HAA was defined as presence of aneurysm at any point in iliac arteries (≥17 mm in males, ≥15 mm in females), severe (≥50%) artery stenosis, or severe tortuosity of iliac artery. Patients" demographic data, operation details, 30-day, and one-year outcomes were recorded.

Results: Of the 31 patients, 14 (45%) had HAA. Technical success for both groups was 100%. Type 1a endoleak was not seen on control angiography in both groups. More adjunctive intraoperative procedures were necessary for type 1b endoleaks in patients with HAA (p=0.019). Total usage of contrast agent was higher in HAA group (p=0.014). At 30-day follow-up, creatinine level was higher in HAA group (p=0.009). Four patients with HAA developed acute kidney failure (p=0.034). Durations of operation and hospital stay were longer in HAA group (p=0.041, p=0.019). At one-year follow up, no significant difference was found between two groups in all-cause mortality. Three patients with HAA still undergo dialysis for chronic renal failure (p=0.042).

Conclusion: Abdominal aortic aneurysm repairs were found to be associated with more requirement of adjunctive procedures, more contrast agent usage, higher creatinine levels, more frequent development of kidney failure, and prolonged duration of hospital stay in octogenarian patients with HAA compared to those with FAA.
