Endoleaks remain one of the most common indications for reintervention after endovascular aortic repair. Occasionally, aneurysm sac expansion will occur in the absence of a visible endoleak or due to endotension. We describe a case of continued sac expansion without an identifiable endoleak after endovascular aortic repair. Technical challenges during the case included a short distance from the renal arteries to the flow divider and a significant metal artifact. These challenges were addressed by shortening the gate of a Gore Excluder (W.L. Gore & Associates, Flagstaff, Ariz) to the desired length. The contralateral gate was preloaded to allow for use of the snare-ride technique for gate cannulation and overcome the metal artifact that was hindering visualization.
