[Patient at hemorrhagic risk. Prevention and local control]. / Il paziente a rischio emorragico. Profilassi e accorgimenti locali.

The Authors make a short analysis of the main alterations of the coagulative system and of the anticoagulant medicines, used in patients with normal hemostasis, but suffering from cardiovascular disease. It is underlined the importance of a close collaboration between the odontologist and the hematologist or the general practitioner, to be able to make a correct pre-operating prophylaxis, if necessary. All the local procedures that the odontologist must prepare to prevent or at least stop the possible hemorrhagic troubles are finally analysed.
