Is it true that a vascular bypass surgery is only good for 5-10 years? what will happen to the pt after that period? will she need amputation then?

Depends: The duration of a bypass depends on many factors including the vein or graft used. Other procedures can be done to extend the life of the graft. The best patients can do to maintain a graft is to watch their cholesterol with the help of their physicians, use aspirin, and to stop smoking.

Vascular Bypass Life: Yes, the average life-expectancy of a vascular bypass does range 5-10 years for most patients. Heart bypasses tend to last longer than bypasses in other locations of the body. Bypass that uses vein tend to last longer than those that utilize synthetic conduits, such as gortex or dacron velour grafts. Bypass life can be extended by doing stents or angioplasty or even surgical revision over time.

Cardiovascular risk : Progression and recurrence of vascular disease is dependent upon taking appropriate medication directed at prevention of blood clots and atherosclerosis. This entails antiplatelet medications and careful attention to the control of all known cardiovascular risk factors, including diabetes, blood pressure, lifestyle, lipids, smoke cessation and others.
