Aortotomy site infections: case presentation and review of the literature.
A patient with Aspergillus fumigatus infection involving an aortotomy site with multiple peripheral emboli following implantation of an aortic valve prosthesis for rheumatic heart disease is described. Eleven aortotomy site infections are reviewed from the literature. Eight cases were caused by fungi with Aspergillus sp accounting for four cases. Presenting symptoms were nondiagnostic and multiple. However, the diagnosis of aortotomy site infection should be entertained in patients who have had aortic valve surgery who develop fever and embolic phenomena with or without positive blood cultures coupled with no evidence of valve dysfunction, and who respond inappropriately to antibiotic therapy. Ten of the 11 patients reviewed from the literature died. Therapy should be directed at early recognition followed by prompt early surgery combined with the use of proper antimicrobial agents directed against the isolated microorganism.
