Background & objectives, Ischaemic stroke is a life burdening disease for which carotid endarterectomy (CEA) is considered a gold standard intervention. Pro-inflammatory markers like matrix metalloproteinases (MMPs) and their inhibitors (TIMPs) and S-100 Beta (S100B) may have a role in the early inflammation and cognitive decline following CEA. This study was aimed to describe the perioperative time courses and correlations between of MMP-9, TIMP-1 and S100B following CEA. Methods, Fifty four patients scheduled for CEA were enrolled. Blood samples were collected at four time points, T1, preoperative, T2, 60 min after cross-clamp release, T3, first postoperative morning, T4, third postoperative morning. Twenty atherosclerotic patients were included as controls. Plasma MMP-9, TIMP-1 and S100B levels were estimated by ELISA. Results, TIMP-1 was decreased significantly in the CEA group (P1-4 in the CEA group (P3 compared to T1 (P2 and T3 (P2 and decreased on T3-4 compared to T1. Interpretation & conclusions, Our study provides information on the dynamic changes of MMP-9-TIMP-1 system and S100B in the perioperative period. Preoperative reduction of TIMP-1 might be predictive for shunt requirement but future studies are required for verification.
