Abstract

Purpose: To describe results of AFX unibody stent-graft treatment for TransAtlantic Inter-Society Consensus (TASC) D aortoiliac occlusive disease (AIOD) with coexistent abdominal aortic aneurysm (AAA). Methods: A retrospective analysis was conducted of 21 consecutive patients (mean age 73.6±6.4 years; 17 men) with TASC D AIOD plus AAA (diameter >3.5 cm) treated electively using the AFX stent-graft. Common iliac artery (CIA) and external iliac artery (EIA) stenosis or occlusion was reported. Outcome measures were technical and clinical success, improvement in ankle-brachial index (ABI), and improvement in Rutherford category. Immediate and midterm patency, AAA exclusion, major adverse events (MAE), and mortality were also evaluated. Results: After AFX deployment (100% technical success), 18 EIAs required adjunctive stenting (none required in the CIA). One patient required a reintervention for closure device failure. At 30-day follow-up, no death or MAE was recorded. Improvement in ABI was registered in all patients (mean 0.91±0.11), with 100% primary patency. At a mean follow-up of 25.2±11.1 months, primary patency was maintained in all cases. No death or amputation occurred; 2 patients had a myocardial infarction. Improvement in ABI was maintained (0.88±0.13) as well as Rutherford category. Conclusion: This study examined the use of the AFX unibody stent-graft for the treatment of TASC D AIOD with concomitant AAA. The AFX stent-graft appears to be a safe and effective solution for these complex lesions, with low morbidity and mortality.
