[Angiology and hemostasis: what's new in 2023].

We discuss four topics among the angiology and hemostasis studies of importance in 2023. The BASIL-2 study provides new data for the management of chronic limb-threatening ischemia by comparing surgical and endovascular treatment. The new classification of antiphospholipid antibody (aPL) syndrome integrates new clinical elements and gives a different weight among the isotype and titer of aPL. Concizumab, an antibody targeting the tissue factor pathway inhibitor, broadens the therapeutic arsenal for hemophilia A and B as evidenced by the results of the EXPLORER 7 study. The PREVENT-CLOT and CASTING study focus on the prevention of thrombosis after trauma, by testing the role of aspirin or the lack of thromboprophylaxis, respectively.
