you have it correct. the dr is probably stenting the native artery that the graft is attached too. it is common but you are at 3.5 yrs andthats quick are you watching your bp and cholesterol? exercising? youmust change your lifestyle or he will eventually run out of options and you'll wind up with a re-do cabg and the morbidity rate increases dramatically. good luck.
The grafted arteries are good. He is stenting the original arteries. He stated that the grafted area was attached to a diseased artery, maybe he is trying to put more blood to the diseased artery hoping that more will pass thruogh.
Are you saying the procedure was to stent the graft and not the artery that had been by-passed. Sometimes the graft develops occlusions and then stented.
Quote "...the bypasses were clear and good, but he wanted to stent the old arteries that had severe blockage." Doesn't make much sense..if stents could have been a viable option before a by-pass, why a stent implant now?! If there is a deficit of blood/oxygen to a specific portion of the heart, it may be the intervention is to provide a collateral passage to the deficit area. But if the by-pass vessels were clear and good, it should be sufficient to provide an adequate blod supply. You may want to get another opinon. The proposed intervention is not without risks.
