An operative method for surgical revision of a late failure after endovascular repair of an abdominal aortic aneurysm.
Endoleak is a well-recognized complication of endovascular aortic exclusion stent-grafts. The Vanguard device is anchored into the proximal aorta by an expandable stent surmounted by a circular array of metal hooks. Attempted removal of the whole prosthesis may therefore be technically difficult and result in damage of the aortic wall. Surgery for endoleak may be complicated and carry a mortality rate of 20% to 40%. We describe a simple surgical technique for repair of endoleaks associated with a Vanguard stent-graft, which would be applicable to other such devices. This method involves minimal disruption of the proximal stent and avoids problems that may arise from an attempt to completely remove the endovascular device.
