Abstract

This study reports on a contained rupture of mycotic abdominal aortic aneurysm secondary to coagulase negative staph successfully repaired with aorto bi-iliac polytetrafluoroethylene (PTFE) Gor-Tex graft. An 8-year-old Saudi male patient was found to have infective endocarditis by coagulase negative staph with mitral valve (MV) leaflet damage, which was repaired with mechanical MV. Post-cardiac surgery, he complained of intermittent abdominal and back pain, until he became more symptomatic and had a sudden abdominal pain. Ultrasound showed abdominal aortic aneurysm (AAA), as well as the CT scan showed contained posterior rupture of AAA. He was operated immediately and the aorta was repaired with bifurcated PTFE Gor-Tex graft. He tolerated the operation, and he was given antibiotic coverage according to sensitivity. Tissue culture of the aorta confirmed coagulase negative staph. The strong relation between infective endocarditis and mycotic aneurysm should make a high index of suspicion of developing abdominal aortic aneurysm in children. Utilizing the PTFE graft with an omental patch is safe and life saving.
