A graft can be used for people with small veins.

A graft can indeed be used for people with small veins, making the statement true. In patients who have small or narrow veins that may not be suitable for traditional techniques such as venipuncture or where direct access is challenging, a graft provides an alternative approach for vascular access. Grafts, typically made of synthetic materials or sometimes from biologic tissue, can create a larger conduit for blood flow, enabling medical professionals to perform necessary procedures like dialysis or surgeries.

This use of grafts is particularly important in situations where the existing veins are inadequate due to their size or condition, allowing for effective treatment without compromising the patient's care. Thus, utilizing a graft can significantly enhance a patient’s treatment options and improve outcomes in situations where their anatomical differences may pose challenges.
