Endovascular repair of an abdominal aortic aneurysm under local anesthesia using bifurcated stent graft in a patient with iliac artery chronic occlusion:A case report

Abstract

Background: There are some clinical conditions described in literature which limit the application of full endovascular aneurysm repair, and the most important of these limitations are inappropriately short and angled aneurysm neck, narrow terminal aorta, and curved and very small diameter or highly calcified iliac arteries that make access difficult, and unilateral iliac artery occlusion is another one of these limitations, which is less frequently observed.Case report: In our case report, we present a patient whose abdominal aortic aneurysm was considered to be high risk for classical open surgical repair. Our patient has a unilateral iliac artery occlusion co-existing with abdominal aortic aneurysm and the occluded left common iliac artery and severely stenotic external iliac artery segment was applied percutaneous transluminal balloon dilatation and after which abdominal aortic aneurysm was successfully treated with standard endovascular aneurysm repair.Conclusion: A standard successful endovascular aneurysm repair procedure was applied for the patient who did not develop any intraoperative complications. The left iliac artery blood flow was also ensured by the dilatation of occluded iliac artery segment, simultaneously. When there are such limitations related to the iliac artery as iliac artery occlusion, the standard endovascular aneurysm repair procedure combined with invasive techniques for iliac artery revascularization is a practical and safe treatment option which reduces the procedural morbidity and mortality compared to the other treatment options.
