The oc-currence of 2 strokes more than 2 days after surgery, but within 30 days, was a pattern identical to that observed in the nonsurgical group of 98 patients, which had 2 ipsilat-eral strokes within 30 days of randomization.Of the 14 strokes occurring within the 30-day post-operative period, 2 were disabling at the last follow-up (Barthel Index < 12) and 1 was fatal.
