BACKGROUND: This is a single institutional review of aortoiliac pseudoaneurysm of various aetiologies managed with endovascular stent graft repair.

METHODS: From 2009 to 2014, 16 patients had endovascular stent graft inserted for pseudoaneurysm of the thoracic aorta, abdominal aorta and iliac arteries in Hospital Kuala Lumpur. Co-morbidity, causative agents, in-hospital mortality, complications and outcomes were examined.

RESULTS: The average age was 59.1 years (range 36-77). Comorbidities include hypertension, diabetes mellitus, tuberculosis, prior infection and previous open aneurysmal repair. All patients had raised WBC (>10.0x10(9) /L), ESR or Creactive protein on admission while 50% of patients had fever. Blood cultures were positive in 4 patients. All patients were given antibiotics. Only one in-hospital mortality was noted at day-47 post-procedure. Two patients died of aortoenteric fistula at district hospital eight and 16 months later. One patient died of chronic graft infection two years later. One died of unrelated cause. One patient developed type IB endoleak from internal iliac artery two years later and surgical ligation was performed. The average follow up was 15.8 months.

CONCLUSION: Endovascular stent graft repair for pseudoaneurysm is a viable option compared to open surgery. It is less invasive, has lower operative morbidity and fair outcomes. However, some cases may be due to inflammatory aortitis instead of infective pseudoaneurysm, given the frequent culture-negative results. In order to obtain high yield of bacteria culture for infected pseudoaneurysm, open repair with tissue culture is still the main mode of treatment especially for patients with low comorbidity.
