[Current aspects of arterial anti-thrombosis prophylaxis]

New prophylactic strategies for arterial thrombosis are built up following new discoveries about the thrombo-resistance of the vascular endothelium. To cope with the complexity of the interactions between platelets, erythrocytes and endothelium, it is logical to propose a multivalent prophylaxis, potent enough to control the multiple thombogenic factors. In this prospect, the combination acetyl-salicylic acid with dipyridamole presents an obvious complementarity, until confirmation of the clinical activity of other combinations.
