PS46. Frequency of Thoracic and Abdominal Aortic Aneurysms in Patients Treated for Popliteal Aneurysms

Abstract

Objectives: Commercially available Aortouniiliac (AUI) devices are most often described as rescue therapy for complications of endovascular aneurysm repair. They have also been described to be useful in several settings including ruptured AAA and difficult aortoiliac anatomy. We report on the indications and outcomes with AUI devices in a single center. Methods: We retrospectively identified all patients who underwent AUI repair in a single center during a five-year period. Patients were evaluated for indications of AUI placement, complications of surgery, and overall mortality. Patient demographics, indications for procedure, perioperative outcomes and mortality data were analyzed. Results: There were 38 patients identified having undergone AUI with femoral-femoral bypass with a mean age of 75.6 8.9 years. Cook converters including the Renu were used in 97% of the cases. The indications were elective aneurysm repair with anatomic constraints (47%), complications of previous EVAR (29%), rupture (13%) and aortoiliac occlusive disease (11%). Of those patients who underwent elective aneurysm repair 35% had concomitant iliac aneurysms and 29% had occlusive disease in the aortoiliac system. Non-aneurysm related mortality was 26% within the five year period. Of the patients alive, the mean overall follow-up is 28 (9-62) months. There were no aneurysm related deaths identified. There was an 18% complication rate. Of those complications identified, 1 was a major endoleak requiring secondary intervention. The remaining complications included femoral wound infections (n 3), femoral-femoral bypass occlusion (n 2) and pulmonary complications (n 1). Conclusions: AUI devices are an effective treatment for aortoiliac aneurysms with challenging anatomy, rupture, or as rescue endoluminal therapy. They may also have a role in patients with aortoiliac occlusive disease. Further research is needed to delineate this patient subset.
