Abstract
Endovascular abdominal aortic aneurysm repair (EVAR) for degenerative abdominal aortic aneurysm (AAA) requires complete aortic exclusion to prevent ongoing aneurysmal degeneration in a diseased aorta. Focal infrarenal aortic pathology, such as penetrating atherosclerotic ulcer (PAU), saccular aneurysm, and/or intramural hematoma (IMH) may not necessitate complete aortic coverage. Here, we review our experience with endovascular management of focal aortic pathology with limited aortic coverage. A prospectively maintained institutional database of patients undergoing EVAR was retrospectively reviewed to identify all patients treated with a nonbifurcated device (Current Procedural Terminology code: 34,800). Patients without a diagnosis of PAU, saccular aneurysm, IMH, or iatrogenic pseudoaneurysm were excluded. Medical records and imaging studies were reviewed for confirmation of focal aortic pathology. Preoperative imaging and intraoperative details were reviewed. Outcome measures included technical success, symptom-free survival, and freedom from reintervention. Eight patients were identified who underwent repair of a focal aortic defect with an endovascular tube graft from 2004-2011. Six patients underwent surgery for 7 saccular...Continue Reading
