An Endovascular-First Approach for Aortoiliac Occlusive Disease is Safe: Prior Endovascular Intervention is Not Associated with Inferior Outcomes after Aortofemoral Bypass

Although prior endovascular intervention is a risk factor for inferior outcomes after infrainguinal bypass, there are few studies evaluating the effect of prior aortoiliac endovascular intervention (AIEI) on outcomes after aortofemoral bypass (AFB). We sought to determine if prior AIEI was predictive of adverse events after AFB. The Vascular Quality Initiative was queried for all patients who underwent AFB form 2009 to 2019. Urgent/emergent cases and repeat procedures were excluded. Primary outcomes were major perioperative complications, major adverse limb event (MALE)-free survival, and long-term survival. Multivariable logistic regression identified predictors of major complications. Predictors of MALE-free survival were identified with Cox proportional hazards modeling. There were 3,056 patients who underwent AFB; 618 had a prior AIEI. Mean age was 60.3 ± 8.7 years, and 58.7% of patients were men. There was no difference in major complications between the 2 groups (AIEI: 23.8%, no AIEI: 24.5%; P-value = 0.70). Factors associated with major complications were chronic obstructive pulmonary disease (odds ratio [OR]: 1.28, 95% confidence interval [CI]: 1.07–1.54; P = 0.008), simultaneous lower extremity intervention (endarterectomy, bypass, or transluminal intervention, OR 1.41, 95% CI: 1.18–1.69; P
