Percutaneous closure of aortic pseudoaneurysm by Amplatzer occluder device-case series of six patients

Abstract

Thoracic pseudoaneurysms are rare variety of aortic disorders. Although mostly asymptomatic, they represent potentially fatal conditions (Sullivan et al., Chest 1988;93:138-143; Razzouk et al., Ann Surg 1993;59:818-823) that are traditionally treated surgically. False aneurysms of aorta are usually a late complication of previous surgical procedure (Sullivan et al., 1988)-especially reconstructive surgery, trauma (Razzouk et al., 1993), and rarely infection (Sanchez-Recalde et al., J Am Coll Cardiol 2003;41:152-154). Surgical management is often complicated by poor outcomes with high morbidity and mortality (Mulder et al., Arch Surg 1998;133:45-49). Endovascular treatment is emerging as promising options for aortic diseases with fewer complications. We report a series of six cases at a single center where Amplatzer device was used to treat thoracic aortic pseudo aneurysm. To our knowledge only one series of three cases (Kanani et al., Catheter Cardiovasc Interv 2007;69:146-153) and few case reports (Bashi et al., Catheter Cardiovasc Interv 2005;65:547-551) of successful closure have been published previously. Our case series is the largest, so far, including mortality and specifically the preprocedural and postprocedural CT angiographic assessment of the pseudoaneurysms.
