- Abstract
Background: To confirm the activation of platelets (PLT) and explore the role of activated PLT in post-dissection inflammation.Method: An acute type A aortic dissection (AAD) canine model was established. Mean platelet volume/platelet count (MPV/PTC), platelet size distribution width (PDW), and inflammatory cytokines (tumor necrosis factor-α [TNF-α] and interleukin-6 [IL-6]) were measured between anesthetization and thoracotomy (T1), at the end of the operation (T2), and at 2 h (T3), 4 h (T4), and 6 h (T5) after the operation. Bivariate analysis was used to determine the correlations between the peak MPV/PTC, PDW, and inflammatory cytokines at T4.Result: An AAD canine model was successfully established. Both MPV/PTC and PDW values were significantly higher at T3-T5 than at T1 (P Conclusion: Activated PLT were identified after AAD, and played a critical role in the initiation of post-dissection inflammation.
