graft patency

Graft patency refers to the openness and proper function of a blood vessel graft used to bypass blocked arteries, often in heart surgeries. When a graft remains unobstructed and allows blood to flow freely, it is considered patent. Maintaining graft patency is crucial for the surgery's success, as blockages or narrowing can reduce blood flow, leading to recurring symptoms or complications. Healthcare providers monitor graft patency through imaging tests to ensure the bypass continues to work effectively over time.
