Fibrosis score atdifferent times and revascularization. a) In the first hour and b) up to 24 h’ absence of fibrosis with absence of red signal. In the following hours c) > 24 h to 48 h, d) > 48 h to 72 h, e) > 72 h there is an increase in the signal (PricoSirius Red/Fast Green stain; 10x magnification). f) The black arrow indicates revascularization in the old thrombus after 72 h (Immunohistochemistry for anti-CD31 antibody; × 10 magnification)
