Changes in plasma MMP-9 concentrations in the two patient groups. CEA: carotid endarterectomy group (striated); and CAS: carotid artery stenting group (grey). Samples: 1, preoperative values; 2, 60 min after cross-clamp release/stent insertion; 3, postoperative day 1; and 4, postoperative day 3. *: p < 0.05 compared to sample 1; and #: p < 0.05 compared to CAS
