Abstract
Purpose
Endovascular aortic aneurysm repair (EVAR) has revolutionized the treatment of abdominal aortic aneurysms. Type I and III endoleaks require prompt, definitive repair or explantation. We review a single center experience of endovascular treatment of type I and III endoleaks.
Materials and Methods
Retrospective review of 22 patients who underwent endovascular intervention for remediation of proximal or distal seal zone endoleaks.
Results
Median age was 77 years. Median time interval from EVAR to reintervention was 4 years (range, 1 month–11 years). Sixteen patients (73%) had radiological evidence of endoleak and/or expanding sac size and 6 (27%) had contained rupture. Nine patients underwent a total of 12 endovascular reinterventions before this salvage procedure. Stent grafts used at the original procedure were: AneuRx (n = 10), Excluder (n = 7), Ancure (n = 3), Zenith (n = 1), and custom made (n = 1). Endoleaks treated were type Ia (n = 11), Ib (n = 12), and type III (n = 3). Interventions included: proximal cuff insertion with or without Palmaz stent insertion (n = 8), distal limb extension (n = 2), stent graft relining (n = 6), embolization of hypogastric artery and iliac limb extension (ILE) (n = 5), and aorto-uni-iliac stent graft (AUI) with femoral–femoral crossover (n = 1). One patient who had a rupture died of multiorgan failure. Two patients needed additional reinterventions for endoleaks. Median length of hospital stay was 1 day.
Conclusion
Lifelong surveillance after EVAR is advocated because of the potential of delayed type I or III endoleaks, which mandate definitive treatment. Fortunately, most delayed type I and III endoleaks can be successfully corrected with endoluminal interventions rather than resorting to explantation of the endograft.
