Background: In this study, we present our early and mid-term results of endovascular aneurysm repair in patients with infrarenal abdominal aortic aneurysms.

Methods: Between December 2011 and January 2017, a total of 154 patients (136 males, 18 females; mean age 71.7 years; range, 55 to 94 years) who underwent endovascular aneurysm repair were retrospectively analyzed. Data including demographic characteristics of the patients, pre-procedural additional diagnoses, mortality and morbidity rates, length of intensive care unit and hospital stays, amounts of blood products used, complications and reinterventions were recorded.

Results: Seven patients underwent intervention in the emergency setting due to aneurysm rupture, while 147 patients received elective surgery. The mean follow-up was 35 (range, 12 to 72) months, the mean length of intensive care unit stay was 1.1 (range, 1 to 4) days, and the mean length of hospital stay was 3.1 (range, 3 to 7) days. A mean 0.3 units of erythrocyte suspension was used during the treatment. Endoleak developed in 16 patients, occlusion in the graft leg in two patients, increased aneurysmal diameter in six patients, and wound healing problems in five patients. Cross femoral bypass was applied in two patients, balloon dilation in three patients, proximal extension in three patients, and distal extension in four patients. Intraoperative mortality occurred in one patient. The total mortality rate was 7% and first 30-day mortality rate was 2%.

Conclusion: Our study results suggest that endovascular aneurysm repair has certain advantages including a low operative mortality rate, short intensive care unit and hospital stays, and less blood product use. In addition, this technique can be performed with regional anesthesia in high-risk comorbid patients.
