Path of DIC

Answer 32

thrombin -> fibrinogen to fibrin -> fibrin clots in microcirculation decrease fibrinogen,PT, PLT, factor V and VIII are reduced activates fibrinolytic system which lyses fibrin clots into fibrin degradation products hemorrhage results from anticoagulantnt activity of FDPs and depletion of coag factors
