Abstract

Mycotic abdominal aortic aneurysm (MAAA) is a rare but lifethreatening condition with an incidence of about 0.65-2% of all aortic aneurysms. MAAA have poor prognosis as they have tendency to grow rapidly and rupture and the patients often have severe comorbidities and coexisting septic conditions. Conventional surgical treatment is open surgery but is associated with high morbidity and mortality and can be very demanding or even impossible. Endovascular aneurysm repair (EVAR) is a less invasive but controversial alternative to conventional open repair of MAAA. A major disadvantage of EVAR is that the infected tissue, including the aneurysm itself, is not resected, which may facilitate reinfection, recurrent sepsis, and infection of the endoprosthesis. Methodology:  Three cases of MAAA are described; all treated with endovascular stent graft with variable configurations (2 cases treated with EVAR and 1 with surgeon modified Fenestrated EVAR). The clinical diagnosis of MAAA, was made by clinical presentation, results of hematologic tests and culture, and CT findings. All cases grew streptococcus pneumoniae on blood culture. All patients underwent successful placement of stent grafts for their aneurysms. All patients were given antibiotics preoperatively and postoperatively, initially with broad-spectrum antibiotics intravenously and later, when discharged from the hospital, oral treatment guided by culture results, when available. Antibiotic therapy was administered after consultation with infectious disease specialists.  No 30-day postoperative mortality was observed. Conclusion: Our short- term review shows that repair of MAAA can be accomplished with endovascular repair. This may be a safer alternative to open repair particularly in patients who are not suitable for conventional open repair.
