Case Reports
Salmonella reinfection manifesting as a fistula between the duodenum and an aortic stump pseudoaneurysm.
Despite the worldwide increase in Salmonella infections, a Salmonella infection of an aortic graft is an exceptional event. A Salmonella reinfection manifesting as a fistula between the duodenum and an aortic stump pseudoaneurysm 30 months after prosthetic excision, aortic ligature and extra-anatomic bypass for a Salmonella graft infection is a unique event. This unusual late complication described in this case report developed in 1 of the 5 patients whose Salmonella aortic graft infections have been previously reported. The reinfection causing septic aortitis responded to conventional surgery.

A 45-year-old man presented with deep vein thrombosis of the right leg and bilateral pulmonary embolism. Heparin was administered on the initial one and a half days. On the 3rd day, an inferior vena cava (IVC) filter was placed with a heparin flush, after which massive IVC thrombosis developed. ⋯ The platelet count increased to 355000/mm3 on the 15th day. The patient was positive for antibody against complexes of heparin and platelet factor 4, and was diagnosed as heparin-induced thrombocytopenia with thrombosis syndrome (HITTS). When thrombosis develops during heparin treatment, it is important to suspect HITTs and to assay for the associated antibodies, regardless of the actual platelet count.
