Thank you so much for the information. I will pass this on and hope we can encourage her to go on with her life..even thought she has this problem. She can move the hand and leg but has the tingling feeling all the time but can function.
It is very likely that she had a small stroke leading to those symptoms. It does occur very infrequently with bypass surgery, but is more likely in older patients. Assuming that she has no atrial fibrillaiton, which is also a common cause of stroke, I would have to say, based on the temporal relationship, that the stroke happened during the surgery. If in two years she has not recovered any function, it is unlikely that she will at this point.
