[Management of patients with coagulation disorder in oral and maxillofacial surgery. II. Management of patients with hypocoagulation caused by primary thrombocytopathy]. Il trattamento del paziente con difetto di coagulazione in chirurgia orale e maxillo-facciale. Nota II. Il management dei pazienti in stato ipocoagulativo a causa di una patologia primaria trombocitopatica.

Any oral and maxillo-facial surgical treatment, however urgent it may be, must not include pathological states in which the patient's life may be particularly at risk as, for example, with Disseminated Intravascular Coagulation (DIC) or thrombotic thrombocytopenic purpura. In this article the authors present the result of studies carried out on the nosology of thrombocytopathy from an odontostomatological point of view. Thrombocytopathy can be divided into two groups: the first including the pathologies with a predominant defective number of thrombocytes (i.e.: thrombocytopenia, thrombocythemia, thrombocyto-sis), the second including forms with predominant qualitative defects (commonly known as thrombocytopathies). The authors, after having presented in short the physiopathologic functions of thrombocytes, illustrate the clinical and therapeutic aspects of the most important thrombocytopathies. Morbus Maculosus Werhofii, Glanzmann's disease, Bernard-Soulier syndrome, thrombocytopathies from defective reaction of release, Thrombocytopathies from defective procoagulant activity of blood plaques, thrombocytopathies in linkage to other genetic anomalies, von Willebrand's pseudodisease and a lot of acquired thrombocytopathies are identified. In the last part the authors illustrate the most opportune clinical steps corresponding to the most important thrombocytopathies. The results obtained suggest the necessity of keeping to the management that was described, Actually a low percentage of accidents occurred only when the above-mentioned clinical processes were completely performed.
