My 83 year old mother-in-law had a mild stroke last Sunday (3/13/16). It was discovered her left cardioid artery is 70% blocked and the right side, which is the side of the stroke is 50% blocked. The doctors are recommending surgery on the right side first, since that is the side of the stroke. She was moved to acute rehab first to get stronger and to give a diagnosed UTI time to clear up. Is there a time frame for the most success for both cardioid surgeries. The surgeon said 1-2 weeks after the stroke and neurologist said it is elective and can be done in a few weeks after she gets stronger.
