The causes of vascular occlusion are also highly variable, ranging from thrombi triggered by the uncontrolled activation of coagulation mechanisms, on the one hand, to endothelial dysfunction or occlusion by material extrinsic to the coagulation system on the other. In a 2-part review, we look at the main causes of vascular occlusion and the key clinical and histopathologic findings. In this first part, we focus on vascular occlusion involving thrombi.enAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/CrioaglutininasCriofibrinogenemiaCrioglobulinemiaCryoagglutininsCryofibrinogenemiaCryoglobulinemiaEcthyma gangrenosumEctima gangrenosoPurpura fulminansPúrpura fulminansThrombosisTrombosisBlood CoagulationHumansThrombosisresearch article33045208open access10.1016/j.ad.2020.09.0062173-5778PMC7546665https://doi.org/10.1016/j.ad.2020.09.006https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7546665/pdf
