Zenith Cook limb type IIIB endoleak causing aneurysm rupture five years after EVAR

Abstract

Type III endoleaks are rare late complications of endovascular abdominal aortic aneurysm repair. The aneurysm sac is pressurised either through disconnection of modular components (type IIIA) or a defect in the graft fabric (type IIIB). We report the endovascular treatment of a ruptured infrarenal aortic aneurysm five years after elective endovascular abdominal aortic aneurysm repair caused by a type IIIB endoleak secondary to probable graft material erosion of the contralateral limb. This is the first report of a late aneurysm rupture caused by fabric defect in a Cook Zenith limb. The case highlights the potential serious consequences of minimal migration of the device and the importance of landing the proximal fixation in healthy aorta.
