Zenith Cook limb type IIIB endoleak causing aneurysm rupture five years after EVAR. (June 2015) - Mezes, Peter
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.
