Failure of endovascular or conventional abdominal aortic aneurysm (AAA) repair may occur as a result of attachment site endoleak (type I) or paraanastomotic aneurysm and pseudoaneurysm formation. This study examined the results of the use of secondary endovascular grafts for the treatment of failed prior infrarenal AAA repair procedures. Forty-seven patients were treated with endovascular grafts. These included 14 patients with type I endoleaks (5 proximal, 8 distal, 1 proximal and distal) and 33 patients with paraanastomotic aneurysms after standard open surgical AAA repair (3 proximal aorta, 5 distal aorta, 21 iliac, 4 proximal and distal). The interval between the primary aortic procedure and the endovascular repair was significantly shorter for failed endovascular procedures (mean, 18.2 months; range, 1-42 months) than for failed conventional procedures (mean, 108.9 months; range, 12-216 months) (p < 0.01). The endovascular devices used for correction of the failed AAA repairs were Talent (23), physician-made (19), AneuRx (2), Vanguard (2), and Excluder (1). Transrenal fixation was used for repair of all proximal anastomotic failures. Mean follow-up after reintervention was 12.2 months in patients with failed endovascular grafts and 10.6 months in patients with failed conventional grafts. Patient demographics were as follows: average age, 78 years; 36 male and 11 female; and 4.1 comorbid medical conditions per patient. The endovascular graft was successfully deployed in all 47 cases; 1 patient experienced a persistent proximal attachment site endoleak after endograft deployment. Endovascular grafts may be used to treat previously failed endovascular and conventional AAA repair procedures with good short- and intermediate-term results. Endovascular treatments in these cases may avoid the difficulties of aortic reoperation or AAA repair in the setting of prior endovascular aortic grafting.
