Graft patency longer: A well cared for av graft can last decades. If the subclavian or axillary area becomes stenosed then a venoplasty or stent can extend the use of the graft for as long as the stenosis is resolved. The key to a good graft is avoiding stenosis. But next best is treating it. Hope this helps. Make sure to get follow up 3-6 months later to keep stenosis resolved.
