Endovascular repair of mycotic aortic aneurysms confers good medium-term outcomes and aneurysmal sac resolution.

Introduction: Mycotic aortic aneurysm (MAA) is a life-threatening condition. Endovascular repair (EVAR) of aortic aneurysms has been found to be a safe and effective alternative to open repair. We aimed to present the short- to medium-term outcomes for EVAR of MAA in our cohort.

Methods: We conducted a retrospective study of 23 consecutive patients with MAA who underwent EVAR in our hospital from January 2008 to July 2017.

Results: The mean age of our study population was 62 years. The mean aneurysmal size was 3.2 cm. Abdominal MAAs (n = 16, 70%) were the most common, followed by thoracic MAAs (n = 4, 17%). There was no 30-day mortality in our cohort. Endoleak (Types 1, 3, 4) was detected in 3 (13%) cases. At the one-month surveillance computed tomography aortogram, all patients had a reduction in aneurysmal size and 5 (22%) had complete aneurysmal sac resolution. 7 (30%) patients had sac resolution at six months and 8 (35%) patients, at 12 months. The overall survival was 91%, 80% and 61% at one, 12 and 60 months, respectively.

Conclusion: EVAR is a feasible and durable method for the repair of MAA, with a five-year overall survival of 61%. All patients in our study had a reduction in aneurysmal size at one month, with 65% having complete aneurysmal sac resolution by 12 months.
