graft surveillance
Regular monitoring of bypass grafts to detect stenosis or failure.
Full Definition
Systematic follow-up protocol using duplex ultrasound, ankle-brachial indices, and clinical assessment to monitor bypass graft patency and detect developing stenosis before occlusion occurs. Surveillance protocols vary by graft type and location, with prosthetic grafts requiring different monitoring than autogenous vein grafts. Documentation must include specific surveillance intervals, velocity criteria for intervention, and protocols for graft revision.
Usage
Usage note: Typically refers to duplex ultrasound-based monitoring programs.
In Context
- "Graft surveillance at six months revealed elevated velocities concerning for stenosis." — Follow-up assessment
- "The surveillance protocol includes duplex ultrasound at 1, 6, and 12 months post-operatively." — Clinical protocol
