RESUMO

PURPOSE: Diabetes mellitus indicated poor clinical prognosis for patients with acute ischemic stroke. Furthermore, diabetes mellitus could also impact the hemostatic system, while its influence on the histological composition of thrombus is unclear. METHODS: Consecutive patients with retrieved clots were included. Histologic staining for thrombus included hematoxylin and eosin, Martius Scarlet Blue, immunohistochemistry for von Willebrand factor. The differences in clot composition were compared according to diabetes mellitus history or hyperglycemia (≥7.8 mmol/L) on admission. RESULTS: A total of 52 patients were included; half of them were diagnosed as diabetes mellitus previously. Diabetic patients showed higher serum glucose on admission (8.90 vs. 7.40, p = 0.012). The baseline characteristics (expect smoking history and thrombus location), procedural, and clinical outcomes were similar between diabetic patients and nondiabetic patients. As for histologic composition, thrombus in patients with diagnosed diabetes mellitus had more fibrin (44.2% vs. 28.3%, p = 0.004) and fewer red blood cells (26.0% vs. 42.9%, p = 0.013) and equivalent content of platelets (24.0% vs. 21.5%, p = 0.694) and von Willebrand factor (0.041 vs. 0.031, p = 0.234) than patients without diabetes mellitus. However, there was no statistical difference in the content of red blood cells (41.6% vs. 27.3%, p = 0.105), fibrin (37.6% vs. 34.3%, p = 0.627), platelets (21.2% vs. 24.2%, p = 0.498), and von Willebrand factor (0.038 vs. 0.034, p = 0.284) between patients with or without hyperglycemia on admission. CONCLUSION: Clots in diabetic patients had more fibrin and fewer erythrocyte components compared with patients without diabetes mellitus, while hyperglycemia on admission did not show association with clot composition. Further studies are needed to confirm these results.
