A vascular graft is a medical device used to replace or bypass damaged blood vessels. It can be made from synthetic materials or biological tissues, and its primary purpose is to restore normal blood flow in patients with vascular diseases or injuries. Common conditions that may require a vascular graft include peripheral artery disease and coronary artery disease. These grafts are surgically implanted and can be used in various procedures, such as bypass surgery or vascular reconstruction. The success of a vascular graft depends on factors like the patient's overall health and the type of graft material used. Proper integration with the body's circulatory system is crucial for effective healing.
