Description
Tayeh and colleagues reported two patients whose repaired abdominal aortic aneurysms sprang a hidden leak years later through a tear in the graft fabric itself. The repair, called EVAR, lines the weakened aorta with a fabric stent, and this leak type, IIIb, is rare but can be fatal. Their 2026 case report describes leaks surfacing 60 and 48 months after implantation of two different commercial grafts.
Both leaks resisted easy diagnosis because routine imaging has limited sensitivity for tiny fabric defects. Warning signs included a dense area on scans and a slowly enlarging aneurysm sac, even without a visible leak channel. Open surgical repair remained the definitive fix once the problem was recognized. Tayeh urges lifelong surveillance after EVAR, since no device is immune to late fabric failure and early action prevents rupture.
