“…AUI grafts represented only 7.5% of the total number of the performed EVAR procedures in our center. This is more or less similar to the percentage published in a recent study by Dortch et al [ 19 ]. This may render our analysis prone to some bias.…”

We investigated the safety and efficacy of primary aorto-uni-iliac (AUI) endovascular aortic repair (EVAR) without fem-fem crossover in patients with abdominal aortic aneurysm (AAA) and concomitant aortoiliac occlusive disease. 537 EVARs were implemented between 2002 and 2015 in University Hospital Galway, a tertiary referral center for aortic surgery and EVAR. We executed a parallel observational comparative study between 34 patients with AUI with femorofemoral crossover (group A) and six patients treated with AUI but without the crossover (group B). Group B patients presented with infrarenal AAAs with associated total occlusion of one iliac axis and high comorbidities. Technical success was 97% (n = 33) in group A and 85% (n = 5) in group B (P = 0.31). Primary and assisted clinical success at 24 months were 88% (n = 30) and 12% (n = 4), respectively, in group A, and 85% (n = 5) and 15% (n = 1), respectively, in group B (P = 0.125). Reintervention rate was 10% (n = 3) in group A and 0% in group B (P = 0.084). No incidence of postoperative critical lower limb ischemia or amputations occurred in the follow-up period. AUI without crossover bypass is a viable option in selected cases.

“…Prior studies have focused on medium-and long-term durability of this procedure by focusing on femorofemoral bypass-specific and device complications. 14 Although EVAR with an AUI graft may provide the possibility of intervention for a greater anatomic range of aneurysms, our study shows that this procedure is associated with a significant 33% rate of occlusion and stenosis of the contralateral IIA. Given that the selection of AUI endovascular devices over bifurcated devices in a given patient may be highly influenced by the presence of iliac artery tortuosity and aortic bifurcation or by iliac occlusive disease, that iliac malperfusion occurs in this patient population is perhaps not surprising.…”

Our findings suggest that AUI EVAR with femorofemoral bypass is associated with a significant incidence of contralateral IIA malperfusion on postoperative CT imaging. Occlusion appears to occur early in the postoperative period in most patients, and patient-reported buttock claudication is observed significantly more frequently in patients with an occluded IIA compared with those with a patent IIA. More serious pelvic ischemic complications were not seen in this series. Further study is required to determine whether modification of the procedure can prevent contralateral IIA occlusion and the development of buttock claudication.
