Abstract:
Infectious aneurysms are about 1-3% of all aneurysms of the infrarenal aorta. Its treatment is challenging and the best strategy is far from consensual. The authors report a case of a HIV + patient with multiple other co-morbidities, which was seen in the emergency department with fever and left back pain. These symptoms would prove to be in relation to a ruptured infectious aneurysm of the abdominal aorta. Facing this situation it was decided to select an endovascular technique with implantation of an aorto uni - iliac stent graft with a right-left femoro-femoral cross-over using a 8 mm PTFE graft and exclusion of the left common iliac . The patient didn't have any complication from the situation or the procedure, but died 18 months postoperatively because of a pneumonia caused by Pneumocystis jiroveci. Although it is not the ideal solution for the treatment of infectious elective aneurysms, we believe that endovascular treatment seems to be a viable option and should be taken into account in a subgroup of patients that for their co-morbidities are not good candidates for conventional surgery and for those in rupture, either as a bridge or as a final solution.
